LH1262CB

Transistor, Photovoltaic Output Optoisolators Overview

The LH1262CB is a dual-channel photovoltaic MOSFET driver manufactured by Vishay Semiconductor Opto Division. It consists of two LEDs optically coupled to two photodiode arrays, providing high-voltage isolation for gate drive applications. The device features a DIP-8 through-hole package and operates within a temperature range of -40°C to +100°C. Key electrical parameters include a forward voltage of 1.26 V, a reverse voltage of 5 V, and a maximum forward current of 50 mA. It offers an insulation voltage of 5300 Vrms with non-inverting configuration. The turn-on delay time is typically 35 µs, while the turn-off delay time is up to 90 µs.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Dual-channel photovoltaic output architecture using optically coupled LEDs and photodiode arrays
• High-voltage isolation capability rated at 5300 Vrms for safe signal transmission
• Non-inverting logic configuration suitable for direct gate drive interfacing
• Robust thermal performance supporting operation in extreme ambient temperatures

Transistor, Photovoltaic Output Optoisolators Applications

• Solid-state relay control circuits requiring galvanic isolation
• High-side MOSFET gate driving in power conversion systems
• Industrial motor control interfaces needing high voltage separation
• Inverter bridge drivers where noise immunity is critical

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'CB' corresponds to the through-hole DIP-8 package variant when ordering. Confirm that the required operating temperature range extends to +100°C, as this exceeds standard industrial limits. Ensure input current does not exceed 50 mA to maintain device integrity. Cross-reference the datasheet for exact pinout compatibility with existing PCB footprints before finalizing procurement decisions.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required without external bootstrap supplies. The photovoltaic output eliminates the need for negative gate voltages, simplifying circuit design. Consider the 35 µs turn-on delay for switching frequency limitations. Compare against surface-mount alternatives like the LH1262CACTR if board space constraints dictate SMD packaging instead of through-hole DIP-8.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the LH1262 series of photovoltaic MOSFET drivers from Vishay. It shares functional similarities with the LH1262CAC but differs in packaging and temperature rating. The series is designed to replace traditional transformer-coupled drivers in compact power electronics. It serves as a standalone solution for isolating low-voltage control signals from high-voltage power stages.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

The LH1262CACTR is a surface-mount equivalent offering identical electrical characteristics but in an SMD-8 package. Verify package footprint differences during replacement. No other direct substitutes are confirmed in public documentation.
