Product details
Overview
SMB10J8.0A-M3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection with 8.0 V stand-off voltage, 13.6 V clamping voltage at 73.5 A peak pulse current, and 1000 W peak pulse power rating under 10/1000 μs waveform. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMB10J8.0A-M3/5B datasheet, SMB10J8.0A-M3/5B pinout, SMB10J8.0A-M3/5B application, or SMB10J8.0A-M3/5B equivalent, key selection criteria include clamping performance at rated surge current, unidirectional polarity, AEC-Q101 qualification status, and halogen-free RoHS compliance per M3 suffix.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients induced by inductive load switching or ESD events. Its glass-passivated junction ensures stable breakdown behavior, while low incremental surge resistance enables efficient energy diversion without thermal runaway.
The device is rated for -55 °C to +150 °C operating junction temperature and meets J-STD-020 MSL Level 1 with 260 °C reflow peak. Its 72 °C/W junction-to-ambient thermal resistance requires minimum 5.0 mm × 5.0 mm copper pad layout for full 1000 W rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A-M3/5B | Same SMB package, identical VWM (8.0 V), but lower PPPM (600 W) and IPPM (49.0 A) | Not suitable for 1000 W surge requirements; limited to lighter-duty consumer or non-automotive use | Select only when system-level surge stress is below 600 W and AEC-Q101 is not required |
| SMB10J8.0AHE3_B/I | Same electrical specs and package, but E3 suffix (RoHS-compliant commercial grade) instead of M3 (halogen-free) | Lacks halogen-free certification; not approved for automotive OEMs requiring strict material declarations | Choose for cost-sensitive industrial designs where halogen content is unrestricted |
Compared with SMBJ8.0A-M3/5B and SMB10J8.0AHE3_B/I, SMB10J8.0A-M3/5B uniquely combines 1000 W surge rating, AEC-Q101 qualification, and halogen-free compliance-making it the only option validated for high-stress automotive power rail protection with full material traceability.

FAQ
What is the clamping voltage of SMB10J8.0A-M3/5B at its rated peak pulse current?
The SMB10J8.0A-M3/5B has a maximum clamping voltage (VC) of 13.6 V at 73.5 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured and guaranteed per Vishay Document Number 88422, ensuring predictable overvoltage limiting for protected circuits during surge events.
Is SMB10J8.0A-M3/5B qualified for automotive applications?
Yes, SMB10J8.0A-M3/5B is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 09-Jan-2024. The M3 suffix denotes halogen-free, RoHS-compliant construction, and the "HM3" variant (e.g., SMB10J8.0AHM3_B/I) explicitly carries AEC-Q101 certification-validating its use in automotive powertrain, body, and chassis systems.
What does the "M3/5B" suffix indicate in SMB10J8.0A-M3/5B?
The "M3" suffix indicates halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance, while "/5B" specifies packaging in 13-inch diameter plastic tape and reel with 3200 units per reel. This format supports high-volume SMT assembly and satisfies automotive material compliance reporting requirements.
How does SMB10J8.0A-M3/5B differ from SMBJ8.0A-M3/5B?
SMB10J8.0A-M3/5B delivers 1000 W peak pulse power and 73.5 A IPPM, whereas SMBJ8.0A-M3/5B is rated for only 600 W and 49.0 A. Both share the same SMB package and 8.0 V stand-off, but SMB10J8.0A-M3/5B is designed for higher-energy transients such as ISO 7637-2 load dump, making it unsuitable for direct substitution without derating analysis.
What is the thermal resistance of SMB10J8.0A-M3/5B, and how does it affect layout?
SMB10J8.0A-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To sustain full 1000 W rating, PCB layout must provide this minimum pad area; reduced copper area increases junction temperature and requires derating per Figure 2 in the Vishay datasheet.
