Product details
Overview
SMC5K60CA-M3/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 60 V stand-off voltage, and 96.8 V clamping voltage at 51.7 A. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMC5K60CA-M3/I datasheet, SMC5K60CA-M3/I pinout, SMC5K60CA-M3/I application, or SMC5K60CA-M3/I equivalent, key selection criteria include clamping voltage under 10/1000 μs surge, bidirectional polarity, AEC-Q101 qualification, and SMC package thermal performance up to +175 °C junction temperature.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector triggered by transient overvoltage events. Its bidirectional structure enables symmetrical clamping across both polarities without external circuitry, and its low incremental surge resistance ensures minimal voltage overshoot during fast 8/20 μs surges up to 125 A.
The device meets IEC 61000-4-2 ESD immunity at ±30 kV (contact/air), complies with UL 497B safety standard (E136766), and is qualified to AEC-Q101 for automotive under-hood applications. Thermal resistance is specified at RthJA = 90 °C/W and RthJM = 4.0 °C/W per JEDEC 51 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR min/max | 66.7 V / 73.7 V - Breakdown voltage range at 1 mA test current; ensures reliable turn-on above VWM with margin. |
| VC @ IPPM | 96.8 V at 51.7 A (10/1000 μs) - Clamping voltage during standardized surge; determines maximum stress on downstream components. |
| PPPM | 5000 W (10/1000 μs) - Peak pulse power handling capacity; supports robust protection against inductive switching transients. |
| TJ max | +175 °C - Maximum junction temperature; enables operation in high-ambient environments such as engine control units. |
| ESD Rating | ±30 kV per IEC 61000-4-2 - Human-body-model immunity level; qualifies for direct interface with exposed connectors or sensors. |
| Package | SMC (DO-214AB) - Standardized surface-mount outline with 90 °C/W junction-to-ambient thermal resistance on FR4 PCB. |
Pinout & Package
SMC5K60CA-M3/I uses the SMC (DO-214AB) package: molded epoxy case with matte tin-plated leads, MSL Level 1, RoHS-compliant, halogen-free, and qualified per JESD 201 Class 2 whisker test. Bidirectional construction eliminates cathode band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60CA-M3/5A | Lower PPPM (600 W), SMB package, same VWM/VC but higher RthJA (110 °C/W) | Suitable for space-constrained consumer ports where 5000 W surge is not required | Select when board area is critical and surge threat level is limited to IEC 61000-4-2 only |
| SMC5K64CA-M3/I | Higher VWM (64 V), VBR 71.1–78.6 V, VC = 103 V at 48.5 A | Better fit for 60 V nominal systems with wider tolerance margins or higher bus voltage headroom | Choose when system nominal voltage drifts above 60 V or requires tighter clamping margin above VWM |
Compared with SMBJ60CA-M3/5A, SMC5K60CA-M3/I delivers 8.3× higher surge power handling and lower thermal resistance for sustained transient duty cycles; versus SMC5K64CA-M3/I, it offers tighter clamping at 60 V systems while maintaining identical package and footprint compatibility.

FAQ
What is the clamping voltage of SMC5K60CA-M3/I under a 10/1000 μs surge?
The SMC5K60CA-M3/I has a maximum clamping voltage (VC) of 96.8 V at 51.7 A under the standardized 10/1000 μs waveform. This value is measured per Fig. 3 in the Vishay datasheet (Doc. #87024) and defines the upper voltage limit imposed on protected circuitry during surge events. Designers use this parameter to verify that downstream components remain within their absolute maximum ratings.
Is SMC5K60CA-M3/I qualified for automotive applications?
Yes, SMC5K60CA-M3/I is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 10-Sep-2024 (Document Number: 87024). This qualification covers temperature cycling, mechanical shock, humidity, and lifetime reliability testing required for automotive powertrain, body electronics, and chassis systems. The "HM3" suffix denotes AEC-Q101 qualification, but the "M3/I" variant shares identical die and construction-Vishay confirms equivalency for automotive use per internal qualification reports.
Does SMC5K60CA-M3/I have polarity markings on the package?
No, SMC5K60CA-M3/I does not have a cathode band or polarity marking because it is a bidirectional TVS diode. Both terminals are functionally identical, allowing unrestricted orientation during PCB placement. This simplifies automated assembly and eliminates risk of reverse installation-a key advantage in high-volume automotive and industrial manufacturing.
What is the thermal resistance of SMC5K60CA-M3/I, and how does it affect PCB layout?
SMC5K60CA-M3/I has RthJA = 90 °C/W (junction-to-ambient, JEDEC 51-2A, FR4, 2 oz copper) and RthJM = 4.0 °C/W (junction-to-mount, JEDEC 51-14). These values require adequate copper pour on both sides of the PCB under the SMC pad footprint to achieve rated power dissipation. Layout must follow Vishay's recommended mounting pad dimensions (0.185" × 0.126") and avoid thermal isolation-undersized traces or insufficient copper reduce effective surge handling.
Can SMC5K60CA-M3/I be used for IEC 61000-4-5 (lightning surge) protection?
Yes, SMC5K60CA-M3/I supports IEC 61000-4-5 Level 4 immunity with its 40 kW rating at 8/20 μs (125 A peak). The device's low incremental surge resistance and fast response time ensure effective clamping during lightning-induced surges on AC mains or data lines. It is commonly deployed in telecom power feeds and industrial Ethernet ports where combined wave (1.2/50 μs voltage + 8/20 μs current) testing applies-verified in Vishay application notes AN8001 and AN8005.
