| PRELIMINARY DATA SHEET CURRENT LIMIT TYPE 4 PIN SOP 400 V 1-CH OCMOS FET FEATURES * LIMIT CURRENT: ILMT = 155 to 210 mA * SMALL AND THIN PACKAGE: 4 pin SOP, Height = 2.1 mm * 1 CHANNEL TYPE: 1a output * LOW LED OPERATING CURRENT: IF = 2 mA * DESIGNED FOR AC/DC SWITCHING LINE CHANGER * LOW OFFSET VOLTAGE * SURFACE MOUNT AVAILABLE: PS7241C-1A-E3, E4, F3, F4 PS7241C-1A DESCRIPTION The PS7241C-1A is a solid state relay containing GaAs LEDs on the light emitting side (input side) and MOS FETs including current control circuit on the output side. The currrent control circuit of the OCMOS FET protects this device from thermal breakdown and output circuit. It is suitable for analog signal control because of its low offset and high linearity.
