VISHAY 1-Channel Optocoupler, DIP, 4 Pin, 50mA, 5.3kV

The VISHAY 1-Channel Optocoupler is a high-performance 4-pin phototransistor output device with an AC input. It features a gallium arsenide (GaAs) infrared emitting diode that is optically coupled to a silicon planar phototransistor detector. This design ensures reliable signal transmission between two electrically separated circuits, making it an essential component for various electronic applications.

Key attributes of this optocoupler include a high current transfer ratio (CTR), low coupling capacitance, and a high isolation voltage of 5.3kV. It offers excellent CTR linearity depending on the forward current, alongside low CTR degradation over time. The device also boasts high common-mode interference immunity and low input current, which is particularly beneficial for energy-efficient designs.

Engineered for versatility, the coupler is end-stackable with a 2.54mm lead spacing and features creepage and clearance distances of greater than 8mm. It complies with IEC 60950 (DIN VDE 0805) standards for reinforced insulation, safely operating at voltages up to 400VRMS or DC. With a robust collector-emitter voltage of 55V and an operating ambient temperature range from -55°C to +100°C, it is well-suited for demanding environments, including battery-powered equipment and office machines.
