Product details
Overview
TPSMA13AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, rated for 13.0 V breakdown voltage (VBR), 22.0 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs). It clamps transients to ≤18.2 V at IPPM and operates up to +185 °C junction temperature, protecting MOSFETs and ICs in automotive power supply rails.
For engineers reviewing the TPSMA13AHE3_A/I datasheet, TPSMA13AHE3_A/I pinout, TPSMA13AHE3_A/I application, or TPSMA13AHE3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, unidirectional polarity, 11.1 V stand-off voltage (VWM), <1.0 µA reverse leakage at VWM, and MSL Level 1 moisture sensitivity rating.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for high reliability under thermal stress. Its clamping behavior is defined by a 10/1000 µs waveform, with derating above 25 °C per Fig. 2 and validated operation from –65 °C to +185 °C junction temperature.
The device exhibits low incremental surge resistance and fast response time typical of silicon avalanche diodes, enabling effective suppression of inductive switching spikes and lightning-induced surges on DC power lines. Its cathode-band polarity marking and matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Suppressing load-dump transients (up to 35 V, 100 ms) on 12 V battery-fed ECUs in passenger vehicles. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between battery rail and input filter capacitor to clamp overvoltage before it reaches PMIC or MCU. Use Value: Limits peak voltage to ≤18.2 V during 22 A surge, preventing latch-up or gate oxide damage in downstream 16 V-rated regulators. | Use Scenario: Protecting analog front-end inputs of pressure/temperature sensors connected to 24 V industrial PLC I/O modules. IC Role / Device Role / Timing Role: Standoff protection element on sensor supply line, absorbing inductive kickback from solenoid drivers sharing same bus. Use Value: With 11.1 V VWM, it remains inactive during normal 24 V operation but activates within nanoseconds when transients exceed 12.4 V, preserving signal fidelity. |
| Consumer Power Adapter Input Stage | Telecom DC Power Distribution |
Use Scenario: Secondary-side overvoltage protection in universal-input AC/DC adapters powering USB-C PD devices. IC Role / Device Role / Timing Role: Clamping component across bulk capacitor output, guarding against transformer flyback overshoot and rectifier recovery spikes. Use Value: 400 W pulse rating sustains repeated 10/1000 µs events from line surges while maintaining <1 µA leakage at 11.1 V, minimizing no-load power loss. | Use Scenario: Surge protection on -48 V DC distribution boards in telecom central offices exposed to lightning-induced ground potential rise. IC Role / Device Role / Timing Role: Unidirectional shunt protector on feed line to remote radio units, oriented to clamp negative-going transients toward ground. Use Value: Cathode-to-line configuration enables robust clamping at 18.2 V while supporting continuous operation at -48 V system voltage with negligible leakage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Same SMA package, 13 V VBR, but rated for 400 W only at 10/1000 µs with 0.01 % duty cycle; not AEC-Q101 qualified | Lacks automotive qualification and 185 °C TJ rating; suitable for commercial-grade consumer or industrial use only | Select SMAJ13A where AEC-Q101 compliance and extended temperature operation are not required |
| TPSMA13AHM3_A/I | Identical electrical specs and AEC-Q101 qualification; differs only in halogen-free molding compound and whisker-tested terminations | No functional difference; used where RoHS + halogen-free compliance is mandated (e.g., EU automotive Tier 1 supply chains) | Choose TPSMA13AHM3_A/I when halogen-free material content is contractually required |
Compared with SMAJ13A, TPSMA13AHE3_A/I delivers verified automotive reliability and higher thermal margin; compared with TPSMA13AHM3_A/I, it offers identical protection performance with standard RoHS-compliant materials-making it optimal for cost-sensitive AEC-Q101 applications without halogen restrictions.

FAQ
What is the maximum clamping voltage of the TPSMA13AHE3_A/I under specified test conditions?
The TPSMA13AHE3_A/I has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated 22.0 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C with the device mounted on 5.0 mm × 5.0 mm copper pads per Vishay specification. The clamping voltage ensures downstream components see limited overvoltage stress during transient events. TPSMA13AHE3_A/I maintains this performance across its full operating temperature range.
Is the TPSMA13AHE3_A/I qualified for automotive applications?
Yes, the TPSMA13AHE3_A/I is AEC-Q101 qualified, confirming its suitability for automotive electronic systems. It meets stress test requirements including temperature cycling, high-temperature operating life, and mechanical shock. Its +185 °C maximum junction temperature and MSL Level 1 rating further support use in engine control units, body electronics, and ADAS modules. TPSMA13AHE3_A/I carries the HE3 suffix denoting RoHS-compliance and AEC-Q101 qualification per Vishay's ordering nomenclature.
What does the "HE3" suffix indicate in TPSMA13AHE3_A/I?
The "HE3" suffix in TPSMA13AHE3_A/I indicates RoHS-compliant construction and AEC-Q101 qualification. It distinguishes this variant from non-automotive versions (e.g., base TPSMA13A) and confirms compliance with JEDEC J-STD-020 moisture sensitivity level 1 and JESD 201 class 2 whisker resistance. The "A/I" denotes packaging in 13-inch tape-and-reel format (7500 units per reel). TPSMA13AHE3_A/I is fully traceable and intended for high-reliability production environments.
How does the TPSMA13AHE3_A/I compare to bidirectional TVS diodes in circuit protection?
The TPSMA13AHE3_A/I is unidirectional and designed for DC line protection where polarity is fixed-such as 12 V battery rails or regulated power supplies. Unlike bidirectional TVS diodes, it provides lower capacitance and tighter VBR tolerance in one direction but cannot suppress symmetrical AC transients. Its 11.1 V VWM allows safe operation on 12 V systems while clamping positive excursions above 12.4 V. TPSMA13AHE3_A/I is not interchangeable with bidirectional types without verifying circuit polarity and transient profile.
What is the recommended PCB layout for optimal thermal and electrical performance of TPSMA13AHE3_A/I?
Vishay specifies mounting TPSMA13AHE3_A/I on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads attached to each terminal to achieve rated 400 W pulse power and thermal dissipation. Minimum pad dimensions per outline drawing are 1.88 mm wide with 1.68 mm minimum length. Thermal vias under pads are recommended for high-duty-cycle applications. The cathode band must align with silkscreen polarity marking to prevent reverse installation. TPSMA13AHE3_A/I requires no additional heatsinking under standard derating curves.
