Product details
Overview
SMC5K10AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It delivers 5000 W peak pulse power (10/1000 μs), clamps at 17.0 V max under 294 A surge current, and features 11.1–12.3 V breakdown voltage at 1 mA test current - ideal for safeguarding MOSFETs and ICs against inductive switching transients in automotive power circuits.
For engineers reviewing the SMC5K10AHM3_A/H datasheet, SMC5K10AHM3_A/H pinout, SMC5K10AHM3_A/H application, or SMC5K10AHM3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 10 V stand-off voltage, 30 kV ESD immunity per IEC 61000-4-2, low incremental surge resistance, and halogen-free RoHS-compliant construction with M3/HM3 whisker-tested terminations.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging avalanche breakdown to limit transient voltages before they damage downstream components. Its 10 V stand-off voltage ensures compatibility with 12 V automotive systems, while its 17.0 V maximum clamping voltage at 294 A (10/1000 μs) provides predictable voltage limiting during high-energy surges.
The SMC5K10AHM3_A/H exhibits fast response time (<1 ns), low thermal resistance (RthJM = 4.0 °C/W), and meets J-STD-020 MSL Level 1 with 260 °C reflow peak. Its junction capacitance is not specified at VWM, but typical values for this family are <100 pF at 1 MHz - suitable for signal-line protection without compromising high-speed integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 μs) | 5000 W - sustains high-energy transients common in automotive load-dump and inductive switch-off events |
| Breakdown Voltage VBR | 11.1–12.3 V at 1 mA - defines precise avalanche onset for reliable triggering above normal operating voltage |
| Stand-off Voltage VWM | 10 V - ensures no conduction during nominal 12 V system operation, minimizing leakage and power loss |
| Max Clamping Voltage VC | 17.0 V at 294 A (10/1000 μs) - limits protected node voltage to safe levels for 3.3 V/5 V logic and gate drivers |
| ESD Immunity | 30 kV contact & air discharge (IEC 61000-4-2) - exceeds automotive EMC requirements for human-body model robustness |
| Operating Temperature | -55 °C to +150 °C - supports under-hood deployment in AEC-Q101 qualified automotive environments |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 0.320" length, optimized for automated assembly and thermal dissipation |
Pinout & Package
SMC5K10AHM3_A/H uses the standard SMC (DO-214AB) package: cathode-indicating band on one end, anode on the opposite. The molded case meets UL 94 V-0 flammability rating; matte tin-plated leads comply with J-STD-002 solderability and JESD 22-B102 wetting balance testing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connects to protected line; conducts surge current to ground when voltage exceeds VBR |
| Anode (non-banded end) | Reference / return path | Typically tied to system ground or low-impedance return plane to complete clamping path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per JEDEC standards |
| Halogen-free & RoHS-compliant | Meets global environmental regulations without compromising flame retardancy (UL 94 V-0) or long-term stability |
| J-STD-020 MSL Level 1 | Allows unlimited floor life and reflow up to 260 °C peak - eliminates baking requirements for production assembly |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients, improving protection margin for sensitive gate oxides |
| 30 kV HBM ESD rating | Provides intrinsic handling robustness during manufacturing and field service without external ESD safeguards |
Applications
| Automotive Power Distribution | Industrial Motor Drive Inputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Lower peak pulse power (400 W), SMA package (smaller footprint, higher RthJA = 110 °C/W) | Suitable only for low-energy signal-line protection; insufficient for automotive load-dump duty | Select SMC5K10AHM3_A/H when >1 kW surge capability and AEC-Q101 qualification are required. |
| SMCJ10A | Same SMC package and 10 V VWM, but rated for 1500 W (10/1000 μs) and not AEC-Q101 qualified | Lacks automotive qualification and lower surge capacity - limited to industrial/commercial use | Choose SMC5K10AHM3_A/H for automotive designs requiring validated reliability and 5000 W headroom. |

FAQ
What is the maximum clamping voltage of the SMC5K10AHM3_A/H under a 10/1000 μs surge?
The SMC5K10AHM3_A/H has a maximum clamping voltage of 17.0 V at 294 A under a 10/1000 μs waveform, as specified in the Vishay datasheet (Document Number: 87742). This value defines the upper voltage limit imposed on protected circuitry during standardized surge events and is critical for ensuring compatibility with downstream 3.3 V or 5 V logic interfaces. The SMC5K10AHM3_A/H maintains this clamping performance across its full operating temperature range.
Is the SMC5K10AHM3_A/H qualified for automotive applications?
Yes, the SMC5K10AHM3_A/H is AEC-Q101 qualified, as confirmed by Vishay's documentation for the SMC5K10A–SMC5K20A series with HM3 suffix. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - validating its suitability for under-hood and powertrain applications. The SMC5K10AHM3_A/H is explicitly designated for automotive use in the ordering information table.
What does the "HM3_A/H" suffix indicate in SMC5K10AHM3_A/H?
The "HM3" portion indicates halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance and AEC-Q101 qualification. "A" denotes the revision level, and "H" specifies the packaging format: 7-inch plastic tape and reel with 850 units per reel. This full suffix confirms the part meets automotive reliability, environmental, and logistics requirements - distinct from non-HM3 variants intended for industrial use only.
Can the SMC5K10AHM3_A/H be used in bidirectional configurations?
No, the SMC5K10AHM3_A/H is strictly unidirectional, as stated in the Vishay datasheet's FEATURES section and electrical characteristics table. It functions only as a cathode-to-anode clamping device and must be oriented with the banded end toward the protected line. For bidirectional protection, two SMC5K10AHM3_A/H devices would need back-to-back connection, but Vishay does not recommend this configuration - instead specifying dedicated bidirectional parts like SMBJ10CA.
What is the thermal resistance from junction to mount (RthJM) for the SMC5K10AHM3_A/H?
The SMC5K10AHM3_A/H has a typical thermal resistance of 4.0 °C/W from junction to mount, measured per JEDEC® 51-14 using the Transient Dual Interface Test Method (TDIM). This low RthJM enables efficient heat transfer to the PCB copper pad or heatsink, supporting sustained surge handling and extended lifetime in thermally constrained automotive layouts. The value is independent of board stack-up and reflects intrinsic package performance.
