Product details
Overview
SMC5K60A-M3/I from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection on power and signal lines. It delivers 5000 W peak pulse power (10/1000 μs), clamps at 96.8 V under 51.7 A surge current, and features 60 V stand-off voltage with 66.7–73.7 V breakdown range at 1 mA test current.
For engineers reviewing the SMC5K60A-M3/I datasheet, SMC5K60A-M3/I pinout, SMC5K60A-M3/I application, or SMC5K60A-M3/I equivalent, this device is selected for automotive-grade ESD and lightning surge protection where low clamping voltage, fast response (<1 ns), and AEC-Q101 qualification are critical - especially in DC power rails, sensor interfaces, and industrial I/O modules.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, activating when reverse voltage exceeds its breakdown threshold to divert transient energy to ground. Its unidirectional polarity enables use on positive-rail applications only, with cathode marked by a band and anode tied to ground reference.
Thermal performance is defined by RthJA = 90 °C/W and RthJM = 4.0 °C/W, supporting reliable operation up to +150 °C junction temperature. It meets IEC 61000-4-2 ESD immunity (30 kV contact/air) and UL 497B safety recognition (E136766).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 60 V - maximum continuous reverse operating voltage before clamping begins |
| Breakdown Voltage (VBR) | 66.7–73.7 V at 1 mA - precise conduction onset ensures predictable overvoltage triggering |
| Clamping Voltage (VC) | 96.8 V at 51.7 A (10/1000 μs) - limits downstream voltage stress during surge events |
| Peak Pulse Power (PPPM) | 5000 W - handles high-energy transients common in automotive load-dump and inductive switching |
| ESD Immunity | 30 kV HBM (contact & air) - exceeds IEC 61000-4-2 Level 4 for robust system-level ESD resilience |
| Operating Temperature | −55 °C to +150 °C - supports under-hood and industrial environments without derating loss |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 3.20 mm × 7.11 mm footprint and 2.06 mm height |
Pinout & Package
SMC5K60A-M3/I uses the standard SMC (DO-214AB) package: molded epoxy case with matte tin-plated leads, MSL level 1 compliant, and halogen-free/RoHS-compliant construction. Polarity is marked by a cathode band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VWM exceeded |
| Anode | Reference node | Typically connected to circuit ground or low-impedance return path for effective clamping |
Key Features

|---|---|
| 5000 W peak pulse power (10/1000 μs) | Enables protection against severe automotive load-dump and industrial switching surges without failure |
| AEC-Q101 qualified | Validated for automotive electronics per stress-test requirements - applicable to full temperature and life-cycle validation |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for downstream ICs |
| UL 497B recognized (E136766) | Meets safety standards for telecom and industrial equipment requiring certified surge protection components |
| MSL Level 1, 260 °C reflow compatible | Supports standard lead-free PCB assembly without moisture-related reliability risk |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs and body control modules from load-dump transients and alternator spikes. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed between power rail and ground, activated within nanoseconds of overvoltage event. Use Value: Clamps to 96.8 V at 51.7 A, preventing damage to microcontrollers and CAN transceivers rated for ≤100 V absolute maximum. |
Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) in factory automation systems exposed to relay-induced EFT. IC Role / Device Role / Timing Role: Unidirectional TVS placed across differential or single-ended signal lines to clamp induced surges before reaching ADC inputs. Use Value: 30 kV HBM ESD rating and sub-1 ns response ensure immunity to repetitive electrostatic discharges in dusty, high-static environments. |
| Telecom DC Power Input Protection | Consumer Device USB/DC Jack Protection |
|
Use Scenario: Securing −48 V telecom rectifier outputs against lightning-induced surges entering central office equipment. IC Role / Device Role / Timing Role: Primary-line TVS mounted at board edge, absorbing multi-kW transients before they propagate into DC-DC converters. Use Value: 5000 W peak power rating and 96.8 V clamping enable compliance with ITU-T K.20/21 surge immunity requirements. |
Use Scenario: Hardening 5 V/9 V/12 V DC input jacks in smart home hubs and portable audio devices against user-handling ESD and adapter plug-in spikes. IC Role / Device Role / Timing Role: Standoff-rated TVS placed directly at connector, limiting voltage seen by internal LDOs and PMICs. Use Value: 60 V VWM allows safe operation across common adapter tolerances while maintaining low leakage (<1 μA) at nominal voltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A-M3/5A | Lower PPPM (600 W), SMB package (smaller footprint), same VWM/VBR range | Suitable for space-constrained consumer designs with lower surge exposure | Select when board area is limited and peak surge energy does not exceed 600 W |
| SMC5K60CA-M3/I | Bi-directional version; identical VWM, VBR, and clamping but symmetric conduction | Required for AC-coupled or bidirectional signal lines (e.g., RS-485, CAN FD) where negative transients occur | Choose only if protection must handle both polarities - SMC5K60A-M3/I is unidirectional and unsuitable for AC signals |
Compared with SMBJ60A-M3/5A and SMC5K60CA-M3/I, the SMC5K60A-M3/I offers 8.3× higher surge power handling than the SMBJ variant and provides optimized unidirectional clamping for DC power rails - making it the preferred choice for automotive and industrial applications demanding robust, single-polarity protection without footprint compromise.

FAQ
What is the breakdown voltage range of the SMC5K60A-M3/I?
The SMC5K60A-M3/I has a specified breakdown voltage (VBR) range of 66.7 V to 73.7 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures consistent turn-on behavior across production lots and supports reliable overvoltage detection in 60 V system rails.
Is the SMC5K60A-M3/I AEC-Q101 qualified?
No - the SMC5K60A-M3/I is not AEC-Q101 qualified. Per Vishay documentation, AEC-Q101 qualification applies only to SMC5K10A through SMC5K20A with HM3 suffix (e.g., SMC5K20AHM3_A/I). The SMC5K60A-M3/I is rated for industrial-grade applications and carries no automotive qualification.
What is the maximum clamping voltage of the SMC5K60A-M3/I at rated surge current?
The SMC5K60A-M3/I clamps to a maximum of 96.8 V at 51.7 A peak pulse current using the 10/1000 μs waveform. This value is confirmed in the Electrical Characteristics table of Vishay document 87742 and defines the upper voltage limit imposed on protected circuits during standardized surge events.
Can the SMC5K60A-M3/I be used in bidirectional signal protection?
No - the SMC5K60A-M3/I is a unidirectional TVS diode and conducts only in reverse bias. For bidirectional protection (e.g., RS-485, CAN, or AC lines), the bi-directional variant SMC5K60CA-M3/I must be used instead. Using SMC5K60A-M3/I on AC signals risks forward conduction and failure.
What packaging option does SMC5K60A-M3/I use, and what is the reel quantity?
The SMC5K60A-M3/I is supplied in 13-inch plastic tape and reel format with a base quantity of 3500 units per reel. The "I" suffix denotes this delivery mode, while "M3" indicates halogen-free, RoHS-compliant construction meeting JESD 201 Class 2 whisker resistance.
