Product details
Overview
SMCJ5.0CA/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for robust overvoltage protection of sensitive electronics. It features a 5.0 V stand-off voltage (VWM), 6.40–7.25 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps transients to ≤9.2 V at 163 A, making it suitable for automotive sensor line protection and industrial I/O interface surge suppression.
For engineers reviewing the SMCJ5.0CA/57T datasheet, SMCJ5.0CA/57T pinout, SMCJ5.0CA/57T application, or SMCJ5.0CA/57T equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-214AB mechanical dimensions, clamping performance under 10/1000 µs surges, and direct alternatives with documented VWM/VBR/IPPM trade-offs.
Technical Context
The SMCJ5.0CA/57T operates as a bi-directional avalanche diode, symmetrically clamping voltage transients in both polarities without polarity marking. Its glass-passivated junction enables sub-nanosecond response to ESD and lightning-induced surges, while low incremental surge resistance ensures stable clamping across repeated 10/1000 µs pulses.
Rated for -55 °C to +150 °C junction temperature, it meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak. With 75 °C/W junction-to-ambient thermal resistance and 15 °C/W junction-to-lead, it sustains 6.5 W steady-state dissipation on infinite heatsink at TA = 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse voltage before conduction; defines operating margin below clamping threshold. |
| VBR min/max | 6.40 V / 7.25 V at IT = 10 mA - Confirmed breakdown range ensuring reliable turn-on during transients. |
| VC @ IPPM | 9.2 V at 163 A - Clamped voltage under 10/1000 µs surge; determines maximum stress on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling capability; validates suitability for IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | 1000 µA - Reverse leakage at stand-off voltage; low enough to avoid signal integrity degradation in high-impedance lines. |
| TJ max | +150 °C - Maximum junction temperature; supports under-hood automotive and industrial ambient conditions. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package
SMCJ5.0CA/57T uses the DO-214AB (SMCJ) surface-mount package: 7.11 mm × 6.22 mm × 2.62 mm body, matte tin-plated leads, no polarity marking (bi-directional). Mounting requires 8.0 mm × 8.0 mm copper pads per terminal per datasheet Fig. 2 derating curve.

Use Scenario: Protecting USB-C and barrel jack inputs in wall adapters from user-handling ESD and mains coupling events. IC Role / Device Role / Timing Role: Secondary-level TVS after primary MOV/fuse, providing precise 5.0 V clamping for downstream DC-DC controller ICs. Use Value: Low 1000 µA leakage at 5.0 V prevents standby current drain while enabling full IEC 61000-4-2 ±8 kV contact discharge compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0CA | Lower PPPM (500 W), same VWM (5.0 V), higher VC (11.2 V at 45 A) | Restricted to lower-energy transients (IEC 61000-4-2 only); unsuitable for IEC 61000-4-5 Level 3+ | Select when board space is constrained and surge threat level is limited to ESD-only environments. |
| 1.5KE5.0CA | Through-hole DO-201 package, identical VWM/VBR/VC specs, same 1500 W PPPM | Requires PCB through-hole mounting; not compatible with automated SMT assembly lines | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with SAC5.0CA and 1.5KE5.0CA, the SMCJ5.0CA/57T uniquely combines SMT manufacturability, AEC-Q101 qualification, and full 1500 W surge capacity in a low-profile DO-214AB package-making it the preferred choice for automotive and industrial surface-mount systems requiring production scalability and high-reliability validation.

FAQ
What is the clamping voltage of the SMCJ5.0CA/57T under a 10/1000 µs surge?
The SMCJ5.0CA/57T clamps to a maximum of 9.2 V when subjected to its rated peak pulse current of 163 A under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet Document Number 88394, Table on page 2. The low clamping voltage ensures safe operation of 5 V logic circuits protected by the SMCJ5.0CA/57T.
Is the SMCJ5.0CA/57T suitable for automotive applications?
Yes, the SMCJ5.0CA/57T is AEC-Q101 qualified, explicitly validated for automotive use per the Vishay datasheet revision 11-Dec-12. It supports operating temperatures from -55 °C to +150 °C, passes temperature cycling and HTRB tests, and is rated for under-hood and body electronics. Its bi-directional behavior and 1500 W surge rating make the SMCJ5.0CA/57T appropriate for CAN, LIN, and sensor interface protection in modern vehicles.
Does the SMCJ5.0CA/57T have polarity markings?
No, the SMCJ5.0CA/57T has no polarity marking because it is a bi-directional TVS diode. As stated in the Vishay datasheet, "no marking on bi-directional types." Both terminals are functionally identical, allowing symmetrical placement across differential lines or ungrounded signal paths without orientation constraints-this simplifies layout and eliminates assembly errors associated with cathode band alignment for the SMCJ5.0CA/57T.
What is the maximum leakage current of the SMCJ5.0CA/57T at its stand-off voltage?
The SMCJ5.0CA/57T exhibits a maximum reverse leakage current (ID) of 1000 µA at its 5.0 V stand-off voltage (VWM), as specified in the Electrical Characteristics table on page 2 of the Vishay datasheet. This low leakage ensures minimal impact on high-impedance sensor bias networks and battery-powered circuits, preserving accuracy and standby efficiency in systems using the SMCJ5.0CA/57T.
What package type does the SMCJ5.0CA/57T use, and what are its key mechanical features?
The SMCJ5.0CA/57T uses the DO-214AB (SMCJ) surface-mount package: 7.11 mm × 6.22 mm × 2.62 mm body with matte tin-plated leads solderable per J-STD-002. Its molding compound meets UL 94 V-0 flammability rating, and it complies with MSL Level 1 per J-STD-020. The package supports automated placement and reflow up to 260 °C peak, making the SMCJ5.0CA/57T ideal for high-volume SMT production.
