Product details
Overview
SMBJ10CD-M3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 10 V stand-off voltage (VWM), 11.3–12.1 V breakdown voltage (VBR) at 1 mA test current, 16.7 V maximum clamping voltage (VC) at 35.9 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and industrial I/O lines.
For engineers reviewing the SMBJ10CD-M3/H datasheet, SMBJ10CD-M3/H pinout, SMBJ10CD-M3/H application, or SMBJ10CD-M3/H equivalent, key selection criteria include bidirectional clamping capability, ±3.5 % VBR tolerance, low leakage (<2.0 μA at VWM), MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction suitable for automated SMT assembly.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical avalanche behavior in both polarities, enabling robust protection of AC-coupled or floating signal paths without polarity concerns. Its low incremental surge resistance and fast response time ensure effective suppression of ESD, lightning-induced surges, and inductive switching spikes.
The SMBJ10CD-M3/H is rated for 150 °C maximum junction temperature and exhibits thermal resistance of 125 °C/W (junction-to-ambient, mounted on minimum pad layout) and 20 °C/W (junction-to-mount), supporting reliable operation under repetitive surge conditions when properly heatsinked.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum reverse stand-off voltage before significant conduction begins; defines safe operating range for protected circuitry. |
| VBR min/max | 11.3 V / 12.1 V at 1 mA - tight ±3.5 % tolerance ensures predictable turn-on across production lots. |
| VC @ IPPM | 16.7 V at 35.9 A - clamping voltage during 10/1000 μs surge; limits stress on downstream components. |
| PPPM | 600 W - peak pulse power handling per single 10/1000 μs transient; supports high-energy surge immunity. |
| ID @ VWM | <2.0 μA - ultra-low reverse leakage preserves signal integrity and minimizes standby power loss. |
| TJ max | 150 °C - enables deployment in industrial environments with elevated ambient temperatures. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and MSL Level 1 rating. |
Pinout & Package
Package: SMB (DO-214AA), bidirectional configuration with no cathode band marking; terminals are matte tin-plated for solderability per J-STD-002 and JESD 22-B102, and qualified to JESD 201 Class 2 whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; voltage clamping occurs regardless of polarity - eliminates orientation constraints during placement. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC signals, differential buses, and floating nodes without polarity-sensitive layout. |
| ±3.5 % VBR tolerance | Reduces design margin requirements and improves consistency in multi-channel protection schemes. |
| 600 W peak pulse power | Meets IEC 61000-4-5 Level 4 surge immunity (4 kV line-to-line) with appropriate PCB layout. |
| MSL Level 1 rating | Allows unlimited floor life and reflow compatibility up to 260 °C peak without baking preconditioning. |
| Halogen-free & RoHS | Complies with environmental regulations and supports lead-free manufacturing processes. |
Applications
| Industrial Sensor Interface | RS-485 Communication Line |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors exposed to motor drive noise and relay switching transients in factory automation cabinets. IC Role / Device Role / Timing Role: Bidirectional TVS diode placed across signal and return lines to clamp common-mode and differential surges before they reach ADC input stages. Use Value: Prevents sensor output saturation or latch-up during 1 kV/μs fast transients while maintaining sub-μA leakage for precision measurement accuracy. |
Use Scenario: Safeguarding RS-485 transceivers connected to long cable runs in building control systems subject to lightning-induced ground potential differences. IC Role / Device Role / Timing Role: Differential-line TVS placed between A/B bus lines and ground to suppress common-mode surges without distorting data eye integrity. Use Value: Limits clamping voltage to 16.7 V during 35.9 A surges, keeping transceiver inputs within absolute maximum ratings and avoiding data corruption. |
| Power Supply Input Stage | Automotive Body Control Module I/O |
Use Scenario: Secondary overvoltage protection on 12 V DC input rails after primary fuse and filter stage in embedded controllers. IC Role / Device Role / Timing Role: Fast-acting shunt device that activates within nanoseconds to divert surge energy away from LDO regulators and microcontroller power pins. Use Value: Withstands 600 W pulses without degradation, ensuring sustained reliability across repeated load-dump events per ISO 7637-2 Pulse 5a. |
Use Scenario: Protecting GPIO lines driving relays and LEDs in automotive BCMs exposed to battery disconnect transients and alternator load dump. IC Role / Device Role / Timing Role: Bidirectional clamp on switched 12 V outputs to absorb reverse EMF from inductive loads and prevent MCU port damage. Use Value: Low 2.0 μA leakage at 10 V stand-off avoids excessive quiescent current draw in always-on vehicle modules. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10CA-E3/52 (Vishay) | Same VWM/VBR/VC specs; differs in packaging (tape-and-reel quantity and reel diameter) and M3 vs. standard termination qualification. | No functional difference in circuit protection performance; identical electrical behavior and thermal derating. | Select SMBJ10CD-M3/H for halogen-free, industrial-grade, whisker-tested supply chain continuity. |
| 1.5SMC10CA (ON Semiconductor) | Same 10 V bidirectional rating but in larger SMC (DO-214AB) package; higher RθJA (100 °C/W vs. 125 °C/W) and 1.5 kW PPPM rating. | Requires larger PCB area; better suited for higher average power dissipation but less space-efficient than SMBJ10CD-M3/H. | Choose SMBJ10CD-M3/H where board space is constrained and MSL Level 1 reflow compatibility is required. |
Compared with SMBJ10CA-E3/52, SMBJ10CD-M3/H offers enhanced process control for industrial reliability; versus 1.5SMC10CA, it trades peak power headroom for compact SMB footprint and tighter assembly compatibility.

FAQ
What does the "CD" suffix indicate in SMBJ10CD-M3/H?
The "CD" suffix denotes a bidirectional configuration - meaning SMBJ10CD-M3/H provides symmetrical clamping in both polarities, with no cathode marking and identical VBR/VWM characteristics for positive and negative voltage excursions. This makes SMBJ10CD-M3/H ideal for protecting AC signals, differential buses, or floating nodes where polarity cannot be guaranteed.
Is SMBJ10CD-M3/H compatible with lead-free reflow processes?
Yes, SMBJ10CD-M3/H is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated terminals meet J-STD-002 solderability requirements, and the M3 suffix confirms qualification to JESD 201 Class 2 whisker testing - making SMBJ10CD-M3/H fully suitable for standard lead-free SMT assembly without preconditioning.
How does SMBJ10CD-M3/H differ from unidirectional SMBJ10D-M3/H?
SMBJ10CD-M3/H has identical VWM (10 V), VBR (11.3–12.1 V), and VC (16.7 V) ratings as SMBJ10D-M3/H but operates bidirectionally - with no cathode band and symmetrical conduction. Unidirectional SMBJ10D-M3/H requires correct polarity alignment and clamps only in reverse bias; SMBJ10CD-M3/H eliminates orientation dependency and protects against both positive and negative transients equally.
What is the maximum allowable surge current for SMBJ10CD-M3/H?
The maximum peak pulse current (IPPM) for SMBJ10CD-M3/H is 35.9 A under the standard 10/1000 μs double-exponential waveform. This value is derived directly from its 600 W PPPM rating and 16.7 V clamping voltage (IPPM = PPPM / VC). Derating applies above TA = 25 °C per Figure 2 in the Vishay datasheet 87606.
Does SMBJ10CD-M3/H meet UL recognition standards?
Yes, SMBJ10CD-M3/H carries Underwriters Laboratory Recognition under UL 497B (QVGQ2 file E136766) for both unidirectional and bidirectional transient protectors. This certification validates its safety performance in telecommunications and industrial equipment applications where regulatory compliance is mandatory.
