Product details
Overview
SMCJ100CA/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 100 V stand-off voltage (VWM), 162 V maximum clamping voltage (VC) at 9.3 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) with 10/1000 µs waveform. It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in automotive and industrial systems.
For engineers reviewing the SMCJ100CA/57T datasheet, SMCJ100CA/57T pinout, SMCJ100CA/57T application, or SMCJ100CA/57T equivalent, key selection criteria include bi-directional clamping capability, 1500 W surge rating, DO-214AB thermal performance (RθJA = 75 °C/W), AEC-Q101 qualification, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
The SMCJ100CA/57T operates as a silicon avalanche diode with symmetrical bi-directional breakdown behavior-its electrical characteristics apply identically in both polarities. It uses a glass-passivated junction for stable leakage and fast response (<1 ns), and is rated for -55 °C to +150 °C operating junction temperature with MSL Level 1 moisture sensitivity.
Its clamping action begins at breakdown voltage (VBR min = 111 V, max = 123 V @ IT = 1 mA), limiting transient voltages to ≤162 V under 10/1000 µs surge conditions. Thermal design relies on low RθJL (15 °C/W) to leads and requires PCB copper pad area per datasheet recommendation (0.31" × 0.31") for full 1500 W rating.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Lower PPPM (600 W), same VWM (100 V), SMB package (smaller footprint, higher RθJA) | Suitable for space-constrained consumer designs with lower surge exposure | Select when board area is critical and surge threat level is ≤IEC 61000-4-5 Level 2 |
| SMCJ100AHE3/57T | Identical electrical specs, but AEC-Q101 qualified (HE3 suffix) and RoHS-compliant with whisker-tested leads | Required for automotive production where component qualification and lead finish reliability are mandated | Choose for automotive OEM programs requiring documented AEC-Q101 compliance and JESD 201 Class 2 whisker resistance |
Compared with SMCJ100CA/57T, SMBJ100CA offers reduced surge capacity in a smaller package, while SMCJ100AHE3/57T provides identical protection with enhanced automotive qualification and lead finish assurance-neither is pin-compatible due to differing package outlines (SMB vs. SMCJ), requiring layout revision.

FAQ
What is the clamping voltage of the SMCJ100CA/57T under standard surge conditions?
The SMCJ100CA/57T has a maximum clamping voltage (VC) of 162 V when subjected to a 10/1000 µs waveform at its rated peak pulse current of 9.3 A. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during transient events. The clamping performance is symmetric for both polarities due to its bi-directional construction.
Is the SMCJ100CA/57T suitable for automotive applications?
Yes, the SMCJ100CA/57T is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control, body electronics, and infotainment systems. Its -55 °C to +150 °C operating temperature range, glass-passivated junction, and MSL Level 1 rating support reliable deployment in under-hood and cabin environments. Note that the /57T tape-and-reel packaging is standard for SMT production.
Does the SMCJ100CA/57T have polarity markings on the package?
No, the SMCJ100CA/57T does not feature polarity markings because it is a bi-directional TVS diode. Unlike uni-directional variants (e.g., SMCJ100A), which use a cathode band, the CA suffix indicates symmetrical avalanche behavior in both directions-either terminal functions identically, simplifying PCB layout and orientation during automated placement.
What is the thermal resistance of the SMCJ100CA/57T, and how does it affect PCB layout?
The SMCJ100CA/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W. To achieve its full 1500 W peak pulse rating, the datasheet mandates mounting on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. Reducing pad area increases thermal impedance and derates surge capability proportionally.
How does the SMCJ100CA/57T compare to the SMCJ100A in terms of circuit protection function?
The SMCJ100CA/57T provides bi-directional transient suppression, while the SMCJ100A is uni-directional and requires correct polarity alignment. Both share identical VWM (100 V), VBR (111–123 V), and PPPM (1500 W), but only the CA version protects against voltage reversals-making it ideal for AC-coupled lines, differential buses, or ungrounded systems where polarity cannot be guaranteed during fault conditions.
