Product details
Overview
P6SMB75CA-E3/52 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). 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-E3/52 datasheet, P6SMB75CA-E3/52 pinout, P6SMB75CA-E3/52 application, or P6SMB75CA-E3/52 equivalent, this device delivers verified bidirectional clamping performance, AEC-Q101 qualification readiness (via HE3/HM3 variants), low thermal resistance (RθJL = 20 °C/W), and RoHS-compliant matte tin terminations suitable for automated SMT assembly.
Technical Context
The P6SMB75CA-E3/52 operates as a symmetric bidirectional TVS, with identical breakdown (VBR min/max = 71.3 V / 78.8 V at 1 mA) and clamping behavior in both polarities. Its glass-passivated junction ensures stable leakage (<1 μA at VWM) and fast response time (<1 ns) to transient events.
Designed for surface-mount reliability, it meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and achieves 150 °C maximum junction temperature. Thermal resistance from junction-to-lead (RθJL = 20 °C/W) enables effective heat dissipation on standard 0.2" × 0.2" copper pads without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 64.1 V - Maximum continuous reverse voltage before significant conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 71.3 V to 78.8 V at 1 mA - Voltage at which device enters avalanche; tight tolerance ensures predictable turn-on across production lots. |
| VC (Clamping Voltage) | 103 V at IPPM = 5.8 A - Peak voltage seen by protected circuit during 10/1000 μs surge; critical for IC-level overvoltage immunity. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy handling capability under standardized 10/1000 μs waveform at 0.01% duty cycle. |
| ID (Reverse Leakage) | <1 μA at VWM - Minimal standby current draw; preserves signal integrity and battery life in always-on circuits. |
| TJ max. | +150 °C - Enables operation in under-hood automotive and high-temperature industrial environments without derating. |
| RθJL | 20 °C/W - Low junction-to-lead thermal resistance allows efficient heat transfer to PCB copper, supporting sustained surge robustness. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking; case dimensions 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | One terminal of symmetrical avalanche junction; conducts during negative transients relative to cathode reference. |
| Cathode | Transient current entry (positive polarity) | Other terminal of symmetrical avalanche junction; conducts during positive transients; no band marking for bidirectional types. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions enables single-device protection of AC-coupled or floating signal lines without polarity concerns. |
| 600 W peak pulse power | Handles high-energy transients (e.g., ISO 7637-2 Pulse 1/2a/5a) common in 12 V/24 V automotive and industrial power systems. |
| MSL Level 1 rating | Supports unlimited floor life and standard reflow profiles up to 260 °C, eliminating moisture sensitivity handling requirements. |
| Glass passivated junction | Ensures long-term stability of breakdown voltage and leakage current under thermal cycling and humidity stress. |
| AEC-Q101 qualification path | HE3/HM3 variants are qualified for automotive applications; P6SMB75CA-E3/52 shares identical die and construction for drop-in qualification readiness. |

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 (64.1 V) and VC (103 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy transients; less suitable for automotive load dump where 600 W margin is required. | Select when board space is constrained and surge energy is limited to IEC 61000-4-5 Level 3 (0.5 J). |
| SMCJ75CA | Same VWM and VC, but higher PPPM (1500 W); larger SMC (DO-214AB) package with RθJL = 15 °C/W. | Over-specified for cost-sensitive consumer designs; requires larger PCB area and higher assembly cost. | Choose when protecting high-power industrial motor drives subject to repetitive 1500 W surges. |
Compared with SMAJ75CA and SMCJ75CA, the P6SMB75CA-E3/52 provides optimal balance of 600 W surge capacity, SMB footprint compatibility, and thermal performance (RθJL = 20 °C/W), making it ideal for space-constrained yet robust automotive and industrial applications requiring AEC-Q101 qualification path.

FAQ
What is the clamping voltage of the P6SMB75CA-E3/52 under a 10/1000 μs surge?
The P6SMB75CA-E3/52 has a maximum clamping voltage (VC) of 103 V at 5.8 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and represents the upper voltage limit imposed on protected circuitry during surge events, ensuring downstream ICs remain within safe operating limits.
Is the P6SMB75CA-E3/52 suitable for automotive applications?
Yes - the P6SMB75CA-E3/52 uses the same die and construction as AEC-Q101-qualified variants (e.g., P6SMB75CAHE3_B), shares MSL Level 1 reflow compatibility, and operates from −65 °C to +150 °C. While the E3/52 suffix denotes commercial grade, its design basis and thermal performance make it suitable for automotive use pending customer qualification.
How does the bidirectional nature of the P6SMB75CA-E3/52 affect its PCB layout?
The P6SMB75CA-E3/52 has no polarity marking and identical electrical behavior in both directions, simplifying PCB layout by eliminating orientation constraints. It can be placed across any two nodes requiring symmetric overvoltage protection - such as differential signal pairs or AC-coupled lines - without concern for anode/cathode alignment during automated placement.
What is the maximum reverse leakage current for the P6SMB75CA-E3/52 at its stand-off voltage?
The P6SMB75CA-E3/52 exhibits a maximum reverse leakage current (ID) of 1 μA at its rated stand-off voltage (VWM) of 64.1 V, measured at TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes power loss in battery-powered systems.
Does the P6SMB75CA-E3/52 require heatsinking for 600 W surge handling?
No - the P6SMB75CA-E3/52 achieves its 600 W peak pulse power rating with standard 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay document 88370. Its low junction-to-lead thermal resistance (RθJL = 20 °C/W) enables sufficient heat dissipation during short-duration transients without additional heatsinking.
