Product details
Overview
TPSMA13HE3/5AT 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 ICs in automotive power supply rails against lightning-induced surges and inductive switching transients.
For engineers reviewing the TPSMA13HE3/5AT datasheet, TPSMA13HE3/5AT pinout, TPSMA13HE3/5AT application, or TPSMA13HE3/5AT equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, clamping performance under surge conditions, and RoHS-compliant packaging details - all specific to the TPSMA13HE3/5AT variant with HE3 suffix and 5A tape-and-reel delivery mode.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability up to 185 °C junction temperature and meets AEC-Q101 stress test requirements for automotive use. Its unidirectional polarity enables protection of DC-biased lines without reverse conduction during normal operation.
The device delivers 400 W peak pulse power with a 10/1000 µs waveform at 0.01 % duty cycle and exhibits low incremental surge resistance, enabling fast response (<1 ns) and tight clamping across its operating temperature range. It is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine) and maintains stable VBR with a +0.072 %/°C temperature coefficient.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Same VBR (13.0 V), but SMB package (DO-214AA); 600 W PPPM; higher IPPM (33.0 A) | Larger footprint (0.236" x 0.157") limits use in space-constrained PCBs; better suited for higher-energy surge environments | Select SMBJ13A only if board layout allows larger package and system requires >400 W surge margin |
| TPSMA13AHM3/5AT | Identical electrical specs and SMA package; HM3 suffix denotes halogen-free construction (vs. HE3's RoHS-only) | No functional difference; HM3 required where halogen-free compliance is mandated (e.g., certain EU industrial standards) | Choose TPSMA13AHM3/5AT when halogen-free materials are specified in BOM; otherwise TPSMA13HE3/5AT satisfies standard automotive and industrial requirements |
Compared with SMBJ13A and TPSMA13AHM3/5AT, the TPSMA13HE3/5AT offers optimal balance of compact SMA footprint, AEC-Q101 qualification, 400 W surge capability, and cost-effective RoHS compliance - making it ideal for high-volume automotive body control modules and industrial IoT edge nodes where space and qualification are primary constraints.

FAQ
What is the maximum clamping voltage of the TPSMA13HE3/5AT at its rated peak pulse current?
The TPSMA13HE3/5AT has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated 22.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures predictable overvoltage limiting for downstream components such as automotive MCUs or industrial interface ICs. The TPSMA13HE3/5AT maintains this clamping performance across its full operating temperature range.
Is the TPSMA13HE3/5AT qualified for automotive applications?
Yes, the TPSMA13HE3/5AT carries the HE3 suffix, which indicates full AEC-Q101 qualification per Vishay's documentation (Document Number 88405, Revision 23-Jan-2024). It has passed stress tests including high-temperature reverse bias, temperature cycling, and humidity testing required for under-hood and cabin-mounted automotive electronics. The TPSMA13HE3/5AT is approved for use in engine control modules, body controllers, and ADAS sensor power supplies.
What does the "5AT" suffix indicate in TPSMA13HE3/5AT?
The "5AT" suffix in TPSMA13HE3/5AT specifies the packaging configuration: 7" diameter plastic tape-and-reel with 1800 units per reel (package code H), compliant with EIA-481-D standards. This differs from "5AI", which denotes 13" reel with 7500 units. The "5AT" format is optimized for high-speed SMT placement in medium-volume automotive and industrial production lines using TPSMA13HE3/5AT.
How does the TPSMA13HE3/5AT compare to bidirectional TVS diodes in surge protection design?
The TPSMA13HE3/5AT is unidirectional and intended for DC-biased lines where reverse conduction must be avoided during normal operation - unlike bidirectional TVS diodes that conduct in both polarities. Its 11.1 V stand-off voltage allows direct placement on 12 V systems without risk of forward conduction. For AC or floating signal lines, a bidirectional variant would be required; the TPSMA13HE3/5AT is not suitable for those topologies.
What is the thermal derating behavior of the TPSMA13HE3/5AT above 25 °C ambient?
The TPSMA13HE3/5AT follows standard derating curves per Figure 2 in Vishay Document 88405: its peak pulse power (400 W) and peak pulse current (22.0 A) decrease linearly above 25 °C ambient, reaching ~50 % of rated value at 125 °C case temperature. This behavior is directly tied to junction temperature limits (TJ ≤ 185 °C) and must be accounted for in thermally constrained layouts. The TPSMA13HE3/5AT's 185 °C max rating supports sustained operation in high-ambient environments when properly mounted.
