Product details
Overview
SMCJ58-E3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 58 V standoff voltage (VWM), 64.4–71.2 V breakdown range (VBR at 1 mA), 93.6 V clamping voltage (VC) at 16 A peak pulse current, and 1500 W peak pulse power rating with 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial motor drives.
For engineers reviewing the SMCJ58-E3/57T datasheet, SMCJ58-E3/57T pinout, SMCJ58-E3/57T application, or SMCJ58-E3/57T equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), RoHS-compliant packaging, and real-world design context for surge immunity validation in 12 V/24 V systems.
Technical Context
The SMCJ58-E3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering sub-nanosecond response to transients. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked, and its low incremental surge resistance ensures stable clamping under repetitive 1500 W pulses.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it meets J-STD-020 MSL Level 1 (260 °C peak reflow), supports 200 A non-repetitive forward surge (8.3 ms half-sine), and maintains operation across –55 °C to +150 °C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 64.4 V / 71.2 V at 1 mA - guaranteed avalanche onset window defining turn-on consistency |
| VC @ IPPM | 93.6 V at 16 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 1500 W - peak pulse power handling capability under standardized transient waveform |
| IFSM | 200 A - single half-sine surge current rating (8.3 ms), critical for load-dump survival |
| TJ max | +150 °C - maximum junction temperature enabling use in under-hood automotive environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient, guiding heatsinking requirements on PCB |
Pinout & Package

Applications
| Automotive Engine Control Unit (ECU) | Industrial Motor Drive Power Stage |
|---|---|
Use Scenario: Protection against ISO 7637-2 load dump transients (up to 60 V for 400 ms) on 12 V supply rails feeding microcontroller and driver ICs. IC Role / Device Role: Unidirectional TVS placed between battery input and bulk capacitor to clamp surges before they reach LDOs and gate drivers. Use Value: With 93.6 V clamping and 1500 W rating, SMCJ58-E3/57T prevents latch-up or burnout in 3.3 V/5 V logic despite 12 V system-level transients. | Use Scenario: Guarding IGBT gate drive signals against coupling-induced spikes during high-di/dt switching in 400 V DC bus inverters. IC Role / Device Role: TVS mounted directly at gate driver output to suppress >1 kV/µs edge-induced overshoot on isolated gate paths. Use Value: Sub-ns response and 64.4–71.2 V VBR ensure clamping occurs before gate oxide breakdown, preserving MOSFET/IGBT reliability. |
| Telecom Base Station Power Supply | Consumer Appliance Mainboard |
Use Scenario: Safeguarding 48 V DC-DC converter inputs from lightning-induced surges on outdoor telecom cabinet power feeds. IC Role / Device Role: Primary-stage TVS on rectified AC/DC output, coordinated with MOVs and fuses for staged protection. Use Value: 1500 W PPPM and 200 A IFSM allow SMCJ58-E3/57T to absorb Category B/C surges without degradation over 100,000 cycles. | Use Scenario: Protecting USB-C PD port power path from ESD and hot-swap transients in smart home hubs and kitchen appliances. IC Role / Device Role: Secondary-side TVS on VBUS line after buck converter, ensuring ±15 kV contact ESD immunity per IEC 61000-4-2. Use Value: Low leakage (<1 µA) and tight VBR tolerance prevent standby current drain while enabling fast clamping below 100 V. |
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-E3/52T | Lower PPPM (600 W), smaller SMB package (DO-214AA), same VWM/VBR specs | Suitable for space-constrained consumer designs with lower surge exposure (IEC 61000-4-5 Level 3) | Select when board area is critical and peak surge energy does not exceed 600 W |
| SMCJ58AHE3/57T | Identical electrical specs but AEC-Q101 qualified (HE3 suffix); same DO-214AB package and reel packaging | Required for automotive OEM production where component-level qualification is mandated | Choose for automotive programs needing documented AEC-Q101 test reports and traceability |
Compared with SMBJ58A-E3/52T, SMCJ58-E3/57T delivers 2.5× higher surge power handling in the same footprint family; versus SMCJ58AHE3/57T, it lacks formal AEC-Q101 certification documentation though shares identical construction and screening - making it suitable for industrial and telecom applications where qualification is not contractually required.

FAQ
What is the clamping voltage of the SMCJ58-E3/57T under a 10/1000 µs surge?
The SMCJ58-E3/57T has a maximum clamping voltage (VC) of 93.6 V at 16 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during transient events - a key parameter used to verify safe operation margins for downstream ICs powered from the same rail as the SMCJ58-E3/57T.
Is the SMCJ58-E3/57T RoHS compliant and lead-free?
Yes, the SMCJ58-E3/57T carries the "E3" suffix, indicating full compliance with the EU RoHS Directive 2011/65/EU. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE) above threshold limits, and its matte tin-plated leads meet J-STD-002 solderability requirements - confirming suitability for lead-free reflow processes used with the SMCJ58-E3/57T.
Does the SMCJ58-E3/57T have AEC-Q101 qualification?
No, the SMCJ58-E3/57T is not AEC-Q101 qualified; that designation applies only to variants with the "HE3" suffix (e.g., SMCJ58AHE3/57T). The SMCJ58-E3/57T is commercial-grade and RoHS-compliant, meeting MSL Level 1 and JESD 201 Class 1A whisker testing, but lacks the extended stress test reporting required for automotive qualification - important when selecting the correct variant for OEM automotive programs using the SMCJ58-E3/57T.
What is the thermal resistance of the SMCJ58-E3/57T, and how does it affect layout?
The SMCJ58-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on minimum recommended 8.0 mm × 8.0 mm copper pads per terminal. This value guides PCB copper area allocation: reducing RθJA requires larger thermal pads or internal planes, especially in high-temperature environments like engine bays where the SMCJ58-E3/57T may operate near its +150 °C TJ limit.
How does the SMCJ58-E3/57T differ from bi-directional versions like SMCJ58CA?
The SMCJ58-E3/57T is unidirectional, meaning it blocks reverse current until breakdown and conducts only in reverse bias - ideal for DC-powered lines with defined polarity. In contrast, SMCJ58CA is bi-directional, symmetrically clamping both positive and negative transients, suited for AC-coupled or floating signal lines. The "A" suffix in SMCJ58-E3/57T confirms unidirectional configuration, and its cathode band marking must be oriented toward the protected circuit's ground reference - a critical layout detail for correct SMCJ58-E3/57T operation.
