Übersicht

Description

SM4T18CAY is a surface-mount transient voltage suppressor (TVS) diode in the SM4T family. It provides fast, high-energy protection for 18 V-rated power or signal lines, clamping harmful surges to protect downstream circuitry. The device is designed for compact electronics and is suitable for applications requiring fast response to ESD, EFT, and other transient events. It typically offers low leakage in normal operation and a high peak pulse current rating during a surge. Use it by placing it between the protected line and ground (or between lines, depending on the variant) to shunt transients. For exact electrical parameters (standoff/breakdown voltages, capacitance, peak pulse power) and packaging, consult the manufacturer’s datasheet for SM4T18CAY.

Features

SM4T18CAY is a TVS diode array for ESD/surge protection. Typical features (may vary by exact vendor):
- 4-channel transient voltage suppressor (4 lines)
- Working standoff voltage around 18 V (VWM ≈ 18 V)
- Low capacitance per channel for high-speed signal protection
- Bidirectional or unidirectional variants available
- Very low leakage current
- High peak pulse current rating for surge events
- Fast response to ESD events per IEC61000-4-2
- Small surface-mount package; RoHS/compliant; lead-free
- Wide operating temp range (industrial; automotive options often available)
- Suitable for protecting 18 V rails and data/interface lines (e.g., automotive/industrial electronics)
Note: exact electrical specs (capacitance, leakage, peak current, packaging) depend on the manufacturer and variant. Please share the manufacturer/datasheet for precise details.
