PS2832-1-F3

Overview

The PS2832-1-F3 is a single-channel optoisolator manufactured by CEL, featuring a photovoltaic output configuration. It integrates a GaAs infrared emitting diode with an NPN silicon Darlington transistor array. The device provides high isolation voltage of 2500Vrms and supports a maximum collector-to-emitter voltage of 300V. Key electrical parameters include a current transfer ratio (CTR) of up to 4500% at 1mA input current, with typical rise and fall times of 20µs and 5µs respectively. It operates within a temperature range of -55°C to +100°C and dissipates up to 120mW.

Procurement Notes

Verify the manufacturer designation as CEL or NEC, as both entities have produced this component family. Confirm the package type is 4-SOP and check for RoHS compliance markings. Ensure the datasheet matches the specific suffix -F3 for tape and reel packaging if applicable. Cross-reference part numbers carefully to distinguish between similar PS2832 variants.

Selection Notes

Select this component when high voltage isolation and fast switching speeds are required in a compact SOP package. The high CTR ensures reliable triggering of downstream logic. Consider the thermal dissipation limits and operating temperature range during circuit design. Verify compatibility with input drive currents to maintain optimal performance within specified CTR ranges.

Part Context

The PS2832 series belongs to a family of multi-optocouplers designed for high isolation applications. Variants like PS2832-4 offer multiple channels, while PS2833 models may differ in pinout or internal configuration. This specific model represents a single-channel solution optimized for cost-effective isolation in space-constrained designs.

Replacement Considerations

Direct substitutes may include other single-channel Darlington output optocouplers from manufacturers like Toshiba or Renesas. Verify pin compatibility and electrical specifications such as isolation voltage and CTR before substitution.
