PS2501-1-Q-A

Overview

The PS2501-1-Q-A is a single-channel transistor output optoisolator manufactured by CEL. It features an NPN phototransistor output with a maximum collector-emitter voltage of 80V and a collector current of 50mA. The device provides high isolation with a rated insulation voltage of 5000Vrms. It operates within a temperature range of -55°C to 100°C and is housed in a 4-DIP package.

Feature Summary

• High isolation voltage rating for safe signal transmission between isolated circuits
• Single channel configuration with NPN phototransistor output stage
• Wide operating temperature range suitable for industrial environments

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Microcontroller input/output isolation

Procurement Notes

Verify the specific suffix 'Q-A' against official datasheets to confirm qualification status, as standard variants may differ. Confirm availability through authorized distributors, noting that this component may be discontinued or restricted in certain regions. Ensure compliance with RoHS directives if required for the target application.

Selection Notes

Select this component when a single-channel isolation solution with 5000Vrms capability is needed. Compare CTR specifications against circuit requirements. Verify package compatibility with PCB layout constraints. Consider thermal management needs given the 150mW power dissipation limit.

Part Context

This part belongs to the PS2501 series of high-isolation optocouplers from CEL. The series includes various channel counts and package options. The PS2501-1 variant specifically denotes a single-channel device. The Q-A suffix typically indicates specific qualification or packaging variations within the product line.

Replacement Considerations

PS2501-1-F3-A is listed as a potential replacement by Renesas Electronics, though it is marked as Not Recommended for New Designs (NRND). Verify pinout and electrical parameters before substitution.
