Product details
Overview
P6SMB11AHM3_B/H 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 9.4 V stand-off voltage (VWM), 10.5–11.6 V breakdown voltage (VBR) at 1 mA test current, 15.6 V maximum clamping voltage (VC) at 38.5 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - ideal for protecting MOSFETs and ICs in automotive and industrial power supplies.
For engineers reviewing the P6SMB11AHM3_B/H datasheet, P6SMB11AHM3_B/H pinout, P6SMB11AHM3_B/H application, or P6SMB11AHM3_B/H equivalent, this device delivers verified AEC-Q101 qualification, low incremental surge resistance, fast response time, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level ESD and surge protection design.
Technical Context
The P6SMB11AHM3_B/H operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its breakdown threshold to divert transient energy to ground. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<5 µA at VWM), while thermal resistance (RθJA = 100 °C/W) supports operation up to 150 °C junction temperature under defined PCB pad layout.
It is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine) and exhibits a positive temperature coefficient of VBR (+0.075 %/°C), enabling predictable voltage clamping across temperature. The device meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements, confirming suitability for automated SMT assembly and automotive-grade reliability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ11A-E3/5T | Same VWM (9.4 V), identical SMB package, but lower PPPM (400 W) and higher VC (18.2 V at 22 A). | Not AEC-Q101 qualified; suitable for commercial-grade consumer power rails only. | Select when cost is prioritized over automotive qualification and surge margin. |
| 1.5SMC11A | Same electrical specs (VWM, VBR, VC), but larger SMC (DO-214AB) package (2.54 mm height vs. SMB's 2.29 mm) and higher RθJA (120 °C/W). | Requires more PCB area and offers reduced thermal performance on same copper pad layout. | Choose only if legacy SMC footprint compatibility is mandatory and height constraint is relaxed. |
