Overview
The PS2561BL-1-Q-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and operates within a temperature range of -55°C to +100°C. The device provides 5000 Vrms insulation voltage and utilizes a DIP-4 Gull Wing surface mount package. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 30 mA, and a power dissipation of 150 mW. The forward voltage is specified at 1.2 V with a forward current of 10 mA.
Feature Summary
- Provides galvanic isolation between input and output circuits via optical transmission.
- Features an NPN phototransistor output for digital signal switching applications.
- Designed for high-temperature operation up to 100°C in compact surface-mount packaging.
Applications
- Industrial control systems requiring isolated signal interfaces
- Power supply feedback loops for voltage regulation
- Microcontroller input/output isolation in embedded systems
Procurement Notes
Verify the specific suffix 'Q' against official Renesas documentation to confirm automotive qualification status or specific reliability standards, as standard datasheets may not explicitly detail all suffix variations. Confirm RoHS compliance and end-of-life status through authorized distributors before procurement planning.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation with moderate speed requirements. Ensure the 70 V collector-emitter voltage rating meets the load requirements. Compare against through-hole variants if PCB space allows for potentially lower cost options.
Part Context
This part belongs to the PS2561B series of transistor output optocouplers. The series is characterized by high isolation voltage and compatibility with standard logic families. The 'L' suffix typically indicates lead-free composition, while 'Q' often denotes specific quality or automotive grades depending on manufacturer coding conventions.
Replacement Considerations
Direct substitutes include PS2561BL-1-A and PS2561AL-1-V-A from the same manufacturer family. Verify pinout compatibility and electrical parameter margins before substitution.
