Product details
Overview
SMB10J8.0-E3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features 8.0 V stand-off voltage (VWM), 13.6 V maximum clamping voltage at 50 A peak pulse current, and 1000 W peak pulse power rating with 10/1000 µs waveform. Used in automotive ECUs and industrial sensor interfaces to protect MOSFETs and microcontrollers from inductive switching transients.
For engineers reviewing the SMB10J8.0-E3/5B datasheet, SMB10J8.0-E3/5B pinout, SMB10J8.0-E3/5B application, or SMB10J8.0-E3/5B equivalent, key selection criteria include clamping performance under 50 A surge, unidirectional polarity with cathode band marking, RoHS-compliant matte tin terminals, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds 8.0 V (VWM), it transitions from high-impedance blocking to low-impedance conduction above its 8.89–9.83 V breakdown range (VBR at 1 mA). Its glass-passivated junction enables sub-nanosecond response to ESD and lightning-induced surges.
Thermal design relies on RθJA = 72 °C/W and RθJL = 20 °C/W, requiring minimum 5.0 mm × 5.0 mm copper pads per terminal per JEDEC standards. The device sustains 100 A non-repetitive forward surge (8.3 ms half-sine) and operates from –55 °C to +150 °C junction temperature.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt TVS placed between VBAT and chassis ground to clamp transients up to ISO 7637-2 Pulse 5a. Use Value: Limits voltage to ≤13.6 V during 1000 W surges, preventing damage to 16 V-rated LDOs and CAN transceivers. |
Use Scenario: Safeguarding analog outputs of pressure/temperature sensors in PLC I/O modules. IC Role / Device Role / Timing Role: Bidirectional clamping not applicable; unidirectional SMB10J8.0-E3/5B used on supply rail only. Use Value: Sub-10 ns response prevents latch-up in op-amps and ADC front-ends exposed to relay-coil flyback. |
| Consumer Power Adapter Input | MOSFET Gate Driver Protection |
Use Scenario: Secondary-side DC bus protection in USB-C PD adapters subject to hot-plug surges. IC Role / Device Role / Timing Role: Standoff at 8.0 V ensures no conduction during normal 9 V output; clamps >13.6 V spikes. Use Value: 1.0 µA leakage avoids efficiency loss in energy-sensitive 5–20 W adapters meeting DOE Level VI. |
Use Scenario: Shielding N-channel MOSFET gates from Miller-induced voltage overshoot during switching. IC Role / Device Role / Timing Role: Placed between gate and source to clamp negative-going transients below –0.7 V. Use Value: Fast response prevents gate oxide breakdown while maintaining <1 ns delay relative to driver output edge. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ8.0A-E3/5B | Same VWM (8.0 V), identical DO-214AA package, but rated for 600 W PPPM (vs. 1000 W) | Limited to lower-energy surges; unsuitable for ISO 7637-2 Pulse 5a compliance | Select SMB10J8.0-E3/5B when full 1000 W surge margin is required for automotive or industrial environments. |
| SAC8.0 | Higher VBR (9.5–10.5 V), same 1000 W rating, but SOD-123FL package (smaller footprint, higher RθJA) | Lower thermal mass limits sustained surge duty cycle; not AEC-Q101 qualified | Choose SMB10J8.0-E3/5B for AEC-Q101 validation and superior thermal dissipation in high-reliability designs. |
Compared with SMBJ8.0A-E3/5B and SAC8.0, SMB10J8.0-E3/5B delivers higher surge robustness in an automotive-qualified package with proven thermal performance on standard PCB layouts-making it the preferred choice where 1000 W clamping and AEC-Q101 compliance are mandatory.

FAQ
What is the clamping voltage of SMB10J8.0-E3/5B at its rated peak pulse current?
The SMB10J8.0-E3/5B has a maximum clamping voltage (VC) of 13.6 V when subjected to its specified peak pulse current of 50 A using the 10/1000 µs waveform. This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuits during surge events. The SMB10J8.0-E3/5B maintains this clamping performance across its operational temperature range.
Is SMB10J8.0-E3/5B suitable for automotive applications?
Yes, SMB10J8.0-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor modules. Its construction meets MSL Level 1, its terminals pass JESD 201 Class 1A whisker testing, and its 1000 W surge capability supports ISO 7637-2 Pulse 5a compliance. The SMB10J8.0-E3/5B data sheet confirms qualification status in the mechanical data section.
How does the SMB10J8.0-E3/5B differ from the SMBJ8.0A-E3/5B?
The SMB10J8.0-E3/5B provides 1000 W peak pulse power (PPPM), whereas the SMBJ8.0A-E3/5B is rated for 600 W. Both share the same DO-214AA package and 8.0 V stand-off voltage, but the SMB10J8.0-E3/5B achieves higher surge capacity through optimized chip geometry and thermal design. This makes SMB10J8.0-E3/5B appropriate for more demanding surge environments where the SMB10J8.0-E3/5B specification must be met.
What is the reverse leakage current of SMB10J8.0-E3/5B at its stand-off voltage?
The SMB10J8.0-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 µA when biased at its 8.0 V stand-off voltage (VWM) and tested at 25 °C. This low leakage ensures minimal power loss in always-on systems such as automotive telematics modules and battery-backed industrial controllers. The SMB10J8.0-E3/5B maintains this specification across its full operating temperature range.
Does SMB10J8.0-E3/5B have polarity marking, and how is it identified?
Yes, SMB10J8.0-E3/5B is unidirectional and features a visible cathode band on the package body, consistent with DO-214AA (SMB) standard marking. The banded end corresponds to the cathode terminal, which must be connected toward the higher-potential side of the protected line. This polarity marking is verified in the mechanical drawings and ordering information tables of the Vishay SMB10J8.0-E3/5B datasheet.
