Product details
Overview
TPSMP12AHE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) in DO-220AA (SMP) package, featuring 11.4 V to 12.6 V breakdown voltage (VBR), 18.0 A peak pulse current (IPPM), and 16.7 V clamping voltage (VC) at IPPM, designed for robust ESD and surge protection of automotive sensor signal lines.
For engineers reviewing the TPSMP12AHE3/84A datasheet, TPSMP12AHE3/84A pinout, TPSMP12AHE3/84A application, or TPSMP12AHE3/84A equivalent, key selection criteria include AEC-Q101 qualification, 1.0 mm profile for space-constrained PCB layouts, low incremental surge resistance, and verified clamping performance under 10/1000 µs transients in automotive environments.
Technical Context
The TPSMP12AHE3/84A employs patented PAR oxide-passivated chip construction to achieve stable breakdown characteristics and low dynamic impedance. Its unidirectional configuration supports cathode-grounded protection topologies with fast response time (<1 ns) and minimal capacitance (typ. 150 pF at 0 V).
Rated for operation from –65 °C to +185 °C junction temperature, it delivers 300 W peak pulse power (10/1000 µs waveform) and withstands 40 A non-repetitive forward surge current (10 ms half-sine), meeting MSL Level 1 reflow compatibility up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 11.4 V min / 12.6 V max at 1 mA - defines precise overvoltage triggering threshold for reliable circuit protection |
| Clamping Voltage VC | 16.7 V at 18.0 A - limits downstream voltage stress during 10/1000 µs surge events |
| Peak Pulse Power PPPM | 300 W (10/1000 µs) - sustains high-energy transients without failure in automotive load-dump or ISO 7637-2 scenarios |
| Stand-off Voltage VWM | 10.2 V - ensures no conduction during normal 12 V system operation, minimizing leakage impact |
| Reverse Leakage IR | 1.0 µA at VWM, 25 °C - negligible standby current for battery-sensitive applications |
| Junction Temperature Range | –65 °C to +185 °C - enables deployment in under-hood automotive locations with extreme thermal cycling |

| Body Control Module (BCM) Inputs | ADAS Camera Power Rail |
Use Scenario: Guarding discrete switch inputs (e.g., door lock, window switch) against inductive kickback and battery reversal transients. IC Role / Device Role / Timing Role: Unidirectional TVS connected anode-to-line, cathode-to-ground on each input to absorb 300 W pulses without latch-up. Use Value: Withstands 40 A IFSM and operates up to +185 °C, enabling direct placement near high-temperature BCM power stages. |
Use Scenario: Protecting 12 V camera module power input from ISO 7637-2 pulse 5a (load dump) and pulse 1 (inductive switching). IC Role / Device Role / Timing Role: Primary front-end TVS on power rail, sized to handle 300 W peak pulse energy while maintaining low thermal resistance. Use Value: Achieves 300 W rating in 1.0 mm height package, allowing integration into narrow camera PCBs without heatsink or layout compromise. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A-E3/5AT | DO-214AC (SMA) package; 12.2 V to 13.5 V VBR; 200 W PPPM; higher 1.9 mm profile | Larger footprint and lower power rating limit suitability for space-constrained automotive modules | Select when legacy SMA footprint compatibility is required and 300 W rating is not critical |
| TPSMA6.8A-S | DO-214AC package; 6.8 V VBR; 400 W PPPM but lower voltage rating; same AEC-Q101 grade | Not suitable for 12 V systems due to 6.8 V VBR; intended for 5 V logic rail protection | Choose only for 5 V interface protection where lower clamping voltage is needed |
Compared with SMAJ12A-E3/5AT and TPSMA6.8A-S, the TPSMP12AHE3/84A uniquely combines AEC-Q101 qualification, 300 W pulse rating, and 1.0 mm height in DO-220AA-making it optimal for next-generation compact automotive electronics where thermal density and board area are constrained.
