Product details
Overview
P6SMB75CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal and power lines. It features a 75 V standoff voltage (VWM), 103 V maximum clamping voltage at 5.8 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform. It is AEC-Q101 qualified and RoHS-compliant, suited for automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the P6SMB75CAHE3/5B datasheet, P6SMB75CAHE3/5B pinout, P6SMB75CAHE3/5B application, or P6SMB75CAHE3/5B equivalent, key selection criteria include bidirectional clamping performance, AEC-Q101 qualification status, SMB (DO-214AA) package thermal resistance (RθJA = 100 °C/W), and compliance with IEC 61000-4-2/4-4/4-5 transient immunity requirements.
Technical Context
The P6SMB75CAHE3/5B operates as a bidirectional avalanche diode, symmetrically clamping both positive and negative transients above its breakdown voltage range of 71.3–78.8 V at 1 mA test current. Its glass-passivated junction ensures stable leakage (<1 μA at 64.1 V) and fast response time (<1 ns), enabling effective suppression of ESD and lightning-induced surges.
Thermally, it supports operation from –65 °C to +150 °C junction temperature, with derating applied above 25 °C ambient per Figure 2. The device uses a low-inductance SMB (DO-214AA) package optimized for automated placement and meets J-STD-020 MSL Level 1 reflow profile (peak 260 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 64.1 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown) | 71.3–78.8 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping) | 103 V at 5.8 A (10/1000 μs) - Peak voltage seen by protected circuit under rated surge; critical for downstream IC survivability. |
| PPPM | 600 W - Peak pulse power handling capacity; determines robustness against 8/20 μs or 10/1000 μs surge events. |
| IPPM | 5.8 A - Peak pulse current supported at VC; used with PCB trace impedance to estimate let-through energy. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments with proper layout. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; informs thermal design margin. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Cathode/anode terminals are symmetrical; device functions identically in either orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient return path (bidirectional) | Completes low-impedance surge shunt path during both positive and negative overvoltage events. |
| Cathode | Transient return path (bidirectional) | Identical functional role to Anode; symmetry enables placement without orientation constraints. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control, ADAS, and body electronics. |
| 600 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 (4 kV line-earth) surge immunity when combined with appropriate series impedance. |
| Low clamping ratio (VC/VBR ≈ 1.34) | Minimizes overvoltage stress on protected ICs - critical for 3.3 V or 5 V logic interfaces with tight absolute maximum ratings. |
| MSL Level 1 moisture sensitivity | Enables standard SMT reflow without baking; reduces manufacturing cost and risk of popcorning. |
| Glass-passivated junction | Ensures long-term stability of leakage current and breakdown voltage across temperature and lifetime. |
Applications
| Automotive Sensor Interface Protection | Industrial PLC Digital I/O Protection |

IC Role / Device Role / Timing Role: Secondary-level TVS deployed after gas discharge tube (GDT) primary protection to handle residual fast-rising transients. Use Value: Sub-1 ns response time captures high-frequency components missed by slower GDTs, reducing bit error rate during surge events. |
Use Scenario: Suppressing inductive kickback from brushed DC motors in washing machines, HVAC blowers, and power tools. IC Role / Device Role / Timing Role: Across-motor terminals to clamp back-EMF spikes during MOSFET switching transitions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75CA | Same VWM (64.1 V), identical SMB package, but rated for 600 W with tighter VBR tolerance (±5 % vs ±10 % for P6SMB); not AEC-Q101 qualified. | Lacks automotive qualification; suitable for commercial/industrial use only. | Select SMBJ75CA if AEC-Q101 is not required and tighter breakdown tolerance improves system margin. |
| 1.5SMC75CA | Higher power rating (1500 W), larger SMC (DO-214AB) package, same VWM/VC specs; RoHS-compliant but not AEC-Q101 qualified. | Requires larger PCB footprint and higher thermal mass; better for high-energy surges where space allows. | Choose 1.5SMC75CA when surge threat level exceeds 600 W and board layout permits SMC package. |
Compared with SMBJ75CA and 1.5SMC75CA, the P6SMB75CAHE3/5B uniquely combines AEC-Q101 qualification, SMB footprint, and 600 W capability - making it the only drop-in solution for space-constrained automotive designs requiring certified reliability.

FAQ
What is the clamping voltage of the P6SMB75CAHE3/5B at its rated peak pulse current?
The P6SMB75CAHE3/5B has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current with a 10/1000 μs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB75CAHE3/5B maintains this clamping performance across its specified operating temperature range and after repeated surge exposures, provided thermal limits are respected.
Is the P6SMB75CAHE3/5B suitable for automotive applications?
Yes, the P6SMB75CAHE3/5B is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix and revision "B" qualification code. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 standards. The P6SMB75CAHE3/5B is commonly deployed in engine control units, ADAS camera modules, and body control modules where reliable transient suppression is mandated.
How does the bidirectional configuration of the P6SMB75CAHE3/5B affect its circuit implementation?
The bidirectional configuration of the P6SMB75CAHE3/5B means it provides symmetrical clamping for both positive and negative transients without polarity sensitivity - no cathode band marking is present, and orientation during placement is irrelevant. This simplifies layout for AC-coupled lines, differential buses like CAN or RS-485, and any application where voltage polarity reversal is possible. The P6SMB75CAHE3/5B delivers identical VBR, VC, and IPPM performance in either direction.
What is the thermal resistance of the P6SMB75CAHE3/5B, and how does it impact PCB layout?
The P6SMB75CAHE3/5B 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 maintain safe junction temperatures during repetitive surges, PCB layout must provide adequate copper area and avoid excessive trace length between the P6SMB75CAHE3/5B and ground/power planes. Reducing RθJA through enhanced copper pours directly extends surge endurance and reliability of the P6SMB75CAHE3/5B.
Does the P6SMB75CAHE3/5B meet RoHS and halogen-free requirements?
Yes, the P6SMB75CAHE3/5B is RoHS-compliant and carries the "HE3" suffix indicating AEC-Q101 qualification and RoHS compliance per EU Directive 2011/65/EU. It is not halogen-free - that designation applies only to "HM3" suffix variants. The P6SMB75CAHE3/5B uses matte tin-plated leads solderable per J-STD-002 and JESD 22-B102, and passes JESD 201 Class 2 whisker testing.
