Product details
Overview
SM6T7V5AHM3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) in SMB (DO-214AA) package, with 7.13 V minimum breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), 11.3 V maximum clamping voltage at 53.0 A peak pulse current (IPPM), and 600 W peak pulse power rating per 10/1000 μs waveform. It protects MOSFETs and ICs against inductive switching transients in automotive sensor signal lines.
For engineers reviewing the SM6T7V5AHM3_B/I datasheet, SM6T7V5AHM3_B/I pinout, SM6T7V5AHM3_B/I application, or SM6T7V5AHM3_B/I equivalent, key selection criteria include verified clamping performance at 53.0 A, AEC-Q101 qualification status, halogen-free RoHS compliance, and SMB package thermal resistance of 100 °C/W junction-to-ambient.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, designed for fast transient suppression on DC power rails and low-voltage signal paths. Its glass-passivated junction ensures stable breakdown characteristics, and its low-inductance SMB package supports high-frequency surge response.
The device delivers 600 W peak pulse power handling under standardized 10/1000 μs waveform conditions, with thermal derating above 25 °C per Fig. 2 and maximum junction temperature of +150 °C. It meets J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker test requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Same SMB package, 7.5 V nominal VBR, but only 400 W PPPM; non-AEC-Q101 | Limited to commercial-grade industrial or consumer use; not qualified for automotive | Select when AEC-Q101 is not required and lower surge margin is acceptable |
| SMCJ7.0A | Higher 1500 W PPPM, larger SMC (DO-214AB) package, 7.0 V VBR min | Requires PCB layout change; suited for higher-energy transients in motor drives | Choose when system-level surge testing exceeds 600 W and board space permits SMC footprint |
Compared with SMAJ7.5A and SMCJ7.0A, SM6T7V5AHM3_B/I uniquely combines AEC-Q101 qualification, 600 W surge rating, and SMB footprint-making it optimal for space-constrained automotive sensor nodes where reliability and regulatory compliance are mandatory.

FAQ
What is the breakdown voltage tolerance for SM6T7V5AHM3_B/I?
The SM6T7V5AHM3_B/I has a specified breakdown voltage range of 7.13 V to 7.88 V at 10 mA test current, corresponding to ±5% tolerance around the nominal 7.5 V rating. This tight VBR distribution ensures consistent clamping behavior across production lots and supports predictable circuit protection design for the SM6T7V5AHM3_B/I.
Is SM6T7V5AHM3_B/I suitable for automotive applications?
Yes, SM6T7V5AHM3_B/I is AEC-Q101 qualified, halogen-free, and RoHS-compliant-meeting automotive reliability requirements for sensor interfaces, body control modules, and ADAS subsystems. Its +150 °C maximum junction temperature and MSL Level 1 rating make SM6T7V5AHM3_B/I appropriate for under-hood and cabin-mounted electronics.
What is the maximum clamping voltage of SM6T7V5AHM3_B/I at rated peak pulse current?
The SM6T7V5AHM3_B/I exhibits a maximum clamping voltage (VC) of 11.3 V when subjected to its rated peak pulse current of 53.0 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the official Vishay datasheet and defines the upper voltage limit imposed on protected circuitry during transient events for the SM6T7V5AHM3_B/I.
Does SM6T7V5AHM3_B/I have bidirectional capability?
No, SM6T7V5AHM3_B/I is a unidirectional TVS diode, identified by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., SM6T7V5CA). The SM6T7V5AHM3_B/I conducts only during reverse-biased overvoltage events and must be oriented with cathode toward the protected line.
What is the thermal resistance of SM6T7V5AHM3_B/I in standard mounting conditions?
The SM6T7V5AHM3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value governs power derating above 25 °C ambient and is critical for thermal design validation of the SM6T7V5AHM3_B/I in continuous or repetitive surge scenarios.
