PS2805A-1-F3-A

Overview

The PS2805A-1-F3-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and utilizes an SSOP-4 surface-mount package. The device provides an isolation voltage of 2500 Vrms with a collector-emitter voltage rating of 70 V. Key electrical parameters include a forward current of 30 mA, a forward voltage of 1.4 V, and a power dissipation of 60 mW. The current transfer ratio ranges from 50% to 400%, while the rise and fall times are specified at 5 us and 7 us respectively. The operating temperature range extends from -55°C to +100°C.

Feature Summary

High isolation voltage capability for effective circuit separation
SSOP-4 compact surface-mount packaging suitable for dense layouts
NPN phototransistor output configuration for standard switching applications

Applications

Programmable logic controllers
OA equipment signal isolation
Measurement instrument interfaces

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status via official documentation before integration. Check current lifecycle status as some variants may be restricted for new designs. Ensure supply chain stability by validating distributor authorization. Review datasheet specifications thoroughly to match application requirements regarding thermal and electrical limits.

Selection Notes

Select this component when high isolation voltage and compact form factor are required for single-channel signal transmission. Consider the NPN output type for compatibility with standard logic interfaces. Evaluate the thermal performance within the specified operating temperature range. Compare current transfer ratio variations against system gain requirements. Assess package dimensions against PCB layout constraints for optimal placement.

Part Context

This part belongs to the PS2805A series of high-isolation optocouplers designed for AC input response applications. It shares architectural similarities with other members like the PS2805C-1 but differs in specific electrical ratings and certification options. The series targets industrial and commercial equipment requiring reliable galvanic isolation between control and load circuits.
