Product details
Overview
SMBJ60CD-M3/H 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 60 V stand-off 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 - ideal for protecting I/O ports and sensor interfaces in industrial control systems.
For engineers reviewing the SMBJ60CD-M3/H datasheet, SMBJ60CD-M3/H pinout, SMBJ60CD-M3/H application, or SMBJ60CD-M3/H equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal derating curves, M3 halogen-free RoHS-compliant construction, and real-world protection use cases - all critical for ESD/surge co-design with microcontrollers, RS-485 transceivers, and automotive body electronics.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling robust protection of AC-coupled or differential signal paths without polarity constraints. Its low incremental surge resistance and fast response time (<1 ns) ensure minimal let-through energy during lightning-induced or inductive-switching transients.
The device complies with UL 497B recognition (QVGQ2) and meets JESD201 Class 2 whisker resistance. With a junction temperature range of –55 °C to +150 °C and MSL Level 1 moisture sensitivity, it supports reflow soldering up to 260 °C peak and long-term reliability in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 48 V DC bus or 36 V nominal systems |
| 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 600 W 10/1000 μs surge events |
| PPPM | 600 W - peak pulse power rating per standard 10/1000 μs waveform; validated for repetitive 0.01 % duty cycle |
| ID @ VWM | ≤0.5 μA - ultra-low leakage preserves signal integrity and battery life in always-on sensor nodes |
| TJ max | +150 °C - enables operation in under-hood automotive or enclosed industrial enclosures without forced cooling |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant, matte tin-plated terminals, MSL Level 1, 260 °C reflow compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Cathode Band Absent) | Terminal A | Bidirectional symmetry - no polarity marking; either terminal serves as anode or cathode depending on transient polarity |
| Cathode (Cathode Band Absent) | Terminal B | Identical to Terminal A - dual-symmetry design eliminates orientation concerns during automated placement |
Key Features
| Feature | Design Value |

Applications
| Industrial Sensor Interface Protection | Automotive Body Control Module I/O |
|---|---|
Use Scenario: Protecting analog inputs of PLC analog input modules from inductive kickback during solenoid switching in factory automation. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point, shunting transients before reaching op-amp front-end or ADC driver. Use Value: Limits voltage excursion to ≤95.5 V during 600 W surges, preventing latch-up or permanent damage to 12-bit SAR ADCs rated for 5.5 V absolute max input. | Use Scenario: Safeguarding LIN bus transceiver pins against load dump and jump-start transients in door module ECUs. IC Role / Device Role / Timing Role: Standoff-clamp TVS located between LIN PHY and connector, operating symmetrically to handle both positive and negative polarity spikes. Use Value: Maintains <0.5 μA leakage at 12 V nominal, preserving bus idle voltage stability while clamping 100 V transients within 1 ns. |
| RS-485 Transceiver Port Protection | Consumer Appliance Motor Drive Feedback Lines |
Use Scenario: Shielding half-duplex RS-485 transceivers (e.g., MAX13487) in building automation gateways from EFT and surge coupling via shared cabling. IC Role / Device Role / Timing Role: Differential-line TVS pair (one per A/B line) referenced to ground, leveraging bidirectional symmetry to protect against common-mode surges. Use Value: Clamps 6.28 A surge to ≤95.5 V, keeping transceiver differential input voltage within ±12 V common-mode range and avoiding receiver saturation. | Use Scenario: Securing hall-effect rotor position feedback signals from BLDC motor drivers in smart washing machines exposed to brush-commutator noise. IC Role / Device Role / Timing Role: Point-of-entry TVS on 5 V encoder supply and signal lines, placed before level-shifter ICs feeding MCU GPIOs. Use Value: Delivers <1 ns response and ≤0.5 μA leakage, ensuring clean 5 V logic levels and preventing false edge detection during high-dV/dt commutation events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA-E3/52 (Vishay) | Same VWM/VBR/PPPM specs; differs only in packaging (tape-and-reel vs. bulk) and JEDEC compliance code (E3/52 vs. M3/H) | No functional difference - identical electrical and thermal performance; E3/52 used in legacy designs with different logistics requirements | Select SMBJ60CD-M3/H for new designs requiring halogen-free, RoHS-compliant, whisker-resistant construction per JESD201 Class 2 |
| 1.5SMC60CA (ON Semiconductor) | Same SMB package and bidirectional 60 V rating, but wider VBR tolerance (±5 %), higher ID (1.0 μA), and lower thermal resistance (RθJA = 100 °C/W vs. 125 °C/W) | Better suited for high-temperature ambient applications where thermal margin is constrained; slightly looser VBR may require larger system guard bands | Choose 1.5SMC60CA only if board-level thermal management exceeds minimum pad layout and tighter VBR tolerance is not required |
Compared with SMBJ60CD-M3/H, SMBJ60CA-E3/52 offers identical protection performance with alternate packaging logistics, while 1.5SMC60CA trades tighter VBR control for improved thermal dissipation - making SMBJ60CD-M3/H optimal for precision clamping in space-constrained, high-reliability industrial layouts.

FAQ
What does the "CD" suffix indicate in SMBJ60CD-M3/H?
The "CD" suffix in SMBJ60CD-M3/H denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., SMBJ60D), SMBJ60CD-M3/H has no cathode band and functions identically regardless of polarity - essential for protecting AC-coupled lines, differential buses like RS-485, or floating sensor outputs where voltage reversals occur.
Does SMBJ60CD-M3/H meet UL 497B recognition?
Yes, SMBJ60CD-M3/H is UL 497B recognized under file number E136766 for both unidirectional and bidirectional configurations. This certification confirms its suitability for use as a primary protector in telecommunications and industrial signal line applications, eliminating the need for additional third-party safety validation when deployed per manufacturer-recommended layout guidelines.
What is the maximum clamping voltage of SMBJ60CD-M3/H at its rated surge current?
The maximum clamping voltage (VC) of SMBJ60CD-M3/H is 95.5 V at its peak pulse current (IPPM) of 6.28 A, measured using the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during worst-case surge events - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings.
How does the M3/H suffix affect the construction of SMBJ60CD-M3/H?
The M3/H suffix indicates SMBJ60CD-M3/H is halogen-free, RoHS-compliant, and qualified to JESD201 Class 2 for tin whisker resistance. The "H" denotes packaging in 7″ diameter plastic tape and reel (750 units per reel), while "M3" specifies matte tin plating, UL 94 V-0 molding compound, and industrial-grade qualification - distinguishing it from commercial-grade or non-whisker-resistant variants.
Can SMBJ60CD-M3/H be used in place of a unidirectional SMBJ60D?
No - SMBJ60CD-M3/H is electrically and functionally distinct from SMBJ60D. While both share the same VWM (60 V) and PPPM (600 W), SMBJ60CD-M3/H is bidirectional with no polarity marking and symmetrical clamping, whereas SMBJ60D is unidirectional with a cathode band and only clamps in reverse bias. Substituting one for the other without circuit review risks failure to suppress positive transients (if using SMBJ60D on AC lines) or unintended forward conduction (if using SMBJ60CD-M3/H in DC-only paths).
