LONG CREEPAGE HIGH ISOLATION VOLTAGE
4-PIN PHOTOCOUPLER
−NEPOC
Series−
DESCRIPTION
The PS2581AL1, PS2581AL2 are optically coupled isolators containing a GaAs light emitting diode and an NPN
silicon phototransistor in a plastic DIP (Dual In-line Package) to realize an excellent cost performance.
Creepage distance and clearance of leads are over 8 millimeters.
The PS2581AL2 is lead bending type (Gull-wing) for surface mounting.
FEATURES
• Lead-free product : Solder plating specification Sn-Bi
• Long creepage and clearance distance (8 mm)
• High isolation voltage (BV = 5 000 Vr.m.s.)
• High-speed switching (t
