Product details
Overview
TPSMP30A-E3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-220AA (SMP) package, designed for automotive-grade overvoltage protection with 30 V breakdown voltage (VBR min/max = 28.5–31.5 V), 41.4 V clamping voltage at 9.7 A peak pulse current, and 400 W peak pulse power rating. It protects signal lines and drive transistors in engine control units and ADAS sensors.
For engineers reviewing the TPSMP30A-E3/84A datasheet, TPSMP30A-E3/84A pinout, TPSMP30A-E3/84A application, or TPSMP30A-E3/84A equivalent, key selection criteria include its AEC-Q101 qualification, 1.0 mm profile, 185 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on automotive PCBs.
Technical Context
This device operates as a unidirectional avalanche diode with fast response time (<1 ns) and low clamping ratio (VC/VBR ≈ 1.38), enabling effective suppression of ISO 7637-2 and ISO 16750-2 transients. Its patented PAR oxide passivated chip construction ensures stable breakdown characteristics and high reliability under repeated surge stress.
The DO-220AA package delivers high power density (400 W) in a 2.67 mm × 1.27 mm footprint with matte tin-plated terminals compliant to J-STD-002B. Thermal performance is specified with 5.0 × 5.0 mm copper pads per terminal, supporting operation up to 185 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V - defines minimum and maximum voltage at which avalanche conduction begins under 1 mA test current |
| VC @ IPPM | 41.4 V at 9.7 A - clamping voltage during 10/1000 µs surge, limiting downstream IC voltage stress |
| PPPM | 400 W - peak pulse power handling capability for 10/1000 µs waveform, critical for automotive load dump immunity |
| IFSM | 40 A - non-repetitive forward surge current rating, supports robustness against inductive switching events |
| TJ max | +185 °C - maximum junction temperature enables under-hood deployment without derating in high-ambient environments |
| VWM | 25.6 V - maximum working voltage before leakage exceeds 1 µA, ensuring no false triggering during normal operation |
| Package | DO-220AA (SMP) - ultra-low-profile surface-mount package (1.0 mm height) optimized for space-constrained automotive modules |
Pinout & Package
DO-220AA (SMP) package: cathode-indicating band on one end; two-terminal unidirectional configuration with anode and cathode leads. Matte tin-plated terminals meet J-STD-002B solderability requirements.

|---|---|
Use Scenario: Protects 12 V supply rail of gasoline/diesel ECU against load dump and jump-start transients per ISO 16750-2. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between battery input and DC/DC converter input stage. Use Value: Clamps 120 V/100 ms load dump to ≤41.4 V, preventing damage to LDOs and microcontrollers while maintaining <1 µA leakage at 25.6 V. |
Use Scenario: Shields LVDS or analog video signal lines in surround-view cameras from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS placed at connector interface to absorb ±8 kV contact ESD per IEC 61000-4-2. Use Value: Sub-1 ns response time and 41.4 V clamping prevent pixel corruption and frame loss during transient coupling into coaxial or FAKRA interfaces. |
| Radar Module CAN FD Bus Protection | Electric Power Steering (EPS) Motor Driver Gate Protection |
Use Scenario: Safeguards CAN FD physical layer transceivers in 77 GHz radar modules against induced surges from nearby high-current switching. IC Role / Device Role / Timing Role: Unidirectional TVS connected between CAN_H/CAN_L and chassis ground to shunt common-mode transients. Use Value: 400 W peak power rating handles repetitive 10/1000 µs pulses from motor noise, while 25.6 V VWM avoids interference with 24 V CAN FD common-mode range. |
Use Scenario: Protects gate drivers and MOSFETs in EPS motor inverters from Miller-induced voltage spikes during high-dI/dt switching. IC Role / Device Role / Timing Role: TVS placed across gate-source terminals of high-side N-channel MOSFETs to clamp overshoot. Use Value: 185 °C max junction temperature allows direct mounting near power stages, and low incremental surge resistance minimizes energy dissipation during dv/dt 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 |
|---|---|---|---|
| SMAJ30A-E3/5A | Same VBR range (28.5–31.5 V) but lower PPPM (400 W vs. 300 W), SMA package (2.5 mm height), not AEC-Q101 qualified | Limited to industrial/commercial use; unsuitable for under-hood automotive due to MSL Level 1 only and no automotive qualification | Select when cost sensitivity outweighs automotive qualification and height constraints are relaxed |
| TPSMP30AHE3/84A | Identical electrical specs and DO-220AA package, but HE3 suffix denotes high-reliability grade with extended AEC-Q101 testing (including HTOL and ESD HBM ≥8 kV) | Required for mission-critical systems like brake-by-wire or airbag controllers where FIT rate and long-term parametric stability are mandated | Select when functional safety compliance (ISO 26262 ASIL-B/C) or >15-year field life is required |
Compared with SMAJ30A-E3/5A and TPSMP30AHE3/84A, the TPSMP30A-E3/84A offers optimal balance of automotive qualification, ultra-low profile, and 400 W surge capability-making it ideal for volume production of non-safety-critical ADAS and body electronics where cost and board space are constrained.

FAQ
What is the clamping voltage of the TPSMP30A-E3/84A at its rated peak pulse current?
The TPSMP30A-E3/84A has a maximum clamping voltage (VC) of 41.4 V at 9.7 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream components see limited overvoltage during surge events. The TPSMP30A-E3/84A maintains this clamping performance across its full operating temperature range.
Is the TPSMP30A-E3/84A qualified for automotive applications?
Yes, the TPSMP30A-E3/84A carries the E3 suffix indicating commercial-grade AEC-Q101 qualification. It meets all stress tests defined in the AEC-Q101 standard-including temperature cycling, highly accelerated stress test (HAST), and mechanical shock-making it suitable for non-safety-critical automotive modules such as body control units and infotainment power supplies. The TPSMP30A-E3/84A is not rated for ASIL-B or higher functional safety applications.
What is the standoff voltage (VWM) of the TPSMP30A-E3/84A and why does it matter?
The TPSMP30A-E3/84A has a maximum standoff voltage (VWM) of 25.6 V, meaning it remains in high-impedance state with <1 µA leakage up to that voltage. This ensures no interference with nominal 24 V automotive systems during normal operation while allowing sufficient margin below the 28.5 V minimum breakdown voltage. The VWM specification directly determines system reliability by preventing false triggering during voltage ripple or cold-cranking dips.
Does the TPSMP30A-E3/84A require special PCB layout considerations?
Yes-the TPSMP30A-E3/84A requires 5.0 × 5.0 mm copper pads attached to each terminal to achieve its rated 400 W peak pulse power. Short, wide traces must connect the device directly between protected line and ground plane with minimal loop area. Thermal relief should be avoided on pads, and adjacent components must maintain ≥0.5 mm clearance due to the DO-220AA's 1.0 mm height. These layout rules are essential to realize the full surge rating of the TPSMP30A-E3/84A.
How does the TPSMP30A-E3/84A differ from the TPSMP30AHE3/84A variant?
The TPSMP30AHE3/84A is the high-reliability version of the same device, featuring extended AEC-Q101 testing including HTOL (high-temperature operating life) and enhanced ESD ratings (HBM ≥8 kV). Electrically identical to the TPSMP30A-E3/84A, it targets safety-critical applications such as brake control or airbag systems. The TPSMP30A-E3/84A remains appropriate for volume automotive applications where full ASIL compliance is not required.
