ON Semiconductor H11F3 Product Overview

The H11F3 from ON Semiconductor is a versatile and reliable optoelectronic device designed to offer electrical isolation between input and output functions in a wide array of electronic applications. This device falls under the category of Photo FET Optoisolators, which are known for their ability to allow a signal to pass from one circuit to another while maintaining a high degree of electrical isolation.

Featuring a gallium arsenide infrared emitting diode, which is optically coupled to a silicon planar photodarlington detector, the H11F3 ensures a robust and efficient transfer of electrical signals. The photodarlington response amplifies the input signal, providing a higher current transfer ratio compared to standard phototransistors.

The H11F3 is encapsulated in a six-pin dual-in-line package, which is compact and suitable for through-hole mounting, making it easy to integrate into a variety of circuit boards. Its high isolation voltage of typically 5300Vrms provides excellent protection against high voltage transients and ensures safe operation even in challenging electrical environments.

Key features of the H11F3 include:

• High Current Transfer Ratio (CTR)
• High Input-to-Output Isolation Voltage (5300Vrms)
• Low LED Trigger Current
• High Output Voltage (30V)
• Standard DIP Package

This optoisolator is commonly used in applications such as signal switching, AC/DC input isolation, telephone ring detection, and ground loop elimination. Its ability to efficiently transmit signals across electrical barriers makes it invaluable in applications where signal integrity and isolation are critical.

The H11F3 is a testament to ON Semiconductor's commitment to providing high-quality components that enhance the reliability and functionality of electronic systems. Whether you are designing industrial control systems, medical equipment, or consumer electronics, the H11F3 offers a solution that combines performance with peace of mind.
