Product details
Overview
TPSMB7.5AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 7.5 V nominal breakdown voltage (VBR), 6.4 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 185 °C maximum junction temperature, and SMB (DO-214AA) package - used to protect MOSFETs, ICs, and sensor interfaces in automotive power supplies.
For engineers reviewing the TPSMB7.5AHM3_A/I datasheet, TPSMB7.5AHM3_A/I pinout, TPSMB7.5AHM3_A/I application, or TPSMB7.5AHM3_A/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, clamping performance at rated surge current, thermal derating curves, and halogen-free RoHS-compliant sourcing details.
Technical Context
This TVS diode operates as a unidirectional clamping device with a silicon junction passivated anisotropic rectifier structure, enabling fast response (<1 ns) and low incremental surge resistance. Its 7.13–7.88 V breakdown range at 10 mA test current ensures precise overvoltage thresholding under defined thermal conditions.
The device is rated for 75 A non-repetitive forward surge current (8.3 ms half-sine), 53.1 V maximum clamping voltage at 53.1 A peak pulse current (IPPM), and exhibits +0.052 %/°C temperature coefficient of VBR, supporting stable operation across -65 °C to +185 °C junction range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 7.13 / 7.50 / 7.88 V at 10 mA - defines precise clamping initiation threshold under standard test conditions |
| VWM | 6.4 V - maximum continuous reverse working voltage before leakage exceeds 250 µA |
| IPPM | 53.1 A (10/1000 µs waveform) - peak surge current it safely clamps without failure |
| VC | 11.3 V at IPPM - maximum clamped voltage seen by protected circuit during full-rated surge |
| PPPM | 600 W - peak pulse power handling capability under standardized 10/1000 µs transient |
| TJ max. | +185 °C - enables use in under-hood automotive environments and high-temperature industrial PCBs |
| Polarity | Unidirectional - protects against positive-going transients only; cathode marked with band |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, MSL Level 1 (260 °C reflow peak), matte tin-plated terminals.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5AHE3_A/I | Same SMB package, identical VBR (7.13–7.88 V), but rated for 600 W with 10/1000 µs waveform and not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial designs where AEC-Q101 is not mandated | Select when cost sensitivity outweighs automotive reliability requirements and halogen-free material is not required |
| TPSMB7.5AHE3_A/I | Identical electrical specs and SMB package, but uses standard RoHS-compliant molding compound (not halogen-free) and lacks AEC-Q101 certification | Approved for general-purpose electronics; not approved for automotive under hood or safety-critical modules | Choose when halogen-free content is not required and AEC-Q101 qualification is unnecessary for end-use environment |
Compared with TPSMB7.5AHM3_A/I, SMBJ7.5AHE3_A/I offers identical clamping performance but omits halogen-free and AEC-Q101 validation, while TPSMB7.5AHE3_A/I retains RoHS compliance but excludes both halogen-free status and automotive qualification - making TPSMB7.5AHM3_A/I the only variant meeting all three criteria.

FAQ
What is the clamping voltage of the TPSMB7.5AHM3_A/I at its rated peak pulse current?
The TPSMB7.5AHM3_A/I has a maximum clamping voltage (VC) of 11.3 V when subjected to its rated peak pulse current (IPPM) of 53.1 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees that protected circuitry will not experience voltages exceeding 11.3 V during such transient events. The TPSMB7.5AHM3_A/I achieves this with low dynamic impedance, ensuring effective energy diversion away from sensitive components.
Is the TPSMB7.5AHM3_A/I qualified for automotive applications?
Yes, the TPSMB7.5AHM3_A/I is AEC-Q101 qualified, as confirmed in Vishay's official datasheet (Document Number: 88406, Revision: 23-Jan-2024). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and accelerated life testing - validating its suitability for under-hood and safety-critical automotive subsystems. The "HM3" suffix explicitly denotes halogen-free, RoHS-compliant, and AEC-Q101-qualified construction for the TPSMB7.5AHM3_A/I.
What does the "HM3" suffix mean in TPSMB7.5AHM3_A/I?
The "HM3" suffix in TPSMB7.5AHM3_A/I indicates halogen-free, RoHS-compliant, and AEC-Q101-qualified construction per Vishay's ordering nomenclature. It distinguishes this variant from "HE3" (RoHS-compliant and AEC-Q101 qualified but not halogen-free) and standard "A" versions. The "_A/I" denotes revision A in 13-inch tape-and-reel packaging (3200 units per reel), confirming full traceability and process control for production use.
How does the TPSMB7.5AHM3_A/I compare to the TPSMB7.5AHE3_A/I in terms of material compliance?
The TPSMB7.5AHM3_A/I uses halogen-free molding compound meeting IEC 61249-2-21, whereas the TPSMB7.5AHE3_A/I is RoHS-compliant but contains brominated flame retardants. Both meet RoHS Directive 2011/65/EU, but only the HM3 variant satisfies stricter halogen-free requirements common in automotive and green electronics programs. The TPSMB7.5AHM3_A/I also carries AEC-Q101 qualification, unlike the HE3 version which shares electrical specs but lacks automotive validation.
What is the maximum operating junction temperature for the TPSMB7.5AHM3_A/I?
The TPSMB7.5AHM3_A/I has a maximum operating junction temperature (TJ) of +185 °C, as specified in the Vishay datasheet. This rating enables reliable operation in high-ambient environments such as engine compartments or enclosed industrial power supplies. Derating curves in Figure 2 confirm usable pulse power down to 100 % at 25 °C ambient and ~40 % at 125 °C ambient - critical for thermal design of the TPSMB7.5AHM3_A/I in dense layouts.
