Overview
The PS2533L-1-A is a single-channel transistor output optocoupler manufactured by CEL. It integrates a Gallium Arsenide (GaAs) infrared emitting diode with an NPN silicon Darlington phototransistor. The device provides high isolation voltage of 5000 Vrms and supports a maximum collector-emitter saturation voltage of 1 V. It operates within a temperature range of -55°C to +100°C, features a typical current transfer ratio of 2000%, and has a power dissipation rating of 150 mW.
Feature Summary
- Integrates a GaAs LED with an NPN silicon Darlington phototransistor for high-gain signal transmission
- Provides robust electrical isolation with a 5000 Vrms insulation voltage rating
- Designed for AC input applications requiring high collector-to-emitter voltage handling
Applications
- AC input sensing circuits
- Industrial control systems
- Power supply feedback loops
Procurement Notes
Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance details via the official datasheet. Check for specific ordering suffixes that may indicate package variations or environmental certifications. Ensure compatibility with existing PCB footprints before procurement.
Selection Notes
Select this component for applications requiring high current transfer ratios and strong isolation capabilities. The Darlington output structure offers higher gain compared to standard phototransistors. Verify thermal management requirements as power dissipation limits apply. Consider the operating temperature range for harsh environment deployments.
Part Context
This part belongs to the NEPOC series from California Eastern Labs (CEL), now part of Renesas Electronics. The PS2533L-1-A variant specifically denotes the lead-free version with specific packaging characteristics. It is part of a broader family of optocouplers designed for general-purpose isolation tasks in industrial and consumer electronics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with PS2533L-1-V-A or PS2533L-1-F3-A only if pinout and electrical specifications match exactly. Verify functional equivalence before substitution.
