Product details
Overview
SMC5K13AHM3_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 a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 5000 W peak pulse power (10/1000 μs), and clamps to ≤21.5 V at 233 A, making it suitable for automotive ECU input protection and industrial sensor interface circuits.
For engineers reviewing the SMC5K13AHM3_A/I datasheet, SMC5K13AHM3_A/I pinout, SMC5K13AHM3_A/I application, or SMC5K13AHM3_A/I equivalent, key selection criteria include clamping voltage under 233 A surge, AEC-Q101 qualification status, unidirectional polarity, SMC package thermal performance, and compatibility with 13" tape-and-reel automated assembly.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, activating when reverse voltage exceeds its breakdown threshold to divert transient energy away from downstream ICs. Its low incremental surge resistance and fast response time (<1 ns) ensure effective suppression of inductive switching spikes and ESD events up to 30 kV (IEC 61000-4-2).
The device is rated for -55 °C to +150 °C junction temperature, with thermal resistance RthJA = 90 °C/W and RthJM = 4.0 °C/W, enabling reliable operation in under-hood automotive environments and industrial control cabinets. Its AEC-Q101 qualification confirms suitability for automotive applications requiring robustness against thermal cycling and mechanical stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before conduction begins; defines safe working range for 12 V nominal systems. |
| VBR min/max | 14.4 V / 15.9 V at 1 mA - Tight breakdown tolerance ensures predictable turn-on across production lots and temperature. |
| VC @ IPPM | ≤21.5 V at 233 A (10/1000 μs) - Clamping voltage directly limits stress on protected MOSFET gate or microcontroller I/O pin. |
| PPPM | 5000 W (10/1000 μs) - Sustains high-energy transients common in automotive load-dump and industrial motor drive scenarios. |
| ESD rating | 30 kV contact/air (IEC 61000-4-2) - Meets stringent electrostatic discharge immunity requirements for exposed connectors and sensors. |
| TJ max | +150 °C - Enables placement near heat-generating components without derating concerns in engine control modules. |
| Package | SMC (DO-214AB) - Industry-standard surface-mount outline with 3.20 mm × 7.11 mm footprint and 1.52 mm height for high-power density layouts. |
Pinout & Package
SMC5K13AHM3_A/I uses the standard SMC (DO-214AB) package: molded epoxy case with matte tin-plated leads, cathode indicated by a color band. The device has two terminals: anode and cathode, mounted in a planar dual-leaded configuration optimized for thermal dissipation on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward bias; connected to system ground or low-side reference in unidirectional TVS configuration. | Provides return path for surge current; must be routed with low-inductance connection to minimize clamping overshoot. |
| Cathode | Protected line connection point; connected to the node requiring overvoltage protection (e.g., 12 V rail or CAN_H). | Color-banded end accepts transient energy and clamps voltage relative to anode; determines polarity-sensitive placement on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements including temperature cycling, humidity bias HAST, and mechanical shock - required for engine control, body electronics, and ADAS modules. |

| Clamping voltage ≤21.5 V at 233 A | Keeps protected 3.3 V or 5 V logic inputs below absolute maximum ratings even during worst-case 10/1000 μs transients. |
| MSL Level 1 (260 °C peak reflow) | Compatible with standard lead-free SMT reflow profiles without moisture sensitivity concerns or baking requirements. |
| UL 497B recognized (E136766) | Meets safety standards for telecom and industrial equipment requiring certified surge protection on primary-side interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-M3/86A | Same VWM (13 V), lower PPPM (400 W), SMA package (smaller thermal mass, higher RthJA = 110 °C/W). | Not AEC-Q101 qualified; limited to consumer/industrial grade where automotive reliability is not required. | Select for cost-sensitive, space-constrained designs with lower surge exposure (e.g., USB port protection). |
| SMCJ13A-HM3_A/I | Same SMC package and AEC-Q101 qualification, but higher PPPM (1500 W), lower clamping voltage (≤21.2 V at 71.5 A). | Insufficient for ISO 7637-2 Pulse 5a compliance due to lower peak current handling (71.5 A vs. 233 A). | Choose when system-level surge testing shows <100 A transients and tighter clamping is prioritized over energy absorption. |
Compared with SMC5K13AHM3_A/I, SMAJ13A-M3/86A offers smaller footprint but lacks automotive qualification and energy handling, while SMCJ13A-HM3_A/I provides better clamping but cannot sustain the same peak current - making SMC5K13AHM3_A/I uniquely suited for high-energy automotive and industrial surge protection.

FAQ
What is the maximum clamping voltage of SMC5K13AHM3_A/I under a 10/1000 μs surge?
The SMC5K13AHM3_A/I clamps to a maximum of 21.5 V when subjected to its rated peak pulse current of 233 A with a 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and is measured per ANSI/IEEE C62.35 standards, ensuring consistent protection margin for downstream 3.3 V or 5 V logic components in the SMC5K13AHM3_A/I application circuit.
Is SMC5K13AHM3_A/I qualified for automotive use?
Yes, SMC5K13AHM3_A/I is AEC-Q101 qualified, as confirmed by Vishay's documentation for the SMC5K10A–SMC5K20A family. This qualification covers temperature cycling, high-temperature operating life, and mechanical shock testing, making SMC5K13AHM3_A/I suitable for engine control units, body control modules, and other automotive electronic systems where reliability under vibration and thermal stress is critical.
What does the "HM3_A/I" suffix indicate in SMC5K13AHM3_A/I?
The "HM3_A/I" suffix denotes three key attributes: "H" indicates 7" tape-and-reel packaging (though "I" overrides this to specify 13" reel), "M3" confirms halogen-free, RoHS-compliant construction meeting JESD201 Class 2 whisker resistance, and "A" is the revision code. The "_A/I" combination specifies 13" diameter plastic tape and reel packaging with 3500 units per reel, optimized for high-volume SMT assembly of SMC5K13AHM3_A/I.
How does SMC5K13AHM3_A/I compare to SMCJ13A in terms of surge capability?
SMC5K13AHM3_A/I delivers 5000 W peak pulse power (10/1000 μs) and handles 233 A, whereas SMCJ13A is rated for 1500 W and 71.5 A. This means SMC5K13AHM3_A/I sustains over 3× more surge energy and can protect against ISO 7637-2 Pulse 5a load-dump events that SMCJ13A cannot withstand - a critical distinction for automotive-grade SMC5K13AHM3_A/I deployment.
What is the thermal resistance of SMC5K13AHM3_A/I, and why does it matter?
SMC5K13AHM3_A/I has a junction-to-ambient thermal resistance (RthJA) of 90 °C/W and junction-to-mount (RthJM) of 4.0 °C/W, per JEDEC 51-2A and 51-14 standards. These values determine how effectively heat from surge dissipation transfers to the PCB and heatsink; lower RthJM enables higher sustained power handling in thermally constrained layouts, directly impacting reliability of SMC5K13AHM3_A/I in high-temperature automotive environments.
