LTV-824S

Transistor, Photovoltaic Output Optoisolators Overview

The LTV-824S is a dual-channel transistor output optocoupler manufactured by Lite-On Inc. It features an NPN phototransistor output and is housed in an 8-pin SMD/SMT PDIP Gull Wing package. The device provides 5000 Vrms insulation voltage between input and output. Key electrical parameters include a maximum collector-emitter voltage of 35 V, a maximum collector current of 50 mA, and a typical rise/fall time of 18 µs. The forward voltage is 1.4 V with a maximum forward current of 50 mA. The current transfer ratio ranges from 50% to 600%. Power dissipation is rated at 200 mW, with an operating temperature range of -30°C to +100°C.

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Signal transmission across isolated ground planes
• Microcontroller interface circuits for noise immunity

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix TA1 or other variants if surface-mount reel packaging is required, as standard tubes may differ. Confirm RoHS compliance status through official datasheets. Ensure the 8-pin gull-wing package matches PCB footprint requirements. Check for UL and CSA certification marks if regulatory approval is mandatory for the end application.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is needed within a compact surface-mount form factor. The 5000 Vrms rating suits high-voltage separation needs. Compare current transfer ratio specifications against load requirements. Ensure the 18 µs switching speed meets the system's timing constraints. Verify thermal management capabilities given the 200 mW power dissipation limit.

Transistor, Photovoltaic Output Optoisolators Part Context

The LTV-824S belongs to the LTV series of photocouplers from Lite-On Technology Corporation. It is the surface-mount variant of the through-hole LTV-824. Both share similar electrical characteristics but differ in package type. The series is designed for general-purpose isolation tasks in consumer and industrial electronics.
