PS2502L-1-A

Overview

The PS2502L-1-A is a single-channel transistor output optocoupler from Renesas Electronics, featuring an NPN photodarlington output. It provides 5000 Vrms isolation voltage and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a minimum current transfer ratio of 200%, a maximum collector-emitter saturation voltage of 1 V, and a maximum collector current of 200 mA. The device supports a forward current of 80 mA with a forward voltage of 1.4 V. Switching characteristics specify rise and fall times of 100 µs each. It is housed in a DIP-4 package suitable for surface mount technology.

Feature Summary

High isolation voltage capability for safe signal transmission between circuits
NPN photodarlington output structure providing high current gain
Surface mount compatible packaging design

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops
Signal interface between microcontrollers and high-voltage loads

Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND) before integration into new products. Confirm RoHS compliance details through official manufacturer documentation. Ensure the specific suffix matches the required package and performance specifications. Cross-reference datasheet revisions to confirm parameter consistency. Validate supplier authenticity due to end-of-life status implications.

Selection Notes

Select this component when high current drive capability is required from a low-power input signal. The photodarlington output offers superior current transfer ratio compared to standard phototransistors. Consider the 100 µs switching speed limitation for high-frequency applications. Evaluate thermal dissipation requirements given the 300 mW power dissipation rating. Ensure the 5000 Vrms isolation meets system safety standards.

Part Context

This part belongs to the PS2502L series of transistor output optocouplers manufactured by Renesas Electronics. The series is designed for general-purpose isolation applications. The PS2502L-1-A specifically denotes the single-channel variant with photodarlington output. It shares common family characteristics such as isolation voltage and basic packaging style with other members like the PS2502L-4-A.
