Product details
Overview
SMCJ5.0CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 5.0 V stand-off voltage (VWM), 1500 W peak pulse power rating (PPPM), and clamps transients to ≤9.2 V at 163 A (10/1000 µs waveform), making it suitable for automotive sensor signal lines, industrial I/O ports, and DC power rail protection.
For engineers reviewing the SMCJ5.0CA-E3/57T datasheet, SMCJ5.0CA-E3/57T pinout, SMCJ5.0CA-E3/57T application, or SMCJ5.0CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification eligibility (via HE3 suffix variants), low clamping voltage under surge, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on standard 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ5.0CA-E3/57T operates as a silicon avalanche diode with symmetrical breakdown behavior in both polarities, enabling protection against voltage transients regardless of polarity-critical for AC-coupled or floating signal paths. Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and repeatable clamping performance across temperature (-55 °C to +150 °C).
It delivers fast response time (<1.0 ps), low incremental surge resistance, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead), supporting reliable operation under repetitive surge conditions when mounted per recommended pad layout.

IC Role / Device Role / Timing Role: Secondary-level protection after connector-level ESD diodes, providing low-capacitance, low-clamp backup for high-speed signaling. Use Value: Clamps ESD events to <9.2 V within picoseconds while adding <10 pF capacitance-no signal integrity impact on 480 Mbps USB 2.0 links. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0B-TB-E3 | Unidirectional; lower PPPM (600 W); same VWM (5.0 V); DO-214AA (SMA) package | Requires polarity-aware placement; insufficient for ISO 7637-2 Pulse 5a; suited for low-energy consumer signal lines | Select only if space-constrained and surge energy is <600 W; verify unidirectional system grounding |
| SMCJ5.0A-E3/57T | Unidirectional variant; identical VWM, PPPM, and package; cathode band marking required | Applicable only where transients are known to be unidirectional (e.g., regulated DC outputs with ground-referenced loads) | Choose when protecting single-polarity rails and board layout allows fixed orientation; avoids bidirectional leakage trade-off |
Compared with SAC5.0B-TB-E3 and SMCJ5.0A-E3/57T, the SMCJ5.0CA-E3/57T uniquely supports polarity-agnostic placement and higher surge immunity-making it optimal for floating, AC-coupled, or safety-critical bidirectional interfaces where layout flexibility and robustness are prioritized over minimal footprint.

FAQ
What is the clamping voltage of the SMCJ5.0CA-E3/57T under maximum rated surge current?
The SMCJ5.0CA-E3/57T clamps to a maximum of 9.2 V when subjected to its peak pulse current (IPPM) of 163 A under the standardized 10/1000 µs waveform. This value is measured at 25 °C and confirmed per the Vishay datasheet (Document Number: 88394, Rev. 09-Jan-2024). The low clamping voltage ensures downstream 5 V logic devices remain within safe operating limits during surge events. Designers must verify thermal derating above 25 °C using Fig. 2 in the SMCJ5.0CA-E3/57T datasheet.
Is the SMCJ5.0CA-E3/57T RoHS-compliant and lead-free?
Yes, the SMCJ5.0CA-E3/57T is RoHS-compliant and lead-free. The "E3" suffix explicitly denotes Vishay's commercial-grade, RoHS-compliant construction with matte tin-plated leads that meet J-STD-002 and JESD 22-B102 solderability requirements. It also passes JESD 201 Class 2 whisker testing. Full compliance documentation, including material declarations and UL recognition (QVGQ2), is available in the official Vishay datasheet for SMCJ5.0CA-E3/57T.
Does the SMCJ5.0CA-E3/57T have polarity markings on the package?
No, the SMCJ5.0CA-E3/57T does not feature polarity markings because it is a bidirectional device. Unlike unidirectional variants (e.g., SMCJ5.0A-E3/57T) that use a cathode band, the SMCJ5.0CA-E3/57T has symmetrical electrical characteristics in both directions-so either terminal functions identically as anode or cathode depending on applied voltage polarity. This eliminates orientation concerns during automated placement and simplifies PCB design for floating or AC-coupled nodes.
What is the maximum operating junction temperature for the SMCJ5.0CA-E3/57T?
The SMCJ5.0CA-E3/57T has a maximum operating junction temperature (TJ max.) of +150 °C, as specified in the Vishay datasheet. This rating enables reliable operation in under-hood automotive, industrial motor drives, and power supply applications where ambient temperatures exceed 105 °C. Derating of peak pulse power begins above TA = 25 °C per Figure 2, and thermal performance depends on PCB copper pad area-minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) per terminal is recommended for full 1500 W rating.
Can the SMCJ5.0CA-E3/57T be used in AEC-Q101 qualified designs?
The base SMCJ5.0CA-E3/57T is commercial-grade, but Vishay offers AEC-Q101 qualified versions under the HE3 and HM3 suffixes (e.g., SMCJ5.0CAHE3_A/H). These variants undergo additional stress testing per AEC-Q101 and are intended for automotive applications like ADAS sensors and body control modules. For qualification-critical designs, specify the HE3 or HM3 version-not the E3/57T-and confirm compliance via Vishay's official AEC-Q101 certificate for the SMCJ5.0CAHE3 family. The SMCJ5.0CA-E3/57T itself is not AEC-Q101 certified.
