| LH1298 HIGH VOLTAGE, SOLID STATE RELAY OPTOCOUPLER FEATURES * Normally Closed, 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 LH1298 is a single pole single throw (SPST), normally closed (NC), 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 3750 VACRMS. The coupler consists of a AlGaAs LED that is optically coupled to a dielectrically isolated monolithic integrated circuit. The IC chip consists of a photodiode array, control circuitry and high voltage DMOS transistors. The typical ON resistance between the output terminals is 30 at 0 mA LED current. The switch offers low off-state leakage current at LED current of 5 mA or greater. There is on board output current limiting circuitry.
