Product details
Overview
TPSMP8.2AHE3/85A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for automotive-grade overvoltage protection of signal lines and ICs. 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 per 10/1000 µs waveform - used in engine control units and sensor interfaces.
For engineers reviewing the TPSMP8.2AHE3/85A datasheet, TPSMP8.2AHE3/85A pinout, TPSMP8.2AHE3/85A application, or TPSMP8.2AHE3/85A equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-220AA mechanical dimensions, clamping performance under surge conditions, and automotive-grade reliability data directly applicable to ECU, ADAS camera, and body control module designs.
Technical Context
This TVS diode employs patented PAR oxide passivated chip construction to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and load-dump transients in automotive electronics. Its unidirectional polarity (cathode band marked) supports DC-biased signal line protection without reverse conduction during normal operation.
The device operates across -65 °C to +185 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. It is RoHS-compliant, AEC-Q101 qualified, and rated for 40 A non-repetitive forward surge current (IFSM), making it suitable for under-hood applications requiring high thermal robustness.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V - ensures reliable triggering above system operating voltage while avoiding false clamping during nominal 7 V–8 V rail conditions |
| VWM | 7.02 V - maximum continuous reverse voltage before leakage exceeds 50 µA, compatible with 5 V–7 V logic and sensor supply rails |
| VC @ IPPM | 24.8 V at 200 A - limits transient voltage seen by protected ICs to safe levels during ISO 7637-2 Pulse 1/2a/5a events |

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 | Higher VBR (7.22–8.88 V), same DO-214AC package but 2.4 mm height vs. TPSMP8.2AHE3/85A's 1.0 mm; 200 W PPPM rating | Limited suitability for ultra-low-profile automotive modules; not AEC-Q101 qualified | Select SMAJ8.0A only for cost-sensitive industrial applications where height and automotive qualification are non-critical |
| SMCJ8.0A | Same VBR range (7.22–8.88 V), DO-214AB package (2.79 mm height), 1500 W PPPM, higher IPPM (123 A) | Better suited for high-energy surges (e.g., ISO 16750-2), but incompatible with tight Z-space constraints in modern ECUs | Choose SMCJ8.0A when surge energy exceeds 300 W and board layout allows larger footprint and height |
Compared with SMAJ8.0A and SMCJ8.0A, the TPSMP8.2AHE3/85A delivers AEC-Q101 qualification, 1.0 mm profile, and optimal 300 W/200 A balance for space-constrained automotive signal protection - whereas SMAJ8.0A lacks qualification and SMCJ8.0A sacrifices miniaturization for higher surge capacity.
