Broadcom 2-Channel SMD Optocoupler DIP-8 50mA 5kV

The Broadcom 2-Channel SMD Optocoupler is a DC-input, dual-channel phototransistor isolator supplied in an 8-pin surface-mount DIP package. It provides electrical isolation between input and output circuits, helping to protect sensitive components from voltage spikes and ground loop currents while supporting reliable signal transmission with reduced noise.

Key Features

• Two channels in a compact surface-mount DIP-8 package
• Isolation voltage of 5 kV (5000 V RMS) for applications requiring safety barriers
• Minimum current transfer ratio (CTR) of 130% for efficient signal coupling
• Typical response time of 4 µs to support high-speed data transmission
• Phototransistor output with a 70 V collector-emitter voltage rating
• Approvals from CSA, UL 1577 and IEC/EN/DIN EN 60747-5-2

Applications

This optocoupler is suited to modern digital and industrial electronics. Typical uses include programmable logic controller (PLC) I/O interfaces, computer peripherals, sequence controllers and system appliances. It is also used in measuring instruments and for transmitting signals between circuits of differing potentials and impedances, providing clean and isolated communication channels.

Design and Dimensions

The device is encased in an 8-pin surface-mount DIP (Dual In-line Package), offering a compact footprint for PCB design. Package dimensions are 4.3 mm x 3.3 mm x 1.5 mm (height, width and depth), with a product weight of 9.072 gm.
