Product details
Overview
P6SMB62A from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 62V, clamping voltage of 85V at 7.4A peak pulse current, and stand-off voltage of 53V. It features glass-passivated junction, low leakage (<1μA at 53V), and sub-1ps response time, deployed for overvoltage protection in DC power rails of switching mode power supplies.
For engineers reviewing the P6SMB62A datasheet, P6SMB62A pinout, P6SMB62A application, or P6SMB62A equivalent, key selection criteria include its DO-214AA (SMB) package compatibility, 600W peak pulse power rating per 10/1000μs waveform, unidirectional polarity marking, and compliance with ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive electronics surge immunity.
Technical Context
The P6SMB62A operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 58.9–65.1V breakdown range (tested at 1mA). Its clamping action limits transient-induced voltage to ≤85V under 7.4A 10/1000μs pulses, enabling robust protection of downstream ICs without crowbar behavior.
Thermally, it sustains junction temperatures from –55°C to +150°C, with RθJC = 10°C/W and RθJA = 55°C/W. Its matte tin-plated leads meet J-STD-002 solderability, and moisture sensitivity level is J-STD-020 Level 1 - suitable for standard reflow without baking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9V / 65.1V - defines reliable avalanche initiation window at 1mA test current |
| VWM | 53.0V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 85.0V at 7.4A - peak clamped voltage during 10/1000μs transient, determines protected circuit stress |
| PPPSM | 600W - non-repetitive surge power handling per standardized waveform, critical for automotive load dump |
| IR @ VWM | <1μA - ultra-low reverse leakage ensures minimal standby power loss in always-on systems |
| TJ max | +150°C - enables operation in high-temperature environments such as engine control units or enclosed power adapters |
| Package | DO-214AA (SMB) - industry-standard surface-mount outline with 0.090g mass and UL 94V-0 molding compound |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A (Bourns) | 64V VBR min/max = 60.8–67.2V; same 600W rating, identical DO-214AA package | Marginally higher VBR increases stand-off margin but raises clamping voltage to 93.6V | Select when tighter VBR tolerance (±5%) or extended AEC-Q200 qualification is required |
| 1.5SMC62A (ON Semiconductor) | Same VBR (58.9–65.1V) and VC (85V), but in larger DO-214AB (SMC) package (2.5mm height vs. SMB's 2.2mm) | Higher thermal mass improves repetitive surge handling but requires more PCB area | Choose when board space permits and higher IFSM (200A vs. 100A) is needed for infrequent high-energy events |
Compared with SMBJ64A and 1.5SMC62A, the P6SMB62A offers optimal balance of compact SMB footprint, precise 62V clamping, and ISO 7637-2 compliance - making it preferred for space-constrained automotive and industrial power interfaces where consistent 85V clamping is critical for 100V-rated downstream components.

FAQ
What is the polarity configuration of the P6SMB62A?
The P6SMB62A is a unidirectional TVS diode, with cathode indicated by a band on the DO-214AA (SMB) package body. It conducts only during reverse overvoltage events and blocks forward current like a standard rectifier. This configuration is confirmed in the device marking code MMJ and electrical specifications table, which lists VF = 3.5V at 50A - a parameter defined exclusively for unidirectional types in the datasheet.
Does the P6SMB62A meet automotive surge immunity standards?
Yes, the P6SMB62A meets ISO 7637-2 requirements for Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnection/interruption), and Pulse 3a/3b (capacitive coupling and switching noise). This compliance is explicitly stated in the FEATURES section and validated by its 600W 10/1000μs pulse rating and clamping performance - making the P6SMB62A suitable for use in automotive body control modules and infotainment power supplies.
What is the maximum clamping voltage of the P6SMB62A under surge conditions?
The maximum clamping voltage of the P6SMB62A is 85.0V at 7.4A peak pulse current (IPPM) under the standardized 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and appears in the ELECTRICAL SPECIFICATIONS table for the P6SMB62A row. It defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring compatibility with 100V-rated MOSFETs and controllers.
Is the P6SMB62A RoHS and halogen-free compliant?
Yes, the P6SMB62A is RoHS compliant per EU Directive 2011/65/EU and halogen-free according to IEC 61249-2-21. These environmental qualifications are explicitly listed in the FEATURES section and confirmed in the ordering information and mechanical data pages. The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin-plated to satisfy J-STD-002 solderability requirements - all verified for the P6SMB62A variant.
What is the thermal resistance profile of the P6SMB62A?
The P6SMB62A has a junction-to-case thermal resistance (RθJC) of 10°C/W and junction-to-ambient thermal resistance (RθJA) of 55°C/W, as specified in the THERMAL PERFORMANCE section. These values enable accurate thermal modeling in PCB layouts with standard copper pour and define safe power derating above 25°C ambient - essential for designing reliable protection in enclosed power adapters or under-hood automotive modules using the P6SMB62A.
