Overview
The TLP191B(MBSTPL,C,F is a photovoltaic output optocoupler manufactured by Toshiba Semiconductor and Storage. It features a GaAlAs infrared LED optically coupled to a series-connected photo-diode array with an integrated shunt resistor, designed for surface mount assembly in a 6-MFSOP package. Key electrical parameters include a minimum open voltage of 7.0V, a short-circuit current of 24µA (minimum), and a typical forward voltage of 1.4V. The device provides a minimum isolation voltage of 2500Vrms and holds UL recognition under file number E67349.
Feature Summary
- Integrates a GaAlAs infrared emitter with a photo-diode array and shunt resistor for direct MOS FET gate drive applications
- Provides high-voltage isolation capability suitable for safety-critical signal transmission
- Utilizes a compact mini flat outline form factor optimized for automated surface mount production
Applications
- MOS FET gate driver circuits
- Telecommunication equipment interfaces
- Programmable controller isolation stages
Procurement Notes
Verify the specific suffix codes (MBSTPL, C, F) against the official Toshiba datasheet to confirm packaging type, lead-free status, and reel specifications. Ensure the component matches the required isolation voltage rating of 2500Vrms for your circuit design. Cross-reference the UL file number E67349 if regulatory compliance documentation is required for your final product assembly.
Selection Notes
Select this component when a photovoltaic output is preferred over transistor or logic outputs for driving MOS gates without external pull-up resistors. Consider the 6-MFSOP package dimensions for PCB layout constraints. Evaluate the 24µA short-circuit current limit to ensure it meets the charging requirements of the target gate capacitance within the desired switching speed specifications.
Part Context
This part belongs to Toshiba's mini flat coupler series, which focuses on small-outline packages for surface mount technology. The TLP191B variant specifically utilizes a photo-diode array configuration, distinguishing it from standard phototransistor or IC-output optocouplers in the same family. This architecture allows for higher speed operation compared to bipolar transistor outputs while maintaining galvanic isolation.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative photovoltaic optocouplers by comparing pinout configurations, isolation voltage ratings, and photo-diode array characteristics.
