OP524,005

Overview

The OP524,005 is a high-speed silicon photodiode manufactured by WeEn Semiconductors. It features a planar epoxy package designed for optical isolation applications. The device operates with a reverse voltage of up to 70 V and includes a built-in lens for efficient light collection. Key electrical parameters include a dark current of 1 nA at 70 V and a junction capacitance of 3 pF at 0 V reverse bias. The component supports a rise time of 8 ns and a fall time of 6 ns when driven by a 20 mA forward current pulse. It functions within a temperature range of -55 °C to +100 °C.

Feature Summary

• High-speed response suitable for digital signal transmission
• Integrated lens structure for optimized optical coupling
• Planar epoxy construction for environmental stability

Applications

• Optocoupler input devices
• Digital communication interfaces
• Signal isolation circuits

Procurement Notes

Verify the specific ordering code suffix against manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead-free material declarations prior to procurement. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet to maintain device reliability during assembly processes.

Selection Notes

Select this component based on required switching speed and optical coupling efficiency. Compare junction capacitance and rise/fall times against circuit bandwidth requirements. Verify that the operating temperature range meets the environmental constraints of the target application. Ensure compatibility with standard optocoupler pin configurations if used as a replacement part.

Part Context

This component belongs to the family of discrete photodetectors used primarily as the input stage in optoelectronic isolation devices. It is distinct from complete optocouplers, serving instead as a standalone photosensitive element integrated into larger assemblies or custom isolation modules.

Replacement Considerations

Direct replacements must match the pinout, package dimensions, and electrical characteristics such as responsivity and capacitance. Verify that substitute components offer equivalent rise and fall times to maintain signal integrity in high-speed applications.
