Product details
Overview
TPSMC13A-2HE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge clamping with 1500 W peak pulse power (10/1000 μs), 13.0 V nominal breakdown voltage, and 18.2 V maximum clamping voltage at 82.4 A IPPM. It operates from −65 °C to +185 °C and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the TPSMC13A-2HE3_B/I datasheet, TPSMC13A-2HE3_B/I pinout, TPSMC13A-2HE3_B/I application, or TPSMC13A-2HE3_B/I equivalent, key selection criteria include clamping voltage vs. surge current, unidirectional polarity, junction temperature derating above 25 °C, and RoHS-compliant, halogen-free HE3 suffix qualification status.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable breakdown behavior up to TJ = 185 °C, enabling use in under-hood automotive environments. Its low incremental surge resistance and fast response time ensure effective suppression of transients induced by inductive load switching or ESD events on signal/power lines.
The device is rated for 200 A non-repetitive forward surge current (8.3 ms half-sine), exhibits 11.1 V stand-off voltage, and maintains ≤2.0 μA reverse leakage at VWM - critical for low-power sensor interface protection where standby current integrity matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 / 13.0 / 13.7 V - ensures reliable triggering above system operating voltage while avoiding false trips |
| VWM | 11.1 V - defines maximum continuous reverse working voltage before leakage rises significantly |
| VC @ IPPM | 18.2 V - clamping voltage at 82.4 A peak pulse current; determines protected IC's maximum stress during surge |
| PPPM | 1500 W - peak pulse power handling capability with 10/1000 μs waveform, supporting robust industrial transients |
| TJ max. | +185 °C - enables operation in high-temperature automotive and industrial enclosures without thermal derating loss |
| Polarity | Unidirectional - protects against positive-going transients only; requires correct cathode orientation in PCB layout |
| Package | SMC (DO-214AB) - standardized surface-mount outline with 8.0 mm × 8.0 mm copper pad requirement for thermal dissipation |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Lower PPPM (400 W), same VBR range, SMA package (smaller thermal mass) | Not rated for AEC-Q101; limited to consumer/industrial use below 150 °C ambient | Select when cost and board space are prioritized over automotive qualification and high-energy surge handling |
| TPSMC13CA | Bi-directional variant; identical VBR, VC, and PPPM but supports ±13 V clamping | Required for AC-coupled or bidirectional signal lines (e.g., RS-232, audio), not suitable for DC power rail protection | Choose only when protecting symmetrical signals or lines subject to both polarities of transients |
Compared with SMAJ13A and TPSMC13CA, the TPSMC13A-2HE3_B/I delivers higher energy absorption (1500 W vs. 400 W) and automotive-grade reliability, making it optimal for safety-critical 12 V systems where unidirectional clamping suffices and thermal robustness is mandatory.

FAQ
What is the clamping voltage of the TPSMC13A-2HE3_B/I at its rated peak pulse current?
The TPSMC13A-2HE3_B/I has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current (IPPM) of 82.4 A using a 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on the protected circuit during surge events. The TPSMC13A-2HE3_B/I maintains this clamping performance across its full operating temperature range, ensuring consistent protection behavior in automotive and industrial environments.
Is the TPSMC13A-2HE3_B/I suitable for automotive applications?
Yes, the TPSMC13A-2HE3_B/I is AEC-Q101 qualified and carries the HE3 suffix, indicating RoHS-compliance, halogen-free construction, and validation for automotive use. Its 185 °C maximum junction temperature, MSL Level 1 rating, and robust surge handling make it appropriate for under-hood and body electronics. The TPSMC13A-2HE3_B/I meets stringent automotive reliability requirements without requiring additional qualification testing by the end customer.
What does the "-2HE3_B/I" suffix indicate in TPSMC13A-2HE3_B/I?
The "-2HE3_B/I" suffix denotes the packaging and qualification configuration: "HE3" confirms RoHS-compliant, AEC-Q101-qualified, and halogen-free construction; "B" is the revision code; and "I" specifies 13-inch tape-and-reel packaging with 3500 units per reel. The "2" indicates the specific marking variant per Vishay's internal coding. This exact ordering code ensures traceability, compliance, and compatibility with automated SMT placement systems used in automotive manufacturing.
How does the TPSMC13A-2HE3_B/I compare to bi-directional TVS diodes like TPSMC13CA?
The TPSMC13A-2HE3_B/I is unidirectional and protects only against positive transients relative to ground, whereas TPSMC13CA provides symmetrical clamping for both polarities. The TPSMC13A-2HE3_B/I offers identical VBR, VC, and PPPM ratings but lower capacitance and better DC bias stability on power rails. Use the TPSMC13A-2HE3_B/I for 12 V supply line protection; choose TPSMC13CA only when protecting AC-coupled or bidirectional signal paths such as RS-232 or audio lines.
What PCB layout considerations apply to the TPSMC13A-2HE3_B/I?
Per Vishay's datasheet, the TPSMC13A-2HE3_B/I must be mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads at each terminal to achieve rated 1500 W pulse power. Keep traces short and wide between the TPSMC13A-2HE3_B/I and protected node/ground, minimize loop area, and orient the cathode band toward the line being protected. Avoid thermal vias under the body unless thermally modeled - the SMC package relies on pad conduction, not via stacks, for surge energy dissipation.
