Product details
Overview
SMBJ60CD-M3/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 60 V standoff voltage (VWM), 67.7–72.7 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), and clamps to ≤95.5 V at 6.28 A surge current - used in industrial sensor interfaces and telecom line protection.
For engineers reviewing the SMBJ60CD-M3/I datasheet, SMBJ60CD-M3/I pinout, SMBJ60CD-M3/I application, or SMBJ60CD-M3/I equivalent, key selection criteria include bidirectional clamping capability, ±3.5% VBR tolerance, MSL Level 1 moisture sensitivity, halogen-free RoHS-compliant construction, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche behavior in both polarities, enabling suppression of positive and negative transients without polarity dependency. Its low incremental surge resistance and fast response time ensure effective protection against ESD, lightning-induced surges, and inductive switching spikes.
The SMBJ60CD-M3/I is rated for 150 °C maximum junction temperature and derates linearly above 25 °C ambient, with thermal resistance RθJA = 125 °C/W on minimum recommended pad layout. It meets UL 497B recognition (QVGQ2) and complies with JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 67.7 V / 72.7 V at 1 mA - tight ±3.5% tolerance ensures predictable turn-on across production lots |
| VC @ IPPM | ≤95.5 V at 6.28 A - clamping voltage limits downstream IC stress during 10/1000 μs surge events |
| PPPM | 600 W - peak pulse power handling per 10/1000 μs waveform, supporting IEC 61000-4-5 Level 4 compliance |
| ID @ VWM | ≤0.5 μA - ultra-low leakage preserves signal integrity in high-impedance sensor or data lines |
| TJ max | 150 °C - enables reliable operation in industrial environments with elevated ambient temperatures |

Pinout & Package
Two-terminal bidirectional device in SMB (DO-214AA) package; no polarity marking - terminals are symmetric and interchangeable. Matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 reliability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (both) | Surge current path | Identical terminal function in either direction - enables single-component protection of AC-coupled or differential signal lines |
| Case | Thermal path | Exposed cathode-side metal tab (per DO-214AA) provides primary heat conduction to PCB copper area |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, RS-485 buses, or transformer-coupled interfaces without external polarity management |
| ±3.5% VBR tolerance | Reduces design margin overhead and allows tighter system-level voltage window allocation versus looser-tolerance TVS devices |
| MSL Level 1 rating | Permits unlimited floor life and reflow at 260 °C peak without baking - simplifies manufacturing logistics |
| Halogen-free & RoHS | Meets IPC-1752A material declaration requirements and supports green electronics compliance programs |
| 600 W surge rating | Supports robust protection against 1 kV/500 A combination wave (IEC 61000-4-5) on 50 Ω source impedance lines |
Applications
| Industrial Sensor Interface | Telecom Line Protection |
|---|---|
Use Scenario: Protecting analog output (4–20 mA) or digital (RS-485) sensor outputs from field-induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: Voltage-clamping transient suppressor placed directly at connector entry point, shunting surge energy to ground before reaching precision ADC or transceiver IC. Use Value: Limits transient voltage to ≤95.5 V, preventing latch-up or gate oxide damage in connected microcontrollers and interface ICs under IEC 61000-4-4/5 stress. | Use Scenario: Shielding Ethernet PHY or DSL line drivers from lightning-induced common-mode surges on outdoor-facing telecom ports. IC Role / Device Role / Timing Role: Bidirectional clamping element across differential pair (e.g., TX+/TX−), referenced to chassis ground via low-inductance path. Use Value: Symmetric clamping ensures equal protection for both polarities of fast-rising transients, maintaining signal integrity without DC bias shift. |
| Consumer Power Adapter Input | Automotive Body Control Module |
Use Scenario: Secondary-side overvoltage suppression on 12 V DC input rails of USB-C PD adapters after rectification and filtering. IC Role / Device Role / Timing Role: Standoff-rated TVS placed between VIN and GND to clamp switching spikes from flyback transformer leakage inductance. Use Value: 60 V VWM aligns with 12 V nominal + 40 % tolerance (16.8 V) plus worst-case surge overshoot, avoiding false triggering during normal operation. | Use Scenario: Protecting LIN bus transceivers and microcontroller GPIOs from load-dump and jump-start transients in vehicle door modules. IC Role / Device Role / Timing Role: Bidirectional suppressor across LIN signal and ground, mounted near connector to minimize trace inductance. Use Value: Withstands repetitive 12 V system surges up to 600 W peak, meeting ISO 7637-2 Pulse 1/2a/5a immunity requirements without derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA-E3/52 (Vishay) | Same electrical specs and SMB package; differs only in tape-and-reel packaging (52 = 3200 pcs/reel, same as -M3/I) and RoHS status (E3 = lead-free, M3 = halogen-free + RoHS) | No functional difference - identical clamping performance and thermal behavior in circuit | Select SMBJ60CD-M3/I when halogen-free compliance is required per IPC-1752A; otherwise SMBJ60CA-E3/52 is functionally interchangeable |
| 1.5SMC60CA (ON Semiconductor) | Same VWM (60 V), bidirectional, 600 W rating, but in larger SMC (DO-214AB) package (7.11 mm × 6.22 mm vs. SMB's 5.59 mm × 3.94 mm) | Requires PCB layout change due to larger footprint and higher thermal mass; slightly lower clamping ratio (VC/VBR ≈ 1.41 vs. 1.40) | Choose only if existing design uses SMC footprint or requires higher thermal dissipation margin; not drop-in compatible with SMBJ60CD-M3/I layout |
Compared with SMBJ60CA-E3/52, the SMBJ60CD-M3/I offers identical protection performance with certified halogen-free construction; versus 1.5SMC60CA, it delivers equivalent surge capability in a 40 % smaller footprint but requires verification of thermal performance under sustained surge duty cycles.

FAQ
What is the standoff voltage rating of SMBJ60CD-M3/I?
The SMBJ60CD-M3/I has a maximum reverse standoff voltage (VWM) of 60 V. This means it remains non-conductive under continuous DC or AC voltages up to 60 V, making it suitable for protecting 48 VDC industrial buses or 24 VAC control lines without leakage-related power loss or false triggering.
Is SMBJ60CD-M3/I unidirectional or bidirectional?
SMBJ60CD-M3/I is a bidirectional transient voltage suppressor, indicated by the "CD" suffix. It provides symmetrical clamping for both positive and negative transients, eliminating the need for polarity-aware placement - ideal for AC-coupled data lines like RS-485 or CAN FD physical layers.
What does the "M3" suffix mean in SMBJ60CD-M3/I?
The "M3" suffix in SMBJ60CD-M3/I denotes halogen-free, RoHS-compliant construction with matte tin-plated leads that pass JESD201 Class 2 whisker testing. It also specifies industrial-grade reliability and compliance with UL 94 V-0 flammability rating for the molding compound.
Can SMBJ60CD-M3/I be used in place of a unidirectional SMBJ60D-M3/I?
No - SMBJ60CD-M3/I is bidirectional and lacks a cathode band, while SMBJ60D-M3/I is unidirectional with defined anode/cathode polarity. Substituting them requires verifying circuit topology: bidirectional use cases (e.g., differential signaling) require SMBJ60CD-M3/I; DC-biased rails require SMBJ60D-M3/I. Their VBR and VC values differ slightly due to test condition variations.
What is the maximum clamping voltage for SMBJ60CD-M3/I at its rated surge current?
The SMBJ60CD-M3/I clamps to a maximum of 95.5 V at its peak pulse current (IPPM) of 6.28 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
