Overview
The PS2501AL-1-H-A is a single-channel optoisolator manufactured by Renesas Electronics Corporation, belonging to the NEPOC series. It features a GaAs infrared LED input coupled to an NPN phototransistor output, providing 5000Vrms isolation voltage. The device utilizes a 4-SMD gull-wing package for surface mount installation. Key electrical parameters include a maximum collector-emitter voltage of 70V and a peak forward current of 30mA. The typical rise and fall times are 3µs and 5µs respectively, with a CTR range of 50% to 400% at 5mA input.
Feature Summary
- High isolation voltage capability of 5000Vrms between input and output circuits
- Compact 4-SMD gull-wing surface mount package design
- Fast switching performance with typical 3µs rise and 5µs fall times
- Wide current transfer ratio range for flexible drive requirements
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in noisy electrical environments
- Microcontroller interface circuits for safety isolation
- Power supply feedback loop isolation
Procurement Notes
Verify the specific suffix 'H' against the official Renesas datasheet to confirm lead frame material or reel specifications. Confirm the component status as Not Recommended for New Designs (NRND) impacts long-term availability. Ensure the 4-SMD gull-wing footprint matches the target PCB layout. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a compact SMD solution is required for single-channel isolation. The 70V output voltage rating suits low-voltage logic interfaces. Consider the NRND status for new projects; alternative newer generation isolators may offer better supply chain stability. Verify thermal management requirements within the -55°C to 100°C operating range.
Part Context
This part belongs to the Renesas PS2501 family of high-isolation optocouplers. The 'L' variant typically denotes lead-free construction, while 'A' indicates standard speed. The 'H' suffix often specifies tape and reel packaging or specific lead finish variations compared to the standard 'F3' or bare variants. It shares the same internal die and pinout as the PS2501AL-1-F3-A but differs in packaging format.
Replacement Considerations
PS2501AL-1-F3-A offers identical electrical characteristics in a standard tape-and-reel SMD package. PS2501-1-A provides the same functionality in a through-hole DIP package. PS2501L-1-A is a lead-free version in DIP format. Direct pin-to-pin replacements must maintain the 5000Vrms isolation and 4-SMD footprint compatibility.
