Product details
Overview
SMC5K58A-M3/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 5000 W peak pulse power (10/1000 μs), 93.6 V maximum clamping voltage at 53.4 A, and 64.4–71.2 V breakdown voltage range. It protects MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMC5K58A-M3/H datasheet, SMC5K58A-M3/H pinout, SMC5K58A-M3/H application, or SMC5K58A-M3/H equivalent, this device is selected for robust ESD and lightning surge immunity in DC power rails and interface lines where clamping voltage ≤93.6 V and unidirectional transient suppression are required.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents <1.0 μA leakage at 58 V stand-off, then rapidly avalanches when transients exceed its 64.4–71.2 V breakdown threshold. Its low incremental surge resistance ensures stable clamping during 5000 W pulses.
It meets IEC 61000-4-2 ±30 kV contact/air discharge ESD immunity and is halogen-free, RoHS-compliant, and MSL Level 1 rated. Though not AEC-Q101 qualified (only SMC5K10A–SMC5K20A carry HM3 suffix), it is rated for -55 °C to +150 °C junction operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 64.4 V min / 71.2 V max at 1 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| Stand-off Voltage VWM | 58 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA; sets safe operating margin below VBR |
| Clamping Voltage VC | 93.6 V at 53.4 A (10/1000 μs) - actual voltage seen by protected circuit during worst-case surge |
| Peak Pulse Power | 5000 W (10/1000 μs) - energy-handling capacity sufficient for ISO 7637-2 pulse 5a/b and IEC 61000-4-5 line surges |
| Junction Temperature Range | -55 °C to +150 °C - enables deployment in under-hood automotive and industrial environments without derating |
| ESD Immunity | ±30 kV per IEC 61000-4-2 (HBM/contact & air) - provides system-level electrostatic discharge hardening without external shielding |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, matte tin-plated leads, halogen-free, RoHS-compliant. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ58A-M3/52 | Lower PPPM (600 W), SMB package (smaller footprint), same VBR range (64.4–71.2 V) | Suitable for space-constrained consumer electronics; insufficient for automotive load-dump duty | Select SMC5K58A-M3/H when ≥5000 W surge handling and DO-214AB mechanical robustness are required. |
| 1.5KE56A | Through-hole TO-218 package, higher VC (93.6 V → 96.8 V), same 5000 W rating | Used in legacy industrial power supplies; incompatible with SMT assembly and automated inspection | Choose SMC5K58A-M3/H for modern SMT production, reflow compatibility, and reduced board area vs. through-hole alternatives. |

FAQ
What is the maximum clamping voltage of the SMC5K58A-M3/H under a 10/1000 µs surge?
The SMC5K58A-M3/H has a maximum clamping voltage of 93.6 V at 53.4 A under a 10/1000 µs waveform. This value is measured per Figure 3 in the official Vishay datasheet (Document Number: 87742) and represents the peak voltage imposed on the protected circuit during worst-case surge conditions. The SMC5K58A-M3/H maintains this clamping performance across its full operating temperature range.
Is the SMC5K58A-M3/H AEC-Q101 qualified?
No, the SMC5K58A-M3/H is not AEC-Q101 qualified. Per Vishay's ordering information and qualification notes, only SMC5K10A through SMC5K20A variants with the HM3 suffix (e.g., SMC5K20AHM3_A/H) carry AEC-Q101 qualification. The SMC5K58A-M3/H is rated for industrial-grade operation from -55 °C to +150 °C but lacks formal automotive qualification documentation.
What does the "-M3/H" suffix indicate in SMC5K58A-M3/H?
The "-M3" suffix denotes halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance. The "/H" indicates packaging in 7-inch diameter plastic tape and reel, with a base quantity of 850 units per reel. This packaging format supports standard SMT pick-and-place equipment and is specified in Vishay's ordering information table for the SMC5K58A-M3/H.
Can the SMC5K58A-M3/H be used in bidirectional configurations?
No, the SMC5K58A-M3/H is strictly unidirectional. Its internal structure and datasheet specifications-including polarity marking (cathode band), VBR test direction, and absence of reverse standoff rating-confirm single-quadrant operation. For bidirectional protection, a dedicated bidirectional TVS such as SMBJ58CA-M3/52 must be selected instead of the SMC5K58A-M3/H.
What is the thermal resistance junction-to-ambient (RthJA) for the SMC5K58A-M3/H?
The thermal resistance junction-to-ambient (RthJA) for the SMC5K58A-M3/H is 90 °C/W, measured per JEDEC® 51-2A on a standard FR4 PCB with 2 oz. copper and the recommended mounting pad layout. This value enables accurate thermal modeling of power dissipation during repetitive surge events and confirms suitability for operation up to +150 °C junction temperature when ambient and layout constraints are observed.
