Product details

High-CTR photocoupler for low-drive interfaces

The TLP2303(TPR,E is a single-channel DC-input transistor-output optoisolator from Toshiba, housed in a 5-lead 6-SOIC package. Its standout parametric is a minimum current transfer ratio of 500% at a forward current of just 5 mA.

3750Vrms isolation with 125°C ceiling

The 80 mA continuous output current per channel and 18 V maximum output voltage suit 5 V / 12 V logic-level interfaces and low-side switching of small relays or solenoids.

Active production — no obsolescence watch needed

Toshiba lists the TLP2303(TPR,E as Active and RoHS compliant.

Frequently asked questions

What is the input type and output type of TLP2303(TPR,E?

The input type is DC — the LED anode and cathode are brought out to pins, so you drive it with a forward current up to 20 mA max. The output is a phototransistor rated for 18 V max and 80 mA continuous. The 500% minimum CTR at 5 mA If means the output can sink at least 25 mA when the input LED is driven at 5 mA.
