Product details
Overview
TPSMP8.2HE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) in DO-220AA (SMP) package, with 7.38 V min / 9.02 V max breakdown voltage, 6.63 V standoff voltage, and 24.0 V clamping voltage at 200 A peak pulse current. It delivers 300 W peak pulse power for 10/1000 µs waveform and is AEC-Q101 qualified for engine control units and sensor protection.
For engineers reviewing the TPSMP8.2HE3/84A datasheet, TPSMP8.2HE3/84A pinout, TPSMP8.2HE3/84A application, or TPSMP8.2HE3/84A equivalent, key selection criteria include clamping performance under 200 A surge, low-profile 1.0 mm height for space-constrained PCB layouts, RoHS-compliant matte tin terminations, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This TVS diode uses patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and fast response time-critical for protecting sensitive automotive electronics against ISO 7637-2 load dump and ESD transients. Its unidirectional configuration enables precise reverse-biased clamping on DC power rails.
The device operates across -65 °C to +185 °C junction temperature range and maintains stable breakdown voltage with 0.065 %/°C temperature coefficient. Clamping occurs at 24.0 V under 200 A 10/1000 µs surge, with only 50 µA max reverse leakage at 6.63 V standoff voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 7.38 V min / 9.02 V max - defines minimum voltage at which clamping initiates reliably under 10 mA test current |
| Standoff Voltage VWM | 6.63 V - maximum continuous reverse working voltage before leakage exceeds 50 µA |
| Clamping Voltage VC | 24.0 V at 200 A - limits transient voltage seen by protected IC during worst-case surge event |
| Peak Pulse Power PPPM | 300 W (10/1000 µs) - sustains high-energy transients without failure when mounted on 5×5 mm copper pads |
| Junction Temp Range | -65 °C to +185 °C - supports under-hood automotive placement without derating |
| ESD Rating | IEC 61000-4-2 Level 4 compliant - withstands ±15 kV air / ±8 kV contact discharge |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including temperature cycling, HTRB, and UHAST |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Higher clamping voltage (27.7 V at 17.3 A), lower PPPM (400 W but rated at lower current), SMA package (2.5 mm height) | Less suitable for space-constrained automotive modules due to taller profile and reduced surge current handling (17.3 A vs. 200 A) | Select only if footprint compatibility with legacy SMA layout is mandatory and surge current demand is ≤17 A |
| TPSMA8.2A | Same breakdown range (7.79–8.61 V), identical AEC-Q101 qualification, but SMA package (2.5 mm height) and 17.8 A IPPM | Not interchangeable without PCB redesign; lacks the 200 A surge capability and low-profile advantage of TPSMP8.2HE3/84A | Choose only when existing SMA pad layout prevents DO-220AA adoption and 17.8 A surge rating suffices |
Compared with SMAJ8.0A and TPSMA8.2A, the TPSMP8.2HE3/84A provides 11× higher peak pulse current (200 A vs. ~17 A), 1.0 mm height for dense automotive layouts, and verified 300 W dissipation on standard FR-4-making it uniquely suited for next-generation compact ECU and ADAS modules requiring high surge resilience.

FAQ
What is the clamping voltage of the TPSMP8.2HE3/84A under maximum surge conditions?
The TPSMP8.2HE3/84A clamps to 24.0 V at 200 A peak pulse current with a 10/1000 µs waveform. This value is measured under standardized test conditions with 5.0 × 5.0 mm copper pads per terminal and represents the maximum voltage imposed on protected circuitry during worst-case transient events.
Is the TPSMP8.2HE3/84A suitable for under-hood automotive applications?
Yes, the TPSMP8.2HE3/84A is AEC-Q101 qualified and rated for junction temperatures from -65 °C to +185 °C. Its robust PAR oxide-passivated chip construction and 300 W peak pulse power rating make it appropriate for engine control units, transmission control modules, and other under-hood systems exposed to extreme thermal and electrical stress.
Does the TPSMP8.2HE3/84A have a bidirectional configuration?
No, the TPSMP8.2HE3/84A is unidirectional only. Its cathode is marked with a color band, and it functions as a reverse-biased avalanche diode-clamping transients on DC power rails where polarity is fixed. For AC or dual-polarity signal lines, a bidirectional variant like TPSMP8.2AHE3/84A would be required.
What is the standoff voltage rating for the TPSMP8.2HE3/84A?
The TPSMP8.2HE3/84A has a maximum standoff voltage (VWM) of 6.63 V. This is the highest continuous reverse voltage that can be applied without exceeding 50 µA leakage current at 25 °C, ensuring minimal power loss and no false triggering during normal operation.
How does the DO-220AA package of the TPSMP8.2HE3/84A compare to SMA in height and thermal performance?
The DO-220AA (SMP) package of the TPSMP8.2HE3/84A measures just 1.0 mm in height-less than half the 2.5 mm height of the SMA package-enabling tighter stacking and shield integration. Thermal resistance is optimized for FR-4 PCBs with 5×5 mm copper pads, delivering full 300 W pulse power without derating at 25 °C ambient.
