Series Features
SMP-30 Photo-MOSFET Relay
Series DescriptionThe SMP-30 Series is a high-voltage, solid-state Photo-MOSFET relay designed for demanding switching applications in compact electronic systems. Available in SOP, SMD, and DIP packages, it supports switching up to 400 V AC or peak DC and load currents up to 120 mA, making it suitable for medium-power control tasks.
With a typical on-resistance of 21 Ω, low output capacitance of 52 pF, and an off-state leakage current of just 1 µA, the SMP-30 Series ensures clean signal transitions and high reliability. Its solid-state design eliminates mechanical wear and contact bounce, offering enhanced durability and resistance to shock, vibration, and environmental contaminants.
This series is ideal for switching both low-level analog signals and higher-level loads such as LEDs, relays, solenoids, and lamps. Its high input-to-output isolation and long operational life make it a dependable choice for industrial, medical, and test environments.
