Product details
Overview
SMCG10CAHE3/9AT from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for robust overvoltage protection of sensitive electronics. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (PPPM), clamping voltage of 17.0 V at 88.2 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG10CAHE3/9AT datasheet, SMCG10CAHE3/9AT pinout, SMCG10CAHE3/9AT application, or SMCG10CAHE3/9AT equivalent, this device is selected for high-energy surge suppression in automotive sensor interfaces, industrial I/O lines, and telecom signal conditioning where bidirectional clamping, low clamping ratio, and MSL Level 1 solderability are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions-enabling protection of AC-coupled or floating signal paths without polarity constraints. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<5.0 µA at VWM), while the DO-215AB package delivers low thermal resistance (RθJL = 15 °C/W) for effective surge energy dissipation.
The device complies with ANSI/IEEE C62.35 for surge testing and meets UL 497B recognition (QVGQ2, E136766) for protector classification. Its 10/1000 µs waveform rating, 1500 W PPPM, and 88.2 A IPPM are validated on 8.0 mm × 8.0 mm copper pads per terminal-critical for maintaining clamping performance under real-world surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal swing range for protected circuitry. |
| VBR min/max | 11.1 V / 12.3 V at IT = 1 mA - Tight breakdown window ensures predictable turn-on and minimizes risk of premature conduction or delayed clamping. |
| VC @ IPPM | 17.0 V at 88.2 A - Clamping voltage during 10/1000 µs surge; low VC/VWM ratio (~1.7×) enables effective protection of 12 V rail systems. |
| PPPM | 1500 W - Peak pulse power handling capacity; supports high-energy transients like ISO 7637-2 Pulse 5a without degradation. |
| ID @ VWM | ≤5.0 µA - Reverse leakage current at stand-off voltage; low value prevents signal distortion or power loss in high-impedance circuits. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
