Overview
The PS2501-1-Q-A is a high-voltage optoisolator from the Renesas NEPOC series, featuring a single channel with an NPN phototransistor output. It provides galvanic isolation up to 5000Vrms between input and output circuits. The device integrates a GaAs infrared LED and operates within a temperature range of -55°C to +100°C. Key electrical characteristics include a maximum collector-emitter voltage of 80V, a DC forward current of 30mA, and a typical rise/fall time of 3µs/5µs. It is housed in a 4-DIP package suitable for through-hole mounting.
Feature Summary
- Provides galvanic isolation between circuits using a GaAs LED and NPN phototransistor configuration
- Designed for high-voltage applications with robust insulation capabilities
- Features fast switching speeds suitable for digital signal transmission
Applications
- Industrial control systems requiring circuit isolation
- Power supply feedback loops for safety isolation
- Microcontroller interface circuits for noise immunity
Procurement Notes
Verify the specific suffix 'Q' indicates automotive or qualified grade requirements against the official datasheet. Confirm package dimensions and pinout compatibility with existing PCB footprints. Check for recent Product Change Notifications (PCN) regarding manufacturing site or material changes. Ensure compliance with relevant industry standards if used in regulated environments.
Selection Notes
Select this component when high isolation voltage and reliable digital switching are required. Compare CTR specifications against load requirements to ensure sufficient output drive. Consider thermal management within the specified operating temperature range. Verify that the DIP package style aligns with assembly processes compared to surface-mount alternatives.
Part Context
This part belongs to the PS2501 family of optocouplers manufactured by Renesas Electronics. The family includes variants such as PS2501-1-A and PS2501L-1, differing primarily in packaging and qualification levels. The PS2501 series is widely recognized for its reliability in industrial and consumer electronics applications requiring electrical isolation.
Replacement Considerations
Direct substitutes may include PS2501-1-A for general purpose use, though qualification differences exist. Cross-reference with other 5000Vrms single-channel transistor output optocouplers from manufacturers like Broadcom or Vishay if Renesas supply is limited. Ensure functional equivalence in isolation voltage and package type.
