LTV-352T-B

Transistor, Photovoltaic Output Optoisolators Overview

The LTV-352T-B is a single-channel phototransistor output optocoupler manufactured by Lite-On Inc. It features a Photodarlington output configuration housed in a compact SOP-4 (Mini-Flat) package with a 2.0mm pin pitch. The device provides an isolation voltage of 3750 Vrms and supports a maximum collector-emitter voltage of 300V. Key electrical parameters include a minimum current transfer ratio of 1000% and a maximum of 5000%, driven by a forward current up to 50mA. Typical switching times are 100µs rise and 20µs fall, with a power dissipation rating of 150mW.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest datasheet to confirm tape-and-reel orientation and halogen-free status. Ensure ordering quantities align with the specified reel multiples. Confirm that the SOP-4 footprint matches the target PCB design requirements before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high current gain is required due to its Photodarlington output structure. The 300V collector voltage rating makes it suitable for higher voltage isolation applications compared to standard 50V variants. Consider the slower switching speed relative to transistor outputs when designing for high-frequency digital signals.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the LTV series of photocouplers from Lite-On, designed for general-purpose isolation. The LTV-352T variant specifically emphasizes high CTR and voltage ratings within a small form factor. The '-B' suffix typically denotes specific packaging or environmental compliance variations within the product line.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes may include other high-CTR Photodarlington optocouplers in SOP-4 packages such as the PC817 series or HCPL-2601, provided they meet the 300V and 3750Vrms requirements. Verify pinout compatibility and thermal characteristics before substitution.
