Product details
Overview
SMCG14CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for clamping voltage transients on signal and power lines. It features a 14 V stand-off voltage (VWM), 15.6–17.2 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), <1.0 µA reverse leakage at VWM, and clamps to ≤23.2 V at 64.7 A IPPM. It is AEC-Q101 qualified and used for ESD and surge protection in automotive sensor interfaces.
For engineers reviewing the SMCG14CA-E3/57T datasheet, SMCG14CA-E3/57T pinout, SMCG14CA-E3/57T application, or SMCG14CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, 1500 W surge rating, DO-215AB 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
This device operates as a silicon avalanche diode configured for symmetrical bidirectional clamping-no polarity marking required-and delivers sub-nanosecond response to transients. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping under repetitive 10/1000 µs surges up to 1500 W.
Thermally, it relies on PCB copper pad area (0.31" × 0.31") for heat dissipation, with RθJL = 15 °C/W to lead and maximum junction temperature of +150 °C. It meets J-STD-020 MSL Level 1 and supports reflow up to 260 °C peak, making it suitable for high-reliability automotive and industrial assembly processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ14CA-E3/57T | Lower PPPM (400 W), same VWM/VBR range, SMA (DO-214AC) package with higher RθJA (110 °C/W). | Suitable for lower-energy transients (IEC 61000-4-2 only); not recommended for IEC 61000-4-5 Level 4. | Select when board space allows larger SMA footprint and surge energy is ≤400 W. |
| TPSMD14CA | Same 1500 W rating and DO-215AB package, but not AEC-Q101 qualified; higher ID (5 µA max at VWM). | Acceptable for industrial/commercial use where automotive qualification is not mandated. | Choose for cost-sensitive non-automotive designs requiring identical thermal and surge performance. |
Compared with SMCG14CA-E3/57T, SMAJ14CA-E3/57T offers reduced surge robustness and thermal performance, while TPSMD14CA matches power and package but lacks automotive qualification-making SMCG14CA-E3/57T the sole option meeting AEC-Q101 + 1500 W in DO-215AB.

FAQ
What is the clamping voltage of SMCG14CA-E3/57T at its rated peak pulse current?
The SMCG14CA-E3/57T clamps to a maximum of 23.2 V at its specified peak pulse current (IPPM) of 64.7 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and verified on the minimum recommended 8.0 mm × 8.0 mm copper pad layout. The clamping voltage directly determines the maximum overvoltage stress imposed on protected circuitry during surge events.
Is SMCG14CA-E3/57T suitable for automotive applications?
Yes, SMCG14CA-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its +150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and validation across HTOL, temperature cycling, and ESD tests confirm suitability for engine control, ADAS sensors, and body electronics where reliability is critical.
Does SMCG14CA-E3/57T have polarity markings?
No, SMCG14CA-E3/57T is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction allows either terminal to serve as anode or cathode, simplifying PCB layout and eliminating orientation-dependent placement errors during automated assembly.
What is the reverse leakage current specification for SMCG14CA-E3/57T at its stand-off voltage?
At its 14 V stand-off voltage (VWM), SMCG14CA-E3/57T exhibits a maximum reverse leakage current (ID) of 1.0 µA at TA = 25 °C. This ultra-low leakage preserves signal fidelity in high-impedance sensor interfaces and minimizes quiescent power loss in battery-powered automotive modules.
What package type does SMCG14CA-E3/57T use, and what are its key mechanical attributes?
SMCG14CA-E3/57T uses the SMCG (DO-215AB) package-a low-profile gull-wing surface-mount case with matte tin-plated leads. Key attributes include UL 94 V-0 flammability rating, compliance with J-STD-002 solderability, JESD 201 Class 2 whisker resistance, and optimized thermal path via 0.31" × 0.31" copper pads per terminal.
