Product details
Overview
SM6T7V5A-M3/52 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 rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial systems.
For engineers reviewing the SM6T7V5A-M3/52 datasheet, SM6T7V5A-M3/52 pinout, SM6T7V5A-M3/52 application, or SM6T7V5A-M3/52 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-M3/52 operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast response to ESD and inductive switching transients. Its clamping behavior is defined by a 10/1000 μs waveform test condition, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead).
It delivers 600 W peak pulse power dissipation under standardized surge conditions and supports 100 A non-repetitive forward surge current (10 ms half-sine). The device is rated for operation from –65 °C to +150 °C and exhibits ≤500 μA reverse leakage at 6.40 V stand-off voltage.
Key Specifications

|---|---|
| VWM | 6.40 V - Maximum continuous reverse operating voltage before significant leakage begins |
| VBR (min/max) | 7.13 V / 7.88 V at 10 mA - Ensures reliable avalanche conduction onset within tight tolerance band |
| VC @ IPPM | 11.3 V at 53.0 A - Clamped voltage during 10/1000 μs surge, limiting stress on downstream components |
| PPPM | 600 W - Peak transient energy absorption capability under standard lightning/surge waveform |
| IFSM | 100 A - Withstands single 10 ms half-sine surge without failure, critical for motor drive protection |
| TJ max | +150 °C - Enables use in under-hood automotive and high-temperature industrial environments |
| Package | SMB (DO-214AA) - Surface-mount footprint compatible with automated assembly and IPC-7351B standards |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges above 13.5 V. Use Value: Limits clamped voltage to 11.3 V at 53 A, preventing damage to 16 V-rated DC-DC converters and microcontrollers. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors connected to PLC inputs. IC Role / Device Role / Timing Role: TVS installed across sensor output and ground to absorb ESD and cable discharge events. Use Value: Sub-12 V clamping ensures sensor output stays within ADC input range while surviving ±8 kV contact ESD per IEC 61000-4-2. |
| Consumer Power Adapter Input Stage | MOSFET Gate Driver Transient Suppression |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters feeding USB-PD controllers. IC Role / Device Role / Timing Role: Standoff voltage (6.40 V) aligns with 5 V rail; clamps flyback spikes before they reach controller IC. Use Value: 600 W rating handles repetitive switching transients without degradation, extending adapter lifetime. | Use Scenario: Protecting high-side N-channel MOSFET gate drivers from Miller-induced voltage spikes. IC Role / Device Role / Timing Role: TVS placed between gate and source to clamp dv/dt-induced overshoot during switching transitions. Use Value: Fast response and low clamping voltage prevent unintended turn-on and gate oxide overstress in 40 V–60 V logic-level MOSFETs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Same SMB package, 7.5 V nominal VBR, 12.0 V VC @ 42.5 A, 400 W PPPM | Lower peak power rating limits use in higher-energy surge environments (e.g., ISO 7637-2 Pulse 5a) | Select SMAJ7.5A only where lower cost and reduced surge margin are acceptable for consumer-grade designs. |
| SMCJ7.0A | SMC (DO-214AB) package, 7.0 V nominal VBR, 11.2 V VC @ 53.6 A, 1500 W PPPM | Larger footprint and higher clamping energy require PCB layout revision and thermal derating analysis | Choose SMCJ7.0A when 1500 W surge handling is mandatory and board space permits larger SMC package. |
Compared with SMAJ7.5A and SMCJ7.0A, the SM6T7V5A-M3/52 provides optimal balance of 600 W surge capacity, SMB footprint compatibility, and 11.3 V clamping - making it ideal for space-constrained automotive and industrial modules requiring AEC-Q101-ready variants.

FAQ
What is the breakdown voltage tolerance of the SM6T7V5A-M3/52?
The SM6T7V5A-M3/52 has a specified breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, representing a ±5% tolerance around the nominal 7.5 V rating. This tight distribution ensures consistent clamping behavior across production lots and supports predictable circuit protection design. The SM6T7V5A-M3/52 maintains this specification under standard test conditions per JEDEC standards.
Is the SM6T7V5A-M3/52 AEC-Q101 qualified?
The SM6T7V5A-M3/52 itself is not AEC-Q101 qualified; however, the SM6T7V5AHM3 variant (with HM3 suffix) is fully AEC-Q101 qualified for automotive applications. The M3 suffix indicates halogen-free and RoHS-compliant construction but does not imply automotive qualification. For automotive use, specify SM6T7V5AHM3_X (where X denotes revision code) to ensure compliance with AEC-Q101 stress testing requirements.
What is the maximum clamping voltage of the SM6T7V5A-M3/52 during a surge event?
The SM6T7V5A-M3/52 has a maximum clamping voltage (VC) of 11.3 V at 53.0 A peak pulse current using the standard 10/1000 μs waveform. This value is measured under controlled test conditions with 0.2" × 0.2" copper pads per terminal. The clamping voltage remains stable across temperature and aging, enabling reliable overvoltage protection for 5 V and 12 V systems. The SM6T7V5A-M3/52 achieves this performance with low dynamic impedance and fast avalanche response.
Can the SM6T7V5A-M3/52 be used in bidirectional configurations?
No, the SM6T7V5A-M3/52 is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional operation, Vishay specifies the SM6T7V5CA-M3/52 (with CA suffix), which provides symmetrical clamping in both polarities. Using the SM6T7V5A-M3/52 in reverse-biased configurations risks permanent damage due to lack of reverse avalanche capability. Always verify polarity alignment during PCB layout for the SM6T7V5A-M3/52.
What is the thermal resistance of the SM6T7V5A-M3/52?
The SM6T7V5A-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and a junction-to-lead thermal resistance (RθJL) of 20 °C/W, measured under standard mounting conditions (0.2" × 0.2" copper pads). These values define power derating curves above 25 °C ambient and inform heatsinking decisions. The SM6T7V5A-M3/52 relies primarily on PCB copper for thermal dissipation rather than external heatsinks.
