SRDA05-4R2G

SRDA05-4R2G Description

The SRDA05-4R2G from onsemi is a high-performance, surface-mount steering-type TVS diode designed for robust transient voltage suppression in general-purpose applications. With a 5V reverse standoff voltage and a minimum breakdown voltage of 6V, it offers reliable protection against voltage spikes. The device clamps transient voltages up to 12V at peak pulse current (Ipp), ensuring minimal stress on downstream components. Its low capacitance of 10pF @ 1MHz makes it suitable for high-speed data lines, while the 500W peak pulse power dissipation (8/20µs) ensures resilience against high-energy transients. Packaged in an 8-SOIC and compliant with ROHS3 and REACH, it is ideal for modern electronics requiring compact, high-reliability protection.

SRDA05-4R2G Features

• Steering (Rail-to-Rail) Topology: Protects bidirectional lines with 4 unidirectional channels, offering superior flexibility.
• High Power Handling: 500W peak pulse power (8/20µs) and 10A peak pulse current (10/1000µs) for robust surge protection.
• Low Clamping Voltage: 12V max clamping voltage minimizes stress on sensitive ICs.
• Low Capacitance: 10pF @ 1MHz ensures minimal signal distortion in high-speed applications.
• Wide Compatibility: 5VWM (working voltage) suits 5V systems, while MSL1 (unlimited) ensures easy storage and handling.
• Compact & Reliable: 8-SOIC package with RoHS3/REACH compliance, ideal for space-constrained designs.
