It accepts a DC input on the LED side and delivers a switched transistor output on the detector side, with a reinforced 5000 Vrms isolation barrier between the two domains. The GR binning in the order code specifies a current transfer ratio (CTR) of 100% minimum and 300% maximum at a forward current of 5 mA, which provides a well-defined gain window for the designer to budget LED drive current across temperature and device lifetime. The output transistor can switch up to 80 V and sink 50 mA continuous, with a saturation voltage of 300 mV maximum — sufficient for driving logic inputs, small relays, or DC loads in a 5 V or 3.3 V system. ## Switching speed — what the 2 µs rise / 3 µs fall means It will handle 10–100 kHz PWM signals, slow serial data (a few kbps), or relay-coil drive without issue. For applications requiring faster edge rates — such as CAN, RS-485, or high-speed digital isolators — a dedicated digital isolator or high-speed optocoupler would be the better fit. ## Package and temperature range Housed in a 4-lead SO-6 surface-mount package (6-SOIC with 0.173\" body width, 4.40 mm), the TLP385(GR-TPR,E occupies a compact footprint suitable for dense PCB layouts. Cut Tape (CT) options are also available for prototype or low-volume builds. ## Lifecycle and compliance It is RoHS compliant, which simplifies procurement for designs targeting EU or other regulated markets.","metaTitle":"TLP385(GR-TPR,E Toshiba Optocoupler, 5000Vrms, 1-Ch DC Input","metaDescription":"Toshiba TLP385(GR-TPR,E single-channel transistor-output optocoupler in 4-lead SO-6 package. 5000Vrms isolation, 100-300% CTR at 5 mA.
