Product details
Overview
SMC5K13AHM3_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 features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 21.5 V maximum clamping voltage (VC) at 233 A peak pulse current (IPPM), and 5000 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and used to protect MOSFETs and signal lines in automotive powertrain control units.
For engineers reviewing the SMC5K13AHM3_A/H datasheet, SMC5K13AHM3_A/H pinout, SMC5K13AHM3_A/H application, or SMC5K13AHM3_A/H equivalent, this page delivers verified electrical specs, thermal derating behavior, ESD immunity (30 kV HBM), clamping performance under 8/20 μs surges, and AEC-Q101 qualification status - all critical for automotive-grade surge protection design validation.
Technical Context
This TVS diode operates as a unidirectional clamping device, conducting only during positive transients relative to its cathode-marked end. Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of inductive switching spikes and lightning-induced surges on DC power rails and signal paths.
It is rated for junction temperatures from –55 °C to +150 °C, with thermal resistance RthJA = 90 °C/W and RthJM = 4.0 °C/W. The device meets J-STD-020 MSL Level 1 and passes JESD 201 Class 2 whisker testing, confirming suitability for lead-free reflow assembly in high-reliability automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for protected circuitry. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - Tight breakdown tolerance ensures predictable turn-on threshold across temperature and production lot. |
| VC @ IPPM | 21.5 V at 233 A (10/1000 μs) - Clamping voltage directly limits peak stress on downstream components during surge events. |
| PPPM | 5000 W (10/1000 μs) - Sustains high-energy transients without failure; enables protection of 12 V automotive systems against ISO 7637-2 Pulse 1/2a/5a. |
| TJ max. | +150 °C - Supports operation in under-hood environments and high-power density PCB layouts with limited airflow. |
| ESD Rating | 30 kV (HBM, contact & air) - Meets IEC 61000-4-2 requirements for system-level ESD robustness in infotainment and ADAS interfaces. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, halogen-free, RoHS-compliant, matte tin-plated leads. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink during clamping | Connected to protected line (e.g., 12 V rail); conducts surge current to ground when voltage exceeds VBR. |
| Cathode | Reference terminal / polarity marker | Marked end; tied to system ground or lower-potential node; defines unidirectional conduction direction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control, body electronics, and ADAS sensors per stress test requirements. |
| 5000 W peak pulse power (10/1000 μs) | Enables single-device protection against high-energy load dump and inductive kick events in 12 V systems. |
| 21.5 V clamping at 233 A | Keeps protected ICs (e.g., CAN transceivers, microcontrollers) below absolute maximum ratings during worst-case transients. |
| MSL Level 1, 260 °C peak reflow | Supports standard lead-free SMT assembly without moisture-related popcorning or delamination risks. |
| 30 kV HBM ESD immunity | Reduces need for additional board-level ESD protection on exposed connectors and sensor interfaces. |
Applications

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 | Lower PPPM (400 W), smaller SMA package, same VWM (13 V), higher VC (21.5 V @ 18.2 A). | Not suitable for automotive load dump; limited to low-energy signal-line or secondary-side protection. | Select when space-constrained layout and <500 A surge capability suffice; not AEC-Q101 qualified. |
| SMCJ13A-HM3 | Same SMC package, AEC-Q101 qualified, but rated for 1500 W PPPM (10/1000 μs) and 130 A IPPM. | Insufficient for ISO 7637-2 Pulse 5a compliance; requires parallel devices for full 5000 W handling. | Choose if cost sensitivity outweighs single-device robustness; verify thermal derating for repeated surges. |
Compared with SMAJ13A-M3/86A and SMCJ13A-HM3, the SMC5K13AHM3_A/H uniquely delivers 5000 W surge handling in an AEC-Q101-qualified SMC package - enabling single-component compliance with automotive load dump standards without thermal or layout compromises.

FAQ
What is the clamping voltage of the SMC5K13AHM3_A/H under a 10/1000 μs surge?
The SMC5K13AHM3_A/H has a maximum clamping voltage (VC) of 21.5 V at 233 A peak pulse current under a 10/1000 μs waveform. This value is measured per Figure 3 in the official Vishay datasheet (Doc. #87742) and defines the upper voltage limit imposed on protected circuits during standardized surge events. The SMC5K13AHM3_A/H maintains this clamping performance across its full operating temperature range.
Is the SMC5K13AHM3_A/H AEC-Q101 qualified?
Yes, the SMC5K13AHM3_A/H is AEC-Q101 qualified. Per Vishay documentation, the HM3 suffix denotes AEC-Q101 qualification, and the SMC5K13AHM3_A/H falls within the SMC5K10A–SMC5K20A range explicitly covered by this qualification. This makes the SMC5K13AHM3_A/H suitable for automotive applications including engine control, body electronics, and ADAS subsystems.
What is the standoff voltage (VWM) and breakdown voltage range for the SMC5K13AHM3_A/H?
The SMC5K13AHM3_A/H has a standoff voltage (VWM) of 13 V and a breakdown voltage (VBR) range of 14.4 V to 15.9 V at 1 mA test current. These values are confirmed in Table 1 of the Vishay datasheet (Document Number 87742), ensuring reliable turn-on behavior with minimal leakage (<2.0 μA) below VWM and consistent clamping onset across production lots.
Does the SMC5K13AHM3_A/H meet JEDEC moisture sensitivity level requirements?
Yes, the SMC5K13AHM3_A/H meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This rating allows indefinite floor life at ambient conditions and supports standard lead-free reflow profiles without baking or special handling - a key requirement for high-volume automotive and industrial manufacturing.
What package type does the SMC5K13AHM3_A/H use, and what are its key mechanical features?
The SMC5K13AHM3_A/H uses the SMC (DO-214AB) surface-mount package, with dimensions of 0.260–0.280 inches in length and 0.114–0.126 inches in width. It features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, halogen-free molding compound rated UL 94 V-0, and a cathode identification band. The SMC5K13AHM3_A/H is optimized for automated placement and high thermal dissipation in dense PCB layouts.
