Product details
Overview
SMCJ58CA-E3/51T 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, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCJ58CA-E3/51T datasheet, SMCJ58CA-E3/51T pinout, SMCJ58CA-E3/51T application, or SMCJ58CA-E3/51T equivalent, key selection criteria include bi-directional clamping capability, low incremental surge resistance, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ58CA-E3/51T operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 µA leakage at 58 V), but triggers into low-impedance conduction when transients exceed its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability across -55 °C to +150 °C junction temperature range.
Designed for bi-directional surge suppression, it delivers symmetrical clamping in both polarities without polarity marking-unlike uni-directional variants-and meets UL 497B recognition (QVGQ2) for telecom and industrial protectors. Its thermal resistance (RθJA = 75 °C/W) assumes mounting on minimum recommended 8.0 mm × 8.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - maximum continuous reverse operating voltage before significant leakage |
| VBR min/max | 64.4 V / 71.2 V at 1 mA - guaranteed breakdown window defining turn-on consistency |
| VC @ IPPM | 93.6 V at 16 A - clamping voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 1500 W - peak transient power handling capacity under standardized waveform |
| ID @ VWM | 1.0 µA - ultra-low leakage ensuring minimal standby power loss and signal integrity |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| MSL Level | Level 1 (J-STD-020) - supports standard reflow without baking preconditioning |
Pinout & Package
Package: DO-214AB (SMCJ), surface-mount, bi-directional device with no polarity marking (no cathode band). Case meets UL 94 V-0 flammability rating; matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bi-directional current path | No functional distinction - either terminal serves as input/output for transient energy diversion in either polarity |
| Case (cathode side in uni-directional) | Thermal and mechanical interface | DO-214AB body provides primary heat dissipation path to PCB copper; no electrical isolation from terminals |
Key Features

| AEC-Q101 qualification | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, improving protection margin for sensitive ICs |
| Glass-passivated junction | Ensures stable VBR over time and temperature, critical for long-life industrial deployments |
| MSL Level 1 rating | Eliminates pre-bake requirement in high-volume SMT assembly, reducing manufacturing cost and cycle time |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting LIN bus or CAN FD power rails against load dump and inductive switching spikes in vehicle ECUs. IC Role / Device Role / Timing Role: Shunt TVS that clamps transients above 58 V while remaining invisible to normal 12 V/24 V supply operation. Use Value: Prevents latch-up or permanent damage to transceiver ICs by limiting peak voltage to ≤93.6 V during 1500 W surges. | Use Scenario: Safeguarding analog outputs of pressure or temperature sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed across sensor output and ground to absorb ESD and cable discharge events. Use Value: Maintains signal fidelity with <1 µA leakage at 58 V, while surviving repeated 8 kV contact ESD per IEC 61000-4-2. |
| Telecom Line Interface Protection | Consumer USB Port Surge Suppression |
Use Scenario: Shielding Ethernet PHY power pins (e.g., MDI-X bias supplies) from lightning-induced surges in outdoor base stations. IC Role / Device Role / Timing Role: Primary surge diverter on DC bias lines feeding magnetics, coordinated with secondary GDT or polymer PTC. Use Value: Fast response (<1 ns) and low clamping enable compliance with GR-1089-CORE Level 3 telecom surge immunity requirements. | Use Scenario: Adding robustness to USB 2.0 VBUS lines in smart home hubs exposed to user-handling ESD and hot-plug transients. IC Role / Device Role / Timing Role: Standoff-rated TVS placed between VBUS and ground to clamp overvoltage before reaching USB controller's internal protection. Use Value: 93.6 V clamping ensures USB 5 V regulator remains within safe SOA, even during 1500 W 10/1000 µs surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC58CA | Same VWM (58 V) and PPPM (1500 W), but in smaller SMA package (DO-214AC); lower thermal mass and higher RθJA (100 °C/W) | Less effective for sustained surge duty cycles; suited for space-constrained consumer designs, not under-hood automotive | Select SAC58CA only if board area is critical and thermal derating is acceptable. |
| 1.5KE58CA | Through-hole TO-218 package; identical electrical specs but higher mounting inductance and manual assembly requirement | Not suitable for high-speed automated production; used in legacy industrial power supplies where rework access is prioritized | Choose 1.5KE58CA only for through-hole legacy systems requiring drop-in replacement without PCB redesign. |
Compared with SAC58CA and 1.5KE58CA, the SMCJ58CA-E3/51T offers optimal balance of high-power surge handling, AEC-Q101 qualification, and SMT manufacturability-making it the preferred choice for new automotive and industrial designs requiring reliable, automated assembly.

FAQ
What is the clamping voltage of the SMCJ58CA-E3/51T and how is it measured?
The SMCJ58CA-E3/51T has a maximum clamping voltage (VC) of 93.6 V, measured at a peak pulse current (IPPM) of 16 A under the standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed across the full operating temperature range and reflects the actual voltage seen by protected circuitry during worst-case transient events.
Is the SMCJ58CA-E3/51T suitable for automotive applications?
Yes, the SMCJ58CA-E3/51T is AEC-Q101 qualified and rated for junction temperatures up to +150 °C, making it suitable for under-hood and chassis-mounted automotive applications such as powertrain control modules, body electronics, and ADAS sensor interfaces where robust transient immunity is required.
Does the SMCJ58CA-E3/51T have polarity markings?
No, the SMCJ58CA-E3/51T is a bi-directional TVS diode and carries no polarity marking-there is no cathode band or other visual indicator. Its symmetrical construction allows installation in either orientation on the PCB without affecting electrical performance.
What is the maximum leakage current of the SMCJ58CA-E3/51T at its stand-off voltage?
The SMCJ58CA-E3/51T exhibits a maximum reverse leakage current (ID) of 1.0 µA when biased at its rated stand-off voltage (VWM) of 58 V, measured at 25 °C. This ultra-low leakage preserves signal integrity and minimizes standby power loss in precision analog and battery-powered circuits.
What packaging format is used for the SMCJ58CA-E3/51T?
The SMCJ58CA-E3/51T is supplied in 7-inch plastic tape and reel format (package code 51T), with 850 units per reel. The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 solderability requirements.
