Its primary job is to pass a logic-level or low-current signal across a galvanic isolation barrier rated at 5000Vrms, while protecting the low-voltage side from transients on the high-voltage side. The GRH suffix denotes a current transfer ratio (CTR) bin of 150% to 300% at a forward current of 5 mA — a middle-range rank that suits general-purpose isolation in industrial controls, PLC I/O modules, motor-drive feedback, and power-supply secondary-side monitoring. The output transistor can handle up to 80 V and 50 mA continuous, enough to drive a downstream logic input, a small relay coil, or a DC load directly. The 150% to 300% CTR range at 5 mA forward current means that with 5 mA through the LED, the output transistor can sink between 7.5 mA and 15 mA (collector current). That spread is wide enough that you size the pull-up resistor for the minimum CTR case to guarantee the output saturates — the 300mV Vce saturation figure at that current is the ceiling. If your design needs a tighter CTR window for consistent timing or load current, the TLP385 family offers other ranks: the GRL bin (lower CTR) or GB bin (higher CTR). The GRH sits in the middle, which is the default pick for most general-purpose isolation where you want reasonable LED current without over-driving the LED. ## Temperature range and environment Rated for -55°C to 110°C operating temperature, this optocoupler covers the full industrial temperature range and extends into the cold end that matters for outdoor telecom cabinets, solar inverters, and engine-bay electronics that see cold starts. ## Switching speed and timing Rise and fall times are 2 µs and 3 µs typical, with turn-on and turn-off times both at 3 µs typical.","metaTitle":"TLP385(GRH-TPR,E Toshiba Optocoupler, 5000Vrms, 150-300% CTR","metaDescription":"Toshiba TLP385(GRH-TPR,E single-channel transistor output optocoupler, 5000Vrms isolation, 150-300% CTR at 5mA, -55°C to 110°C, 6-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Surface Mount","Package / Case":"6-SOIC (0.173\\\", 4.40mm Width), 4 Leads","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5000Vrms","Vce Saturation (Max)":"300mV","Operating Temperature":"-55°C ~ 110°C","Rise / Fall Time (Typ)":"2µs, 3µs","Voltage - Output (Max)":"80V","Supplier Device Package":"6-SO, 4 Lead","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"300% @ 5mA","Current Transfer Ratio (Min)":"150% @ 5mA","Voltage - Forward (Vf) (Typ)":"1.25V","Turn On / Turn Off Time (Typ)":"3µs, 3µs","Current - DC Forward (If) (Max)":"50 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.54","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.54000","currency":"USD"},{"qty":10,"price":"$0.35500","currency":"USD"},{"qty":100,"price":"$0.23450","currency":"USD"},{"qty":1000,"price":"$0.18107","currency":"USD"},{"qty":3000,"price":"$0.16362","currency":"USD"},{"qty":6000,"price":"$0.15271","currency":"USD"},{"qty":15000,"price":"$0.14726","currency":"USD"},{"qty":30000,"price":"$0.14508","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/331d269fb9551bcaaac5f6b0e0ad3456.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the current transfer ratio (CTR) for TLP385(GRH-TPR,E?","answer":"The CTR is 150% minimum and 300% maximum, measured at a forward current of 5 mA.
