Product details
Overview
TPSMB10HE3/5BT from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive and lightning-induced transients on power and signal lines. It features 10 V breakdown voltage (VBR = 9.5–10.5 V at 1 mA), 8.55 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 14.5 V clamping voltage at 41.4 A peak current, and operates up to +185 °C junction temperature - ideal for automotive power rail protection.
For engineers reviewing the TPSMB10HE3/5BT datasheet, TPSMB10HE3/5BT pinout, TPSMB10HE3/5BT application, or TPSMB10HE3/5BT equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and verified 185 °C thermal capability for under-hood automotive electronics.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance across temperature. Its 10/1000 µs waveform rating of 600 W and low incremental surge resistance ensure robust energy absorption during repetitive transients, while the 14.5 V clamping voltage at 41.4 A limits stress on downstream MOSFETs and ICs.
The device is optimized for high-reliability environments: it meets AEC-Q101 qualification, supports operation from –65 °C to +185 °C, and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards - critical for automotive and industrial PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 9.5 / 10.0 / 10.5 V at 1 mA - defines precise voltage threshold where clamping begins, enabling accurate overvoltage protection design |
| VWM | 8.55 V - maximum continuous reverse working voltage; ensures no leakage conduction during normal 12 V automotive system operation |
| VC @ IPPM | 14.5 V at 41.4 A - clamping voltage under full 600 W surge; keeps protected circuitry below safe 16 V logic/power thresholds |
| PPPM | 600 W (10/1000 µs) - peak pulse power handling capacity; sustains repeated load-dump and ISO 7637-2 transient events |
| TJ max. | +185 °C - enables placement near hot components (e.g., engine control units) without derating or failure risk |
| Polarity | Unidirectional - provides reverse-biased clamping only; suited for DC power line protection with defined ground reference |
| MSL Level | Level 1 (J-STD-020) - allows unlimited floor life and reflow at 260 °C peak, eliminating bake requirements before SMT assembly |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, cathode indicated by color band. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H). Molded compound meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection to protected circuit ground | Completes clamping path during transient; must be routed with low-inductance trace to minimize voltage overshoot |
| Cathode | High-side connection to protected line (e.g., 12 V rail) | Receives surge energy; color band identifies this terminal for correct PCB orientation and polarity verification |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same SMB package, 600 W rating, but lower TJ max. (150 °C); not AEC-Q101 qualified | Limited to commercial/industrial use; unsuitable for under-hood automotive deployment | Select when cost sensitivity outweighs automotive qualification and extended temperature needs |
| TPSMB10AHM3/5BT | Identical electrical specs and AEC-Q101 qualification; halogen-free molding compound instead of standard RoHS-compliant | Required for OEMs enforcing halogen-free material declarations (e.g., VW TL 52282) | Choose for automotive programs mandating halogen-free compliance without compromising performance or qualification |
