TLP184(TPR,E)

Overview

The TLP184(TPR,E) is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an infrared emitting diode coupled to a phototransistor within a compact SOIC-6 surface-mount package. The device provides high isolation with a rated insulation voltage of 3750 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a collector current capacity of 50 mA, and a forward current rating of 50 mA. Typical switching characteristics consist of a rise time of 2 µs and a fall time of 3 µs. The unit operates reliably across a temperature range from -55°C to +110°C.

Feature Summary

• Provides galvanic isolation between input control circuits and output load circuits using optical transmission.
• Features a phototransistor output capable of handling standard logic-level signals and moderate load currents.
• Designed for surface-mount assembly in a compact six-pin SOIC package to optimize board space.

Applications

• Signal isolation in industrial automation control systems
• Interface circuits for microprocessors and general-purpose logic devices
• Power supply feedback loops requiring voltage isolation

Procurement Notes

Verify the specific suffix (TPR,E) against the manufacturer's latest datasheet to confirm packaging format and compliance status. Confirm component lifecycle status as NRND before finalizing designs. Ensure ordering quantities align with reel specifications. Validate that the intended application environment falls within the specified operating temperature range.

Selection Notes

Select this component when a single channel of transistor output isolation is required with high voltage withstand capability. Consider the 80 V collector-emitter voltage limit for low-voltage signal switching applications. Evaluate the 50 mA collector current rating against load requirements. Compare switching speeds if higher frequency operation is necessary, as this device offers standard speed performance suitable for many digital interfaces.

Part Context

This part belongs to the TLP184 series of transistor output optocouplers. The series includes variants with different suffixes indicating variations in packaging or compliance certifications. These components are widely used in general-purpose isolation applications where cost-effective, reliable signal transfer across isolated boundaries is essential.

Replacement Considerations

Check for direct substitutes within the TLP184 family such as TLP184(TPL,SE). Verify pinout compatibility and electrical parameter equivalence before substitution. Consult official replacement lists for end-of-life transitions.
