TLP731(F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP731(F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an infrared emitting diode coupled to a silicon phototransistor within a DIP-6 package. The device provides high electrical isolation with a minimum insulation voltage of 4000Vrms. Key electrical parameters include a collector-emitter breakdown voltage (VCEO) of 55V, a maximum collector current (IC) of 50mA, and an absolute maximum forward current (IF) of 60mA. The current transfer ratio (CTR) ranges from 50% to 600% at IF=5mA and VCE=5V. It operates within a temperature range of -55°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation when ordering, as variations such as TLP731(GB,F) or TLP731(D4-GR-TP1,F) exist with different packaging or compliance attributes. Confirm availability status, as certain variants like TLP731D4(GB) are marked obsolete. Ensure the selected part matches the required lead time and manufacturing origin specifications.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component for applications requiring moderate speed and high isolation voltage in a through-hole package. Consider the TLP732 variant if a base connection is needed for improved noise immunity in high EMI environments. Verify that the load current requirements do not exceed the 50mA collector current limit and that the operating voltage remains below the 55V breakdown threshold.

Transistor, Photovoltaic Output Optoisolators Part Context

The TLP731 belongs to Toshiba's TLP series of general-purpose optocouplers designed for industrial and consumer electronics. It serves as a fundamental building block for isolating low-voltage control signals from higher-voltage power stages. The device is widely recognized for its reliability in maintaining signal integrity across electrically noisy environments while adhering to strict safety regulations.
