Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5A | Same SMB package, 7.5 V VBR, but rated for 600 W with 10/1000 µs waveform and not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only | Select SMBJ7.5A when AEC-Q101 compliance is unnecessary and cost sensitivity outweighs qualification requirements |
| TPSMB7.5AHM3/5BT | Identical electrical specs and AEC-Q101 qualification; differs only in halogen-free molding compound (HM3 vs HE3) | No functional difference; HM3 variant required where halogen-free compliance is mandated (e.g., EU RoHS Annex II) | Choose TPSMB7.5AHM3/5BT if halogen-free material specification is enforced in your BOM or regional compliance program |
Compared with SMBJ7.5A and TPSMB7.5AHM3/5BT, the TPSMB7.5HE3/5BT provides identical surge performance and automotive qualification but uses standard RoHS-compliant (non-halogen-free) epoxy - making it optimal for cost-sensitive AEC-Q101 designs where halogen content is unrestricted.

FAQ
What is the exact breakdown voltage range for TPSMB7.5HE3/5BT?
The TPSMB7.5HE3/5BT has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, per Vishay Document #88406. This tolerance ensures predictable clamping onset across production lots and temperature extremes. The nominal value is 7.50 V, and the device maintains this specification under AEC-Q101 stress conditions. All TPSMB7.5HE3/5BT units are 100 % tested to verify VBR compliance before shipment.
Is TPSMB7.5HE3/5BT qualified to AEC-Q101?
Yes, TPSMB7.5HE3/5BT is fully AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document #88406, Rev. 23-Jan-2024). The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified variants. Qualification includes temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - validating suitability for automotive under-hood and chassis applications.
What is the maximum clamping voltage of TPSMB7.5HE3/5BT at rated surge current?
The TPSMB7.5HE3/5BT clamps to a maximum of 11.3 V at its rated peak pulse current of 53.1 A (10/1000 µs waveform), per the electrical characteristics table in Vishay's datasheet. This clamping voltage is measured under standardized test conditions and remains stable across -65 °C to +185 °C junction temperature, enabling predictable protection margin for downstream 12 V logic and interface ICs.
Does TPSMB7.5HE3/5BT have a unidirectional or bidirectional configuration?
TPSMB7.5HE3/5BT is strictly unidirectional, as stated in the Vishay datasheet "Features" section. It protects against reverse-polarity transients only - conducting when cathode voltage exceeds anode voltage by ≥VBR. It must be oriented with the cathode band toward the protected line and anode toward ground or lower potential. Bidirectional variants (e.g., TPSMB7.5CA) are separate part numbers and not interchangeable with TPSMB7.5HE3/5BT.
What is the package type and mounting requirement for TPSMB7.5HE3/5BT?
TPSMB7.5HE3/5BT uses the SMB (DO-214AA) surface-mount package, with mechanical dimensions specified in inches and millimeters on page 4 of Vishay Document #88406. For rated 600 W pulse power handling, it requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads at each terminal. The cathode is marked by a visible band; proper orientation is essential for correct clamping functionality in the TPSMB7.5HE3/5BT circuit layout.
