Overview
The PS2501L-4-E3-A is a quad-channel transistor output optocoupler manufactured by Renesas Electronics. It features an NPN phototransistor output and provides 5000 Vrms isolation voltage. The device operates within a temperature range of -55°C to +100°C. Key electrical parameters include a maximum collector-emitter voltage of 80V, a maximum collector current of 50mA, and a forward current of 80mA. The current transfer ratio ranges from 80% to 600%. Typical switching times are 3µs for rise time and 5µs for fall time.
Feature Summary
- Contains four independent channels for multi-signal isolation
- Utilizes GaAs LED and NPN silicon phototransistor technology
- Provides high insulation voltage capability
Applications
- Industrial automation control systems
- Power supply feedback circuits
- Signal isolation in measurement equipment
Procurement Notes
Verify the RoHS compliance status through official Renesas documentation or authorized distributor datasheets before procurement. Confirm that the specific suffix matches the required package and lead-free specifications. Ensure compatibility with existing design constraints regarding channel count and isolation requirements.
Selection Notes
Select this component when multiple isolated channels are required in a single package. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the CTR range and switching speeds against system timing requirements. Verify thermal management needs given the operating temperature range.
Part Context
This part belongs to the PS2501L series of quad-channel optocouplers. It shares architectural similarities with the PS2501-4 but differs in packaging and specific electrical characteristics. The series is designed for general-purpose isolation tasks requiring compact footprint and reliable performance.
Replacement Considerations
Check for direct pin-compatible substitutes within the PS2501L family. Verify if alternative manufacturers offer equivalent quad-channel devices with matching isolation ratings and CTR specifications.
