Overview
The TLP191B(TOJSTLUC,F) is a Toshiba Semiconductor and Storage optocoupler featuring a GaAlAs LED input coupled to a photo-diode array output. It provides 2500Vrms isolation voltage in a surface-mount package. The device supports a maximum forward current of 50mA and offers an open voltage of at least 7.0V with a short circuit current of minimum 24.0μA. Designed for MOS FET gate driving, it operates within a temperature range of -40°C to 85°C and complies with UL1577 standards.
Feature Summary
- Integrates a GaAlAs light emitting diode with a series-connected photo-diode array and shunt resistor
- Provides high isolation voltage suitable for safe signal transmission between circuits
- Optimized for direct MOS FET gate drive applications due to specific output characteristics
Applications
- MOS FET gate driver circuits
- Telecommunication systems
- Programmable controllers
Procurement Notes
Verify the exact suffix configuration against official Toshiba documentation to ensure correct packaging and tape specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure storage conditions meet moisture sensitivity level requirements to maintain component integrity during assembly.
Selection Notes
Select this component when a compact surface-mount solution is required for driving MOS FET gates with optical isolation. Consider its specific photo-diode array output characteristics rather than standard transistor outputs. Verify that the 2500Vrms isolation rating meets the system's safety requirements and that the operating temperature range aligns with the application environment.
Part Context
This part belongs to Toshiba's mini flat coupler series, designed specifically for surface mount assembly. It represents a specialized category of photocouplers utilizing a photo-diode array output instead of traditional transistors or triacs. This configuration allows for faster switching speeds and direct compatibility with MOS FET logic levels compared to standard phototransistor outputs.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult official Toshiba cross-reference guides for potential alternatives.
