Product details
Overview
SMBJ110D-M3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 110 V stand-off voltage (VWM), 124–133 V breakdown voltage (VBR) at 1 mA, 174 V maximum clamping voltage (VC) at 3.45 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 industrial power supplies.
For engineers reviewing the SMBJ110D-M3/H datasheet, SMBJ110D-M3/H pinout, SMBJ110D-M3/H application, or SMBJ110D-M3/H equivalent, key selection criteria include unidirectional polarity, ±3.5% VBR tolerance, low leakage (<0.5 μA at VWM), M3 halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This TVS diode operates as a voltage-clamping protection device triggered by overvoltage events such as inductive load switching or ESD. Its silicon avalanche structure provides sub-nanosecond response time and low incremental surge resistance, enabling effective suppression of transients before downstream components are damaged.
The SMBJ110D-M3/H is rated for 150 °C maximum junction temperature, meets MSL level 1 per J-STD-020 (peak reflow 260 °C), and delivers 1.0 W steady-state power dissipation at 25 °C ambient - derated linearly above that temperature per published thermal curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 110 V - maximum continuous reverse operating voltage before conduction begins |
| VBR min/max | 124 V / 133 V at 1 mA - tight ±3.5% tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | 174 V at 3.45 A - clamping voltage limits stress on protected circuitry during 10/1000 μs surge |
| PPPM | 600 W - peak pulse power handling capability under standardized transient waveform |
| ID @ VWM | <0.5 μA - minimal leakage preserves efficiency in high-impedance or battery-powered circuits |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 5.59 mm × 3.94 mm footprint and 2.20 mm height |
| TJ max | 150 °C - enables reliable operation in industrial and automotive under-hood environments |
Pinout & Package
Two-terminal unidirectional TVS diode in SMB (DO-214AA) package. Cathode indicated by molded band on case; anode is opposite end. Matte tin-plated leads meet J-STD-002 solderability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased terminal during normal operation | Connects to protected line; conducts when transient exceeds VBR, shunting current to ground |
| Anode (unbanded end) | Reference/ground return path | Typically tied to system ground or low-impedance return plane to complete clamping path |
Key Features
| Feature | Design Value |
|---|---|
| ±3.5 % VBR tolerance | Enables precise coordination with system overvoltage thresholds without margin stacking |
| 600 W peak pulse power (10/1000 μs) | Handles common lightning-induced surges and inductive kickback in 24 V/48 V industrial systems |
| Low 0.5 μA max leakage at VWM | Minimizes standby power loss in always-on sensor nodes and battery-backed control modules |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free reflow assembly without preconditioning or special handling |
| M3 suffix compliance | Halogen-free, RoHS-compliant, and JESD 201 Class 2 whisker-resistant for long-term reliability |
Applications
| Industrial Motor Drives | Telecom Power Supplies |
|---|---|
Use Scenario: Protection of gate drivers and bus voltage sense circuits against flyback transients from IGBT/MOSFET switching. IC Role / Device Role / Timing Role: Unidirectional clamping diode placed across DC bus or gate-source terminals to limit voltage overshoot. Use Value: Prevents destructive overvoltage on sensitive gate oxide layers and analog front-end components during rapid current interruption. | Use Scenario: Input-stage surge protection on 48 V telecom rectifier outputs exposed to lightning-induced surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Primary transient suppressor located at board edge before DC-DC converters and PMICs. Use Value: Clamps 174 V at 3.45 A to keep downstream regulators within safe operating area during 600 W surge events. |
| Automotive Body Control Modules | Industrial Sensor Signal Conditioning |
Use Scenario: Protection of LIN/CAN transceiver power rails against load dump and jump-start transients. IC Role / Device Role / Timing Role: Standoff-rated TVS on 12 V supply rail upstream of LDOs and interface ICs. Use Value: Maintains 110 V standoff while clamping to 174 V - compatible with ISO 16750-2 load dump profile up to 120 V. | Use Scenario: Protection of analog inputs (e.g., 4–20 mA loop receivers, thermocouple amplifiers) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-leakage unidirectional TVS placed between signal line and ground reference. Use Value: Sub-μA leakage avoids gain error in precision instrumentation; fast response prevents latch-up in op-amps and ADCs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-M3/H | Bidirectional variant with same VWM (110 V), but symmetric clamping in both polarities | Required where AC-coupled or floating signal lines need protection from bipolar transients | Select SMBJ110A-M3/H only if bidirectional clamping is explicitly needed; SMBJ110D-M3/H is optimal for DC rail protection. |
| SMCJ110A | Larger SMC (DO-214AB) package, higher 1500 W PPPM rating, same VWM/VBR range | Used where higher surge energy handling or improved thermal dissipation is required | Choose SMCJ110A when system-level surge testing exceeds 600 W or board layout allows larger footprint. |
Compared with SMBJ110A-M3/H and SMCJ110A, the SMBJ110D-M3/H offers tighter VBR tolerance and smaller SMB footprint ideal for space-constrained DC power rail protection - while maintaining full compatibility with automated SMT assembly and industrial temperature requirements.

FAQ
What is the maximum clamping voltage of SMBJ110D-M3/H at its rated peak pulse current?
The SMBJ110D-M3/H has a maximum clamping voltage (VC) of 174 V at its specified peak pulse current (IPPM) of 3.45 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 standards and defines the upper voltage limit imposed on protected circuitry during surge events - ensuring downstream components remain within safe operating voltage ranges.
Is SMBJ110D-M3/H suitable for protecting 48 V telecom power rails?
Yes, SMBJ110D-M3/H is suitable for protecting 48 V telecom power rails. With a 110 V stand-off voltage (VWM), it remains non-conductive during normal operation and reliably clamps transients up to 174 V. Its 600 W peak pulse rating aligns with IEC 61000-4-5 Level 3/4 surge requirements commonly applied to telecom infrastructure equipment.
Does SMBJ110D-M3/H have RoHS and halogen-free compliance?
Yes, SMBJ110D-M3/H carries the M3 suffix, indicating full compliance with RoHS directives and halogen-free construction per IEC 61249-2-21. It also passes JESD 201 Class 2 whisker testing and meets UL 94 V-0 flammability requirements for the molding compound - confirming suitability for environmentally regulated industrial and consumer applications.
What is the thermal resistance junction-to-ambient for SMBJ110D-M3/H?
The typical thermal resistance junction-to-ambient (RθJA) for SMBJ110D-M3/H is 125 °C/W when mounted on the minimum recommended PCB pad layout, and 100 °C/W on a 5.0 mm × 5.0 mm copper pad. These values inform thermal design margins - for example, at 1.0 W steady-state dissipation, junction temperature rise above ambient is ~125 °C on minimal pads, necessitating layout-aware derating in enclosed or high-temperature environments.
How does the ±3.5 % VBR tolerance of SMBJ110D-M3/H impact system-level protection design?
The ±3.5 % VBR tolerance of SMBJ110D-M3/H (124–133 V at 1 mA) enables precise coordination with system overvoltage protection thresholds without excessive design margin. This tight distribution reduces risk of premature clamping or delayed response, improving reliability in applications like industrial PLC I/O modules where consistent trip points across production units are essential for certification and field performance.
