PS7241S-1A

PRELIMINARY DATA SHEET OCMOS FETTM PS7241S-1A CURRENT LIMIT TYPE 4-PIN SOP 400 V OCMOS FET (1-ch OCMOS FET) DESCRIPTION The PS7241S-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. Current control circuit of 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. FEATURES Shut down type circuit Limit current (ILMT = 155 to 210 mA) Small and thin package (4-pin SOP, Height = 2.1 mm) 1 channel type (1 a output) Low LED operating current (IF = 2 mA) Designed for AC/DC switching line changer Low offset voltage Ordering number of taping product: PS7241S-1A-E3, E4, F3, F4 UL approved: File No. E72422 (S) APPLICATIONS Note PC, PDA Modem card Telephone, FAX Measurement equipment The information in this document is subject to change without notice.
