Product details
Overview
TPSMC7.5AHM3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features 7.5 V nominal breakdown voltage (VBR), 6.4 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 133 V maximum clamping voltage at 133 A peak pulse current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the TPSMC7.5AHM3_B/I datasheet, TPSMC7.5AHM3_B/I pinout, TPSMC7.5AHM3_B/I application, or TPSMC7.5AHM3_B/I equivalent, key selection criteria include unidirectional polarity, 185 °C junction temperature rating, halogen-free RoHS-compliant construction, MSL Level 1 moisture sensitivity, and compatibility with high-reliability automotive and industrial surge protection layouts.
Technical Context
This TVS diode operates as a voltage-clamping protection device using passivated anisotropic rectifier technology. Its 7.5 V nominal breakdown voltage ensures reliable triggering above system operating voltage while maintaining low leakage (<500 µA at VWM) at 25 °C and <5000 µA at 150 °C.
The device delivers 1500 W peak pulse power handling per 10/1000 µs waveform with 133 V clamping voltage at rated IPPM, supported by low incremental surge resistance and sub-nanosecond response time. It is rated for TJ = –65 °C to +185 °C and meets JESD201 Class 2 whisker resistance.

Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs, lighting modules, and body control units from load dump and inductive switching transients.

Use Value: Tight 7.13–7.88 V VBR tolerance and 11.3 V clamping ensure safe shutdown of connected devices before destructive overvoltage occurs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.5AHE3_A/H | Lower PPPM (600 W), SMB package (smaller footprint), same VBR range and AEC-Q101 qualification | Better suited for space-constrained consumer PCBs; insufficient for 1500 W automotive load dump | Select when board area is critical and surge energy is ≤600 W |
| TPSMC7.5AHE3_B/I | Same electrical specs and SMC package, but RoHS-compliant without halogen-free certification | Acceptable for non-automotive industrial use where halogen-free is not mandated | Choose when halogen-free requirement is waived and cost optimization is prioritized |
Compared with TPSMC7.5AHM3_B/I, SMBJ7.5AHE3_A/H offers smaller size but reduced surge capacity, while TPSMC7.5AHE3_B/I matches form-factor and performance but lacks halogen-free compliance-making the HM3 variant essential for strict automotive supply chains.

FAQ
What is the maximum clamping voltage of the TPSMC7.5AHM3_B/I under full-rated surge conditions?
The TPSMC7.5AHM3_B/I exhibits a maximum clamping voltage (VC) of 11.3 V when subjected to its rated peak pulse current (IPPM) of 133 A using the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees that protected circuits experience no more than 11.3 V during worst-case transient events, making TPSMC7.5AHM3_B/I suitable for safeguarding 5 V and 3.3 V logic interfaces.
Is the TPSMC7.5AHM3_B/I suitable for automotive applications?
Yes, the TPSMC7.5AHM3_B/I is AEC-Q101 qualified and built with halogen-free, RoHS-compliant materials-meeting stringent automotive reliability requirements. Its 185 °C maximum junction temperature, MSL Level 1 rating, and JESD201 Class 2 whisker resistance make TPSMC7.5AHM3_B/I appropriate for engine control units, ADAS sensors, and infotainment power rails where thermal and mechanical robustness are mandatory.
What does the "HM3" suffix indicate in TPSMC7.5AHM3_B/I?
The "HM3" suffix in TPSMC7.5AHM3_B/I designates halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. The "H" denotes halogen-free material compliance, "M3" confirms AEC-Q101 qualification and matte tin plating, and the "B/I" specifies packaging in 13-inch tape-and-reel format with 3500 units per reel-ensuring TPSMC7.5AHM3_B/I meets Tier 1 automotive supplier traceability and process control standards.
How does the TPSMC7.5AHM3_B/I compare to bidirectional TVS diodes?
The TPSMC7.5AHM3_B/I is unidirectional and protects only against positive-going transients on the cathode-to-anode path. Unlike bidirectional variants, it provides lower leakage (<500 µA at 6.4 V) and tighter VBR tolerance-ideal for DC power line protection. TPSMC7.5AHM3_B/I cannot replace bidirectional TVS in AC-coupled or differential signal paths where negative transients must also be suppressed.
What is the recommended PCB layout for optimal performance of the TPSMC7.5AHM3_B/I?
For optimal transient suppression, mount TPSMC7.5AHM3_B/I with minimal trace length between cathode and protected node, and connect anode directly to a low-inductance ground plane. Use 8.0 mm × 8.0 mm copper pads per terminal as specified in the datasheet to sustain 1500 W surge dissipation. Avoid routing sensitive traces near the device, and ensure thermal relief is minimized to maintain clamping integrity during repetitive surges-critical for sustained TPSMC7.5AHM3_B/I reliability.
