Product details
Overview
TPSMA8.2AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in SMA (DO-214AC) package, rated for 8.2 V breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 33.1 V clamping voltage (VC) at 200 A peak pulse current, and 400 W peak pulse power with 10/1000 µs waveform - used to protect MOSFETs and signal lines in automotive sensor units against inductive switching transients.
For engineers reviewing the TPSMA8.2AHE3_A/I datasheet, TPSMA8.2AHE3_A/I pinout, TPSMA8.2AHE3_A/I application, or TPSMA8.2AHE3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C maximum junction temperature, low 50 µA reverse leakage at VWM, and compatibility with standard SMA PCB footprints.
Technical Context
This device operates as a unidirectional TVS diode, leveraging passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge conditions. Its 10/1000 µs waveform rating supports protection against lightning-induced surges and inductive load switching events in harsh environments.
The TPSMA8.2AHE3_A/I exhibits a positive temperature coefficient of VBR (0.056 %/°C), enabling predictable voltage drift over temperature, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak - confirming suitability for high-reliability automotive PCB assembly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A | 600 W PPPM, SMB (DO-214AA) package, 34.4 V VC @ 171 A | Higher power handling but larger footprint; requires PCB redesign | Select when higher surge margin is needed and board space allows SMB footprint |

FAQ
What is the exact breakdown voltage range for TPSMA8.2AHE3_A/I?
The TPSMA8.2AHE3_A/I has a guaranteed breakdown voltage (VBR) range of 7.79 V (minimum) to 8.61 V (maximum) at 10 mA test current, with a typical value of 8.20 V. This specification is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 23-Jan-2024 (Document Number: 88405). The TPSMA8.2AHE3_A/I maintains this tolerance across its qualified operating temperature range.
Is TPSMA8.2AHE3_A/I AEC-Q101 qualified?
Yes, the TPSMA8.2AHE3_A/I is AEC-Q101 qualified. The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified construction, as stated in the Vishay datasheet under "Mechanical Data" and "Ordering Information". This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, making the TPSMA8.2AHE3_A/I suitable for automotive powertrain and body electronics applications.
What is the clamping voltage of TPSMA8.2AHE3_A/I at its rated peak pulse current?
The TPSMA8.2AHE3_A/I clamps to a maximum of 33.1 V at its rated peak pulse current (IPPM) of 200 A, using the standardized 10/1000 µs double-exponential waveform. This value is specified in the "Electrical Characteristics" table of the Vishay datasheet and reflects worst-case behavior under surge conditions - critical for ensuring downstream components like microcontrollers or transceivers remain within absolute maximum ratings.
Does TPSMA8.2AHE3_A/I support lead-free reflow soldering?
Yes, the TPSMA8.2AHE3_A/I supports lead-free reflow soldering and is rated for MSL Level 1 per J-STD-020, with a maximum peak temperature of 260 °C. Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the device passes JESD 201 Class 2 whisker testing - confirming long-term interconnect reliability in high-volume SMT manufacturing.
What is the reverse leakage current of TPSMA8.2AHE3_A/I at its stand-off voltage?
The TPSMA8.2AHE3_A/I exhibits a maximum reverse leakage current (IR) of 50 µA at its stand-off voltage (VWM) of 7.02 V and ambient temperature of 25 °C. At elevated temperature (TJ = 150 °C), leakage remains ≤1000 µA - a value verified in the "Electrical Characteristics" table and essential for low-power always-on sensor circuits where standby current must be minimized.
