TLP628M(E

Transistor, Photovoltaic Output Optoisolators Overview

The TLP628M(E) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a DC input driving an NPN phototransistor output, housed in a standard 4-DIP package with a 0.300-inch (7.62mm) width. The device provides high isolation capability rated at 5000Vrms between input and output circuits. Key electrical parameters include a maximum collector-emitter voltage of 350V and a continuous output current of 50mA per channel. The typical forward voltage is 1.25V with a maximum forward current of 50mA. Current transfer ratio ranges from 50% to 600% at a forward current of 5mA. Switching characteristics include typical turn-on and turn-off times of 10µs each, with rise and fall times specified for signal integrity.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation when ordering, as variations such as GB or LF1 may indicate different packaging formats or compliance certifications while maintaining core functionality. Confirm RoHS status and moisture sensitivity levels against project requirements. Ensure the supplier provides official datasheets matching the exact part number to validate pinout and absolute maximum ratings before finalizing procurement decisions.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high voltage isolation is required alongside moderate switching speeds. The 350V output rating suits applications driving higher voltage loads directly. Compare current transfer ratio specifications against drive capabilities to ensure sufficient gain. Consider thermal management within the DIP-4 package if operating near maximum power dissipation limits in enclosed environments.
