TLP620-4(F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP620-4(F) is a quad-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates four independent GaAs infrared emitting diodes and NPN phototransistors within a single DIP-16 package. The device provides an isolation voltage of 5000 Vrms, ensuring robust electrical separation between input and output circuits. Key electrical parameters include a collector-emitter breakdown voltage of 55 V, a maximum forward current of 50 mA, and a typical current transfer ratio ranging from 50% to 600%. The unit supports AC and DC input signals with rise and fall times of approximately 2 µs and 3 µs respectively.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation against the manufacturer's latest datasheet to confirm pinout compatibility and regulatory approvals such as UL or VDE. Confirm whether the component is designated as recommended for new designs or obsolete, as availability may be limited. Ensure the selected variant matches the required packaging type and lead material specifications for your assembly process.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are required in a single footprint to reduce board space. Consider the 55 V collector-emitter voltage rating for low-voltage logic interfacing. Evaluate the current transfer ratio spread to ensure sufficient noise margin for your specific load requirements. Verify thermal dissipation capabilities if operating near maximum temperature limits.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP620 family of transistor output optocouplers, which also includes single-channel (TLP620) and dual-channel (TLP620-2) variants. The quad configuration distinguishes it by offering four isolated paths in a DIP-16 package, contrasting with the smaller packages used by its lower-channel counterparts. This family is designed for general-purpose isolation in industrial and communication systems.
