PS2501-1-H-A

Overview

The CEL PS2501-1-H-A is a high isolation voltage single transistor type optocoupler. It contains a GaAs infrared emitting diode and an NPN silicon phototransistor. The device provides an insulation voltage of 5000 Vrms. It operates within a temperature range of -55°C to +100°C. The maximum power dissipation is 150 mW. The reverse voltage rating is 6 V. The package configuration is 4-DIP.

Feature Summary

• High isolation voltage capability for safe signal transmission between isolated circuits
• Optical coupling using GaAs LED and NPN phototransistor for reliable digital switching
• Wide operating temperature range suitable for demanding industrial environments

Applications

• Industrial automation control systems
• Power supply feedback loops
• Microprocessor input/output isolation

Procurement Notes

Verify the specific suffix 'H-A' against official Renesas or CEL documentation to confirm pinout and packaging variations. Confirm current lifecycle status as discontinued or NRND through authorized distributors. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when high isolation voltage is required in a compact DIP package. Compare CTR specifications against load requirements. Verify that the NPN output type matches the receiving circuit logic. Check thermal constraints relative to the 150 mW power dissipation limit.

Part Context

This part belongs to the PS2501 series of high isolation voltage photocouplers manufactured by CEL, now part of Renesas Electronics. The series includes variants like PS2501-1, PS2501L-1, and multi-channel versions. These devices are designed for general-purpose isolation applications requiring robust electrical separation.

Replacement Considerations

Check for direct substitutes such as PS2501-1 or PS2501L-1 from the same manufacturer family. Verify pin compatibility and electrical parameters before substitution.
