Overview
The PS2561AL-1-V-H-A is a single-channel transistor output optocoupler manufactured by Renesas Electronics, part of the NEPOC series. It integrates a GaAs infrared emitting diode and an NPN silicon phototransistor in a lead-bending Gull-wing surface mount package (DIP-4). The device provides high isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to +100°C. Key electrical parameters include a collector-emitter breakdown voltage of 70 V, maximum forward current of 30 mA, and a typical current transfer ratio of 400%.
Feature Summary
- High isolation voltage capability for safe signal transmission between isolated circuits
- Surface mount Gull-wing package design for automated PCB assembly
- Integration of GaAs LED and NPN phototransistor for efficient optical coupling
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal interface between microcontrollers and high-voltage circuits
Procurement Notes
Verify manufacturer designation as Renesas Electronics, as NEC was acquired. Confirm the specific suffix indicates the lead-free Gull-wing variant. Check RoHS compliance status via official datasheets. Ensure the component matches the DIP-4 SMD package dimensions. Validate that the part number corresponds to the single-channel configuration.
Selection Notes
Select this component when surface mount technology is required for single-channel isolation. Consider the 400% current transfer ratio for high gain applications. Verify thermal management requirements given the 100°C maximum operating temperature. Compare against through-hole variants if soldering capabilities are limited. Ensure input current limits align with driving circuit specifications.
Part Context
This component belongs to the PS2561A family of photocouplers. The 'L' suffix denotes the lead-bending type, while 'V' and 'H-A' indicate specific packaging or tape/reel configurations. It is a successor to older NEC designs now managed under Renesas Electronics. The series is known for cost-performance balance in industrial isolation applications.
Replacement Considerations
Direct substitutes include PS2561AL-1-E3-A-L and PS2561AL2-1-E3-A from Renesas/NEC. Cross-brand equivalents may require verification of pinout and isolation voltage ratings. Ensure replacement parts maintain the same Gull-wing package footprint and electrical characteristics.
