SMP-40 Photo-MOSFET Relay
The SMP-40 Series is a high-voltage, solid-state Photo-MOSFET relay designed for ultra-reliable switching in compact, high-performance electronic systems. Available in SMD and DIP packages, it supports switching up to 1500 V AC or peak DC and load currents up to 45 mA, making it ideal for applications requiring high isolation and voltage handling in a small footprint.
With a typical on-resistance of 180 Ω, low output capacitance of 83 pF, and minimal off-state leakage current of 1 µA, the SMP-40 Series ensures clean signal transitions and high signal integrity. Its solid-state design eliminates mechanical wear and contact bounce, offering superior resistance to shock, vibration, and environmental contaminants.
This series is optimized for switching both low-level analog signals and higher-level loads such as LEDs, relays, solenoids, and lamps. Its extremely high input-to-output isolation and long operational life make it a dependable solution for industrial, automotive, medical, and test environments.
