Broadcom 1 Channel Optocoupler SOIC-8 25mA 3.75kV

The Broadcom 1 Channel Optocoupler SOIC-8 25mA 3.75kV provides a 3.75kV isolation barrier between input and output circuits. It is a high-speed, single-channel optocoupler that uses a specialised insulating layer between an LED and an integrated photo-detector, helping to protect sensitive electronics from high voltages and electrical noise.

Overview

A key feature of this device is its separate connections for the photodiode bias and the output-transistor collector. According to the supplier, this design significantly reduces base-collector capacitance, which increases signal speed compared with conventional phototransistor couplers. The device is intended for applications where fast and accurate signal transmission is critical.

Key Features

• High-Speed Operation: Data rates up to 1Mbps, suitable for fast digital systems.
• TTL Compatibility: Open-collector output that is directly compatible with TTL logic levels, simplifying interface design.
• Operating Temperature Range: 0°C to 70°C, for use in varied environmental conditions.
• Isolation Voltage: 3.75kV isolation barrier to enhance safety and system protection in high-voltage applications.

Applications

This optocoupler is suited to isolating and interfacing in modern electronic systems. Typical uses include power module interfaces, motor drive control circuits, sensing instrumentation, and power management systems, providing a method for signal processing across isolated circuit domains.

Dimensions and Weight
