LTV-217-TP1-B-G

Transistor, Photovoltaic Output Optoisolators Overview

The LTV-217-TP1-B-G is a single-channel transistor output optocoupler manufactured by Lite-On Inc. It features a gallium arsenide infrared LED coupled to an NPN silicon phototransistor within a compact SOP-4 surface-mount package. The device provides high isolation voltage and is designed for applications requiring reliable signal transmission across isolated circuits. Key electrical characteristics include a minimum current transfer ratio of 50% at IF=5mA and VCE=5V, with a collector-emitter breakdown voltage of 80V. It operates within a temperature range of -55°C to +110°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'TP1' against official Lite-On documentation to confirm tape-and-reel packaging specifications and binning requirements. Ensure that the ordering part number matches the exact isolation and CTR grade required for the design. Cross-reference safety certification marks such as UL 1577 or VDE on the component marking to ensure regulatory compliance for end-use equipment.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a small footprint is critical for PCB real estate. The SOP-4 package offers a balance between isolation creepage distance and mounting density. Consider the 50% minimum CTR for driving standard logic loads. Verify that the 3750Vrms isolation rating meets the safety standards of the target application environment.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the LTV-217 series of transistor output optocouplers from Lite-On. The series is characterized by its dual-transmission molding technology which enhances environmental stability. Variants within the series differ primarily in Current Transfer Ratio (CTR) grades and packaging options, allowing designers to choose based on gain requirements and assembly methods.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include other LTV-217 variants with different CTR bins (e.g., LTV-217-A-G or LTV-217-C-G) if the electrical performance margins allow. Ensure any replacement maintains the same SOP-4 footprint and isolation voltage ratings.
