PC123 Description

Short technical summary and product information.

The PC123 from Sharp Microelectronics is an optocoupler from the PC123 Series, comprising an IRED optically coupled to a phototransistor. This component is designed for I/O isolation of MCUs, noise suppression in switching circuits, and signal transmission between circuits with different potentials and impedances.

Key electrical specifications include an isolation voltage of 5000Vrms and a current transfer ratio (CTR) ranging from a minimum of 50% at 5mA input current to a maximum of 600% at 5mA. The typical forward voltage is 1.2V, with a maximum forward current of 0.05A. The output transistor can handle up to 70V and provides an output current of 50mA per channel. Rise and fall times are typically 4μs and 3μs, respectively.

Packaged in a 4-pin DIP with a 0.300" (7.62mm) lead spacing, the PC123 is suitable for through-hole mounting. It operates within a temperature range of -30°C to 100°C. The component is also available in wide-lead spacing and SMT gullwing lead-form options, offering flexibility in board design. Reinforced insulation and long creepage distance are additional features.

This device is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1. It is also noted as containing lead.
