TLP293-4(GB-TP,E

Transistor, Photovoltaic Output Optoisolators Overview

The TLP293-4(GB-TP,E is a quad-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates four independent phototransistor outputs with infrared emitting diodes in a single SOIC-16 surface-mount package. The device provides an insulation voltage of 3750 Vrms, ensuring robust signal isolation between input and output circuits. Key electrical specifications include a maximum collector-emitter voltage of 80 V, a collector current capacity of 50 mA per channel, and a forward voltage of approximately 1.4 V. Switching characteristics feature typical rise and fall times of 2 µs and 3 µs respectively, supporting efficient digital signal transmission.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Integrates four independent channels within a compact SOIC-16 surface-mount package for space-efficient circuit design.
• Provides high-voltage electrical isolation rated at 3750 Vrms to protect sensitive control circuits from noise and transients.
• Features fast switching performance with typical rise and fall times suitable for moderate-speed digital communication interfaces.

Transistor, Photovoltaic Output Optoisolators Applications

• Industrial automation systems requiring isolated digital signal transmission
• Communication equipment interface circuits for noise immunity
• Power supply control loops needing galvanic isolation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (GB-TP,E) matches the required tape-and-reel packaging configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or Toshiba sales representatives. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements to avoid additional handling fees or minimum order constraints.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are required in a single footprint. Compare against the TLP291-4 series if lower isolation voltage (2500 Vrms) is acceptable for cost reduction. Verify that the 50 mA collector current rating meets the load requirements of the downstream logic gates or microcontroller inputs without external amplification.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP293 family of transistor output optocouplers. It shares functional similarities with the TLP291-4 but offers higher isolation voltage ratings. The GB-TP,E suffix indicates specific packaging and environmental compliance attributes defined by Toshiba. It serves as a direct replacement for legacy quad-channel optocouplers in modern PCB layouts requiring enhanced safety standards.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

TLP293-4(V4LATRE) and TLP293-4(V4,E) are confirmed substitutes within the same product line offering identical electrical characteristics and pinout compatibility.
