Overview
The PC123X1YFZ0F is a single-channel transistor output optocoupler manufactured by Sharp. It features an infrared emitting diode optically coupled to an NPN phototransistor in a 4-pin DIP package. Key electrical parameters include a maximum isolation voltage of 5 kVrms, a collector-emitter breakdown voltage of 70 V, and a typical rise time of 4 µs with a fall time of 3 µs. The device supports a maximum forward current of 50 mA and a maximum forward voltage of 1.4 V. Current transfer ratio ranges from 50% to 400% at an input current of 5 mA.
Feature Summary
- Provides reinforced insulation with high isolation voltage for safety-critical applications
- Offers fast switching speeds suitable for general-purpose signal transmission
- Features wide current transfer ratio range for flexible circuit design
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits between microprocessors and power devices
- Switching power supply feedback loops
Procurement Notes
Verify the specific suffix 'FZ' against official Sharp documentation to confirm lead frame material and plating specifications, as suffixes often denote packaging or material variations. Ensure the component matches the required agency approvals such as UL or VDE if used in certified equipment. Confirm availability status as some variants may be discontinued or subject to long lead times.
Selection Notes
Select this component when a standard NPN phototransistor output with 5 kVrms isolation is required. Consider the 70 V collector-emitter voltage limit for load compatibility. The 4-pin DIP form factor is suitable for through-hole mounting. Evaluate the 50-400% CTR range to ensure adequate noise margin for the specific application logic levels.
Part Context
The PC123 series is part of Sharp's lineup of DIP-type photocouplers designed for reinforced insulation. This series includes variants with different lead spacing and output types. The PC123X1YFZ0F belongs to the single phototransistor category, offering a balance of speed and sensitivity for general electronic isolation tasks.
Replacement Considerations
Official substitutes within the same family include PC123XNYSZ0F and PC123XNNSZ0F. Verify pinout compatibility and electrical parameter equivalence before substitution.
