Overview
The PS2561DL2-1Y-F3-Q-A is a transistor output optocoupler manufactured by CEL, featuring a single channel in a 4-pin SMD package. It provides an insulation voltage of 5000 Vrms and utilizes an NPN phototransistor output. The device supports a forward current of up to 40 mA with a forward voltage of 1.4 V. Key electrical parameters include a collector-emitter saturation voltage of 300 mV maximum, a collector current of 50 mA, and a collector-emitter voltage of 80 V. The current transfer ratio ranges from 50% to 400%, with rise and fall times of 3 µs and 5 µs respectively.
Feature Summary
- High isolation voltage capability for safe signal transmission between circuits
- Compact surface-mount design suitable for space-constrained applications
- Fast switching performance with defined rise and fall time characteristics
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal interface between microcontrollers and high-voltage loads
Procurement Notes
Verify the specific suffix Q-A against official datasheets to confirm package type and compliance status. Confirm availability as some sources indicate discontinuation or limited stock. Ensure the supplier provides valid traceability documents matching the manufacturer's specifications before purchase.
Selection Notes
Select this component when high isolation voltage and compact SMD packaging are required. Compare current transfer ratio and switching speeds against application requirements. Verify that the NPN phototransistor output configuration matches the receiving circuit design needs.
Part Context
This part belongs to the PS2561 series of transistor output optocouplers. It is often associated with Renesas Electronics branding due to corporate acquisitions. The DL2 variant typically denotes a specific creepage distance and package style within the family.
Replacement Considerations
LTV-816S is listed as a similar substitute option. Verify pinout compatibility and electrical parameter equivalence before substitution.
