Product details
Overview
SMC5K15AHM3_A/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 features 15 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR), 24.4 V clamping voltage at 205 A (10/1000 μs), 5000 W peak pulse power, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMC5K15AHM3_A/I datasheet, SMC5K15AHM3_A/I pinout, SMC5K15AHM3_A/I application, or SMC5K15AHM3_A/I equivalent, key selection criteria include clamping performance under 10/1000 μs transients, unidirectional polarity for DC-biased rails, thermal resistance (RthJA = 90 °C/W), MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction with matte tin leads.
Technical Context
The SMC5K15AHM3_A/I operates as a voltage-clamping device triggered by reverse-biased avalanche breakdown above its VBR threshold. Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD (30 kV HBM) and lightning-induced surges (8/20 μs, up to 1231 A).
Designed for surface-mount implementation on FR4 PCBs with standard footprint, it delivers stable clamping across -55 °C to +150 °C junction temperature range and meets UL 497B safety recognition (E136766) and IEC 61000-4-2 compliance.

Use Scenario: Shielding Ethernet PHY power pins (e.g., PoE midspan injectors) from induced lightning surges. IC Role / Device Role / Timing Role: Primary-level TVS on DC input path, coordinated with secondary GDT or polymer PTC. Use Value: Withstands 8/20 μs surges up to 1231 A while maintaining clamping below IC absolute maximum ratings. | Use Scenario: Hardening 5 V USB VBUS input on portable media players against hot-plug and cable ESD events. IC Role / Device Role / Timing Role: Standoff-rated TVS on input side of USB port, positioned before overvoltage protection ICs. Use Value: Provides 30 kV HBM ESD immunity without degrading 5 V regulation or introducing capacitance-related signal distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-M3/87A | Lower PPPM (400 W), SMA package (smaller footprint, higher RthJA = 110 °C/W) | Suitable only for lower-energy transients; not AEC-Q101 qualified | Select when space-constrained and surge threat level is limited to IEC 61000-4-5 Level 3 (1 kV/2 kA) |
| SMCJ15A-HM3_A/I | Same SMC package and AEC-Q101 qualification, but 1500 W PPPM rating (3× lower energy handling) | Used where cost optimization outweighs need for 5 kW surge margin | Choose if design validation confirms worst-case surge remains below 1500 W - avoids over-spec'ing |
Compared with SMC5K15AHM3_A/I, SMAJ15A-M3/87A offers smaller size but significantly reduced surge capability and no automotive qualification, while SMCJ15A-HM3_A/I retains identical packaging and qualification but trades 67 % peak power capacity for cost efficiency in less demanding environments.

FAQ
What is the clamping voltage of the SMC5K15AHM3_A/I under a 10/1000 µs surge?
The SMC5K15AHM3_A/I clamps to a maximum of 24.4 V when subjected to its rated peak pulse current of 205 A using the 10/1000 µs waveform. This value is measured at the device terminals and represents the upper limit of voltage imposed on the protected circuit during surge events, ensuring downstream components remain within safe operating limits.
Is the SMC5K15AHM3_A/I qualified for automotive applications?
Yes, the SMC5K15AHM3_A/I carries AEC-Q101 qualification, confirming its suitability for automotive use. The "HM3" suffix explicitly denotes AEC-Q101 compliance, and the device is rated for operation from -55 °C to +150 °C junction temperature - meeting requirements for engine bay and body-control module deployments.
Does the SMC5K15AHM3_A/I have UL safety certification?
Yes, the SMC5K15AHM3_A/I is UL recognized under file E136766 to UL 497B for transient voltage surge suppressors. This certification validates its use in both primary- and secondary-circuit protection applications where regulatory safety compliance is mandatory, such as in automotive infotainment power supplies and industrial gateways.
What is the moisture sensitivity level (MSL) of the SMC5K15AHM3_A/I?
The SMC5K15AHM3_A/I is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at conditions ≤30 °C and ≤85 % relative humidity. No baking or dry-pack handling is required prior to reflow soldering, simplifying manufacturing logistics and reducing risk of popcorning during assembly.
How does the SMC5K15AHM3_A/I differ from the SMCJ15A-HM3_A/I?
The SMC5K15AHM3_A/I delivers 5000 W peak pulse power (10/1000 µs), whereas the SMCJ15A-HM3_A/I is rated at 1500 W - a 67 % reduction. Both share the same SMC package, AEC-Q101 qualification, and 15 V stand-off voltage, but the SMC5K15AHM3_A/I is intended for higher-threat environments like automotive load-dump protection where greater energy absorption is critical.
