Product details
Overview
TPSMB13AHE3/5BT from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode designed for clamping inductive switching transients and lightning-induced surges on power rails and signal lines. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 18.2 V maximum clamping voltage at 33 A, and operates up to +185 °C junction temperature.
For engineers reviewing the TPSMB13AHE3/5BT datasheet, TPSMB13AHE3/5BT pinout, TPSMB13AHE3/5BT application, or TPSMB13AHE3/5BT equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, 185 °C thermal capability, and clamping performance under 10/1000 µs surge conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping across temperature, with a typical VBR temperature coefficient of +0.072 %/°C and low incremental surge resistance. Its 10/1000 µs waveform response ensures robust protection against automotive load-dump and industrial switching transients.
The device is rated for 75 A non-repetitive forward surge current (8.3 ms half-sine), exhibits ≤2 µA reverse leakage at VWM, and maintains full functionality under MSL Level 1 reflow conditions (260 °C peak). Cathode identification is marked by a color band on the SMB package body.
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 SMB package, identical VBR (12.4–13.7 V), but rated for 600 W with 10/1000 µs waveform and no AEC-Q101 qualification | Lacks automotive qualification; suitable for industrial/commercial use only | Select when AEC-Q101 is not required and cost optimization is prioritized |
| TPSMB13AHM3/5BT | Halogen-free variant of same base part; identical electrical specs, same AEC-Q101 qualification, and MSL Level 1 rating | Required for halogen-free compliance in EU/Asia OEM programs | Select when material compliance (e.g., IEC 61249-2-21) drives BOM requirements |
Compared with SMBJ13A and TPSMB13AHM3/5BT, the TPSMB13AHE3/5BT provides identical surge performance and thermal capability but distinguishes itself through RoHS-compliant, AEC-Q101-qualified construction-making it the preferred choice for automotive Tier 1 designs requiring traceable, high-reliability TVS protection without halogen restrictions.

FAQ
What is the breakdown voltage tolerance of TPSMB13AHE3/5BT?
The TPSMB13AHE3/5BT has a specified breakdown voltage range of 12.4 V (minimum) to 13.7 V (maximum) at 1 mA test current, with a nominal value of 13.0 V. This ±5% tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage detection in 12 V systems. The TPSMB13AHE3/5BT meets this specification under standardized test conditions per ANSI/IEEE C62.35.
Is TPSMB13AHE3/5BT qualified for automotive applications?
Yes, the TPSMB13AHE3/5BT is AEC-Q101 qualified, confirming its suitability for automotive electronic systems. This qualification includes stress testing for temperature cycling, high-temperature reverse bias, and ESD per JEDEC standards. The "HE3" suffix explicitly denotes RoHS-compliant, AEC-Q101-qualified construction, making the TPSMB13AHE3/5BT appropriate for under-hood and chassis-mounted modules.
What is the maximum clamping voltage of TPSMB13AHE3/5BT at rated surge current?
The TPSMB13AHE3/5BT has a maximum clamping voltage (VC) of 18.2 V at its peak pulse current (IPPM) of 33 A, measured using the standard 10/1000 µs waveform. This clamping level ensures protected circuitry remains within safe operating limits during transient events. The TPSMB13AHE3/5BT achieves this with low dynamic impedance, minimizing voltage overshoot during fast-rising surges.
Does TPSMB13AHE3/5BT have a unidirectional or bidirectional configuration?
The TPSMB13AHE3/5BT is a unidirectional TVS diode, meaning it clamps only positive-going transients relative to its cathode terminal. Its polarity is indicated by a color band marking the cathode end. This configuration is ideal for DC power rail protection where reverse voltage events are not expected. The TPSMB13AHE3/5BT is not rated for bidirectional operation.
What package type does TPSMB13AHE3/5BT use, and what are its mounting requirements?
The TPSMB13AHE3/5BT uses the SMB (DO-214AA) surface-mount package, with dimensions of 0.205" × 0.220" and a recommended copper pad layout per Vishay's outline drawing. It is rated MSL Level 1 and compatible with standard lead-free reflow profiles peaking at 260 °C. The TPSMB13AHE3/5BT requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads at each terminal for optimal thermal dissipation and surge current handling.
