Product details
Overview
TPSMA13AHE3/61T from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 22.0 A peak pulse current (IPPM), 18.2 V maximum clamping voltage (VC) at IPPM, and 400 W peak pulse power (10/1000 µs). It is used to protect MOSFETs and sensor signal lines in automotive ECUs against lightning-induced surges.
For engineers reviewing the TPSMA13AHE3/61T datasheet, TPSMA13AHE3/61T pinout, TPSMA13AHE3/61T application, or TPSMA13AHE3/61T equivalent, key selection criteria include unidirectional polarity, 185 °C junction temperature rating, AEC-Q101 qualification, low clamping ratio (VC/VBR = 1.40), and compatibility with automated SMT assembly per J-STD-002.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and surge robustness. Its unidirectional structure provides forward conduction only during reverse overvoltage events, enabling precise clamping without forward-path interference in DC-biased circuits.
The device operates across -65 °C to +185 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its 10/1000 µs waveform response delivers consistent 400 W pulse power dissipation under repetitive 0.01 % duty cycle conditions when mounted on 5.0 mm × 5.0 mm copper pads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Same VBR (13.0 V), but lower PPPM (400 W vs. 400 W), identical SMA package, no AEC-Q101 qualification | Not qualified for automotive use; suitable for industrial/commercial designs where AEC-Q101 is not mandated | Select SMAJ13A only if automotive qualification is unnecessary and cost optimization is prioritized |
| SMCJ13A | Same VBR and polarity, but larger SMC (DO-214AB) package, higher PPPM (1500 W), higher VC (21.5 V) | Requires PCB layout change; better suited for higher-energy surge environments like AC mains inputs | Choose SMCJ13A when surge energy exceeds 400 W capability and board space allows larger footprint |
Compared with SMAJ13A and SMCJ13A, the TPSMA13AHE3/61T uniquely combines AEC-Q101 qualification, 185 °C operation, and SMA footprint-making it optimal for space-constrained automotive modules requiring validated reliability without sacrificing surge margin.

FAQ
What is the maximum clamping voltage of the TPSMA13AHE3/61T at its rated peak pulse current?
The TPSMA13AHE3/61T has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated 22.0 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is measured per ANSI/IEEE C62.35 and ensures protected circuitry remains below critical overvoltage thresholds. The TPSMA13AHE3/61T maintains this clamping performance across its full operating temperature range.
Is the TPSMA13AHE3/61T qualified for automotive applications?
Yes, the TPSMA13AHE3/61T is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101 qualified construction. It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev G. The TPSMA13AHE3/61T is intended for use in automotive powertrain, body, and infotainment systems.
What is the stand-off voltage (VWM) of the TPSMA13AHE3/61T and why does it matter?
TPSMA13AHE3/61T has a stand-off voltage (VWM) of 11.1 V, meaning it remains non-conductive up to this reverse voltage at 25 °C and up to 1 μA leakage at 150 °C. This parameter ensures compatibility with 12 V nominal automotive systems, preventing false triggering during normal operation while allowing sufficient margin before breakdown at 13.0 V nominal VBR. The TPSMA13AHE3/61T uses this VWM/VBR relationship to balance protection sensitivity and system stability.
Does the TPSMA13AHE3/61T require special PCB layout considerations?
Yes - for optimal surge performance, the TPSMA13AHE3/61T must be mounted on PCB copper pads measuring 5.0 mm × 5.0 mm per terminal, as specified in Vishay Document 88405. Smaller pads reduce thermal mass and cause premature failure under repetitive surges. The TPSMA13AHE3/61T also requires short, low-inductance traces to ground to minimize clamping voltage overshoot during fast transients.
What is the junction temperature rating of the TPSMA13AHE3/61T and how does it impact design?
The TPSMA13AHE3/61T supports a maximum junction temperature (TJ) of +185 °C, enabling uninterrupted operation in high-ambient environments such as engine compartments or industrial enclosures. This eliminates thermal derating below 150 °C ambient and allows direct placement near heat sources. The TPSMA13AHE3/61T leverages this rating to maintain 400 W surge capability across its full temperature range without external heatsinking.
