LH1056

LH1056 HIGH VOLTAGE, SOLID STATE RELAY OPTOCOUPLER FEATURES Normally Open, Single Pole Single Throw Operation Control 350 VAC or DC Voltage Switch 100 mA Loads LED Control Current, 1.5 mA Low ON-Resistance dv/dt, >500 V/ms Isolation Test Voltage, 3750 VACRMS Current Limiting Underwriters Lab File # E52744 APPLICATIONS Telephone Switch Hook High Voltage Test Equipment TRIAC Driver Motor Control Industrial Control Systems DESCRIPTION The LH1056 is a single pole single throw (SPST), normally open (NO), solid state relay. The relay can control AC or DC loads currents up to 100 mA, with a supply voltage up to 350 V. The device is packaged in a six pin 0.3 inch dual-in line package. This package offers an insulation dielectric withstand of 7500 VACPK. The coupler consists of a AlGaAs LED that is optically coupled to a dielectrically isolated photodiode array which drives two series connected high voltage MOS transistors. The typical ON-Resistance is 30 Ω at 25 mA and is linear up to 50 mA. The incremental resistance drops to less than 20 Ω beyond 50 mA while reducing internal power dissipation at high load currents. There is built-in current limiting circuitry in the detector chip.
