Product details
Overview
SMCJ58C-E3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection on signal and power lines. It features a 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), 93.6 V clamping voltage at 16 A IPPM, and operates from –55 °C to +150 °C - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMCJ58C-E3/57T datasheet, SMCJ58C-E3/57T pinout, SMCJ58C-E3/57T application, or SMCJ58C-E3/57T equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, UL 497B recognition, low incremental surge resistance, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ58C-E3/57T is a silicon avalanche diode engineered for bi-directional transient suppression, with symmetrical breakdown characteristics in both polarities. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1 µA at VWM), while its low RINC enables effective clamping under high-current surges up to 16 A (10/1000 µs).
Thermally, it delivers 75 °C/W junction-to-ambient thermal resistance (RθJA) on standard PCB pads and supports operation up to 150 °C junction temperature. It meets J-STD-020 MSL Level 1, is RoHS-compliant (E3 suffix), and qualified to AEC-Q101 for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - maximum continuous reverse working voltage before clamping initiates |
| VBR (min/max) | 64.4 V / 71.2 V at 1 mA - guaranteed symmetric breakdown threshold in both directions |
| VC @ IPPM | 93.6 V at 16 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 1500 W - peak transient energy absorption capacity per single event |
| ID @ VWM | <1 µA - ultra-low leakage preserves signal integrity in high-impedance circuits |
| TJ Range | –55 °C to +150 °C - wide operating range suitable for under-hood automotive and industrial environments |

|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor outputs (e.g., pressure, temperature) from load-dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Standby parallel-connected TVS that remains non-conductive until transient exceeds 58 V, then clamps within nanoseconds. Use Value: Prevents damage to precision ADC inputs and transceiver ICs by limiting voltage to ≤93.6 V during 16 A surges. | Use Scenario: Safeguarding PLC digital input modules against induced surges from relay coil switching and motor noise. IC Role / Device Role / Timing Role: Bi-directional shunt protector across 24 V DC input terminals, absorbing repetitive transients without polarity reversal concerns. Use Value: Maintains system uptime by suppressing >1 kV fast transients while drawing <1 µA leakage at nominal 24 V operation. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Shielding Ethernet PHY or RS-485 transceivers from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary front-end clamp on differential pairs, coordinated with common-mode chokes and secondary TVS arrays. Use Value: Achieves UL 497B compliance with 1500 W surge rating and sub-100 ns response time to preserve data integrity. | Use Scenario: Input-stage overvoltage protection in AC-DC adapters subjected to mains transients and capacitor discharge events. IC Role / Device Role / Timing Role: Parallel-connected bi-directional suppressor across bulk capacitor input, triggered only during abnormal line spikes. Use Value: Enables compact design with single-device bi-directional coverage, eliminating need for dual uni-directional diodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC58C | Lower PPPM (600 W), smaller DO-214AC (SMA) package, higher RINC | Not AEC-Q101 qualified; limited to consumer-grade power supplies | Select when space-constrained and surge energy is ≤600 W; verify thermal derating on small pads |
| 1.5KE58CA | Through-hole TO-218 package, same VWM/VBR/VC specs, higher thermal mass but no SMT compatibility | Used in legacy industrial power supplies where board real estate allows through-hole mounting | Choose for high-reliability legacy designs requiring proven field history and manual assembly support |
Compared with SAC58C and 1.5KE58CA, the SMCJ58C-E3/57T offers superior surge robustness (1500 W vs. 600 W), AEC-Q101 qualification for automotive use, and optimized SMT manufacturability - making it the preferred choice for new automotive and industrial designs requiring high-energy bi-directional clamping in compact form factor.

FAQ
What does the "C" suffix in SMCJ58C-E3/57T indicate?
The "C" suffix denotes bi-directional configuration - meaning the SMCJ58C-E3/57T provides symmetrical transient suppression in both forward and reverse polarities. Unlike uni-directional variants (e.g., SMCJ58A), it has no cathode marking and is used where AC signals, floating references, or bidirectional data lines require protection without polarity constraints. This is confirmed in Vishay's datasheet section "Devices for Bi-Direction Applications".
Is SMCJ58C-E3/57T RoHS-compliant and halogen-free?
Yes, the SMCJ58C-E3/57T is RoHS-compliant per Directive 2011/65/EU, as indicated by the "E3" suffix, and meets JEDEC JS709A halogen-free requirements. The device uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and its molding compound satisfies UL 94 V-0 flammability rating - all verified in Vishay's official documentation and ordering information table.
What is the maximum clamping voltage for SMCJ58C-E3/57T under standard test conditions?
The maximum clamping voltage (VC) for SMCJ58C-E3/57T is 93.6 V, measured at 16 A peak pulse current (IPPM) using a 10/1000 µs waveform. This value is specified in the Electrical Characteristics table on page 2 of the Vishay datasheet (Document Number: 88394), and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Does SMCJ58C-E3/57T require heatsinking for standard operation?
No dedicated heatsink is required for SMCJ58C-E3/57T under typical transient conditions, as its thermal design relies on PCB copper pad area (minimum 8.0 mm × 8.0 mm per terminal) for heat dissipation. With a typical RθJA of 75 °C/W and 6.5 W steady-state power dissipation rating, it operates reliably within its –55 °C to +150 °C junction range when mounted per recommended pad layout - confirmed in the Thermal Characteristics section.
How does the AEC-Q101 qualification impact the use of SMCJ58C-E3/57T in automotive designs?
The AEC-Q101 qualification certifies that SMCJ58C-E3/57T has passed rigorous stress tests including temperature cycling, HTRB, and ESD - validating its suitability for automotive applications such as engine control units, ADAS sensors, and body electronics. This qualification is explicitly noted in the datasheet's Mechanical Data section and enables direct use in automotive BOMs without additional component-level qualification effort.
