DATA SHEET
PHOTOCOUPLER
PS2521-1,-2,-4,PS2521L-1,-2,-4
LARGE FORWARD INPUT TYPE
HIGH ISOLATION VOLTAGE
MULTI PHOTOCOUPLER SIRIES
−NEPOCTM Series−
DESCRIPTION
The PS2521-1, -2, -4 and PS2521L-1, -2, -4 are optically coupled isolators containing a GaAs light emitting diode
and an NPN silicon phototransistor.
The PS2521-1, -2, -4 are in a plastic DIP (Dual In-line Package) and the PS2521L-1, -2, -4 are lead bending type
(Gull-wing) for surface mount.
FEATURES
• Large forward input current (IF = 150 mA)
• High Isolation voltage (BV = 5 000 Vr.m.s.)
• High collector to emitter voltage (VCEO = 80 V)
• High-speed switching (tr = 3 µs TYP., tf = 5 µs TYP.)
• Ordering number of taping product: PS2521L-1-E3, E4, F3, F4, PS2521L-2-E3, E4
• UL approved: File No. E72422 (S)
APPLICATIONS
• Exchange equipment
• FAX/MODEM
• LCR adapter
