TLP184(V4GBTR,SE

Overview

The TLP184(V4GBTR,SE is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an infrared LED input coupled to a phototransistor output within a compact 6-SOP surface-mount package. Key electrical parameters include a collector-emitter voltage of 80V and a continuous collector current of 50mA per channel. The device provides high isolation with a rated insulation voltage of 3750Vrms. Typical switching characteristics consist of a turn-on time of 3µs and a turn-off time of 3µs. The current transfer ratio ranges from 100% to 600% at a forward current of 5mA. It operates across a wide temperature range from -55°C to 110°C.

Feature Summary

• Provides galvanic isolation between input and output circuits using an infrared LED and phototransistor configuration.
• Offers high-speed switching performance suitable for digital signal transmission applications.
• Ensures safety compliance through a robust 3750Vrms insulation voltage rating.

Applications

• Signal isolation in general-purpose digital communication interfaces
• Input stage isolation for microcontroller peripheral circuits
• Gate drive isolation for power switching devices

Procurement Notes

Verify the specific suffix (V4GBTR) against the manufacturer's latest datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the part number with official distributor catalogs to distinguish it from standard TLP184 variants that may differ in packaging or internal component tolerances.

Selection Notes

Select this component when a single-channel isolated interface is required with moderate speed capabilities. The 6-SOP package is appropriate for space-constrained printed circuit board designs. Consider the 100% minimum current transfer ratio for reliable logic level interfacing. Evaluate the 80V output voltage limit to ensure compatibility with downstream load requirements.

Part Context

This model belongs to the TLP184 family of transistor output photocouplers. It shares the fundamental optical architecture with other variants but differs in specific packaging configurations and manufacturing revisions indicated by the suffix. The V4GBTR designation typically denotes a specific reel-based packaging format intended for automated surface-mount assembly processes.

Replacement Considerations

Direct substitutes include TLP184(TPL,SE and TLP184(GB-TPR,SE. Verify that replacement parts maintain identical pin assignments and electrical ratings. Confirm that alternative sources offer equivalent isolation voltages and switching speeds to ensure circuit functionality remains unchanged.
