ACPL-W483-000E

Overview

The ACPL-W483-000E is a high-speed logic output optocoupler from Broadcom Limited, designed for Intelligent Power Module (IPM) applications. It features an AlGaAs LED and photodetector with a built-in Schmitt trigger. The device provides 5000 Vrms isolation voltage and supports a maximum continuous output current of 50 mA. Key electrical parameters include a rise time of 6 ns, fall time of 6 ns, forward voltage of 1.5 V, and power dissipation of 210 mW. It operates within a temperature range of -40°C to +105°C and is housed in a SOIC-6 surface-mount package.

Feature Summary

• Built-in Schmitt trigger for noise immunity
• High common-mode transient immunity
• Logic output configuration for IPM driving

Applications

• Intelligent Power Module (IPM) gate drive isolation
• Industrial motor control systems
• Power supply feedback circuits

Procurement Notes

Verify the specific suffix '000E' matches the required RoHS compliance and tape-and-reel or tube packaging requirements. Confirm that the SOIC-6 footprint aligns with the target PCB design. Ensure the operating temperature range meets the environmental specifications of the end application. Cross-reference the datasheet revision date to guarantee parameter accuracy against current production units.

Selection Notes

Select this component when high-speed switching with inherent noise filtering is required for isolated gate drives. The integrated Schmitt trigger simplifies circuit design by reducing susceptibility to signal reflections and electromagnetic interference. Consider the 5000 Vrms isolation rating for safety compliance in high-voltage industrial environments. Evaluate the 6 ns transition times against the system's maximum switching frequency requirements.

Part Context

This part belongs to the ACPL-M483/P483/W483 family of fast-speed optocouplers. The W483 variant specifically denotes the logic output version optimized for inverting applications in power electronics. It shares the core AlGaAs LED technology with other family members but differs in output stage configuration and packaging options tailored for different mounting styles.

Replacement Considerations

Direct substitutes within the same family include ACPL-M483 and ACPL-P483, though pinout and output type may vary. Verify functional equivalence regarding propagation delay and isolation voltage before substitution. Check manufacturer documentation for any obsolescence notices or recommended upgrades.
