TLP2409(TP,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP2409(TP,F) is a MOSFET output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a GaAlAs infrared LED with a high-gain photo-MOSFET detector in a compact surface-mount package. The device provides electrical isolation between input and output circuits, featuring a single-channel configuration with SPST-NO (Form A) relay characteristics. Key electrical parameters include an insulation voltage of 5000 Vrms, a maximum forward current of 7.5 mA, and a load current capacity of 500 mA. The component supports AC and DC load voltages up to 60 V, with a typical on-resistance of 2 Ohms. It operates within a temperature range of -40°C to 85°C and utilizes a 4-SMD gull-wing package for reliable PCB mounting.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix TP,F against the manufacturer's official datasheet to confirm pinout orientation and reel specifications. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the insulation voltage and load current ratings with your system's operational requirements to guarantee adequate safety margins. Confirm compliance with relevant regional regulatory standards such as UL, VDE, or CQC if certification is mandatory for your end product.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a solid-state relay solution is needed for low-voltage AC or DC loads requiring high isolation. The 500 mA load current capability distinguishes it from lower-current variants in the TLP240 series. Consider the 2 Ohm on-resistance for power dissipation calculations in the output circuit. The wide operating temperature range makes it suitable for industrial environments where thermal stability is critical for consistent switching performance.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the TLP240 series of photorelays, which are designed for general-purpose switching applications. The series includes various models differentiated by load current, voltage ratings, and package types.
