Product details
Overview
TPSMA13HE3_A/H 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 inductive switching surges.
For engineers reviewing the TPSMA13HE3_A/H datasheet, TPSMA13HE3_A/H pinout, TPSMA13HE3_A/H application, or TPSMA13HE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, low clamping ratio (VC/VBR = 1.40), and compatibility with automated SMT assembly per J-STD-002.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector triggered by reverse-biased avalanche breakdown. Its passivated anisotropic rectifier structure ensures stable leakage (<1.0 µA at VWM) and fast response (<1 ns), while the 185 °C maximum junction temperature supports under-hood automotive deployment without derating up to +125 °C ambient.
The device complies with IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) immunity requirements when applied with proper PCB layout-specifically using 5.0 mm × 5.0 mm copper pads per terminal-and delivers consistent clamping performance across its operating temperature range due to a +0.072 %/°C VBR temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 18.2 V - clamped voltage during 22.0 A surge, limiting downstream IC stress to safe levels |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 µs waveform, enabling robust surge immunity |
| TJ max. | +185 °C - enables operation in high-temperature environments such as engine control modules |

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 SMA package, 13 V VBR, but rated for 400 W with 1.0 W steady-state dissipation; no AEC-Q101 qualification | Not approved for automotive production; suitable for industrial/commercial designs without automotive qualification mandates | Select SMAJ13A when AEC-Q101 is not required and cost optimization is prioritized over automotive traceability |
| TPSMA13AHM3_A/H | Identical electrical specs and AEC-Q101 qualification; differs only in halogen-free molding compound (HM3 suffix vs. HE3) | Required where RoHS + halogen-free compliance is mandated (e.g., EU automotive Tier 1 supply chain) | Choose TPSMA13AHM3_A/H if halogen-free material content is specified in your BOM or regulatory documentation |
Compared with SMAJ13A and TPSMA13AHM3_A/H, the TPSMA13HE3_A/H provides identical surge performance and automotive qualification but uses standard RoHS-compliant (non-halogen-free) epoxy-making it optimal for cost-sensitive AEC-Q101 applications where halogen-free status is not enforced.

FAQ
What is the maximum clamping voltage of the TPSMA13HE3_A/H under a 10/1000 µs surge?
The TPSMA13HE3_A/H has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 22.0 A (10/1000 µs waveform). This value is measured per IEC 61000-4-5 test conditions and guarantees that downstream circuitry remains below critical voltage thresholds during transient events. The TPSMA13HE3_A/H maintains this clamping performance across its full operating temperature range.
Is the TPSMA13HE3_A/H qualified for automotive applications?
Yes, the TPSMA13HE3_A/H is AEC-Q101 qualified, meaning it has passed rigorous stress tests including high-temperature reverse bias, temperature cycling, and ESD immunity required for automotive electronic systems. Its 185 °C maximum junction temperature and MSL Level 1 rating further validate its suitability for under-hood and powertrain applications. The TPSMA13HE3_A/H is explicitly designated for automotive use in Vishay's ordering nomenclature.
What does the "HE3" suffix indicate in TPSMA13HE3_A/H?
"HE3" denotes Vishay's RoHS-compliant, AEC-Q101-qualified product variant with standard molding compound (not halogen-free). The "_A/H" indicates revision A in 7" tape-and-reel packaging (1800 units per reel). The HE3 suffix confirms compliance with JESD201 Class 2 whisker resistance and J-STD-002 solderability standards. This designation applies uniquely to the TPSMA13HE3_A/H and distinguishes it from HM3 (halogen-free) variants.
How does the TPSMA13HE3_A/H compare to bidirectional TVS diodes?
The TPSMA13HE3_A/H is unidirectional and protects only against reverse-polarity transients-ideal for DC power rails and single-ended signal lines referenced to ground. Unlike bidirectional TVS diodes, it offers lower leakage (<1.0 µA at 11.1 V) and tighter VBR tolerance, but cannot suppress positive-going transients on AC-coupled or floating lines. System designers must verify polarity alignment; incorrect installation renders the TPSMA13HE3_A/H ineffective.
What PCB layout guidelines apply to the TPSMA13HE3_A/H for optimal surge performance?
For rated 400 W surge handling, Vishay specifies mounting the TPSMA13HE3_A/H on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, with short, low-inductance traces to minimize voltage overshoot. Thermal vias under pads improve heat dissipation during repetitive surges. The TPSMA13HE3_A/H must be placed as close as possible to the protected port, with ground return path direct to system ground plane-not daisy-chained-to preserve clamping speed and effectiveness.
