TLP705AF(F)

Overview

The TLP705AF(F) is a photocoupler featuring an integrated gate driver, manufactured by Toshiba Semiconductor and Storage. It utilizes GaAlAs LED technology for optical coupling within a compact 6-lead SDIP surface-mount package. The device provides high-voltage isolation rated at 5000Vrms, suitable for demanding power switching environments. Operating temperature range spans from -40°C to 100°C. This component is designed to offer reliable galvanic isolation between control circuits and high-power loads.

Feature Summary

• Integrates a GaAlAs light emitting diode with an optimized photodetector for efficient signal transmission
• Provides robust electrical isolation capability rated at 5000Vrms for safe high-voltage operation
• Features a compact 6-lead SDIP gull-wing surface mount package design

Applications

• High-voltage switching applications requiring galvanic isolation
• Industrial motor drive systems
• Power supply control circuits

Procurement Notes

Verify current availability status as the TLP705AF(F) is listed as obsolete or discontinued in multiple distributor databases. Confirm end-of-life notifications and product discontinuance details directly with Toshiba Semiconductor and Storage before finalizing procurement plans. Ensure alternative sourcing strategies are prepared due to limited stock availability.

Selection Notes

Select this component when a compact, optically isolated gate driver with 5kV isolation rating is required. Consider the 6-lead SDIP package constraints and surface mount mounting type. Evaluate thermal performance within the specified -40°C to 100°C operating range. Verify compatibility with existing PCB layouts and isolation voltage requirements of the target application circuit.

Part Context

This part belongs to the TLP705 series of optically isolated gate drivers. It represents a miniaturized version compared to traditional 8-pin DIP packages, offering a 50% size reduction while maintaining essential isolation features. The series is designed for applications needing reliable signal transfer across high potential barriers in power electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require consulting Toshiba's official obsolescence notices or evaluating generic equivalents with matching 5kV isolation and 6-lead SDIP specifications.
