Product details
Overview
SM6T7V5A-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, with 7.13 V minimum breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), 11.3 V clamping voltage at 53.0 A peak pulse current (IPPM), and 600 W peak pulse power rating per 10/1000 μs waveform - used to protect MOSFETs and sensor signal lines in automotive ECUs against inductive switching transients.
For engineers reviewing the SM6T7V5A-E3/5B datasheet, SM6T7V5A-E3/5B pinout, SM6T7V5A-E3/5B application, or SM6T7V5A-E3/5B equivalent, key selection criteria include verified clamping performance at 53 A, unidirectional polarity with cathode band marking, RoHS-compliant matte tin terminals, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a fast-acting shunt clamp during overvoltage events, leveraging a glass-passivated silicon junction to achieve low dynamic impedance and sub-nanosecond response time. Its unidirectional configuration provides forward conduction path only when reverse-biased beyond VBR, enabling precise protection of DC-biased signal or power rails.
The device is rated for 150 °C maximum junction temperature and exhibits 100 °C/W typical junction-to-ambient thermal resistance under standard PCB mounting. It meets JESD201 Class 2 whisker resistance and MSL Level 1 reflow profile (260 °C peak), supporting high-reliability industrial and automotive production.

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 VWM, 12.0 V VC @ 49.2 A; lower PPPM (400 W) | Limited to lower-energy transients; not rated for 600 W pulses | Select when cost sensitivity outweighs peak power margin and 53 A IPPM headroom is unnecessary |
| 1.5SMC7.5A | Higher-power SMC package (2.5× larger footprint); same VWM/VC; 1500 W PPPM | Requires PCB redesign; suited for primary-side AC input protection | Choose only if system-level surge testing demands >600 W absorption and board space permits SMC |
Compared with SMAJ7.5A and 1.5SMC7.5A, SM6T7V5A-E3/5B delivers optimal balance of 600 W surge capacity, SMB footprint compatibility, and 6.4 V standoff in cost-sensitive automotive and industrial designs - without requiring layout changes or sacrificing clamping precision.

FAQ
What is the clamping voltage of SM6T7V5A-E3/5B at its rated peak pulse current?
The SM6T7V5A-E3/5B has a maximum clamping voltage (VC) of 11.3 V when subjected to its rated peak pulse current of 53.0 A using the standard 10/1000 μs waveform. This value is measured under defined test conditions per JEDEC standards and ensures predictable overvoltage limiting for downstream components. The SM6T7V5A-E3/5B achieves this clamping performance while maintaining low leakage (<500 μA) at its 6.40 V stand-off voltage.
Is SM6T7V5A-E3/5B suitable for automotive applications?
SM6T7V5A-E3/5B is RoHS-compliant and commercial-grade; it is not AEC-Q101 qualified in this specific suffix. However, Vishay offers AEC-Q101 qualified versions under ordering codes such as SM6T7V5AHE3_B/I. For automotive use, SM6T7V5A-E3/5B may be deployed in non-safety-critical subsystems where qualification is not mandated, but design validation must confirm compliance with system-level stress requirements. Always verify qualification status via the full part number before automotive deployment.
What does the "E3/5B" suffix indicate in SM6T7V5A-E3/5B?
The "E3" suffix denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads. The "/5B" indicates packaging in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel. This format supports high-speed pick-and-place assembly and is compatible with standard SMT feeders. The SM6T7V5A-E3/5B thus combines environmental compliance, automated manufacturability, and logistics scalability for volume production.
How does SM6T7V5A-E3/5B compare to bidirectional TVS diodes like SM6T7V5CA?
SM6T7V5A-E3/5B is unidirectional and features a cathode band for polarity identification, whereas SM6T7V5CA is bidirectional with no polarity marking and symmetric clamping in both directions. The unidirectional SM6T7V5A-E3/5B provides lower leakage in DC-biased applications and avoids forward conduction on positive transients - making it preferred for protecting grounded signal lines or MOSFET gates. Bidirectional variants suit AC-coupled or floating lines where polarity is undefined.
What PCB pad layout is recommended for optimal thermal and electrical performance of SM6T7V5A-E3/5B?
Vishay specifies mounting SM6T7V5A-E3/5B on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power and 100 °C/W thermal resistance. Minimum pad dimensions are 0.060" × 0.086" (1.52 mm × 2.18 mm). Thermal vias under pads improve heat dissipation in high-duty-cycle applications. The SM6T7V5A-E3/5B's SMB package requires no special stencil design and aligns with IPC-7351B standard footprints.
