Product details
Overview
TPSMC13AHE3/9AT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection of sensitive electronics. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 18.2 V maximum clamping voltage at 82.4 A peak pulse current, and operates up to +185 °C junction temperature - deployed in automotive power line and sensor interface protection.
For engineers reviewing the TPSMC13AHE3/9AT datasheet, TPSMC13AHE3/9AT pinout, TPSMC13AHE3/9AT application, or TPSMC13AHE3/9AT equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating curves, clamping performance under surge, and RoHS-compliant packaging details essential for automotive-grade ESD/surge design validation.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under repetitive transients. Its unidirectional polarity enables forward-biased operation during overvoltage events on DC-biased lines, and its 10/1000 µs waveform rating reflects standardized IEC 61000-4-5 surge immunity testing conditions.
The device achieves 185 °C maximum junction temperature capability and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility. Its low incremental surge resistance and fast response time (<1 ns) ensure effective suppression of inductive switching spikes and lightning-induced surges on 12 V automotive supply rails and signal paths.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/5AT | Lower PPPM (400 W), SMA package (smaller thermal mass), VC = 21.5 V @ 19.9 A | Suitable for lower-energy consumer electronics; not AEC-Q101 qualified | Select when cost and board space are prioritized over automotive surge robustness |
| 1.5KE13A | Through-hole DO-201 package, same VBR/VC, but 1500 W rating requires larger PCB footprint and manual assembly | Used in industrial power supplies where automated SMT is not required | Choose only if legacy through-hole manufacturing infrastructure is fixed and thermal cycling demands are lower |
Compared with SMAJ13A-E3/5AT and 1.5KE13A, the TPSMC13AHE3/9AT uniquely combines AEC-Q101 qualification, SMC package thermal efficiency, and 1500 W surge capacity in a surface-mount form factor - making it the only option qualified for front-end protection in modern automotive ECUs without layout or reliability compromise.

FAQ
What is the clamping voltage of TPSMC13AHE3/9AT at its rated peak pulse current?
The TPSMC13AHE3/9AT has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current (IPPM) of 82.4 A under a 10/1000 µs waveform. This value is measured per Figure 1 in the official Vishay datasheet (Document Number: 88407) and ensures downstream 20 V-rated components remain within safe operating limits during surge events. The TPSMC13AHE3/9AT maintains this clamping performance across its full operating temperature range.
Is TPSMC13AHE3/9AT qualified for automotive applications?
Yes, the TPSMC13AHE3/9AT is AEC-Q101 qualified, as confirmed by its HE3 suffix and explicit listing in Vishay's automotive-grade ordering codes. It undergoes stress testing including high-temperature reverse bias (HTRB), temperature cycling, and surge lifetime validation per the AEC-Q101 standard. The TPSMC13AHE3/9AT is intended for use in engine control units, body control modules, and other automotive subsystems requiring certified reliability.
What does the "HE3" suffix indicate in TPSMC13AHE3/9AT?
The "HE3" suffix in TPSMC13AHE3/9AT denotes RoHS-compliant construction and AEC-Q101 qualification, per Vishay's ordering nomenclature. It also indicates compliance with JESD 201 Class 2 whisker resistance and MSL Level 1 moisture sensitivity. The "9AT" denotes tape-and-reel packaging with 7-inch reel and 850-unit quantity. The TPSMC13AHE3/9AT is not halogen-free - that variant uses the HM3 suffix instead.
How does TPSMC13AHE3/9AT compare to TPSMC13AHE3/BH?
The TPSMC13AHE3/9AT and TPSMC13AHE3/BH share identical electrical specifications and AEC-Q101 qualification, differing only in packaging configuration: "9AT" specifies a 7-inch reel with 850 units, while "BH" denotes the same reel size but with a different internal reel code per Vishay's logistics system. Both are functionally interchangeable in design and assembly. The TPSMC13AHE3/9AT is fully compatible with standard SMC pick-and-place equipment and reflow profiles.
What is the maximum operating temperature for TPSMC13AHE3/9AT?
The TPSMC13AHE3/9AT has a maximum junction temperature (TJ) of +185 °C, enabling operation in high-ambient environments such as engine compartments or under-hood ECUs. Its thermal performance is validated with 8.0 mm × 8.0 mm copper pads per terminal, and derating curves in the datasheet show >90 % of rated PPPM remains usable at 150 °C ambient. This makes the TPSMC13AHE3/9AT suitable for demanding automotive thermal profiles where other TVS diodes fail.
