Data Sheet HCPL-181 Phototransistor Optocoupler SMD Mini-Flat Type Description Features The Broadcom HCPL-181 contains a light-emitting diode Current transfer ratio optically coupled to a phototransistor. It is packaged in a (CTR: minimum 50% at I = 5 mA, V = 5V) F CE 4-pin mini-flat SMD package with a 2.0-mm profile. The High input-output isolation voltage small dimension of this product allows significant space (V = 3750 Vrms) iso saving. The package volume is 30% smaller than that of High collector-emitter voltage (V = 80V) CEO conventional DIP type. Input-output isolation voltage is Response time 3750 Vrms. Response time, tr, is typically 4 s and minimum (t : typical, 4 s at V = 2V, I = 2 mA, R = 100) CTR is 50% at input current of 5 mA. r CE C L Mini-flat package (2.0-mm profile) in tape and reel Schematic package UL approved I I C 1 F 4 CSA approved ANODE COLLECTOR + IEC/EN/DIN EN 60747-5-2 approved V Options available: F IEC/EN/DIN EN 60747-5-2 approvals (060) 3 CATHODE EMITTER Applications 2 I/O interfaces for computers System appliances, measuring instruments Functional Diagram Signal transmission between circuits of different potentials and impedances PIN NO.
