Product details
Overview
SM6T7V5AHE3_B/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 7.13–7.88 V breakdown voltage at 10 mA, and 11.3 V clamping voltage at 53.0 A peak pulse current. It provides robust ESD and surge protection for low-voltage signal lines in automotive sensor interfaces.
For engineers reviewing the SM6T7V5AHE3_B/H datasheet, SM6T7V5AHE3_B/H pinout, SM6T7V5AHE3_B/H application, or SM6T7V5AHE3_B/H equivalent, key selection criteria include clamping voltage margin relative to IC VDD, AEC-Q101 qualification status, unidirectional polarity with cathode band marking, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This TVS diode operates as a shunt-clamping device triggered by reverse-biased avalanche breakdown. Its glass-passivated junction ensures stable leakage (<500 μA at 6.40 V stand-off) and low inductance for fast response to transients up to 10/1000 μs waveform.
Designed for surface-mount automated placement, it meets MSL level 1 (260 °C reflow peak) and supports automotive-grade reliability via AEC-Q101 qualification - confirmed by HE3 suffix and Vishay's ordering code structure for qualified parts.

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-E3/52 | Same SMB package, 7.5 V nominal VBR, but not AEC-Q101 qualified; RθJA = 110 °C/W | Targeted at commercial/industrial use only; lacks automotive stress validation | Select when AEC-Q101 is not required and cost optimization is prioritized |
| 1.5SMC7.5A | Higher power (1500 W), larger SMC (DO-214AB) package, VBR = 7.5–8.33 V, no AEC-Q101 | Used where higher surge margin is needed and board space allows larger footprint | Choose for non-automotive systems requiring >1 kW surge handling and relaxed thermal constraints |
Compared with SMAJ7.5A-E3/52 and 1.5SMC7.5A, SM6T7V5AHE3_B/H uniquely combines AEC-Q101 qualification, SMB footprint, and verified 600 W clamping performance - making it the preferred choice for space-constrained automotive signal-line protection where qualification and reliability are mandatory.

FAQ
What is the clamping voltage of SM6T7V5AHE3_B/H at its rated peak pulse current?
The SM6T7V5AHE3_B/H has a maximum clamping voltage (VC) of 11.3 V at 53.0 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Vishay's test conditions and ensures predictable overvoltage limiting for protected circuits. The SM6T7V5AHE3_B/H maintains this clamping performance across its qualified operating temperature range.
Is SM6T7V5AHE3_B/H qualified for automotive applications?
Yes, SM6T7V5AHE3_B/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its part number and Vishay's official ordering information. This qualification covers stress tests including high-temperature operating life, temperature cycling, and humidity testing - validating its use in automotive powertrain, body electronics, and ADAS sensor modules.
What does the "_B/H" suffix indicate in SM6T7V5AHE3_B/H?
The "_B/H" suffix in SM6T7V5AHE3_B/H denotes packaging configuration: "H" specifies 7-inch diameter plastic tape and reel, and "B" indicates revision level B per Vishay's internal documentation. This matches Vishay's ordering convention shown in the SM6T datasheet revision 09-Jan-2024 (Document Number: 88385).
How does SM6T7V5AHE3_B/H differ from bidirectional variants like SM6T7V5CA?
SM6T7V5AHE3_B/H is unidirectional, with cathode marked by a band and intended for DC-biased lines; SM6T7V5CA is bidirectional, unmarked, and used in AC-coupled or symmetric signal paths. Their breakdown voltages are identical, but SM6T7V5AHE3_B/H cannot replace SM6T7V5CA in applications requiring symmetrical clamping in both polarities.
What is the maximum reverse leakage current for SM6T7V5AHE3_B/H at its stand-off voltage?
At the specified stand-off voltage (VWM) of 6.40 V, the SM6T7V5AHE3_B/H exhibits a maximum reverse leakage current (ID) of 500 μA at TA = 25 °C. This low leakage ensures minimal power loss and avoids interference with sensitive upstream circuitry such as voltage references or high-impedance sensor nodes.
