Product details
Overview
TPSMB10AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 10 V breakdown voltage (VBR), 8.55 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 14.5 V clamping voltage at 41.4 A, and operates up to +185 °C junction temperature - deployed in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMB10AHM3_A/I datasheet, TPSMB10AHM3_A/I pinout, TPSMB10AHM3_A/I application, or TPSMB10AHM3_A/I equivalent, key selection criteria include its AEC-Q101 qualification, halogen-free RoHS-compliant HM3 suffix, SMB (DO-214AA) package with cathode band polarity marking, and verified 75 A IFSM surge capability under 8.3 ms half-sine conditions.
Technical Context
The TPSMB10AHM3_A/I employs passivated anisotropic rectifier technology optimized for high-temperature stability and low incremental surge resistance. Its unidirectional architecture provides fast response time and excellent clamping performance during transient events such as load dump or ESD coupling on DC power inputs.
Designed for automotive-grade reliability, it meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, supports 0.01 % duty cycle repetitive operation, and delivers consistent VBR temperature coefficient of +0.064 %/°C - enabling stable overvoltage protection across extended thermal ranges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Same SMB package, 10 V VBR, but rated for 600 W with 10/1000 µs waveform and not AEC-Q101 qualified | Lacks automotive qualification and halogen-free certification; suitable for commercial-grade power supplies only | Select SMBJ10A only if AEC-Q101 and HM3 environmental compliance are not required |
| TPSMB10AHM3_A/H | Identical electrical specs and construction; differs only in tape-and-reel packaging (750 pcs vs. 3200 pcs per reel) | No functional difference; choice depends solely on production volume and SMT line feeder compatibility | Choose TPSMB10AHM3_A/H for low-volume prototyping or small-batch assembly where 7" reels are preferred |
Compared with SMBJ10A and TPSMB10AHM3_A/H, the TPSMB10AHM3_A/I offers guaranteed automotive qualification and halogen-free compliance in a high-volume 13" reel format - making it the optimal choice for Tier 1 automotive suppliers requiring traceable, lifecycle-managed components.

FAQ
What is the breakdown voltage tolerance of the TPSMB10AHM3_A/I?
The TPSMB10AHM3_A/I has a specified breakdown voltage range of 9.5 V (minimum) to 10.5 V (maximum) at 1 mA test current, with a typical value of 10.0 V. This ±5 % tolerance ensures consistent clamping behavior across production lots and supports reliable design margining for 12 V systems where transient thresholds must remain predictable under thermal stress.
Is the TPSMB10AHM3_A/I suitable for bidirectional transient protection?
No, the TPSMB10AHM3_A/I is unidirectional only, as confirmed in the Vishay datasheet. It protects against positive-going transients on a line referenced to ground. For bidirectional protection (e.g., data lines or AC-coupled signals), a different device such as the SMBJ10CA or a dedicated bidirectional TVS array must be used - the TPSMB10AHM3_A/I does not provide symmetrical clamping.
Does the TPSMB10AHM3_A/I meet AEC-Q101 requirements?
Yes, the TPSMB10AHM3_A/I is explicitly AEC-Q101 qualified, as stated in the Vishay datasheet under "FEATURES" and "ORDERING INFORMATION". The HM3 suffix denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction - making it suitable for automotive applications including engine control, ADAS, and body electronics.
What is the maximum clamping voltage of the TPSMB10AHM3_A/I at rated surge current?
The maximum clamping voltage (VC) of the TPSMB10AHM3_A/I is 14.5 V at 41.4 A peak pulse current (IPPM) using the 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and is critical for ensuring downstream components like 12 V logic ICs remain within absolute maximum ratings.
How does the TPSMB10AHM3_A/I differ from the HE3-suffix version?
The TPSMB10AHM3_A/I uses halogen-free molding compound and meets JESD201 Class 2 whisker resistance, whereas the HE3-suffix variant is RoHS-compliant and AEC-Q101 qualified but not halogen-free. Both share identical electrical characteristics and package dimensions; the HM3 version adds environmental compliance for stricter automotive and industrial sustainability mandates.
