Product details
Overview
TPSMA8.2HE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features 8.2 V nominal breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 33.1 V maximum clamping voltage (VC) at 200 A peak pulse current, 400 W peak pulse power (10/1000 μs), and operates up to +185 °C junction temperature - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the TPSMA8.2HE3_A/H datasheet, TPSMA8.2HE3_A/H pinout, TPSMA8.2HE3_A/H application, or TPSMA8.2HE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 10 mA test current for VBR, low 0.056 %/°C temperature coefficient, and compatibility with standard SMA PCB footprints for high-reliability board-level ESD and lightning surge protection.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and low incremental surge resistance. Its unidirectional architecture provides forward conduction only during overvoltage events, enabling precise clamping without reverse leakage degradation at elevated temperatures.
The device is rated for 400 W peak pulse power under 10/1000 μs waveform with 0.01 % duty cycle, and supports repetitive surge handling when mounted on 5.0 mm × 5.0 mm copper pads. It meets MSL Level 1 per J-STD-020 and passes JESD201 Class 2 whisker testing due to matte tin-plated terminals.
Key Specifications

FAQ
What is the breakdown voltage specification for TPSMA8.2HE3_A/H?
The TPSMA8.2HE3_A/H has a nominal breakdown voltage (VBR) of 8.20 V at 10 mA test current, with a guaranteed minimum of 7.79 V and maximum of 8.61 V. This parameter defines the voltage at which the device begins conducting significantly during a transient event, and is measured per ANSI/IEEE C62.35 standards using square-wave pulse conditions.
Is TPSMA8.2HE3_A/H qualified for automotive use?
Yes, TPSMA8.2HE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's official documentation and ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101 qualified construction. It supports automotive applications including engine control units, body electronics, and ADAS sensor interfaces requiring validated reliability under thermal and mechanical stress.
What does the "A/H" suffix mean in TPSMA8.2HE3_A/H?
The "A/H" suffix in TPSMA8.2HE3_A/H indicates the revision code ("A") and packaging configuration ("H" = 7-inch tape-and-reel, 1800 units per reel). This coding aligns with Vishay's ordering nomenclature in Document Number 88405 and ensures traceability to manufacturing lot, material composition, and qualification status for TPSMA8.2HE3_A/H.
How does TPSMA8.2HE3_A/H compare to bidirectional TVS diodes?
TPSMA8.2HE3_A/H is unidirectional, meaning it clamps only positive transients relative to ground and behaves like a forward-biased diode in reverse polarity. Unlike bidirectional variants, it provides lower leakage at VWM and avoids ambiguity in polarity-sensitive circuits - critical for protecting single-supply rails where reverse conduction must be avoided, such as in TPSMA8.2HE3_A/H-based 24 V industrial inputs.
What is the maximum clamping voltage of TPSMA8.2HE3_A/H during a surge event?
The maximum clamping voltage (VC) of TPSMA8.2HE3_A/H is 33.1 V at 200 A peak pulse current under the standardized 10/1000 μs waveform. This value represents the highest voltage imposed on the protected circuit during worst-case surge conditions and is measured with the device mounted on 5.0 mm × 5.0 mm copper pads per JEDEC guidelines for TPSMA8.2HE3_A/H.
