Product details
Overview
SMC5K58CA-M3/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR), and 5000 W peak pulse power (10/1000 μs). It clamps transients to ≤93.6 V at 53.4 A, enabling robust protection of MOSFETs, ICs, and sensor signal lines in automotive and industrial power electronics.
For engineers reviewing the SMC5K58CA-M3/I datasheet, SMC5K58CA-M3/I pinout, SMC5K58CA-M3/I application, or SMC5K58CA-M3/I equivalent, key selection criteria include its AEC-Q101 qualification, bidirectional polarity, 175 °C max junction temperature, low incremental surge resistance, and compatibility with 13" tape-and-reel automated assembly.
Technical Context
This TVS operates as a voltage-clamping device triggered by overvoltage events-no external bias or control required. Its silicon avalanche structure delivers sub-nanosecond response time and stable clamping across -55 °C to +175 °C operating range, with thermal resistance RthJA = 90 °C/W and RthJM = 4.0 °C/W ensuring effective heat dissipation on standard FR4 PCBs.
The device meets IEC 61000-4-2 ESD immunity up to 30 kV (contact/air), UL 497B safety recognition (E136766), and J-STD-020 MSL Level 1 (260 °C reflow peak), confirming suitability for high-reliability automotive and industrial surface-mount applications requiring repeatable surge suppression performance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58CA-TP | Lower PPPM (400 W), SMA package (smaller footprint, higher RthJA = 110 °C/W), same VWM/VBR range. | Suitable for space-constrained consumer electronics but not automotive under-hood or high-power industrial use. | Select SMC5K58CA-M3/I when 5000 W surge rating, AEC-Q101, or thermal performance in high-ambient conditions is required. |
| 1.5KE58CA | Through-hole DO-201 package, identical electrical specs but no AEC-Q101 qualification or MSL Level 1 rating. | Limited to non-automotive, non-reflow production; unsuitable for automated SMT lines or high-reliability automotive BOMs. | Choose SMC5K58CA-M3/I for surface-mount manufacturability, automotive qualification, and compatibility with modern reflow profiles. |
Compared with SMAJ58CA-TP and 1.5KE58CA, the SMC5K58CA-M3/I delivers 12.5× higher peak pulse power, certified automotive reliability, and optimized thermal performance for high-volume SMT deployment-making it the preferred choice for mission-critical surge protection where power density and qualification matter.

FAQ
What is the clamping voltage of the SMC5K58CA-M3/I at its rated peak pulse current?
The SMC5K58CA-M3/I has a maximum clamping voltage (VC) of 93.6 V at its specified peak pulse current (IPPM) of 53.4 A under the 10/1000 μs waveform condition. This value is measured per Fig.3 in the Vishay datasheet 87024 and defines the upper voltage limit imposed on protected circuitry during a 5000 W transient event. The SMC5K58CA-M3/I maintains this clamping performance across its full operating temperature range.
Is the SMC5K58CA-M3/I suitable for automotive applications?
Yes, the SMC5K58CA-M3/I is AEC-Q101 qualified and rated for operation from -55 °C to +175 °C, making it suitable for under-hood and chassis-mounted automotive systems. Its MSL Level 1 rating, halogen-free construction, and UL 497B recognition further support compliance with automotive electronics requirements. The SMC5K58CA-M3/I is commonly used in battery management, ADAS power supplies, and body control modules.
What does the "M3/I" suffix mean in SMC5K58CA-M3/I?
The "M3" suffix indicates halogen-free, RoHS-compliant, industrial-grade construction with JESD 201 Class 2 whisker resistance. The "I" denotes packaging in 13-inch diameter plastic tape and reel, with a base quantity of 3500 units-optimized for high-speed SMT placement. This differs from "H"-suffixed variants, which use 7-inch reels with 850-unit quantities. The SMC5K58CA-M3/I is fully compatible with standard SMC footprint layouts.
How does the SMC5K58CA-M3/I compare to unidirectional TVS diodes in circuit design?
The SMC5K58CA-M3/I is bidirectional and lacks a cathode band, allowing symmetric clamping on AC or dual-polarity DC lines without orientation constraints. Unlike unidirectional TVS diodes-which conduct only in reverse bias-the SMC5K58CA-M3/I protects both positive and negative transients equally. This simplifies layout for differential signals and eliminates risk of incorrect orientation during assembly. The SMC5K58CA-M3/I is ideal where polarity uncertainty exists or where AC-coupled paths require balanced suppression.
What is the thermal resistance specification for the SMC5K58CA-M3/I?
The SMC5K58CA-M3/I has a junction-to-ambient thermal resistance (RthJA) of 90 °C/W and junction-to-mount (RthJM) of 4.0 °C/W, measured per JEDEC 51-2A (FR4 board, 2 oz. copper) and JEDEC 51-14 (TDIM method), respectively. These values assume proper PCB thermal pad design per the SMC outline drawing. Effective heat dissipation directly impacts sustained surge capability and long-term reliability-especially in high-ambient environments where the SMC5K58CA-M3/I's 175 °C TJ max is leveraged.
