Product details
Overview
SMC5K58A-M3/I 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 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, 5000 W peak pulse power (10/1000 μs), and clamps to 93.6 V at 53.4 A, making it suitable for automotive power line and industrial sensor interface protection.
For engineers reviewing the SMC5K58A-M3/I datasheet, SMC5K58A-M3/I pinout, SMC5K58A-M3/I application, or SMC5K58A-M3/I equivalent, key selection criteria include its AEC-Q101 qualification (industrial grade per note), 30 kV ESD immunity (IEC 61000-4-2), low incremental surge resistance, and M3 halogen-free/RoHS-compliant termination - all critical for high-reliability DC power rail and signal line protection.
Technical Context
This TVS diode operates as a unidirectional clamping device, conducting only during positive transients relative to cathode polarity. Its junction capacitance is <100 pF at VWM (measured at 1 MHz), enabling use on moderate-speed signal lines without signal integrity degradation.
The device delivers 5000 W peak pulse power under 10/1000 μs waveform and sustains 40 kW under 8/20 μs surge, with thermal resistance RthJA = 90 °C/W and RthJM = 4.0 °C/W - confirming suitability for surface-mount PCB layouts with standard 2 oz copper footprints per JEDEC 51-2A/51-14.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for protected circuitry. |
| VBR min/max | 64.4 V / 71.2 V at 1 mA - tight breakdown tolerance ensures predictable turn-on across temperature and unit variation. |
| VC @ IPPM | 93.6 V at 53.4 A (10/1000 μs) - clamping voltage directly limits peak stress on downstream ICs or MOSFETs. |
| PPPM | 5000 W (10/1000 μs) - enables suppression of high-energy transients such as ISO 7637-2 Pulse 1/2a/5a in automotive systems. |
| ESD Rating | ±30 kV HBM (contact & air) - exceeds IEC 61000-4-2 Level 4, supporting robust front-end protection for exposed connectors. |
| TJ max | +150 °C - supports operation in under-hood automotive and industrial environments with elevated ambient temperatures. |
| Package | SMC (DO-214AB) - industry-standard surface-mount outline with 3.20 mm × 7.11 mm footprint and 2.06 mm height, compatible with automated assembly. |
Pinout & Package
SMC5K58A-M3/I uses the standard SMC (DO-214AB) package: a two-terminal surface-mount device with cathode indicated by a color band. The anode and cathode terminals are arranged in axial orientation across the molded body, optimized for PCB-level transient energy shunting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts surge current to ground when voltage exceeds VBR; polarity must match system reference. |
| Anode | Reference/ground return path | Typically tied to system ground plane; completes clamping path; low-inductance layout essential for effective 8/20 μs surge suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping | Protects against positive-going transients only; avoids leakage issues on bidirectional signal lines where reverse conduction is undesirable. |
| 5000 W peak pulse power (10/1000 μs) | Handles high-energy load dump events in 12 V/24 V automotive systems without degradation or failure. |
| AEC-Q101 qualified (industrial grade) | Validated for reliability in harsh environments; though not automotive-grade per ordering code (HM3 required), meets stress test requirements for industrial control units. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets global environmental compliance mandates; matte tin plating ensures solderability per J-STD-002 and whisker resistance per JESD 201 Class 2. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), improving protection margin for CMOS logic and gate drivers. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply rails in vehicle body control modules from ISO 7637-2 load dump pulses and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping element placed between battery input and DC-DC converter input stage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A-M3/5B | Same VWM (58 V), lower PPPM (600 W), SMB package (smaller footprint, higher RthJA = 120 °C/W). | Limited to lower-energy transients; unsuitable for automotive load dump or telecom lightning surges. | Select when space-constrained PCBs require smaller size and surge energy is ≤600 W. |
| SMC5K58A-HM3/I | Identical electrical specs, but HM3 suffix denotes AEC-Q101 qualification for automotive use (vs. M3 industrial grade). | Required for OEM automotive designs needing formal qualification documentation and traceable lot data. | Choose SMC5K58A-HM3/I if automotive production compliance (not just ruggedness) is mandatory. |
Compared with SMC5K58A-M3/I, SMBJ58A-M3/5B trades surge capacity for compactness, while SMC5K58A-HM3/I adds formal AEC-Q101 certification without electrical change - enabling direct substitution only where qualification status, not performance, drives selection.

FAQ
What is the breakdown voltage range of the SMC5K58A-M3/I?
The SMC5K58A-M3/I has a specified breakdown voltage (VBR) range of 64.4 V to 71.2 V at a test current of 1.0 mA, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures consistent clamping behavior across production lots and temperature extremes, supporting reliable overvoltage protection in 58 V nominal systems.
Is the SMC5K58A-M3/I AEC-Q101 qualified?
No, the SMC5K58A-M3/I is not AEC-Q101 qualified. Per Vishay documentation, only parts with the HM3 suffix (e.g., SMC5K58A-HM3/I) carry AEC-Q101 qualification. The M3 suffix indicates halogen-free, RoHS-compliant construction and JESD 201 Class 2 whisker resistance, but not automotive stress testing certification.
What does the "M3" suffix mean in SMC5K58A-M3/I?
The "M3" suffix in SMC5K58A-M3/I denotes halogen-free, RoHS-compliant molding compound and matte tin-plated leads that meet JESD 201 Class 2 whisker resistance requirements. It also specifies packaging in 13-inch tape-and-reel format (3500 units per reel), distinguishing it from the "H" reel variant.
Can SMC5K58A-M3/I be used for bidirectional transient protection?
No, the SMC5K58A-M3/I is a unidirectional TVS diode and provides clamping only for positive transients relative to its cathode. For bidirectional protection (e.g., AC lines or differential signals), a dedicated bidirectional TVS or back-to-back unidirectional configuration is required - SMC5K58A-M3/I alone cannot suppress negative-going surges.
What is the maximum clamping voltage of SMC5K58A-M3/I at rated peak pulse current?
The SMC5K58A-M3/I clamps to a maximum of 93.6 V at its rated peak pulse current of 53.4 A under the 10/1000 μs waveform. This value is guaranteed per datasheet Table "ELECTRICAL CHARACTERISTICS" and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
