Overview
The PS2702-1-F3-A is a high isolation voltage Darlington transistor optocoupler manufactured by CEL. It integrates a GaAs light-emitting diode with an NPN silicon Darlington-connected phototransistor in a plastic SOP package. Key electrical parameters include a maximum collector-emitter voltage of 40V, a minimum current transfer ratio (CTR) of 200%, and an isolation voltage of 3750Vrms. The device supports a maximum forward current of 50mA and a maximum collector current of 200mA.
Feature Summary
- High isolation voltage capability for robust signal transmission across isolated circuits
- Darlington output configuration provides high current gain and sensitivity
- Shielded SOP package design effectively blocks ambient light interference
Applications
- Digital telecommunications systems requiring signal isolation
- Medical equipment needing reliable galvanic isolation
- Industrial control systems utilizing high-density mounting
Procurement Notes
Verify the specific suffix F3-A against the official datasheet to confirm lead finish and packaging details. Ensure compatibility with RoHS standards if required. Cross-reference manufacturer part numbers from Renesas or Avnet to confirm secondary sourcing validity. Confirm operating temperature ranges match application requirements before procurement.
Selection Notes
Select this component when high current transfer ratio and strong isolation are critical. The Darlington structure suits applications demanding higher output drive capabilities compared to standard phototransistors. Consider the SOP package size for board space constraints. Verify input current limits do not exceed specified maximums during design.
Part Context
This component belongs to the PS2702 series of multi-photocouplers designed for high isolation applications. Manufactured originally by California Eastern Laboratories (CEL) and later associated with Renesas Electronics, it serves as a bridge between low-voltage digital logic and higher voltage loads. The series emphasizes reliability in noisy environments through optical coupling.
Replacement Considerations
Check for direct substitutes within the PS2702 family. Verify pinout compatibility and electrical specifications such as CTR and isolation voltage. Ensure the replacement package matches the SOP form factor for seamless integration without PCB redesign.
