Product details
Overview
TPSMA36AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SMA (DO-214AC) package, with 36.0 V nominal breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 49.9 V maximum clamping voltage (VC) at 8.0 A peak pulse current, and 400 W peak pulse power rating per 10/1000 µs waveform - used to protect MOSFETs and sensor signal lines in automotive powertrain control modules.
For engineers reviewing the TPSMA36AHE3_B/H datasheet, TPSMA36AHE3_B/H pinout, TPSMA36AHE3_B/H application, or TPSMA36AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature capability, low incremental surge resistance, and RoHS-compliant matte tin-plated terminals solderable per J-STD-002.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and fast response to transients. Its junction passivation enables reliable operation up to TJ = 185 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
The device delivers 400 W peak pulse power under 10/1000 µs waveform with 0.01 % duty cycle, clamps at ≤49.9 V when subjected to 8.0 A IPPM, and exhibits ≤1.0 µA reverse leakage at VWM = 30.8 V and TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5A (Vishay) | Same VBR (36.0 V), but lower PPPM = 400 W (same rating), different package (SMA vs. DO-214AC identical), same AEC-Q101 qualification | No functional difference; identical electrical specs and qualification status; differs only in packaging code and reel size | Select TPSMA36AHE3_B/H for standard 7" tape-and-reel delivery with HE3 suffix indicating RoHS + AEC-Q101 compliance |
| 1.5SMC36A (ON Semiconductor) | Same VBR (36.0 V), same PPPM = 400 W, but SMC (DO-214AB) package - 2.5 mm wider body, higher thermal mass, not AEC-Q101 qualified | Not suitable for automotive applications requiring AEC-Q101; acceptable for industrial/commercial where qualification is not mandated | Choose TPSMA36AHE3_B/H when AEC-Q101 validation and 185 °C operation are required; use 1.5SMC36A only if footprint allows larger SMC and qualification is unnecessary |
Compared with SMAJ36A-E3/5A, TPSMA36AHE3_B/H offers identical protection performance and qualification but ships in H-coded 7" tape; versus 1.5SMC36A, it provides automotive-grade reliability, tighter thermal derating, and smaller SMA footprint - critical for space-constrained ECU designs.

FAQ
What is the exact breakdown voltage range for TPSMA36AHE3_B/H?
The TPSMA36AHE3_B/H has a guaranteed breakdown voltage (VBR) range of 34.2 V (min) to 37.8 V (max) at 1.0 mA test current, with 36.0 V as the nominal value. This range ensures consistent clamping behavior across production lots and supports design margining for automotive 12 V and 24 V systems where transient thresholds must be tightly controlled.
Is TPSMA36AHE3_B/H suitable for automotive applications?
Yes, TPSMA36AHE3_B/H is AEC-Q101 qualified and carries the HE3 suffix denoting RoHS compliance and automotive-grade reliability. It operates up to 185 °C junction temperature and meets MSL Level 1, making it suitable for under-hood engine control units, transmission control modules, and ADAS sensor interfaces where thermal and environmental stress is extreme.
What does the "HE3_B/H" suffix mean in TPSMA36AHE3_B/H?
The "HE3" suffix indicates RoHS-compliant construction and AEC-Q101 qualification; "B" denotes revision level; "H" specifies 7-inch plastic tape-and-reel packaging with 1800 units per reel. This full ordering code ensures traceability, compliance, and compatibility with automated SMT placement equipment used in high-volume automotive manufacturing.
How does TPSMA36AHE3_B/H compare to older TPSMA36A variants without HE3?
TPSMA36AHE3_B/H replaces legacy non-HE3 versions with verified AEC-Q101 qualification, enhanced process control for 185 °C operation, and RoHS compliance. Non-HE3 variants lack formal automotive qualification and may not meet the same thermal cycling or HTRB test requirements - TPSMA36AHE3_B/H is the designated part for new automotive designs requiring documented reliability.
What is the maximum clamping voltage of TPSMA36AHE3_B/H at rated surge current?
The maximum clamping voltage (VC) of TPSMA36AHE3_B/H is 49.9 V at 8.0 A peak pulse current (IPPM) under 10/1000 µs waveform. This value is measured with the device mounted on PCB using 0.2" × 0.2" copper pads per terminal, ensuring realistic system-level protection performance for downstream 36 V-rated components.
