The HCPL-181 contains a light emitting diode opticallycoupled to a phototransistor. It is packaged in a 4-pin miniflat SMD package with a 2.0 mm profi le. The small dimensionof this product allows signifi cant space saving. The packagevolume is 30% smaller than that of conventional DIP type.Input-output isolation voltage is 3750 Vrms. Responsetime, tr, is typically 4 µs and minimum CTR is 50% at inputcurrent of 5 mA.
Current Transfer Ratio (CTR: min. 50% at IF = 5 mA, VCE = 5 V)
High input-output isolation voltage (Viso = 3750 Vrms)
High collector-emitter voltage (VCEO = 80 V)
Response time (tr: typ., 4 µs at VCE = 2 V, IC = 2 mA, RL = 100 Ω)
