Overview
The PS2533L-1-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics. It integrates a GaAs infrared emitting diode with an NPN silicon photodarlington transistor in a DIP-4 Gull Wing package. Key electrical parameters include a collector-emitter voltage of 350 V, a maximum forward current of 80 mA, and an isolation voltage of 5000 Vrms. The device features a typical current transfer ratio range of 1500% to 6500%, with rise and fall times of 100 µs each.
Feature Summary
- High collector-to-emitter breakdown voltage capability for robust switching applications
- High isolation voltage rating ensuring safe signal transmission across potential barriers
- Integrated NPN photodarlington output providing high current gain
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission between microcontrollers and high-voltage circuits
Procurement Notes
Verify the specific suffix against official Renesas documentation to confirm package type and compliance status. Ensure the component matches the required isolation voltage and current transfer ratio specifications for the target circuit design before procurement.
Selection Notes
Select this component when high voltage isolation and moderate speed are required. Compare the CTR range and saturation voltage against circuit requirements. Consider thermal dissipation limits and operating temperature range during system integration.
Part Context
This part belongs to the PS2533 series of photocouplers. It is designed for general-purpose isolation tasks where high input-output isolation voltage is critical. The series offers various package options and performance variants to suit different industrial and commercial applications.
Replacement Considerations
Check for direct pin-compatible substitutes within the PS2533 family or equivalent devices from other manufacturers. Verify that replacement parts meet the same isolation voltage, CTR, and package dimensions.
