Product details
Overview
SMBJ100D-M3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, with 100 V standoff voltage (VWM), 113–121 V breakdown voltage (VBR) at 1 mA, 159 V clamping voltage (VC) at 3.77 A peak pulse current, and 600 W peak pulse power rating per 10/1000 μs waveform. It protects MOSFETs and ICs against inductive switching transients in industrial power supplies.
For engineers reviewing the SMBJ100D-M3/I datasheet, SMBJ100D-M3/I pinout, SMBJ100D-M3/I application, or SMBJ100D-M3/I equivalent, key selection criteria include unidirectional polarity, 100 V stand-off rating, 159 V clamping performance at 3.77 A, M3 halogen-free RoHS-compliant construction, and SMB package thermal resistance of 125 °C/W (junction-to-ambient on minimum pad layout).
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (<0.5 μA leakage at 100 V), then rapidly avalanches when reverse voltage exceeds 113 V to clamp transient energy. Its 10/1000 μs waveform response enables suppression of lightning-induced surges and inductive kickback in DC power rails.
Designed for surface-mount assembly on PCBs with minimum 5.0 mm × 5.0 mm copper pad area, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C), JESD 201 Class 2 whisker resistance, and UL 497B recognition (QVGQ2 file E136766) for both uni- and bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 100 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 113 V / 121 V at 1 mA - tight ±3.5 % tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 159 V at 3.77 A - clamping voltage defines worst-case overvoltage seen by protected circuit |
| PPPM | 600 W - peak surge power handling capability with standard 10/1000 μs test waveform |
| ID @ VWM | ≤0.5 μA - ultra-low leakage preserves efficiency in high-impedance sensor or bias networks |
| TJ max | +150 °C - enables operation in under-hood automotive or enclosed industrial enclosures |
| RθJA | 125 °C/W - thermal resistance on minimum recommended PCB pad layout dictates derating above 25 °C ambient |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity marked with cathode band on one end. Matte tin-plated leads, halogen-free, RoHS-compliant, industrial grade (M3 suffix).

Key Features
| Feature | Design Value |
|---|---|
| ±3.5 % VBR tolerance | Enables precise coordination with downstream overvoltage protection thresholds without margin stacking |
| 600 W PPPM (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) in properly designed layouts |

| UL 497B recognized (E136766) | Validates suitability for telecom and industrial equipment requiring third-party safety certification |
| JESD 201 Class 2 whisker resistance | Ensures long-term reliability in high-humidity or high-temperature storage environments |
Applications
| Industrial Motor Drives | Telecom Power Feeds |
|---|---|
Use Scenario: Protection of gate drivers and bus sensing circuits against flyback voltage from 48 V DC motor coils during PWM switching. IC Role / Device Role / Timing Role: Unidirectional shunt TVS placed between high-side switch drain and ground, clamping transients within 1 ns. Use Value: Limits voltage overshoot to ≤159 V, preventing gate oxide rupture in 100 V-rated MOSFETs and maintaining signal integrity in isolated current sense amplifiers. | Use Scenario: Surge suppression on -48 V DC telecom power distribution lines exposed to lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Standoff-rated TVS connected between power rail and chassis ground, absorbing differential-mode transients up to 600 W. Use Value: Maintains <0.5 μA leakage at nominal -48 V, minimizing standby power loss while clamping induced spikes to safe levels for downstream DC/DC converters. |
| Automotive Body Control Modules | Industrial PLC I/O Protection |
Use Scenario: Input protection for LIN bus transceivers and microcontroller GPIOs subjected to load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS installed on each 12 V supply rail feeding microcontroller peripherals, referenced to local ground plane. Use Value: Withstands 150 °C junction temperature and clamps 3.77 A pulses to 159 V, preserving MCU functionality during ISO 16750-2 pulse 5a events. | Use Scenario: Protection of analog input channels (0–10 V, 4–20 mA) in programmable logic controllers interfacing with field sensors. IC Role / Device Role / Timing Role: High-VWM TVS placed at terminal block entry point, shunting fast transients before they reach precision op-amp front-ends. Use Value: 100 V standoff avoids false triggering during normal operation; 159 V clamping prevents ADC saturation and maintains measurement accuracy during EFT bursts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A-M3/I | Bidirectional variant; same VWM (100 V), but symmetric clamping in both polarities | Required where AC-coupled or dual-polarity signal lines need protection (e.g., RS-485, CAN bus) | Select SMBJ100A-M3/I only if bidirectional clamping is required; SMBJ100D-M3/I is optimal for DC power rail protection. |
| SMCJ100A-M3 | Larger SMC (DO-214AB) package; higher 1500 W PPPM rating; same 100 V VWM and 159 V VC | Used where higher surge energy handling is needed (e.g., outdoor power supplies, solar inverters) | Choose SMCJ100A-M3 when board space allows and surge duty exceeds 600 W; SMBJ100D-M3/I fits tighter layouts with adequate 600 W rating. |
Compared with SMBJ100A-M3/I, SMBJ100D-M3/I provides superior DC rail protection due to unidirectional architecture and lower leakage; versus SMCJ100A-M3, it trades surge capacity for compact SMB footprint-critical for space-constrained industrial control modules.
