Overview
The PS2801-1-F3 is a single-channel transistor output optocoupler manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode and an NPN silicon phototransistor within a compact SSOP-4 package with a 1.27 mm pin pitch. The device provides high isolation voltage of 2500 Vrms and supports a maximum collector-emitter voltage of 80 V. Key electrical parameters include a typical forward current of 5 mA, a maximum collector current of 50 mA, and a power dissipation rating of 180 mW. Switching performance features a typical rise time of 3 µs and fall time of 5 µs. The unit operates within a temperature range of -55°C to +100°C.
Feature Summary
- High-speed switching capability with typical rise and fall times of 3 µs and 5 µs respectively
- Integrated shield effect in the SSOP package to block ambient light interference
- High collector-to-emitter voltage rating of 80 V for robust signal transmission
- Compliant with UL, BSI, and CSA safety standards for industrial applications
Applications
- Programmable logic controllers
- Measuring instruments
- Power supply circuits
- Hybrid IC designs
Procurement Notes
Verify component authenticity through authorized CEL distributors or certified suppliers. Confirm RoHS compliance status and specific safety certification numbers required for your region. Check for obsolescence notices as this series may have limited availability. Ensure storage conditions maintain moisture sensitivity levels before reflow soldering. Validate datasheet revisions match the production batch date code.
Selection Notes
Select this component when high-density PCB layouts require small form factors like SSOP-4. Choose based on the need for 2500 Vrms isolation between input and output circuits. Consider the 80 V collector voltage limit for driving loads. Evaluate the 50 mA maximum collector current against load requirements. Verify compatibility with standard surface mount assembly processes.
Part Context
This part belongs to the PS2801 family of high-isolation voltage photocouplers. The family includes variants such as PS2801-4 for four-channel applications. These devices are designed for high-density applications requiring optical isolation. The PS2801 series utilizes GaAs LEDs and NPN phototransistors for reliable signal transfer across isolation barriers.
