Product details

Single-channel 5000Vrms optocoupler with transistor output

The Toshiba TLP385(D4-GRL,E is a single-channel transistor-output optocoupler in a surface-mount package with 4 leads. It provides 5000Vrms of galvanic isolation between a DC input LED and a phototransistor output.

The 5000Vrms isolation rating covers reinforced insulation requirements for industrial equipment. The current transfer ratio (CTR) is specified at 100% minimum and 300% maximum when the LED forward current is 5mA.

Switching speed and temperature range

Rise and fall times are 2µs and 3µs typical, with turn-on and turn-off times both 3µs typical.

It is RoHS compliant.

Frequently asked questions

Is TLP385(D4-GRL,E suitable for high voltage isolation?

Yes, it is rated for 5000Vrms isolation, which meets reinforced insulation requirements for industrial equipment and power-supply feedback loops.

What is the equivalent of TLP385(D4-GRL,E?

The closest functional equivalent within the TLP385 family is the TLP385(D4-BL,E, which shares the same single-channel transistor output, 5000Vrms isolation, 100-300% CTR range, and 6-SOIC package. The suffix difference indicates a specific CTR bin or packaging variant — verify the exact CTR and package requirements before substituting.
