Product details
Overview
SMCG9.0CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 9.0 V stand-off voltage (VWM), 15.4 V maximum clamping voltage (VC) at 97.4 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) with a 10/1000 µs waveform.
For engineers reviewing the SMCG9.0CA-E3/57T datasheet, SMCG9.0CA-E3/57T pinout, SMCG9.0CA-E3/57T application, or SMCG9.0CA-E3/57T equivalent, this device serves as a RoHS-compliant, AEC-Q101-qualified TVS for automotive and industrial signal-line protection where fast response time, low incremental surge resistance, and bidirectional clamping are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 10.0–11.1 V (min/max) at 1.0 mA test current. Its clamping behavior is characterized under standardized 10/1000 µs surge conditions, delivering consistent voltage limiting up to 15.4 V at 97.4 A IPPM - critical for safeguarding downstream ICs and MOSFETs against inductive switching transients.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = +150 °C. The device uses glass-passivated junction technology and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, supporting automated SMT assembly without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.0 V - Maximum continuous reverse stand-off voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 10.0 V / 11.1 V - Breakdown occurs within this range at 1.0 mA; ensures predictable turn-on during transients. |
| VC @ IPPM | 15.4 V at 97.4 A - Clamped voltage seen by protected circuit during full-rated 10/1000 µs surge; limits stress on downstream components. |
| PPPM | 1500 W - Peak surge power handling capability; enables protection against high-energy transients like ISO 7637-2 Pulse 1/2a/5a. |
| ID @ VWM | 1.0 µA - Reverse leakage at rated stand-off voltage; negligible loading on signal lines or sensor outputs. |
| TJ max. | +150 °C - Maximum junction temperature; supports under-hood automotive and industrial environments with minimal derating. |
| Package | SMCG (DO-215AB) - Low-profile surface-mount package with matte tin-plated leads; optimized for automated placement and thermal relief via 8.0 mm × 8.0 mm copper pads. |
Pinout & Package
SMCG9.0CA-E3/57T is housed in the SMCG (DO-215AB) package - a gull-wing, dual-terminal surface-mount outline with no polarity marking for bidirectional operation. Terminals are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
