Product details
Overview
SMCJ58A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 58 V standoff voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, 93.6 V maximum clamping voltage (VC) at 16 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform.
For engineers reviewing the SMCJ58A-M3/57T datasheet, SMCJ58A-M3/57T pinout, SMCJ58A-M3/57T application, or SMCJ58A-M3/57T equivalent, key selection criteria include clamping performance under 16 A surge, thermal resistance (RθJA = 75 °C/W), halogen-free RoHS compliance (M3 suffix), and suitability for automotive-grade designs when paired with AEC-Q101 qualified variants.
Technical Context
This TVS diode operates as a voltage-clamping device that remains high-impedance below VWM (58 V) and rapidly transitions to low-impedance conduction above VBR to divert transient energy. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the SMC package supports automated placement and meets UL 94 V-0 flammability requirements.
The device is rated for -55 °C to +150 °C operating junction temperature, exhibits 0.104 %/°C temperature coefficient of VBR, and delivers 1500 W peak pulse power dissipation on standard 8.0 mm × 8.0 mm copper pads - enabling reliable protection against inductive switching transients and ESD events in harsh environments.
Key Specifications

Applications
| Automotive Power Rail Protection | Industrial PLC Input Protection |
|---|---|
Use Scenario: Protecting 24 V CAN bus power rail from load dump and alternator transients in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery feed and regulator input to clamp spikes up to 120 V. Use Value: Limits voltage seen by downstream LDOs and microcontrollers to ≤93.6 V during 16 A surge, preventing latch-up or permanent damage. | Use Scenario: Safeguarding digital input channels of programmable logic controllers exposed to field wiring surges. IC Role / Device Role / Timing Role: Standoff-rated TVS on 24 V sensor input lines to absorb inductive kickback from solenoid drivers. Use Value: Maintains signal integrity by clamping transients within 1 ns while leaking only 1.0 µA at 58 V, minimizing false triggering. |
| Telecom DC Power Supply Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Secondary-side overvoltage suppression in PoE-powered network switches with 48 V DC distribution. IC Role / Device Role / Timing Role: TVS connected across output of DC/DC converter to protect Ethernet PHY and management ICs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58A-M3 | Lower PPPM (400 W), same VWM/VBR/VC, SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; unsuitable for IEC 61000-4-5 Level 4 | Select when space-constrained and surge threat level is ≤400 W |
| SMCJ58CA-M3 | Bidirectional variant; identical VWM/VBR/VC ratings but symmetrical clamping in both polarities | Required for AC-coupled or floating signal lines where polarity reversal occurs | Choose for differential data lines (e.g., RS-485) or AC power inputs |
Compared with SMCJ58A-M3/57T, SMAJ58A-M3 offers reduced surge capability in a smaller package, while SMCJ58CA-M3 provides bidirectional clamping essential for AC or polarity-agnostic circuits - neither is pin-compatible, and layout changes are required for substitution.

FAQ
What is the maximum clamping voltage of the SMCJ58A-M3/57T under a 10/1000 µs surge?
The SMCJ58A-M3/57T has a maximum clamping voltage (VC) of 93.6 V at 16 A peak pulse current under the standardized 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Does the SMCJ58A-M3/57T meet automotive qualification standards?
The SMCJ58A-M3/57T itself is not AEC-Q101 qualified; it carries the M3 suffix indicating halogen-free RoHS compliance for commercial-grade use. However, Vishay offers AEC-Q101 qualified versions under ordering codes like SMCJ58A-HM3_X. For automotive applications requiring qualification, SMCJ58A-M3/57T must be validated per system-level requirements or replaced with the HM3 variant.
What is the thermal resistance junction-to-ambient for SMCJ58A-M3/57T?
The SMCJ58A-M3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes still air conditions and directly impacts safe power derating above 25 °C ambient - for example, at 70 °C ambient, maximum continuous power drops to ~3.2 W.
How does the M3 suffix affect the SMCJ58A-M3/57T's material composition?
The M3 suffix on SMCJ58A-M3/57T indicates halogen-free, RoHS-compliant construction per Vishay's material categorization standard. This means brominated flame retardants and chlorine-based compounds are excluded from the molding compound and plating, supporting environmental compliance for export to EU, China, and other regulated markets without sacrificing electrical or thermal performance.
Can SMCJ58A-M3/57T be used in bidirectional signal protection applications?
No - SMCJ58A-M3/57T is a unidirectional TVS diode, intended for DC rail protection where polarity is fixed. For bidirectional protection (e.g., AC lines or differential buses), the SMCJ58CA-M3 variant must be used. Using SMCJ58A-M3/57T in reverse-biased configurations risks catastrophic failure due to lack of reverse breakdown specification.
