Product details
Overview
TPSMP8.2AHM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 7.79 V to 8.61 V breakdown voltage (VBR), 7.02 V stand-off voltage (VWM), 24.8 V clamping voltage (VC) at 200 A peak pulse current, and 300 W peak pulse power rating under 10/1000 µs waveform - optimized for automotive sensor line and microcontroller I/O protection.
For engineers reviewing the TPSMP8.2AHM3/84A datasheet, TPSMP8.2AHM3/84A pinout, TPSMP8.2AHM3/84A application, or TPSMP8.2AHM3/84A equivalent, this device delivers AEC-Q101 qualification, 185 °C junction capability, ultra-low profile (1.0 mm height), MSL Level 1 reflow compatibility, and halogen-free RoHS-compliant construction - critical for automotive ECU, ADAS sensor interface, and industrial control board designs requiring robust surge immunity.
Technical Context
The TPSMP8.2AHM3/84A employs passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced transients, and load-dump events. Its unidirectional configuration provides forward conduction path during overvoltage while maintaining tight VWM/VBR ratio (7.02 V / 7.79–8.61 V) for reliable signal integrity in DC-biased lines.
Thermally, it supports continuous operation up to +185 °C junction temperature and dissipates 2.5 W on infinite heatsink at 75 °C ambient. The DO-220AA package enables automated placement and meets UL 94 V-0 flammability standard with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | DO-214AC package (higher profile: 2.3 mm), 8.0 V nominal VBR, 200 W PPPM, same 185 °C rating | Larger footprint and thermal mass; less suitable for ultra-thin automotive modules | Select when legacy DO-214AC layout exists and height constraint is relaxed |
| TPSMA6.8A | DO-214AC package, lower VBR (6.45–7.14 V), 250 W PPPM, identical AEC-Q101 qualification | Better suited for 5 V logic rails but insufficient clamping margin for 12 V automotive supply domains | Choose for 5 V microcontroller I/O protection where tighter VWM/VBR ratio is required |
Compared with SMAJ8.0A and TPSMA6.8A, the TPSMP8.2AHM3/84A offers superior power density (300 W in 1.0 mm height), tighter VBR tolerance (±5 %), and smaller DO-220AA footprint - making it optimal for next-generation automotive sensor nodes where board area and thermal envelope are constrained.
