Product details
Overview
TPSMC13AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 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 clamping voltage at 82.4 A peak surge current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPSMC13AHE3_A/I datasheet, TPSMC13AHE3_A/I pinout, TPSMC13AHE3_A/I application, or TPSMC13AHE3_A/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, SMC package mechanical data, and real-world protection use cases for automotive, industrial, and telecom signal-line circuits.
Technical Context
The TPSMC13AHE3_A/I implements a passivated anisotropic rectifier structure optimized for fast response (<1 ns) and low incremental surge resistance, enabling precise clamping during ESD and lightning-induced transients. Its unidirectional polarity and cathode-band marking align with standard PCB layout conventions for reverse-biased protection placement across DC rails or signal lines.
Rated for TJ = –65 °C to +185 °C, it supports high-temperature environments without derating loss up to 125 °C ambient, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. The device is AEC-Q101 qualified (HE3 suffix), confirming suitability for automotive under-hood and infotainment applications requiring long-term reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - Ensures reliable turn-on before downstream IC damage threshold; tight 5.4% tolerance enables predictable protection margin. |
| VWM | 11.1 V - Maximum continuous working voltage; allows safe operation on 12 V nominal systems with ripple and tolerance margin. |
| VC @ IPPM | 18.2 V - Clamping voltage at 82.4 A surge; limits transient energy delivered to protected circuit within safe IC input range. |
| PPPM | 1500 W - Peak pulse power handling (10/1000 µs); sustains high-energy surges common in automotive load-dump and inductive switching events. |
| IR @ VWM | 2.0 µA - Reverse leakage at 11.1 V; negligible standby current draw critical for battery-powered sensor nodes. |
| TJ max. | +185 °C - Junction temperature rating; supports operation in engine control units, power converters, and industrial motor drives without thermal shutdown. |

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 | Lower peak pulse power (400 W), same SMC package, identical VBR range but higher VC (21.5 V @ 19.3 A). | Not AEC-Q101 qualified; suitable for commercial-grade consumer or office equipment only. | Select when cost sensitivity outweighs automotive qualification and surge energy requirements. |
| TPSMC13AHM3_A/I | Halogen-free variant with identical electrical specs, same AEC-Q101 qualification, and identical thermal performance. | Required for RoHS+halogen-free compliance mandates in EU automotive Tier 1 supply chains. | Choose when halogen-free material declaration is contractually required, otherwise TPSMC13AHE3_A/I remains optimal. |
Compared with SMAJ13A and TPSMC13AHM3_A/I, the TPSMC13AHE3_A/I uniquely balances 1500 W surge capability, AEC-Q101 qualification, and RoHS compliance in a single SMC package-making it the preferred choice for automotive and industrial designs demanding both robustness and regulatory alignment.

FAQ
What is the clamping voltage of the TPSMC13AHE3_A/I at its rated peak pulse current?
The TPSMC13AHE3_A/I 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 reflects the actual voltage seen by the protected circuit during worst-case surge conditions. The TPSMC13AHE3_A/I maintains this clamping performance across its full operating temperature range.
Is the TPSMC13AHE3_A/I qualified for automotive applications?
Yes, the TPSMC13AHE3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in the TPSMC6.8A–TPSMC47A datasheet (Rev. 19-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature operating life, and ESD robustness, making the TPSMC13AHE3_A/I suitable for under-hood and cabin automotive modules where reliability is mission-critical.
What does the "HE3" suffix mean in TPSMC13AHE3_A/I?
The "HE3" suffix in TPSMC13AHE3_A/I indicates RoHS-compliant construction and AEC-Q101 qualification per Vishay's standardized ordering nomenclature. It also denotes matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and passing JESD 201 Class 2 whisker testing. The "A/I" portion specifies the revision code "A" and tape-and-reel packaging in 13-inch reels (3500 units per reel).
What is the maximum operating temperature for the TPSMC13AHE3_A/I?
The TPSMC13AHE3_A/I has a maximum junction temperature (TJ) rating of +185 °C, with an operating junction and storage temperature range of –65 °C to +185 °C. This enables reliable operation in high-ambient environments such as engine compartments, industrial motor drives, and enclosed power supplies where thermal management is constrained. Derating curves in the datasheet confirm usable power capability up to 150 °C ambient.
How does the TPSMC13AHE3_A/I compare to the TPSMC13AHM3_A/I variant?
The TPSMC13AHE3_A/I and TPSMC13AHM3_A/I share identical electrical specifications, AEC-Q101 qualification, and thermal performance. The sole difference is that TPSMC13AHM3_A/I is halogen-free in addition to being RoHS-compliant, whereas TPSMC13AHE3_A/I is RoHS-compliant but not halogen-free. Both use the same SMC (DO-214AB) package and HE3/HM3 lead finish standards.
