Overview
The PS2501AL-1-F3-A is a single-channel transistor output optocoupler manufactured by CEL, part of the Renesas NEPOC series. It integrates a GaAs infrared LED and an NPN silicon phototransistor in a 4-SMD gull-wing package. Key electrical parameters include a 5000 Vrms isolation voltage, 70 V maximum collector-emitter voltage, and 30 mA maximum collector current. The device operates within a temperature range of -55°C to +100°C with a power dissipation of 150 mW.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.
- Features a compact surface-mount design suitable for automated assembly processes.
- Utilizes an NPN phototransistor output for digital logic interfacing and signal transmission.
Applications
- Digital logic signal transmission and level shifting
- Power supply control and switching circuits
- Electrical insulation between circuit stages or systems
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status via the specific datasheet revision. Check for obsolescence notices as this component may be subject to lifecycle changes. Ensure packaging specifications match project requirements for surface-mount assembly.
Selection Notes
Select this component when high isolation voltage is required in a small footprint. Consider the 5000 Vrms rating for safety-critical applications. Evaluate the CTR range and switching speeds against system timing requirements. Compare thermal performance within the specified operating temperature range.
Part Context
This device belongs to the PS2501A family of optocouplers designed for general-purpose isolation. The 'L' suffix typically denotes enhanced isolation characteristics compared to standard variants. The F3-A suffix indicates specific packaging and tape-and-reel configuration for SMD mounting.
Replacement Considerations
Direct substitutes include PS2501AL-1-F3-H-A from Renesas/CEL. Verify pinout compatibility and electrical parameter equivalence before substitution. Cross-reference datasheets for any differences in isolation voltage or current transfer ratio.
