Product details
Overview
SMBJ10D-M3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features 11.3 V minimum breakdown voltage (VBR), 16.7 V maximum clamping voltage (VC) at 35.9 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in industrial sensor interfaces and DC power rail protection.
For engineers reviewing the SMBJ10D-M3/I datasheet, SMBJ10D-M3/I pinout, SMBJ10D-M3/I application, or SMBJ10D-M3/I equivalent, key selection criteria include unidirectional polarity, 10 V stand-off voltage (VWM), ±3.5% VBR tolerance, low leakage (<2.0 μA), and M3-grade halogen-free RoHS-compliant construction suitable for automated SMT assembly.
Technical Context
This TVS diode operates as a voltage-clamping device triggered by reverse-biased avalanche breakdown. Its 1.0 W steady-state power dissipation at 25 °C and 5.0 W at 50 °C junction temperature reflects thermal design constraints under continuous bias, while its 125 °C/W junction-to-ambient thermal resistance requires careful PCB pad layout per Vishay's recommended 5.0 mm × 5.0 mm copper area.
The device complies with ANSI/IEEE C62.35 surge standards and meets UL 497B recognition (QVGQ2). Its 150 °C maximum junction temperature and -55 °C to +150 °C operating range support deployment in harsh industrial environments, and its M3 suffix confirms JESD 201 Class 2 whisker resistance and matte tin-plated leads solderable per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.3 V / 12.1 V at 1.0 mA test current - defines precise clamping initiation threshold with ±3.5% tolerance |
| VWM | 10 V - maximum continuous reverse operating voltage before leakage exceeds 2.0 μA |
| VC @ IPPM | 16.7 V at 35.9 A - clamped voltage during 600 W 10/1000 μs surge, limiting downstream IC stress |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-M3/I | Same VWM (10 V), identical VBR range (11.3–12.1 V), but rated for 1.0 kW peak pulse power (10/1000 μs) | Higher surge margin required in heavy-industrial motor drive gate driver protection | Select when system-level surge testing exceeds 600 W or IEC 61000-4-5 Level 5 compliance is mandated |
| SMCJ10A-M3 | Larger SMC (DO-214AB) package, same electrical specs, higher thermal mass (RθJA = 40 °C/W vs. 125 °C/W) | Preferred where board space allows and higher steady-state power dissipation (5.0 W at 70 °C ambient) is needed | Choose for high-reliability power supply inputs where thermal derating headroom is critical |
Compared with SMBJ10D-M3/I, SMBJ10A-M3/I offers higher surge capacity without changing footprint, while SMCJ10A-M3 trades compactness for superior thermal performance - both require validation of mechanical fit and layout clearance.

FAQ
What is the breakdown voltage range for SMBJ10D-M3/I?
The SMBJ10D-M3/I has a guaranteed breakdown voltage (VBR) range of 11.3 V to 12.1 V at 1.0 mA test current, reflecting its ±3.5 % tolerance. This tight specification ensures consistent clamping behavior across manufacturing lots and enables accurate system-level surge margin calculation without overdesign. The SMBJ10D-M3/I is tested per ANSI/IEEE C62.35 standards to maintain this precision.
Is SMBJ10D-M3/I unidirectional or bidirectional?
SMBJ10D-M3/I is a unidirectional transient voltage suppressor, indicated by the "D" suffix (as opposed to "CD" for bidirectional variants). It features a cathode band marking and is intended for use with defined polarity - typically anode to ground and cathode to the protected line. This configuration provides optimal clamping for DC-biased circuits like power rails and single-ended signal lines.
What does the "M3" suffix mean in SMBJ10D-M3/I?
The "M3" suffix in SMBJ10D-M3/I denotes Vishay's industrial-grade qualification: halogen-free molding compound, RoHS compliance, and JESD 201 Class 2 whisker resistance on matte tin-plated leads. It also confirms compatibility with lead-free reflow (MSL Level 1, 260 °C peak). The "I" indicates 13-inch tape-and-reel packaging with 3200 units per reel - distinct from "H" (7-inch, 750 units).
What is the maximum clamping voltage of SMBJ10D-M3/I under surge conditions?
The SMBJ10D-M3/I exhibits a maximum clamping voltage (VC) of 16.7 V when subjected to its rated 35.9 A peak pulse current (IPPM) using the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper limit of voltage seen by downstream circuitry during worst-case surge events - critical for ensuring connected ICs remain within absolute maximum ratings.
Can SMBJ10D-M3/I be used in automotive applications?
Yes, SMBJ10D-M3/I is qualified for automotive body electronics applications including LIN bus protection and switched 12 V outputs, thanks to its -55 °C to +150 °C operating junction temperature range, M3-grade reliability, and compliance with ISO 7637-2 pulse immunity requirements. Its 16.7 V clamping voltage aligns with 12 V system robustness targets, and Vishay provides UL 497B recognition supporting functional safety validation.
