Product details
Overview
SMC3K60CAHM3_A from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) in SMC (DO-214AB) package, designed for automotive and industrial electronics protection. It features 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR), 96.8 V clamping voltage at 31.0 A (10/1000 μs), 3000 W peak pulse power, and AEC-Q101 qualification - deployed across power line and signal line surge protection in 12 V battery systems.
For engineers reviewing the SMC3K60CAHM3_A datasheet, SMC3K60CAHM3_A pinout, SMC3K60CAHM3_A application, or SMC3K60CAHM3_A equivalent, key selection criteria include ISO 7637-2 Pulse 1/2a/3a/3b and ISO 16750-2 Pulse b compliance, 30 kV ESD immunity per IEC 61000-4-2, and thermal resistance of 90 °C/W (RthJA) for PCB-level thermal design validation.
Technical Context
This TVS diode operates as a voltage-clamping device during transient overvoltage events, leveraging avalanche breakdown to divert surge current away from sensitive downstream circuitry. Its bidirectional architecture enables symmetric clamping on both polarities without polarity marking, supporting robust protection in AC-coupled or floating signal paths.
It delivers 3000 W peak pulse power under 10/1000 μs waveform and sustains 240 A peak pulse current under 8/20 μs waveform, with low incremental surge resistance ensuring minimal voltage overshoot during fast transients. The device meets MSL Level 1 reflow compatibility (260 °C peak) and JESD 201 Class 2 whisker resistance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60CA | Same VWM (60 V), lower PPPM (400 W), SMA package (smaller footprint, higher RthJA = 150 °C/W) | Limited to low-energy transients (e.g., ESD-only); unsuitable for ISO 7637-2 Pulse 1 or load dump | Select when board space is constrained and surge energy is ≤400 W; verify thermal derating for >100 ms pulses. |
| 1.5KE60CA | Same VWM (60 V), higher PPPM (1500 W), axial DO-201 package (through-hole, manual assembly) | Not AEC-Q101 qualified; lacks MSL Level 1 and JESD 201 whisker compliance | Choose only for non-automotive prototypes or legacy through-hole designs where automated SMT is unavailable. |
Compared with SMAJ60CA and 1.5KE60CA, SMC3K60CAHM3_A uniquely combines 3000 W surge capacity, AEC-Q101 qualification, and SMC package manufacturability - making it the only option qualified for production-grade automotive power line protection requiring ISO 7637-2 compliance and zero rework risk.

FAQ
What is the clamping voltage of SMC3K60CAHM3_A under a 10/1000 μs surge?
The SMC3K60CAHM3_A clamps to 96.8 V at 31.0 A under the standard 10/1000 μs waveform. This value is measured and guaranteed per Vishay Document Number 98241, and represents the maximum voltage seen by downstream components during such an event - critical for ensuring compatibility with 100 V-rated ICs and MOSFETs in automotive power rails.
Is SMC3K60CAHM3_A qualified for automotive use?
Yes, SMC3K60CAHM3_A is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet (Revision 09-Jan-2024, Document Number 98241). It also meets MSL Level 1 reflow requirements and JESD 201 Class 2 whisker resistance - confirming suitability for under-hood and chassis-mounted automotive modules subject to thermal cycling and vibration.
Does SMC3K60CAHM3_A have polarity markings?
No, SMC3K60CAHM3_A is a bidirectional TVS diode and carries no polarity marking on its SMC (DO-214AB) package. Both terminals are functionally identical, enabling flexible PCB layout without orientation constraints - a key advantage for differential signal lines or floating ground architectures.
What standards does SMC3K60CAHM3_A meet for surge immunity?
SMC3K60CAHM3_A meets ISO 7637-2 (Pulse 1, 2a, 3a, 3b), ISO 16750-2 (Pulse b), and IEC 61000-4-2 (±30 kV HBM contact/air) per its official Vishay specification. These certifications validate its use in automotive EMC testing and industrial equipment subjected to conducted and radiated transients.
What is the thermal resistance of SMC3K60CAHM3_A?
The SMC3K60CAHM3_A has a junction-to-ambient thermal resistance (RthJA) of 90 °C/W when mounted on a standard FR4 PCB per JEDEC 51-2A. This value is essential for calculating temperature rise during repetitive surge events and must be used with derating curves in Figure 1 of the Vishay datasheet to ensure TJ remains ≤175 °C.
