TLP531(BL,F)

Transistor, Photovoltaic Output Optoisolators Overview

The TLP531(BL,F) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates a gallium arsenide infrared emitting diode with a phototransistor in a six-lead plastic DIP package. The device features a minimum collector-emitter voltage of 55 V and a minimum isolation voltage of 2500 Vrms. The BL rank specifies a minimum current transfer ratio of 100%. It operates within a temperature range of -25°C to 85°C.

Transistor, Photovoltaic Output Optoisolators Feature Summary

Optically couples an infrared LED to a phototransistor for signal transmission
Provides high electrical isolation between input and output circuits
Features internal base connection for enhanced EMI immunity

Transistor, Photovoltaic Output Optoisolators Applications

AC/DC input modules for programmable controllers
Solid state relay interfaces
Signal isolation in industrial control systems

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'BL' to confirm the 100% minimum current transfer ratio requirement. Ensure the DIP-6 package format matches the target PCB layout. Confirm RoHS compliance status as lead-based variants may exist depending on production date. Validate UL recognition file numbers if safety certification is required for the end application.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a high current transfer ratio is critical for logic level interfacing. The internal base connection makes it suitable for noisy environments requiring improved electromagnetic interference resistance. Compare against standard ranks if lower CTR suffices for cost optimization. Ensure the 55V collector-emitter voltage rating exceeds the maximum load voltage in the circuit design.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP53x series of transistor output optocouplers designed for general-purpose isolation. The TLP531 variant includes an internal base connection, whereas the TLP532 variant lacks this feature. Both share similar electrical characteristics but differ in noise performance due to the base configuration.
