HCNW4506#300

Logic Output Optoisolators Overview

The Broadcom HCNW4506#300 is a single-channel logic output optocoupler featuring an AlGaAs infrared LED and an integrated photo-IC with open-collector, Schottky-clamped output. It provides 5000Vrms isolation voltage and a minimum common-mode transient immunity of 15kV/µs. The device operates within a temperature range of -40°C to +100°C. Key electrical parameters include a maximum forward current of 25mA, a typical forward voltage of 1.6V, and a continuous output current of 15mA. Propagation delays are specified at a maximum of 550ns for low-to-high and 400ns for high-to-low transitions.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '#300' against official datasheets to confirm package type and lead-free status, as distributor listings may vary in description accuracy. Ensure compliance with RoHS requirements if applicable to your manufacturing process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the 8-DIP gull-wing package matches your PCB footprint requirements before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed switching and robust noise immunity are required in isolated gate drive applications. The Schottky-clamped output reduces storage time, improving turn-off speed compared to standard open-collector outputs. Consider the 5000Vrms isolation barrier for safety-critical designs. Verify that the input current capabilities align with the driving circuit's output specifications to ensure reliable operation across the full industrial temperature range.

Logic Output Optoisolators Part Context

This device belongs to the HCNW series of intelligent power module interface optocouplers from Broadcom. It is functionally related to the HCPL-4506 and HCPL-J456 families, distinguished by its use of an AlGaAs LED rather than GaAsP. The #300 suffix typically denotes a specific tape-and-reel or tube packaging configuration, though physical dimensions remain consistent with the standard 8-DIP form factor used in these IPM interface solutions.
