PS2932-1-A

Overview

The PS2932-1-A is a Darlington output optocoupler featuring a single element with 2500V isolation. It utilizes an ultra-small plastic package measuring 4.60 x 2.50 mm with a height of 2.10 mm. Key electrical parameters include a maximum collector-emitter breakdown voltage of 300 V, a nominal current transfer ratio of 2000%, and a maximum forward current of 0.05 A. The device operates within a temperature range of -55 °C to 100 °C and includes built-in diode and resistor configurations.

Feature Summary

• Ultra-small flat-lead package design for high-density mounting applications
• High collector-to-emitter voltage capability for robust isolation
• Built-in diode and resistor configuration for simplified circuit integration

Applications

• High density mounting applications requiring compact isolation
• Industrial control systems utilizing small form factor components
• Equipment requiring high voltage isolation in limited space

Procurement Notes

Verify the specific suffix (e.g., -A, -F3) against official datasheets to confirm packaging type and reel specifications. Ensure compliance with RoHS standards and safety certifications such as UL recognition and VDE approval are required for the target application environment.

Selection Notes

Select this component when space constraints necessitate an ultra-small footprint while maintaining high isolation voltage. The Darlington output provides high gain suitable for driving loads directly. Confirm thermal limits and current transfer ratio requirements match the system design before finalizing the part number.

Part Context

This component belongs to the NEPOC series of photocouplers manufactured by NEC/CEL. It represents an evolution from the PS28xx series, offering a significant reduction in mounting area. The device integrates a GaAs LED and NPN silicon phototransistor for efficient optical coupling.

Replacement Considerations

Direct substitutes may include other parts from the PS2932 or PS2933 families depending on voltage and pinout compatibility. Verify package dimensions and isolation distances when cross-referencing with alternative manufacturers' offerings.
