TLP620-2(D4-TP1,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP620-2(D4-TP1,F) is a transistor output optocoupler featuring two isolated channels within an eight-lead plastic DIP package. It consists of inverse parallel-connected gallium arsenide infrared emitting diodes optically coupled to photo-transistors, enabling AC or DC input operation. Key electrical parameters include a minimum collector-emitter breakdown voltage of 55 V and a minimum current transfer ratio of 50%. The device supports a maximum forward current of 50 mA and offers a high isolation voltage rating of 5000 Vrms. Operating temperatures range from -25 °C to 85 °C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel configuration with independent isolation for each channel
• Inverse parallel LED structure allows direct AC signal input without external rectification
• High insulation voltage capability ensures safe signal transmission across potential barriers

Transistor, Photovoltaic Output Optoisolators Applications

• AC/DC input module interfaces in industrial control systems
• Signal isolation in communication network equipment
• Microcontroller input buffering for digital logic level translation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (D4-TP1,F) against official Toshiba Semiconductor and Storage documentation to confirm tape-and-reel packaging and compliance status. Ensure the component matches the required DIP-8 through-hole mounting specifications. Cross-reference safety approvals such as UL and VDE if used in certified end-products. Confirm that the manufacturer designation aligns with current corporate naming conventions.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a single package footprint. The inverse parallel input design simplifies circuitry for AC applications by eliminating external diodes. Consider the 55 V collector-emitter voltage limit for low-voltage switching tasks. Verify that the 50 mA forward current rating meets the drive requirements of the connected load or subsequent stage.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP620 series of transistor output optocouplers manufactured by Toshiba Semiconductor and Storage. The series includes variants with one, two, or four channels, packaged in DIP formats. The TLP620-2 specifically provides two channels in an 8-pin DIP, distinguishing it from the single-channel TLP620 and the quad-channel TLP620-4.
