TLP109(TPL,E

Overview

The TLP109(TPL,E is a high-speed optocoupler manufactured by Toshiba Semiconductor and Storage. It features a single channel with a transistor output type, housed in a 6-SO, 5-lead surface-mount package. The device provides an isolation voltage of 3750 Vrms and supports a data rate of 1 Mb/s. Key electrical parameters include a maximum forward current of 20 mA, a typical forward voltage of 1.64 V, and an output current of 8 mA. The current transfer ratio is specified at a minimum of 20% when tested at 16 mA. Switching performance includes rise and fall times of 800 ns. The component operates within a temperature range of -55°C to 125°C.

Feature Summary

• Integrates a GaAlAs light emitting diode with a high-speed photodiode-transistor chip for efficient optical coupling.
• Provides reinforced insulation compliance through guaranteed creepage and clearance distances exceeding 5.0 mm.
• Ensures stable digital signal transmission via guaranteed propagation delay time and switching time dispersion limits.

Applications

• Digital logic isolation between control circuits
• Isolation interfaces for Intelligent Power Modules (IPM)
• Motor control application circuits

Procurement Notes

Verify the specific suffix code against official Toshiba documentation to confirm exact packaging and tape specifications. Confirm RoHS compliance status and lead-free characteristics directly from the manufacturer's datasheet before procurement. Ensure the ordering quantity aligns with standard reel sizes if bulk purchasing is required. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity.

Selection Notes

Select this component when high-speed digital isolation is required alongside robust safety standards. The 3750 Vrms insulation rating suits applications demanding reinforced isolation barriers. The compact SOIC footprint facilitates dense surface-mount assembly. Consider the 800 ns switching speed for signal integrity requirements in motor drive or inverter control environments where fast response times are critical.

Part Context

This device belongs to the TLP109 series of high-speed optocouplers designed for industrial and automotive applications. It replaces older generations like the TLP112A, offering improved switching speeds and higher isolation voltages.
