Product details
Overview
P6SMB62AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 53.0 V standoff voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1 mA, 85.0 V maximum clamping voltage (VC) at 7.1 A peak pulse current (IPPM), and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB62AHE3/52 datasheet, P6SMB62AHE3/52 pinout, P6SMB62AHE3/52 application, or P6SMB62AHE3/52 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), polarity marking convention, and real-world protection use cases - all confirmed from Vishay's official P6SMB Series specification document (Rev. 09-Jan-2024, Doc. #88370).
Technical Context
This TVS diode operates as a unidirectional clamping device: reverse-biased during normal operation and avalanche-conducting when transient voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the SMB package supports automated placement and meets UL 94 V-0 flammability rating.
The device is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), operates from −65 °C to +150 °C junction temperature, and exhibits a positive temperature coefficient of VBR (+0.104 %/°C), enabling predictable voltage drift under thermal stress in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1 mA - Voltage at which avalanche conduction begins; tight tolerance enables precise overvoltage trip point selection. |
| VC (Clamping Voltage) | 85.0 V at IPPM = 7.1 A - Maximum voltage seen by protected circuit during 10/1000 μs transient; determines downstream component stress level. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capacity under standardized surge waveform; validates robustness against IEC 61000-4-5 Level 4 surges. |
| ID (Reverse Leakage) | <1.0 μA at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | +150 °C - Enables reliable operation in under-hood automotive and high-temperature industrial enclosures without derating. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads; informs heatsinking requirements for repetitive surge duty. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/52 | Same SMB package, 64 V VBR min (61.2–66.8 V), 87.1 V VC at 6.9 A; RθJA = 110 °C/W; commercial grade only (no AEC-Q101). | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated. | Select SMAJ64A-E3/52 if cost sensitivity outweighs automotive qualification and thermal margin allows higher RθJA. |
| 1.5SMC62A | Higher-power SMC package (same VBR/VC), 1500 W PPPM, RθJA = 60 °C/W; larger footprint (7.11 × 6.22 mm vs. SMB's 4.57 × 3.94 mm). | Better thermal performance and surge handling but requires PCB layout change; not drop-in compatible. | Choose 1.5SMC62A only when system-level surge testing exceeds 600 W or sustained thermal dissipation demands lower RθJA. |
Compared with SMAJ64A-E3/52 and 1.5SMC62A, P6SMB62AHE3/52 uniquely combines AEC-Q101 qualification, SMB footprint compactness, and verified 600 W surge capability - making it optimal for space-constrained automotive and industrial modules requiring production-grade reliability without board redesign.

FAQ
What is the clamping voltage of P6SMB62AHE3/52 and how does it protect downstream components?
The P6SMB62AHE3/52 has a maximum clamping voltage (VC) of 85.0 V at 7.1 A peak pulse current (IPPM) under a 10/1000 μs waveform. This means that during a transient event, the device limits the voltage seen by protected circuitry to no more than 85.0 V - well below typical absolute maximum ratings of 100 V for many power MOSFETs and interface ICs. By doing so, P6SMB62AHE3/52 prevents overvoltage stress, gate oxide rupture, and latch-up failure in sensitive downstream components.
Is P6SMB62AHE3/52 qualified for automotive applications?
Yes, P6SMB62AHE3/52 is AEC-Q101 qualified, as confirmed by its HE3 suffix and Vishay's documentation (P6SMB Series Rev. 09-Jan-2024, Doc. #88370). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD - validating its suitability for under-hood and cabin electronics such as body control modules, sensor interfaces, and infotainment power rails.
What is the standoff voltage (VWM) of P6SMB62AHE3/52 and why is it important?
The standoff voltage (VWM) of P6SMB62AHE3/52 is 53.0 V - the maximum continuous reverse voltage the device can block without entering avalanche conduction. This value establishes the design margin between normal operating voltage and clamping onset; for example, it safely protects a nominal 48 V system where transients may exceed 53 V. Selecting a VWM ≥10–15% above nominal rail voltage ensures reliable blocking during steady-state operation while preserving fast response during surges.
How does the SMB (DO-214AA) package of P6SMB62AHE3/52 impact PCB layout and thermal performance?
The SMB (DO-214AA) package of P6SMB62AHE3/52 measures 4.57 mm × 3.94 mm with 2.20 mm height, enabling high-density placement on compact PCBs. Its thermal resistance is RθJA = 100 °C/W when mounted on 0.2" × 0.2" copper pads - meaning a 600 W surge generates ~70 °C junction rise above ambient for short durations. Layout must follow Vishay's recommended pad dimensions (0.086" × 0.060") to ensure mechanical reliability and optimal heat dissipation for P6SMB62AHE3/52.
What is the reverse leakage current of P6SMB62AHE3/52 and how does it affect low-power circuits?
P6SMB62AHE3/52 exhibits ≤1.0 μA maximum reverse leakage current (ID) at its 53.0 V standoff voltage (VWM), measured at 25 °C. This ultra-low leakage ensures minimal power loss in always-on or battery-backed circuits - critical for maintaining sleep-mode current budgets in automotive ECUs and IoT sensor nodes. The leakage remains stable across temperature due to glass-passivated junction construction, preserving accuracy in precision analog monitoring paths protected by P6SMB62AHE3/52.
