Product details
Overview
SMC3K60CA-M3/9A from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in the SMC (DO-214AB) package, rated for 3000 W peak pulse power (10/1000 μs), with a standoff voltage of 60 V, breakdown voltage range 66.7–73.7 V, and clamping voltage of 96.8 V at 31.0 A peak surge current. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMC3K60CA-M3/9A datasheet, SMC3K60CA-M3/9A pinout, SMC3K60CA-M3/9A application, or SMC3K60CA-M3/9A equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with wave-soldering constraints on PCB top-side only.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients induced by inductive load switching or ESD events. Its low incremental surge resistance and fast response time ensure minimal overshoot during 10/1000 μs surge pulses up to 3000 W.
Designed for bidirectional polarity only, it features no polarity marking and is qualified to AEC-Q101 for automotive reliability. The device uses halogen-free, RoHS-compliant materials and meets UL 497B safety recognition (E136766) and J-STD-020 MSL Level 1 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 3000 W (10/1000 μs waveform) - sustains high-energy transients without failure in motor drive or power supply protection |
| Standoff Voltage (VWM) | 60 V - maximum continuous reverse operating voltage before conduction begins |
| Breakdown Voltage (VBR) | 66.7–73.7 V at 1.0 mA - defines onset of avalanche clamping under controlled test conditions |
| Clamping Voltage (VC) | 96.8 V at 31.0 A IPPM - limits transient voltage seen by protected downstream circuitry |
| Operating Temperature | -55 °C to +150 °C - supports under-hood automotive and industrial ambient environments |
| Polarity | Bidirectional - protects against both positive and negative polarity surges without external circuitry |
| Package | SMC (DO-214AB) - standardized surface-mount outline with 8.0 mm × 8.0 mm copper pad area for thermal dissipation |
Pinout & Package
SMC3K60CA-M3/9A uses the standard SMC (DO-214AB) package: molded plastic case with matte tin-plated leads, compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. No polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Anode side marked "K" on unidirectional; not marked on bidirectional) | Surge return path | Connected to system ground or low-impedance reference; forms clamping loop with protected line |
| Anode (unmarked end) | Protected line interface | Directly connected across sensitive node (e.g., MOSFET drain or sensor input) to divert surge energy |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress requirements |
| MSL Level 1 rating | Zero floor life limitation - can be stored indefinitely at ≤30 °C/85 % RH without baking prior to reflow |
| UL 497B recognition (E136766) | Meets safety standards for transient protectors used in telecom and industrial signal line applications |
| Halogen-free & RoHS-compliant | Complies with environmental regulations and enables use in green manufacturing processes |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients, improving protection margin for 3.3 V/5 V logic interfaces |
Applications
| Automotive Power Distribution | Industrial Motor Drive Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMC3K60CAHM3/9A | AEC-Q101 qualified version with identical electrical specs; HM3 suffix denotes automotive qualification grade | Required for new automotive designs where AEC-Q101 compliance is mandatory; same footprint and clamping behavior | Select SMC3K60CAHM3/9A when automotive qualification is required; SMC3K60CA-M3/9A is commercial-grade only |
| SMC3K64CA-M3/9A | Higher standoff voltage (64 V) and clamping voltage (103 V); breakdown range 71.1–78.6 V | Suitable for 65 V nominal bus systems (e.g., 48 V telecom with 20 % tolerance); less margin for 60 V circuits | Choose SMC3K64CA-M3/9A only if system max operating voltage exceeds 60 V; otherwise SMC3K60CA-M3/9A provides optimal margin |
Compared with SMC3K60CAHM3/9A, the SMC3K60CA-M3/9A lacks AEC-Q101 validation but offers identical electrical performance and packaging; versus SMC3K64CA-M3/9A, it delivers tighter clamping headroom for 60 V systems while maintaining full 3000 W pulse capability.

FAQ
What is the maximum clamping voltage of SMC3K60CA-M3/9A at its rated peak pulse current?
The SMC3K60CA-M3/9A has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 31.0 A, measured using the standard 10/1000 μs waveform. This value ensures protected components see no more than 96.8 V during worst-case surge events, making SMC3K60CA-M3/9A suitable for safeguarding 100 V-rated MOSFETs and ICs in automotive and industrial applications.
Is SMC3K60CA-M3/9A qualified for automotive applications?
No, SMC3K60CA-M3/9A is not AEC-Q101 qualified. It carries the M3 suffix indicating halogen-free, RoHS-compliant, commercial-grade construction. For automotive use, the HM3-suffix variant SMC3K60CAHM3/9A must be selected, as it undergoes full AEC-Q101 stress testing and is explicitly approved for under-hood and chassis-mounted systems.
What does the "9A" in SMC3K60CA-M3/9A indicate?
The "9A" in SMC3K60CA-M3/9A is the preferred package code denoting 13-inch diameter plastic tape and reel packaging containing 3500 units. This differs from the "57" code (7-inch reel, 850 units) and affects logistics, pick-and-place feeder compatibility, and minimum order quantities for SMC3K60CA-M3/9A in high-volume SMT assembly.
Can SMC3K60CA-M3/9A be mounted on the bottom side of a PCB using wave soldering?
No, SMC3K60CA-M3/9A is not recommended for PCB bottom-side wave mounting. Per Vishay documentation, this device is intended for top-side placement only due to thermal and mechanical constraints during wave soldering. Bottom-side mounting may compromise solder joint integrity and long-term reliability of SMC3K60CA-M3/9A.
What is the junction temperature limit for continuous operation of SMC3K60CA-M3/9A?
The SMC3K60CA-M3/9A has a maximum operating junction temperature (TJ max.) of +150 °C and a storage temperature range of -55 °C to +150 °C. Derating applies above TA = 25 °C per the published derating curve; sustained operation near 150 °C requires careful thermal design of the PCB copper pad area (recommended 8.0 mm × 8.0 mm) to maintain SMC3K60CA-M3/9A reliability.
