PS2502L-4-A

Overview

The PS2502L-4-A is a Renesas Electronics transistor output optocoupler featuring four NPN photodarlington channels in a surface mount SMD-DIP-16 package. It provides an isolation voltage of 5000 Vrms and supports a maximum collector current of 160 mA per channel. The device operates with a minimum current transfer ratio of 200% at a forward current of 80 mA, with a typical forward voltage of 1.4 V. Electrical characteristics include a maximum collector-emitter saturation voltage of 1 V, rise and fall times of 100 µs each, and a reverse voltage rating of 6 V. Power dissipation is rated at 300 mW, with an operating temperature range from -55°C to +100°C.

Feature Summary

High isolation voltage capability of 5000 Vrms for robust circuit protection
Four-channel configuration utilizing NPN photodarlington outputs for high gain
Surface mount SMD-DIP-16 packaging suitable for automated assembly

Applications

Industrial control systems requiring multi-channel signal isolation
Power supply feedback loops for voltage regulation
Communication interface circuits for noise immunity

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's latest documentation to confirm pinout compatibility and RoHS status. Confirm that the NRND (Not Recommended for New Designs) status aligns with long-term procurement requirements. Ensure the SMD-DIP-16 footprint matches the PCB design specifications before finalizing orders.

Selection Notes

Select this component when high current drive capability via photodarlington outputs is required across multiple isolated channels. The 5000 Vrms insulation rating makes it suitable for applications demanding strict safety separation between low-voltage control logic and higher-voltage power stages. Consider the 100 µs switching speed limitations compared to faster transistor variants.

Part Context

This part belongs to the PS2502L series of Renesas transistor output optocouplers. It shares the family's core isolation architecture but differs from the PS2501L series by using photodarlington outputs instead of standard phototransistors, resulting in higher current transfer ratios but slower switching speeds. The '4' designation indicates a quad-channel configuration within the 16-pin package.
