Product details
Overview
SMC3K60CAHM3/9A 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), 60 V stand-off voltage (VWM), 66.7–73.7 V breakdown voltage (VBR), and 31.0 A peak pulse current (IPPM). It provides robust clamping protection for automotive-grade sensor signal lines and MOSFET gate drivers.
For engineers reviewing the SMC3K60CAHM3/9A datasheet, SMC3K60CAHM3/9A pinout, SMC3K60CAHM3/9A application, or SMC3K60CAHM3/9A equivalent, key selection criteria include AEC-Q101 qualification, bidirectional polarity, 96.8 V maximum clamping voltage at rated surge current, halogen-free RoHS-compliant construction, and compatibility with reflow soldering per J-STD-020 MSL level 1.
Technical Context
The SMC3K60CAHM3/9A operates as a silicon avalanche diode designed to clamp transient overvoltages before they damage downstream circuitry. Its bidirectional structure enables symmetric suppression of positive and negative transients without polarity sensitivity, making it suitable for AC-coupled or floating signal paths.
It delivers 3000 W peak pulse power under standardized 10/1000 μs waveform conditions, with low incremental surge resistance ensuring stable clamping performance across repeated surges. The device is qualified to AEC-Q101 and rated for junction temperatures up to +150 °C, supporting operation in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before conduction begins; defines safe signal line operating margin. |
| VBR (min/max) | 66.7 V / 73.7 V - Breakdown voltage range at 1 mA test current; ensures reliable turn-on during transients above nominal system voltage. |
| VC @ IPPM | 96.8 V - Clamping voltage at 31.0 A peak pulse current; determines worst-case voltage seen by protected IC or MOSFET. |
| PPPM | 3000 W - Peak pulse power handling capability with 10/1000 μs waveform; supports high-energy ESD and load-dump events. |
| TJ max. | +150 °C - Maximum junction temperature rating; enables use in high-ambient automotive and industrial applications. |
| Polarity | Bidirectional - Symmetric clamping for both polarities; eliminates need for polarity-aware layout or orientation checks. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 8.0 mm × 8.0 mm copper pad area recommendation for thermal reliability. |
Pinout & Package
SMC3K60CAHM3/9A uses the SMC (DO-214AB) package: a two-terminal, surface-mount plastic case with matte tin-plated leads, compliant with J-STD-020 MSL level 1 and JESD 201 class 2 whisker testing. No polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (unmarked end) | Anode/Cathode terminal pair | Both terminals are electrically symmetric; no functional distinction - device conducts identically in either direction during overvoltage events. |
| Anode (unmarked end) | Anode/Cathode terminal pair | Identical to cathode terminal in bidirectional configuration; mounting orientation does not affect electrical behavior. |

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from ESD and load-switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector or IC input pins to limit transient voltage to ≤96.8 V. Use Value: Prevents latch-up or permanent damage to 5 V or 3.3 V interface ICs while maintaining signal integrity during ISO 10605 and ISO 7637-2 compliance testing. |
Use Scenario: Safeguarding digital I/O and feedback lines in PLC modules exposed to relay coil flyback and contact arcing. IC Role / Device Role / Timing Role: Fast-response TVS placed across isolated digital inputs to suppress >1 kV transients before reaching optocoupler or microcontroller GPIO.

| Telecom Line Interface | Consumer Power Adapter Feedback Loop |
Use Scenario: Shielding Ethernet PHY magnetics and PoE controller sense lines from lightning-induced surges in outdoor network equipment. IC Role / Device Role / Timing Role: Primary clamping device on secondary-side data lines, coordinated with upstream GDT or MOV for staged protection. Use Value: UL 497B recognition validates suitability for telecom safety standards; 96.8 V clamping prevents overvoltage stress on 24 V or 48 V bias rails. |
Use Scenario: Protecting optocoupler feedback paths in AC/DC adapters against transformer leakage spikes and mains-borne transients. IC Role / Device Role / Timing Role: Secondary-side TVS across TL431 reference input or phototransistor collector-emitter path. Use Value: Maintains regulation stability by limiting feedback node excursions to <100 V, avoiding false triggering or regulator shutdown. |
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_A | Same electrical specs and AEC-Q101 qualification; differs only in updated suffix notation and minor packaging documentation revision. | No functional difference; intended as direct replacement for legacy SMC3K60CAHM3/9A in new designs. | Select SMC3K60CAHM3_A when sourcing newly released reels or aligning with Vishay's current ordering nomenclature. |
| SMAJ60CA | Lower peak pulse power (400 W vs. 3000 W); same VWM (60 V) and bidirectional polarity; SMA package (smaller thermal mass). | Suitable only for low-energy ESD (IEC 61000-4-2) - not for load dump or ISO 7637-2 testing. | Choose SMAJ60CA only for space-constrained consumer applications with verified low-surge-risk environments. |
Compared with SMC3K60CAHM3/9A, SMC3K60CAHM3_A offers identical performance with updated documentation alignment, while SMAJ60CA trades 87.5 % lower surge capacity for 40 % smaller footprint - making it unsuitable for automotive or industrial surge immunity requirements.

FAQ
What is the clamping voltage of the SMC3K60CAHM3/9A at its rated peak pulse current?
The SMC3K60CAHM3/9A has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 31.0 A under the standard 10/1000 μs waveform. This value is measured and guaranteed per Vishay's datasheet Document Number 89433, and defines the upper voltage limit imposed on protected circuitry during surge events. Designers must ensure downstream components tolerate this clamping level.
Is the SMC3K60CAHM3/9A suitable for new automotive designs?
No - Vishay explicitly marks the SMC3K60CAHM3/9A as "Not for New Designs" in its official documentation, citing migration to the updated SMC3K60CAHM3_A variant. While SMC3K60CAHM3/9A remains available for legacy production and repair, new automotive designs should use SMC3K60CAHM3_A to ensure long-term supply and alignment with current qualification records.
Does the SMC3K60CAHM3/9A have polarity markings on the package?
No, the SMC3K60CAHM3/9A does not feature polarity markings because it is a bidirectional TVS diode. Both terminals are functionally identical, and the device clamps symmetrically for positive and negative transients. Physical orientation during placement has no effect on electrical performance, simplifying PCB layout and automated assembly.
What is the meaning of the 'HM3' suffix in SMC3K60CAHM3/9A?
The 'HM3' suffix in SMC3K60CAHM3/9A indicates halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this grade from commercial 'M3' variants (halogen-free/RoHS but not AEC-Q101 qualified). The HM3 version meets automotive reliability and environmental requirements, including JESD 201 class 2 whisker resistance and MSL level 1 moisture sensitivity.
Can the SMC3K60CAHM3/9A be used in place of the SMAJ60CA?
No - the SMC3K60CAHM3/9A is not a drop-in replacement for the SMAJ60CA due to significant differences in surge capability and package. While both share 60 V VWM and bidirectional polarity, the SMC3K60CAHM3/9A handles 3000 W (10/1000 μs) versus SMAJ60CA's 400 W. Substituting without redesign risks catastrophic failure under high-energy transients.
