Product details

Isolation barrier and CTR window

The TLP385(BLL-TPR,E is a single-channel transistor-output optocoupler from Toshiba Semiconductor, rated for 5000Vrms isolation between input and output — enough for reinforced isolation in mains-referenced circuits like PLC digital inputs or motor-drive feedback interfaces. The current transfer ratio (CTR) spans 200% to 400% at a forward current of 5mA, which means the output transistor can sink at least twice the input current across the full temperature range. That gain margin is what lets you drive a 5V logic input with a 5mA LED current and still have headroom for CTR degradation over life.

Lifecycle and supply posture

Toshiba lists the TLP385(BLL-TPR,E as Active with RoHS compliance. The part is supplied in Tape & Reel (TR) or Cut Tape (CT) options, surface-mount in a 6-SO, 4-lead package. Sourced to order against your BOM quantity; current pricing and lead time confirmed at quote time.

Frequently asked questions

What is the CTR range of TLP385(BLL-TPR,E and is it suitable for 5V logic?

The CTR is 200% minimum and 400% maximum at a forward current of 5mA. With a typical Vf of 1.25V at that drive, the LED side is easily driven from a 3.3V or 5V logic output through a series resistor. The 80V collector rating and 50mA output current give ample margin for 5V logic levels.
