DESCRIPTION
The LH1518 is an SPST normally open switch (1 Form A) that can replace electromechanical relays in many applications. The relay is constructed using a GaAlAs LED for actuation control and high reliable MOSFETs for the output switch. In addition, it employs current-limiting circuitry to provide overvoltage protection. The LH1518 provides current limiting also for unidirectional DC applications.
FEATURES • Isolation test voltage 5300 VRMS • Load voltage 250 V • Load current 155 mA / 300 mA • Clean bounce free switching • Current limit protection • Low power consumption • Material categorization: for definitions of
