Product details
Overview
SMBJ10CD-M3/I from Vishay General Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 10 V standoff voltage (VWM), 11.3–12.1 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), and clamps to ≤16.7 V at 35.9 A peak surge current - used to protect MOSFETs and sensor interfaces in industrial control systems.
For engineers reviewing the SMBJ10CD-M3/I datasheet, SMBJ10CD-M3/I pinout, SMBJ10CD-M3/I application, or SMBJ10CD-M3/I equivalent, key selection criteria include bidirectional clamping capability, ±3.5% VBR tolerance, M3 halogen-free RoHS-compliant construction, low leakage (<2.0 μA at VWM), and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamping protection element in both polarities, leveraging avalanche breakdown to divert transient energy away from downstream circuitry. Its bidirectional symmetry ensures identical electrical characteristics in forward and reverse directions, eliminating polarity concerns during layout.
Designed for transient suppression per IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge), it delivers fast response time (<1 ns), low clamping ratio (VC/VBR ≈ 1.45), and thermal stability up to TJ = 150 °C with RθJA = 125 °C/W on minimum recommended pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before significant leakage begins |
| 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 limits stress on protected ICs during 600 W transient events |
| PPPM | 600 W (10/1000 μs waveform) - defines surge handling capacity under standardized lightning/surge test conditions |
| ID @ VWM | ≤2.0 μA - ultra-low leakage preserves signal integrity and battery life in always-on circuits |
| TJ max | 150 °C - enables reliable operation in high-temperature industrial environments without derating |
| Package | SMB (DO-214AA) - industry-standard 2-pin SMD outline compatible with JEDEC MS-012AC footprint |
Pinout & Package
Two-terminal device in SMB (DO-214AA) package; no polarity marking for bidirectional operation. Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, with M3 suffix indicating halogen-free, RoHS-compliant, and JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal serves as input/output - no orientation required during placement |
| Cathode band (absent) | Polarity indicator | Not present - confirms bidirectional functionality; eliminates risk of incorrect orientation |
Key Features
| Feature | Design Value |
|---|---|
| ±3.5 % VBR tolerance | Enables precise, repeatable clamping thresholds across temperature and lot variations |
| 600 W peak pulse power | Supports robust protection against IEC 61000-4-5 Level 4 (4 kV line-to-line) surges |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ESD, inductive kick) |
| MSL Level 1 (260 °C peak) | Allows single-reflow assembly without moisture sensitivity concerns or baking requirements |
| Halogen-free, RoHS-compliant (M3) | Meets environmental compliance mandates for industrial and telecom equipment globally |
Applications
| Industrial Motor Control | Automotive Sensor Interface |

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/PPPM specs; E3/52 denotes tape-and-reel packaging per older standard, no M3 halogen-free assurance | Lacks JESD 201 Class 2 whisker resistance and explicit halogen-free certification | Select SMBJ10CD-M3/I when RoHS/halogen-free compliance and long-term reliability in high-humidity environments are mandatory |
| 1.5SMC10CA (ON Semiconductor) | Same 10 V bidirectional rating but in larger SMC (DO-214AB) package; 600 W rating, slightly higher VC (17.0 V) | Requires larger PCB footprint and has higher thermal resistance (RθJA ≈ 140 °C/W) | Choose SMBJ10CD-M3/I for space-constrained designs needing SMB footprint and lower thermal impedance |
Compared with SMBJ10CA-E3/52 and 1.5SMC10CA, the SMBJ10CD-M3/I provides verified halogen-free construction, tighter process control for VBR consistency, and optimized thermal performance in the smaller SMB outline - making it preferred for modern industrial and automotive BOMs requiring full material compliance and layout efficiency.

FAQ
What does the "CD" suffix mean in SMBJ10CD-M3/I?
The "CD" suffix in SMBJ10CD-M3/I indicates a bidirectional configuration - meaning the device provides symmetrical transient suppression in both polarities, with identical VBR, VC, and IPPM values in either direction. This eliminates polarity marking and simplifies PCB layout compared to unidirectional variants like SMBJ10D-M3/I.
Is SMBJ10CD-M3/I suitable for IEC 61000-4-5 surge protection?
Yes, SMBJ10CD-M3/I is rated for 600 W peak pulse power with a 10/1000 μs waveform, aligning with IEC 61000-4-5 Level 4 (4 kV line-to-line) testing conditions. Its 16.7 V clamping voltage at 35.9 A ensures downstream components remain within safe operating limits during standardized surge events.
What is the significance of the "M3" suffix in SMBJ10CD-M3/I?
The "M3" suffix in SMBJ10CD-M3/I certifies halogen-free, RoHS-compliant construction and compliance with JESD 201 Class 2 whisker resistance testing. It also denotes industrial-grade qualification, including MSL Level 1 moisture sensitivity and 260 °C reflow compatibility - critical for high-reliability manufacturing.
How does SMBJ10CD-M3/I compare to unidirectional SMBJ10D-M3/I in circuit design?
SMBJ10CD-M3/I replaces SMBJ10D-M3/I only where bidirectional clamping is required - such as across differential lines or AC-coupled signals. Unlike SMBJ10D-M3/I, it lacks a cathode band and must not be substituted in unidirectional DC rail protection without verifying system-level polarity constraints and leakage behavior.
What PCB pad layout is recommended for optimal thermal performance of SMBJ10CD-M3/I?
Vishay specifies a minimum 5.0 mm × 5.0 mm copper pad area per terminal for SMBJ10CD-M3/I to achieve RθJA = 100 °C/W. Using the standard SMB footprint with extended thermal pads significantly improves power dissipation capability beyond the 125 °C/W value measured on minimal pads - essential for repeated surge events.
