Product details
Overview
SM6T7V5A-M3/5B 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 (VC) at 53.0 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems.
For engineers reviewing the SM6T7V5A-M3/5B datasheet, SM6T7V5A-M3/5B pinout, SM6T7V5A-M3/5B application, or SM6T7V5A-M3/5B equivalent, key selection criteria include unidirectional polarity, 150 °C max junction temperature, halogen-free RoHS-compliant construction (M3 suffix), low-inductance SMB package, and AEC-Q101 qualification eligibility via HM3 variant.
Technical Context
The SM6T7V5A-M3/5B operates as a unidirectional clamping device with glass-passivated junction, optimized for fast response to ESD and inductive switching transients. Its electrical behavior is defined by precise VBR (7.13–7.88 V @ 10 mA), VWM (6.40 V), and VC (11.3 V @ 53.0 A), ensuring reliable overvoltage protection without forward conduction during normal operation.
Thermal performance is characterized by RθJA = 100 °C/W and RθJL = 20 °C/W, supporting stable operation up to 150 °C junction temperature. The device meets J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker resistance requirements, with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102.
Key Specifications

|---|---|
| VBR (min/max) | 7.13 V / 7.88 V @ 10 mA - defines precise clamping onset threshold under standardized test conditions |
| VWM | 6.40 V - maximum continuous reverse voltage before leakage exceeds 500 μA, sets operating margin below breakdown |
| VC @ IPPM | 11.3 V @ 53.0 A - clamped voltage during 600 W transient, determines protected circuit's worst-case overvoltage stress |
| PPPM | 600 W (10/1000 μs) - peak surge energy handling capacity, critical for inductive load switching protection |
| TJ max | 150 °C - maximum allowable junction temperature, constrains thermal design and derating above 25 °C ambient |

IC Role / Device Role / Timing Role: Unidirectional suppressor placed between DC feed and ground plane to clamp flyback spikes from cable impedance mismatches. Use Value: Delivers 11.3 V clamping at 53 A, limiting stress on IEEE 802.3af/at compliant interface ICs and maintaining safe operating area margins. |
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 @ 50 A, 400 W PPPM | Lower peak power rating limits use in high-energy automotive load-dump scenarios | Select when cost sensitivity outweighs 600 W requirement and thermal derating allows 400 W operation |
| SMCJ7.0A | Larger SMC (DO-214AB) package, 7.0 V VWM, 11.2 V VC @ 53.5 A, 1500 W PPPM | Higher power and larger footprint suit industrial motor drives but require PCB layout change | Choose for higher surge immunity where board space permits and 1500 W capability is needed |

FAQ
What is the exact breakdown voltage range for SM6T7V5A-M3/5B?
The SM6T7V5A-M3/5B has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V when tested at 10 mA DC current, per Vishay Document Number 88385. This specification ensures predictable clamping onset across production lots and temperature ranges, directly supporting design margin calculations for protected circuits. The SM6T7V5A-M3/5B maintains this tolerance under standard JEDEC test conditions and is verified per AEC-Q101 stress protocols for qualified variants.
Is SM6T7V5A-M3/5B suitable for automotive applications?
The SM6T7V5A-M3/5B itself is a commercial-grade halogen-free part (M3 suffix); however, its automotive-qualified counterpart is SM6T7V5AHM3_X (e.g., SM6T7V5AHM3_B). While SM6T7V5A-M3/5B shares identical electrical specs and SMB packaging, only HM3-suffixed versions undergo full AEC-Q101 stress testing. For non-safety-critical automotive subsystems where qualification is not mandated, SM6T7V5A-M3/5B remains widely deployed due to its proven reliability and thermal robustness.
What does the "M3/5B" suffix indicate in SM6T7V5A-M3/5B?
The "M3" suffix denotes halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance, while "/5B" specifies packaging in 13-inch diameter plastic tape and reel containing 3200 units. This format supports high-speed SMT placement and aligns with IPC-7351 standards for SMB footprints. The SM6T7V5A-M3/5B is fully compatible with standard reflow profiles including peak temperatures up to 260 °C per J-STD-020 MSL Level 1.
How does SM6T7V5A-M3/5B compare to bidirectional TVS diodes like SM6T7V5CA?
The SM6T7V5A-M3/5B is unidirectional and features a cathode band for polarity-sensitive placement, whereas SM6T7V5CA is bidirectional with no polarity marking and symmetric clamping in both directions. Their VBR, VWM, and VC values differ slightly due to internal structure - SM6T7V5CA has VBR = 7.13–7.88 V in each direction but requires no ground-reference orientation. Use SM6T7V5A-M3/5B for DC power rails; choose SM6T7V5CA for AC-coupled or floating signal lines.
What is the maximum clamping voltage of SM6T7V5A-M3/5B under surge conditions?
The SM6T7V5A-M3/5B exhibits a maximum clamping voltage (VC) of 11.3 V when subjected to a 10/1000 μs waveform with a peak pulse current (IPPM) of 53.0 A. This value is measured per Figure 1 and Table 1 in Vishay Document 88385 and represents the worst-case voltage imposed on protected circuitry during standardized surge events. The SM6T7V5A-M3/5B maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C).
