Product details
Overview
TPSMP36AHE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 34.2 V to 37.8 V breakdown voltage (VBR), 49.9 V clamping voltage (VC) at 8.0 A peak pulse current, and 400 W peak pulse power rating for VBR ≥ 13 V. It provides robust ESD and surge protection for sensor signal lines in automotive ECUs.
For engineers reviewing the TPSMP36AHE3/84A datasheet, TPSMP36AHE3/84A pinout, TPSMP36AHE3/84A application, or TPSMP36AHE3/84A equivalent, key selection criteria include AEC-Q101 qualification, 1.0 mm profile height, 30.8 V stand-off voltage (VWM), 1.0 µA max reverse leakage at VWM, and DO-220AA mechanical compatibility with automated SMT placement.
Technical Context
This TVS diode uses patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ISO 7637-2 and IEC 61000-4-5 transients. Its unidirectional configuration supports DC-biased signal line protection without forward conduction during normal operation.
The device operates over -65 °C to +185 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102 solderability standards, and HE3 suffix confirms JESD201 Class 2 whisker resistance.

What package type does TPSMP36AHE3/84A use, and what are its dimensions?
TPSMP36AHE3/84A uses the DO-220AA (SMP) package: 1.0 mm typical height, 2.67 mm length, 1.88 mm width, with cathode identified by a color band. Its ultra-low profile supports high-density PCB layouts in space-limited automotive camera and radar assemblies.
What is the clamping voltage of TPSMP36AHE3/84A at its rated peak pulse current?
The TPSMP36AHE3/84A clamps to a maximum of 49.9 V at 8.0 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is critical for ensuring protected ICs-such as LIN transceivers or ADC front-ends-remain within their absolute maximum voltage ratings during surge events.
Does TPSMP36AHE3/84A meet RoHS and lead-free soldering requirements?
Yes, TPSMP36AHE3/84A is RoHS 2002/95/EC compliant and features matte tin-plated leads qualified to J-STD-002 and JESD22-B102. The HE3 suffix confirms compliance with JESD201 Class 2 whisker resistance, making it suitable for high-reliability automotive reflow processes up to 260 °C peak.
