HCPL-4506-020E

Logic Output Optoisolators Overview

The HCPL-4506-020E is a single-channel logic output optocoupler from the Broadcom HCPL series, designed for intelligent power module interfaces. It features an open collector output with Schottky clamping to minimize storage time and enhance switching speed. The device provides high common-mode transient immunity of 15 kV/µs and supports data rates up to 1 MBd. Key electrical parameters include a maximum propagation delay of 650 ns, a forward voltage of 1.8 V, and a maximum continuous output current of 15 mA. It operates within a temperature range of -40°C to +100°C and offers isolation voltages of 3750 Vrms or 5000 Vrms depending on specific configuration.

Logic Output Optoisolators Feature Summary

• Schottky-clamped open collector output architecture reduces storage time for improved switching performance
• High common-mode transient immunity rated at 15 kV/µs ensures reliable signal integrity in noisy environments
• Optimized for intelligent power module interface applications requiring fast response times

Logic Output Optoisolators Applications

• Intelligent Power Module (IPM) interface circuits
• Industrial networking systems connecting diverse voltage levels
• Gate drive isolation for power electronics

Logic Output Optoisolators Procurement Notes

Verify the specific insulation voltage rating required for your application, as datasheets may list both 3750 Vrms and 5000 Vrms options. Confirm that the DIP-8 through-hole package aligns with your PCB layout constraints. Ensure the 15 mA maximum continuous output current meets the load requirements of your downstream logic circuitry before finalizing the component selection.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is needed for power control signals. The Schottky clamp feature makes it suitable for applications where minimizing turn-off delay is critical. Compare against standard phototransistor outputs if faster switching speeds are required. Verify that the 1 MBd data rate suffices for your system's communication frequency needs.

Logic Output Optoisolators Part Context

This part belongs to the HCPL series of logic output optocouplers manufactured by Broadcom Limited. It is specifically engineered for interfacing between low-voltage control logic and high-voltage power stages. The device replaces older discrete isolation solutions by integrating high-speed performance and robust noise immunity into a compact DIP-8 package.
