Overview
The TLP185(GB-TPR,SE is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a GaAsP LED coupled to an NPN phototransistor within a compact SO-6 surface mount package. The device provides high isolation with a rated voltage of 3750Vrms for one minute. Key electrical parameters include a collector-emitter breakdown voltage (Vceo) of 80V and a maximum collector current of 50mA per channel. The typical rise time is 2µs and the fall time is 3µs at specified test conditions. The unit operates across a wide temperature range from -55°C to +110°C.
Feature Summary
- Provides galvanic isolation between input and output circuits using a GaAsP light emitting diode and NPN phototransistor configuration.
- Offers high insulation performance with a minimum isolation voltage rating of 3750Vrms.
- Designed for surface mount assembly in a small footprint SO-6 package suitable for automated PCB manufacturing.
Applications
- Industrial control system I/O interface isolation
- Switching power supply feedback loop isolation
- Microcontroller interfacing with high-voltage or high-current loads
Procurement Notes
Verify the specific suffix GB-TPR against the official Toshiba datasheet to confirm current transfer ratio grades and packaging specifications. Ensure that the ordering information matches the required tape and reel quantities if applicable. Cross-reference the component marking with the manufacturer's identification codes to prevent counterfeit parts. Confirm compliance with RoHS directives relevant to the production batch.
Selection Notes
Select this component when a single-channel transistor output isolator is required with moderate switching speeds. The 80V collector-emitter voltage rating supports standard logic level applications. Consider the CTR variations associated with the GB suffix compared to other variants like GR or GRH. Evaluate thermal management requirements given the 110°C maximum operating temperature limit.
Part Context
This part belongs to the TLP185 series of transistor output optocouplers from Toshiba. The series is characterized by its compact size and reliability for general-purpose signal transmission. Variants within the family differ primarily in current transfer ratio ranges and specific packaging options such as tube or reel configurations.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer for direct equivalents or cross-reference guides based on specific electrical parameter requirements.
