Product details
Overview
SM6T7V5AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 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), 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification for automotive use.
For engineers reviewing the SM6T7V5AHE3_A/H datasheet, SM6T7V5AHE3_A/H pinout, SM6T7V5AHE3_A/H application, or SM6T7V5AHE3_A/H equivalent, key selection criteria include clamping performance under 10/1000 μs surge, unidirectional polarity with cathode band marking, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
The SM6T7V5AHE3_A/H operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its 7.13–7.88 V breakdown range at 10 mA test current. Its low-inductance SMB package enables fast response to ESD and lightning-induced transients while maintaining stable clamping up to 150 °C junction temperature.
It delivers 600 W peak pulse power per 10/1000 μs waveform with a maximum clamping voltage of 11.3 V at 53.0 A, limiting voltage stress on downstream ICs and MOSFETs. The device meets J-STD-020 MSL Level 1 and supports reflow up to 260 °C peak, ensuring robustness in high-volume automotive PCB assembly.

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 VWM (6.4 V), higher VC (12.0 V @ 49.2 A), lower PPPM (400 W), SMA package (larger footprint) | Lacks AEC-Q101 qualification; not recommended for automotive under-hood use | Select if cost-sensitive industrial designs accept reduced surge margin and larger board area |
| 1.5SMC7.5A | Same VBR/VWM, identical PPPM (600 W), but SMC package (DO-214AB) - 2.5 mm wider, higher RθJA (85 °C/W) | Higher thermal resistance reduces sustained surge capability in compact enclosures | Choose only when existing layout uses SMC footprint and thermal derating is verified for ambient conditions |
Compared with SMAJ7.5A and 1.5SMC7.5A, the SM6T7V5AHE3_A/H provides AEC-Q101 qualification, tighter VBR tolerance (±5%), lower clamping voltage, and optimized SMB thermal profile - making it the preferred choice for space-constrained, automotive-grade transient protection where reliability and consistent clamping are critical.

FAQ
What is the polarity configuration of SM6T7V5AHE3_A/H?
The SM6T7V5AHE3_A/H is a unidirectional TVS diode, with the cathode identified by a visible band on the SMB package. This configuration allows it to conduct only during reverse overvoltage events, making it suitable for DC power line and signal line protection where polarity is fixed. Its forward voltage drop is not specified for continuous conduction, as it is not intended for rectification.
Does SM6T7V5AHE3_A/H meet automotive qualification standards?
Yes, SM6T7V5AHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix in its ordering code. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD, validating its suitability for automotive applications such as body control modules, infotainment power supplies, and ADAS sensor interfaces.
What is the maximum clamping voltage of SM6T7V5AHE3_A/H under surge conditions?
The SM6T7V5AHE3_A/H has a maximum clamping voltage (VC) of 11.3 V at 53.0 A peak pulse current, measured using the standard 10/1000 μs waveform. This value ensures downstream 5 V and 3.3 V logic circuits remain within safe operating voltage margins during transient events, provided layout minimizes parasitic inductance.
Can SM6T7V5AHE3_A/H be used in bidirectional applications?
No, SM6T7V5AHE3_A/H is unidirectional only. For bidirectional protection, Vishay offers the CA-suffixed variant (e.g., SM6T7V5CA). Using SM6T7V5AHE3_A/H in bidirectional configurations would result in forward conduction during negative transients, potentially causing failure or incorrect clamping behavior.
What is the thermal resistance and how does it affect SM6T7V5AHE3_A/H's surge handling?
The SM6T7V5AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W. This value directly impacts its ability to dissipate heat after repeated surges; at elevated ambient temperatures (>25 °C), its peak pulse power must be derated per Figure 2 in the datasheet to avoid exceeding the 150 °C maximum junction temperature.
