Product details
Overview
SMC3K60CA-M3/57 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 3000 W peak pulse power (10/1000 μs), with a breakdown voltage range of 66.7–73.7 V, clamping voltage of 96.8 V at 31.0 A, and AEC-Q101 qualification for automotive-grade reliability. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges.
For engineers reviewing the SMC3K60CA-M3/57 datasheet, SMC3K60CA-M3/57 pinout, SMC3K60CA-M3/57 application, or SMC3K60CA-M3/57 equivalent, key selection criteria include its 60 V standoff voltage, bidirectional polarity, 150 °C max junction temperature, UL 497B recognition, and halogen-free RoHS-compliant M3 termination.
Technical Context
The SMC3K60CA-M3/57 operates as a clamping-type TVS diode with avalanche breakdown behavior, delivering fast response (<1 ns) to transient overvoltages while maintaining low incremental surge resistance. Its bidirectional structure enables symmetrical protection on AC or differential signal paths without polarity concerns.
Designed for surface-mount assembly per J-STD-020 MSL Level 1, it supports reflow up to 260 °C peak and is not recommended for PCB bottom-side wave soldering. The device meets AEC-Q101 stress testing requirements and carries UL 497B safety certification (E136766).
Key Specifications

| Package | SMC (DO-214AB) - industry-standard 2-pin surface-mount outline with 8.0 mm × 8.0 mm copper pad area recommendation |
| Polarity | Bidirectional - provides symmetrical overvoltage protection on AC-coupled or floating signal lines |
Pinout & Package
SMC3K60CA-M3/57 uses the standard SMC (DO-214AB) package: a 2-terminal surface-mount device with cathode band marking omitted on bidirectional variants. Terminals are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and qualified to JESD 201 Class 2 whisker test.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMC3K60CAHM3/57 | AEC-Q101 qualified version with identical electrical specs; HM3 suffix denotes automotive-grade qualification and same M3 termination | Required for automotive OEM designs needing formal AEC-Q101 documentation and traceability | Select SMC3K60CAHM3/57 when automotive qualification evidence (test reports, PPAP) is contractually mandated |
| SMC3K64CA-M3/57 | Higher 64 V standoff and 71.1–78.6 V breakdown; clamps at 103 V (vs. 96.8 V) at 29.1 A | Better suited for 65–70 V nominal systems where tighter margin above operating voltage is needed | Choose SMC3K64CA-M3/57 if design requires higher VWM headroom while retaining SMC footprint and 3000 W rating |
Compared with SMC3K60CA-M3/57, the HM3 variant adds formal AEC-Q101 validation without electrical change, while SMC3K64CA-M3/57 trades lower clamping voltage for higher standoff-enabling optimized protection in systems with elevated DC bias or tighter VCLAMP margins.

FAQ
What is the maximum clamping voltage of the SMC3K60CA-M3/57 under standard test conditions?
The SMC3K60CA-M3/57 has a maximum clamping voltage (VC) of 96.8 V when subjected to its rated peak pulse current of 31.0 A using the 10/1000 μs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events. Designers must verify that downstream components tolerate this clamped level under worst-case thermal and aging conditions.
Is the SMC3K60CA-M3/57 suitable for automotive applications?
Yes, the SMC3K60CA-M3/57 is rated for operation from −55 °C to +150 °C and meets AEC-Q101 stress test requirements. While the M3 suffix indicates commercial-grade qualification, its electrical and thermal specifications align with automotive subsystem needs such as body control modules and infotainment power rails. For full AEC-Q101-certified documentation, consider the SMC3K60CAHM3/57 variant.
Does the SMC3K60CA-M3/57 have polarity markings on the package?
No, the SMC3K60CA-M3/57 does not feature polarity markings because it is a bidirectional TVS diode. Unlike unidirectional devices, it lacks a cathode band or other visual indicators-its symmetrical construction allows installation in either orientation across protected lines. Layouts must treat both terminals as functionally interchangeable for clamping purposes.
What is the standoff voltage rating of the SMC3K60CA-M3/57, and how does it relate to system operating voltage?
The SMC3K60CA-M3/57 has a standoff voltage (VWM) of 60 V, meaning it remains non-conductive up to this DC or RMS voltage level. For reliable operation, system nominal voltage should be ≤ 80 % of VWM-e.g., ≤48 V for a 60 V-rated device-to accommodate tolerances, ripple, and temperature drift. This ensures no leakage-induced heating or premature clamping during normal operation.
Can the SMC3K60CA-M3/57 replace older SMC3K60CA parts without layout changes?
Yes, the SMC3K60CA-M3/57 uses the standard SMC (DO-214AB) package with identical mechanical dimensions and terminal configuration as legacy SMC3K60CA variants. Its M3 suffix confirms halogen-free, RoHS-compliant construction and JESD 201 Class 2 whisker resistance-making it a direct drop-in replacement for boards designed for prior revisions, provided the application does not require AEC-Q101 certification.
