Product details
Overview
P6SMB8.2AHE3_B/I 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 7.79 V to 8.61 V breakdown voltage (VBR) at 10 mA, 7.02 V stand-off voltage (VWM), 12.1 V maximum clamping voltage (VC) at 49.6 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 P6SMB8.2AHE3_B/I datasheet, P6SMB8.2AHE3_B/I pinout, P6SMB8.2AHE3_B/I application, or P6SMB8.2AHE3_B/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–65 °C to +150 °C), and real-world protection use cases - all confirmed from Vishay's official P6SMB Series specification document (Rev. 09-Jan-2024, Doc. #88370).
Technical Context
The P6SMB8.2AHE3_B/I operates as a unidirectional avalanche diode, conducting only when reverse voltage exceeds its VBR threshold (7.79–8.61 V), then clamping transient energy to ≤12.1 V at 49.6 A. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<200 μA at VWM).
Designed for automated SMT assembly, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C), has matte tin-plated leads compliant with JESD 22-B102, and is qualified to AEC-Q101 for automotive applications - indicated by the "HE3" base suffix and "_B" revision code per Vishay's ordering table.

This tight tolerance ensures predictable clamping onset in 5 V and 12 V systems. The P6SMB8.2AHE3_B/I maintains this specification across its full operating temperature range and lifetime, supported by glass passivation and AEC-Q101 qualification.
Is P6SMB8.2AHE3_B/I AEC-Q101 qualified?
Yes, P6SMB8.2AHE3_B/I is AEC-Q101 qualified - confirmed by the "HE3" base suffix and "_B" revision code in its ordering designation, per Vishay's P6SMB Series documentation. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD (HBM/MM), making P6SMB8.2AHE3_B/I suitable for automotive powertrain, body electronics, and ADAS modules where reliability is mission-critical.
What is the maximum clamping voltage of P6SMB8.2AHE3_B/I and at what current?
The P6SMB8.2AHE3_B/I has a maximum clamping voltage (VC) of 12.1 V at 49.6 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB8.2AHE3_B/I achieves this low clamping ratio (VC/VBR ≈ 1.46) due to optimized silicon geometry and low incremental surge resistance, directly protecting 3.3 V and 5 V logic interfaces.
What package type does P6SMB8.2AHE3_B/I use and what are its key mechanical features?
P6SMB8.2AHE3_B/I uses the SMB (DO-214AA) surface-mount package: low-profile (max height 1.95 mm), UL 94 V-0 rated molding compound, and matte tin-plated leads compliant with J-STD-002 solderability standards. Its 0.2" × 0.2" copper pad layout recommendation ensures optimal thermal dissipation. The P6SMB8.2AHE3_B/I's SMB footprint enables high-density PCB layouts while maintaining 600 W surge capability - a key advantage over larger SMC alternatives.
How does the "_B/I" suffix in P6SMB8.2AHE3_B/I affect its specifications and packaging?
The "_B" suffix denotes AEC-Q101 qualification and applies to P6SMB6.8A through P6SMB220A variants; "/I" indicates 13" diameter plastic tape-and-reel packaging with 3200 units per reel. These suffixes do not alter electrical parameters - the P6SMB8.2AHE3_B/I retains identical VBR, VC, PPPM, and thermal specs as base P6SMB8.2AHE3.
