Overview
The CEL PS2702-1 is a single-channel optically coupled isolator featuring a Gallium Arsenide (GaAs) light-emitting diode and an NPN silicon Darlington-connected phototransistor. It provides high isolation voltage of 3750Vrms. Key electrical parameters include a minimum Current Transfer Ratio (CTR) of 200% at 1mA input current, with typical rise and fall times of 200µs each. The device supports DC input and has a maximum output voltage of 40V.
Feature Summary
- Integrates a GaAs LED with an NPN silicon Darlington phototransistor for high-gain signal transmission.
- Provides robust electrical isolation capability rated at 3750Vrms between input and output circuits.
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal interfacing between microcontrollers and high-voltage loads
Procurement Notes
Verify the specific suffix (e.g., -A, -F3-A, -V-A) to confirm package type, tape-and-reel configuration, and compliance status. Confirm product availability as some variants may be discontinued or have extended lead times. Ensure the selected variant matches the required isolation voltage and CTR specifications for the target application.
Selection Notes
Select this component when high gain is required due to the Darlington output structure. Consider the relatively slow switching speed (200µs) which limits suitability for high-frequency applications. Verify that the 40V output voltage rating meets the load requirements. Check for alternative packages if surface-mount space constraints exist.
Part Context
This part belongs to the PS2702 series of multi-photocouplers from California Eastern Laboratories (CEL). The series includes variants with different channel counts (1, 2, 4 channels) and output types. The PS2702-1 specifically denotes the single-channel configuration within this family of high-isolation voltage optoisolators.
Replacement Considerations
Direct replacements should be sought from the same PS2702 series or compatible Darlington output optocouplers with similar 3750Vrms isolation and 200% CTR. Verify pinout compatibility and SOP-4 package dimensions before substitution.
