PS2535L-1-A

Overview

The PS2535L-1-A is a single-channel transistor output optocoupler manufactured by CEL. It features an NPN Photodarlington output and provides 5000 Vrms insulation voltage. The device supports SMD/SMT installation in a Reel or Cut Tape package. Key electrical parameters include a collector-emitter saturation voltage of 1 V maximum, a forward current of 50 mA, and a forward voltage of 1.4 V. It operates within a temperature range of -55°C to +100°C with a power dissipation of 70 mW.

Feature Summary

High isolation voltage capability for safe signal transmission across isolated circuits
NPN silicon darlington connected phototransistor output for high current transfer ratio
Gull-wing lead bending model designed for surface mount applications

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops
Signal isolation in microprocessor interfaces

Procurement Notes

Verify the manufacturer designation as CEL or Renesas Electronics, as both entities have produced this component family. Confirm the specific suffix indicates the Gull-wing lead form factor suitable for surface mount technology. Ensure the datasheet matches the required insulation voltage and current transfer ratio specifications for your circuit design.

Selection Notes

Select this component when high collector-to-emitter voltage handling and robust isolation are required in a surface-mount footprint. The NPN Darlington output offers high gain, making it suitable for driving loads directly from low-current logic signals. Consider the thermal limits and packaging type during PCB layout.

Part Context

This part belongs to the PS2535L series of optically coupled isolators. The series includes variants like PS2535-1 (DIP) and PS2535L-1 (SMD). These devices integrate a GaAs light emitting diode with an NPN silicon darlington phototransistor to provide electrical isolation between input and output circuits.
