Product details
Overview
TPSMP36HM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 32.4 V minimum breakdown voltage (VBR), 52.0 V maximum clamping voltage (VC) at 7.7 A peak pulse current, 400 W peak pulse power rating, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TPSMP36HM3/84A datasheet, TPSMP36HM3/84A pinout, TPSMP36HM3/84A application, or TPSMP36HM3/84A equivalent, key selection criteria include clamping performance under 10/1000 µs surges, unidirectional polarity for DC rail protection, TJ = 185 °C operation, MSL Level 1 solderability, and compatibility with automated SMT placement on FR-4 PCBs with 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD, lightning-induced transients, and load dump events. Its unidirectional configuration provides forward conduction path during overvoltage while maintaining low leakage (<1 µA at VWM = 29.1 V) in normal operation.
The device operates across -65 °C to +185 °C junction temperature range and is rated for 40 A non-repetitive peak forward surge current (IFSM). Its DO-220AA package delivers high power density with 1.0 mm typical height, meeting J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker resistance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | DO-214AC package (higher profile: 2.3 mm), 400 W PPPM, VC = 58.1 V @ 6.9 A | Less suitable for ultra-low-profile designs; lower thermal mass reduces surge endurance in repeated events | Select SMAJ36A only if board height >2.0 mm is acceptable and legacy DO-214AC footprint exists |
| SMCJ36A | DO-214AB package (larger footprint, 2.79 mm height), 1500 W PPPM, VC = 58.1 V @ 25.8 A | Higher surge capacity but incompatible footprint and thermal profile; requires larger PCB area | Choose SMCJ36A for higher-energy threats where space permits; not a drop-in replacement for TPSMP36HM3/84A |
Compared with SMAJ36A and SMCJ36A, TPSMP36HM3/84A offers superior power density (400 W in 1.0 mm height), AEC-Q101 qualification, and MSL Level 1 compatibility-making it optimal for next-generation automotive and space-constrained industrial modules where footprint, height, and automotive reliability are mandatory.

FAQ
What is the clamping voltage of TPSMP36HM3/84A under a 10/1000 µs surge?
The TPSMP36HM3/84A has a maximum clamping voltage (VC) of 52.0 V at 7.7 A peak pulse current with a 10/1000 µs waveform. This value is measured per Fig. 1 and Fig. 3 in Vishay document 88471 and represents the upper limit of voltage imposed on the protected circuit during standardized surge testing. The TPSMP36HM3/84A maintains this clamping performance across its full operating temperature range.
Is TPSMP36HM3/84A suitable for automotive applications?
Yes, TPSMP36HM3/84A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and chassis-mounted automotive electronics. Its DO-220AA package meets MSL Level 1, and its construction uses halogen-free, RoHS-compliant materials aligned with automotive supply chain requirements. The TPSMP36HM3/84A is explicitly listed in Vishay's automotive-grade product documentation.
What is the standoff voltage (VWM) of TPSMP36HM3/84A?
The standoff voltage (VWM) of TPSMP36HM3/84A is 29.1 V - the maximum DC or continuous reverse voltage that can be applied without exceeding the specified leakage current of 1.0 µA at 25 °C. This allows safe integration into 24 V automotive and industrial systems where nominal rail voltage remains below VWM during normal operation. The TPSMP36HM3/84A maintains this rating across its full temperature range.
Does TPSMP36HM3/84A have polarity marking, and how is it oriented on PCB?
Yes, TPSMP36HM3/84A uses a cathode band to indicate polarity. The banded end is the cathode and must be connected to the line being protected (e.g., 24 V rail), while the unmarked end is the anode and connects to system ground. Correct orientation is essential for unidirectional clamping function; reverse installation prevents surge conduction. The TPSMP36HM3/84A's polarity marking is visible under standard optical inspection and compatible with automated optical alignment systems.
What is the peak pulse power rating of TPSMP36HM3/84A, and at which VBR range does it apply?
The TPSMP36HM3/84A has a peak pulse power rating (PPPM) of 400 W, applicable to devices with breakdown voltage (VBR) between 13 V and 43 V - which includes the TPSMP36HM3/84A's VBR range of 32.4 V to 39.6 V. This rating is defined per 10/1000 µs waveform with derating above 25 °C ambient, per Fig. 2 in Vishay document 88471. The TPSMP36HM3/84A delivers this power density in a 1.0 mm profile package.
