Product details
Overview
P6SMB75CA-M3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 75 V standoff voltage (VWM), 103 V maximum clamping voltage (VC) at 5.8 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It protects signal lines and power rails in automotive sensor interfaces, industrial I/O modules, and telecom line cards against ESD and inductive switching transients.
For engineers reviewing the P6SMB75CA-M3/5B datasheet, P6SMB75CA-M3/5B pinout, P6SMB75CA-M3/5B application, or P6SMB75CA-M3/5B equivalent, key selection criteria include bidirectional clamping symmetry, low incremental surge resistance, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance (M3 suffix), and AEC-Q101 qualification readiness via HM3 variant.
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical breakdown behavior in both polarities-VBR min/max = 71.3 V / 78.8 V at 1 mA test current, enabling consistent transient suppression on AC-coupled or floating lines. Its glass-passivated junction ensures stable leakage (<1 μA at VWM) and fast response time (<1 ns), critical for safeguarding high-speed analog inputs and microcontroller GPIOs.
The SMB package delivers 100 °C/W junction-to-ambient thermal resistance and supports automated SMT placement. With 150 °C max junction temperature and 5.0 W steady-state power dissipation, it sustains repetitive surge events under derated conditions per Figure 2, while maintaining clamping integrity across -65 °C to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 64.1 V - Maximum continuous reverse voltage before conduction; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 71.3–78.8 V at 1 mA - Symmetrical avalanche onset in both directions; ensures predictable turn-on during bidirectional surges. |
| VC (Clamping) | 103 V at 5.8 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case transient; limits stress on downstream ICs. |
| PPPM | 600 W - Surge energy handling capacity; supports robust protection against lightning-induced or inductive kickback events. |
| IPPM | 5.8 A - Peak pulse current capability; determines minimum trace width and PCB copper area required for thermal management. |
| TJ max | +150 °C - Enables operation in under-hood automotive or high-temperature industrial enclosures without derating. |
| Package | SMB (DO-214AA) - Standardized 2-pin SMT outline with 5.59 mm × 4.06 mm footprint; compatible with JEDEC MS-012AC and IPC-7351B. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are functionally symmetric; both leads serve as interchangeable surge current paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge current entry (negative polarity event) | Conducts transient energy into device during negative-going overvoltage; shares identical clamping behavior with cathode. |
| Cathode | Surge current entry (positive polarity event) | Conducts transient energy into device during positive-going overvoltage; electrically mirrored to anode for bidirectional symmetry. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC characteristics in both polarities-enables single-device protection of AC signals, differential buses, or ungrounded circuits. |
| 600 W peak pulse power | Handles high-energy transients (e.g., ISO 7637-2 Pulse 1/2b/5a) without degradation when mounted on 5.0 mm × 5.0 mm copper pads. |
| MSL Level 1 rating | Zero floor life limitation; supports unlimited exposure to ambient humidity prior to reflow-eliminates bake requirements in production. |
| Halogen-free & RoHS-compliant (M3) | Fulfills IEC 61249-2-21 and JEDEC J-STD-609A Class 1 requirements; suitable for green manufacturing and export-regulated markets. |
| Low clamping ratio (VC/VBR) | 103 V / 75 V ≈ 1.37 - Tighter than typical TVS diodes (often >1.45); reduces voltage overshoot margin needed in protected circuit design. |
Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and MEMS pressure sensor outputs from load dump and ESD in engine control units. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed directly at connector entry point, clamping fast-rising spikes before they reach signal conditioning amplifiers. Use Value: Prevents latch-up or gate oxide damage in 3.3 V/5 V interface ICs by limiting transient voltage to ≤103 V with sub-nanosecond response. |
Use Scenario: Safeguarding 4–20 mA current loop receivers and ADC front-ends in programmable logic controllers exposed to relay coil flyback and field wiring surges. IC Role / Device Role / Timing Role: Bidirectional voltage clamp across input terminals, absorbing ±1 kV EFT bursts per IEC 61000-4-4 without affecting DC accuracy. Use Value: Maintains signal integrity during repeated surge events due to low incremental resistance (ΔV/ΔI ≈ 17.6 Ω), minimizing voltage sag across protected node. |
| Telecom Line Card Protection | Consumer USB Port ESD Guard |
|
Use Scenario: Shielding Ethernet PHY magnetics and PoE injectors from lightning-induced surges on outdoor-facing network ports. IC Role / Device Role / Timing Role: Primary-level TVS placed upstream of gas discharge tube (GDT) secondary protection, diverting initial 600 W surge energy. Use Value: Achieves coordinated staging with GDTs via precise VC matching-ensures TVS triggers first without overstressing downstream components. |
Use Scenario: Adding robust ESD immunity to USB 2.0 data lines (D+/D−) and VBUS in smart home hubs and set-top boxes. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF typical at 0 V) bidirectional clamp integrated adjacent to USB connector, meeting IEC 61000-4-2 ±15 kV contact discharge. Use Value: Preserves signal rise/fall times (≤1 ns response) while limiting ESD-induced ground bounce to <103 V-prevents false resets in connected peripherals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75CA | Same VWM/VC, but lower PPPM = 400 W; SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy transients (e.g., IEC 61000-4-2 only); unsuitable for ISO 7637-2 Pulse 5a. | Select when board space is constrained and surge threat level is ESD-only-not for automotive load dump. |
| 1.5SMC75CA | Same electrical specs, but larger SMC (DO-214AB) package; higher IPPM = 6.5 A and improved thermal performance (RθJA = 65 °C/W). | Better suited for high-repetition-rate surges in motor drives; requires larger PCB real estate. | Choose for industrial inverters or power supplies where sustained thermal cycling occurs and layout allows SMC footprint. |
Compared with SMAJ75CA and 1.5SMC75CA, P6SMB75CA-M3/5B delivers optimal balance of surge robustness (600 W), compact SMB footprint, and halogen-free compliance-making it preferred for space-constrained automotive and telecom designs requiring AEC-Q101 readiness.

FAQ
What is the clamping voltage of P6SMB75CA-M3/5B at its rated peak pulse current?
The P6SMB75CA-M3/5B has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The P6SMB75CA-M3/5B maintains this clamping performance across its full operating temperature range.
Is P6SMB75CA-M3/5B suitable for automotive applications requiring AEC-Q101 qualification?
The P6SMB75CA-M3/5B itself is not AEC-Q101 qualified; however, it belongs to the P6SMB family for which Vishay offers AEC-Q101 variants-specifically the HM3 suffix (e.g., P6SMB75CAHM3_B/I). The M3 suffix indicates halogen-free RoHS compliance and commercial-grade qualification. For automotive use, engineers should specify the HM3 version to ensure full AEC-Q101 compliance while retaining identical electrical parameters and SMB packaging.
How does the bidirectional nature of P6SMB75CA-M3/5B affect its PCB layout compared to unidirectional TVS diodes?
The P6SMB75CA-M3/5B has no polarity marking and exhibits symmetrical VBR and VC in both directions, eliminating orientation constraints during placement. Unlike unidirectional TVS diodes-which require strict cathode alignment toward the protected IC's power rail-the P6SMB75CA-M3/5B can be rotated 180° on the PCB without functional impact. This simplifies automated assembly and reduces risk of misplacement in differential or floating signal paths.
What is the thermal resistance of P6SMB75CA-M3/5B, and how does it influence PCB copper pad design?
The P6SMB75CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To sustain repetitive surge duty cycles, designers must allocate at least this pad area per lead. Reducing pad size increases RθJA, risking thermal runaway during high-frequency transients; increasing pad area or adding internal copper planes lowers RθJA and improves power handling margin for the P6SMB75CA-M3/5B.
Does P6SMB75CA-M3/5B meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, the P6SMB75CA-M3/5B meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This means the device has unlimited floor life at ≤30 °C/60% RH and requires no baking prior to soldering-even for lead-free processes. The M3 suffix confirms halogen-free molding compound and matte tin plating compliant with J-STD-002 and JESD 22-B102, ensuring reliable wetting and intermetallic formation during P6SMB75CA-M3/5B assembly.
