4N25

4N25 Phototransistor Optocoupler General Purpose Type Data Sheet Lead (Pb) Free RoHS 6 fully compliant RoHS 6 fully compliant options available; -xxxE denotes a lead-free product Description The 4N25 is an optocoupler for general purpose applications. It contains a light emitting diode optically coupled to a photo-transistor. It is packaged in a 6-pin DIP package and available in wide-lead spacing option and lead bend SMD option. Response time, tr, is typically 3 µs and minimum CTR is 20% at input current of 10 mA. Applications • I/O interfaces for computers • System appliances, measuring instruments • Signal transmission between circuits of different potentials and impedances Features • Response time (tr: typ., 3 µs at VCE = 10 V, IC = 2 mA, RL = 100 Ω) • Current Transfer Ratio (CTR: min. 20% at IF = 10 mA, VCE = 10 V) • Input-output isolation voltage (Viso = 2500 Vrms) • Dual-in-line package • UL approved • CSA approved • IEC/EN/DIN EN 60747-5-2 approved • Options available: – Leads with 0.4" (10.16 mm) spacing (W00) – Leads bends for surface mounting (300) – Tape and reel for SMD (500) – IEC/EN/DIN EN 60747-5-2 approvals (060) CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD. 4N25 is UL Recognized with 2500 Vrms for 1 minute per UL1577 and is approved under CSA Component Acceptance Notice #5, File CA 88324.
