Overview
The TLP185(BLL-TL,SE is a single-channel transistor output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an aluminum gallium arsenide infrared LED with a phototransistor in a compact SO-6 surface-mount package. The device provides electrical isolation with a minimum isolation voltage of 3750Vrms. It features a collector-emitter breakdown voltage of 80V and supports a maximum forward current of 20mA. The unit weight is 80mg, and it operates within a temperature range of -55°C to 110°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using an infrared LED and phototransistor configuration.
- Designed for surface-mount technology (SMT) installation in a small SO-6 package footprint.
- Complies with RoHS standards for environmental safety and regulatory adherence.
Applications
- Office equipment signal transmission
- Programmable logic controller (PLC) interfaces
- AC/DC input module isolation
- Telecommunications equipment
Procurement Notes
Verify the specific suffix 'BLL' against the official Toshiba datasheet to confirm the exact Current Transfer Ratio (CTR) binning and performance grade. Ensure the ordering part number matches the required packaging format, such as cut tape or reel, as indicated in distributor specifications. Confirm that the component meets all necessary safety certifications for the target application environment before finalizing procurement.
Selection Notes
Select this component when a low-cost, general-purpose optocoupler with moderate speed and high isolation voltage is required. The BLL suffix indicates a specific CTR range; verify if this gain level suits the load requirements compared to other variants like GB or GR. Consider the SO-6 package size constraints and the 20mA maximum forward current limit when designing the drive circuitry for the internal LED.
Part Context
This component belongs to the TLP185 series of small flat couplers designed for SMT applications. The series includes various suffixes denoting different CTR grades and packaging options. The TLP185 family is widely used for noise suppression and signal transmission in industrial and consumer electronics where galvanic isolation is critical for system safety and reliability.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Toshiba's official cross-reference guides or contact technical support directly to identify equivalent components with matching electrical characteristics and pin configurations.
