Product details
Overview
TPSMC36AHE3/9AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 36 V breakdown voltage (VBR = 34.2–37.8 V), 1500 W peak pulse power (10/1000 µs), 49.9 V clamping voltage at 30.1 A, and operates up to +185 °C junction temperature. It is used to protect MOSFETs, ICs, and sensor signal lines in automotive power systems.
For engineers reviewing the TPSMC36AHE3/9AT datasheet, TPSMC36AHE3/9AT pinout, TPSMC36AHE3/9AT application, or TPSMC36AHE3/9AT equivalent, key selection criteria include unidirectional polarity, SMC (DO-214AB) package compatibility, AEC-Q101 qualification, 30.8 V stand-off voltage, and low incremental surge resistance for robust ESD and load-dump immunity.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for high-temperature stability. Its 185 °C maximum junction temperature and MSL Level 1 rating support reflow soldering at 260 °C peak, meeting stringent automotive reliability requirements.
The device delivers precise clamping performance with 49.9 V max clamping voltage at 30.1 A IPPM and exhibits a +0.090 %/°C temperature coefficient of VBR, enabling predictable voltage threshold behavior across wide thermal operating ranges in engine control units and battery management systems.

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 | 600 W PPPM, SMA package, lower IPPM (24.6 A), same VBR range | Not AEC-Q101 qualified; limited to commercial/industrial use | Select when cost sensitivity outweighs automotive qualification and surge energy requirements |
| TPSMC36AHM3/9AT | Identical electrical specs; halogen-free molding compound instead of standard RoHS | Required for halogen-free compliance programs (e.g., EU WEEE, specific OEM specs) | Choose when material compliance mandates halogen-free construction without changing circuit design |
Compared with SMAJ36A and TPSMC36AHM3/9AT, the TPSMC36AHE3/9AT uniquely combines AEC-Q101 qualification, 1500 W surge capacity, and SMC package thermal mass-making it optimal for high-reliability automotive power line protection where both energy handling and qualification are mandatory.

FAQ
What is the breakdown voltage tolerance for TPSMC36AHE3/9AT?
The TPSMC36AHE3/9AT has a specified breakdown voltage range of 34.2 V (minimum) to 37.8 V (maximum) at 1 mA test current, with a nominal value of 36.0 V. This ±5% tolerance ensures consistent overvoltage triggering across production lots while maintaining compatibility with 30.8 V stand-off voltage requirements in 36 V nominal systems.
Is TPSMC36AHE3/9AT suitable for automotive applications?
Yes, TPSMC36AHE3/9AT is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature. Its HE3 suffix confirms automotive-grade qualification, and its 1500 W peak pulse power supports ISO 7637-2 load-dump protection in 12 V and 24 V vehicle networks-making TPSMC36AHE3/9AT appropriate for ECUs, body controllers, and ADAS power domains.
What package type does TPSMC36AHE3/9AT use?
TPSMC36AHE3/9AT uses the SMC (DO-214AB) surface-mount package, measuring 7.11 mm × 6.22 mm × 2.62 mm. It features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability rating-enabling high-power dissipation and compatibility with automated PCB assembly processes.
How does the clamping voltage of TPSMC36AHE3/9AT compare to its breakdown voltage?
TPSMC36AHE3/9AT clamps at 49.9 V when subjected to its rated 30.1 A peak pulse current (IPPM), which is approximately 39% above its nominal 36.0 V breakdown voltage. This controlled voltage overshoot ensures effective protection of downstream 48 V-tolerant interfaces while maintaining sufficient margin below absolute maximum ratings of protected ICs.
Does TPSMC36AHE3/9AT have a bidirectional configuration option?
No, TPSMC36AHE3/9AT is unidirectional only, as confirmed in the Vishay datasheet. The device conducts in forward bias (anode-to-cathode) and blocks in reverse until breakdown occurs. For bidirectional protection, Vishay offers separate part numbers such as TPSMC36CA; TPSMC36AHE3/9AT must be used with correct polarity orientation in the circuit.
