Product details
Overview
SMC5K54A-M3/I from Vishay General Semiconductor is a unidirectional 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), 87.1 V maximum clamping voltage at 57.4 A, and 60.0–66.3 V breakdown voltage range. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMC5K54A-M3/I datasheet, SMC5K54A-M3/I pinout, SMC5K54A-M3/I application, or SMC5K54A-M3/I equivalent, this device delivers AEC-Q101-qualified transient suppression for 54 V nominal systems requiring robust ESD immunity (30 kV HBM), low incremental surge resistance, and UL 497B safety recognition.
Technical Context
The SMC5K54A-M3/I operates as a unidirectional avalanche diode that enters conduction when reverse voltage exceeds its 60.0–66.3 V breakdown threshold, clamping transients to ≤87.1 V at 57.4 A (10/1000 μs). Its thermal resistance junction-to-ambient is 90 °C/W, enabling reliable operation up to +150 °C junction temperature.
It meets IEC 61000-4-2 ESD immunity (30 kV contact/air), complies with J-STD-020 MSL Level 1, and features matte tin-plated leads qualified per JESD 22-B102 solderability and JESD 201 Class 2 whisker resistance - all within a halogen-free, RoHS-compliant SMC package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 60.0–66.3 V at 1.0 mA test current - defines precise conduction onset for 54 V system protection |
| Stand-off Voltage VWM | 54 V - maximum continuous reverse operating voltage without leakage exceeding 1.0 μA |
| Clamping Voltage VC | 87.1 V at 57.4 A (10/1000 μs) - limits downstream voltage stress during surge events |
| Peak Pulse Power | 5000 W (10/1000 μs) - sustains high-energy transients common in automotive load-dump and inductive switching |
| Junction Temperature Range | −55 °C to +150 °C - supports under-hood and industrial ambient conditions without derating loss |
| ESD Immunity | 30 kV per IEC 61000-4-2 (HBM contact/air) - exceeds automotive and industrial ESD requirements |
| UL Recognition | UL 497B File E136766 - certified for primary/secondary circuit protection in safety-critical designs |

Applications
| Automotive Power Distribution | Industrial Sensor Signal Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V/48 V power rails in engine control units and battery management systems against load-dump and alternator surges. IC Role / Device Role / Timing Role: Primary transient suppressor placed at power input stage before DC-DC converters and microcontrollers. Use Value: Clamps 5000 W surges to ≤87.1 V, preventing latch-up or permanent damage to downstream 54 V-rated components. |
Use Scenario: Shielding analog and digital signal lines (e.g., CAN, LIN, thermistor inputs) from ESD and switching noise in factory automation sensors. IC Role / Device Role / Timing Role: Point-of-entry TVS on PCB edge connectors and sensor interface traces. Use Value: 30 kV HBM ESD immunity and sub-1 ns response time ensure signal integrity remains intact during electrostatic discharge events. |
| Telecom Power Supply Input | Consumer Power Adapter Output |
Use Scenario: Safeguarding AC-DC front-end rectifiers and PFC controllers in telecom base station power supplies exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Secondary-level surge protector after MOVs, handling residual fast transients before regulation stages. Use Value: 57.4 A peak pulse current capability absorbs energy not captured by upstream protection, reducing stress on downstream FETs. |
Use Scenario: Protecting USB-C PD and 54 V laptop adapter outputs from user-induced cable disconnect spikes and connector arcing. IC Role / Device Role / Timing Role: Output-side TVS placed immediately after secondary-side synchronous rectifier. Use Value: 54 V stand-off voltage aligns with PD 5V–54V profile; 87.1 V clamping ensures connected devices remain within absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ54A-M3/86A | Lower peak pulse power (400 W vs. 5000 W); SMA package (smaller footprint, higher RthJA = 110 °C/W) | Suitable only for low-energy ESD and signal-line protection; not rated for load-dump or industrial surge events | Select when space-constrained PCBs require minimal footprint and surge energy is limited to <500 W |
| SMCJ54A-M3/86A | Same SMC package and 5000 W rating, but higher VBR (60.0–66.7 V) and VC (89.2 V @ 56.1 A); no AEC-Q101 qualification | Acceptable for industrial/commercial use where automotive qualification is not mandated | Choose when AEC-Q101 is unnecessary and minor clamping voltage increase is acceptable for cost optimization |
Compared with SMAJ54A-M3/86A and SMCJ54A-M3/86A, the SMC5K54A-M3/I uniquely combines AEC-Q101 qualification, 5000 W surge capacity, and 87.1 V clamping in an SMC package - making it the only option validated for automotive-grade 54 V system protection with full load-dump compliance.

It meets stress-test requirements for temperature cycling, humidity, mechanical shock, and ESD - making it suitable for engine control, body electronics, and ADAS power domains. The SMC5K54A-M3/I carries the HM3 suffix variant for full AEC-Q101 compliance, though the M3/I version shares identical electrical and thermal specs.
What is the maximum clamping voltage of the SMC5K54A-M3/I under standard surge conditions?
The SMC5K54A-M3/I clamps to a maximum of 87.1 V at 57.4 A peak pulse current using the industry-standard 10/1000 μs waveform. This value is measured per Figure 3 in the datasheet and reflects worst-case device behavior under defined surge conditions. The SMC5K54A-M3/I achieves this clamping performance while maintaining low incremental surge resistance, critical for protecting 54 V-rated ICs and MOSFETs from overvoltage damage.
Does the SMC5K54A-M3/I meet UL safety certification requirements?
Yes, the SMC5K54A-M3/I is UL recognized under file number E136766 for safety standard UL 497B, covering primary and secondary circuit protection in telecommunications and industrial equipment. This certification validates its dielectric strength, flammability (UL 94 V-0), and long-term reliability under surge stress - essential for end-equipment safety approvals. The SMC5K54A-M3/I's halogen-free, RoHS-compliant construction further supports global regulatory compliance.
What packaging format does the SMC5K54A-M3/I ship in?
The SMC5K54A-M3/I ships in 13-inch diameter plastic tape and reel format, with a base quantity of 3500 units per reel, as specified in Vishay's ordering information table. The "I" suffix denotes this reel configuration, while "M3" indicates halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance. This packaging supports automated SMT assembly and meets JEDEC moisture sensitivity level (MSL) 1 requirements for unlimited floor life.
