Overview
The ACPL-M46T-000E is a logic output optocoupler from Broadcom Limited, designed for intelligent power module interfaces. It features a single channel with an open collector Schottky clamped output. 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 minimum isolation voltage of 4000 Vrms, a DC current transfer ratio of 90%, and a maximum propagation delay of 550 ns. It operates within a temperature range of -40°C to +125°C and is housed in a 5-SOIC package.
Feature Summary
- High common-mode transient immunity of 15 kV/µs for reliable signal transmission in noisy environments
- Schottky clamped open collector output structure for fast switching performance
- Wide operating temperature range suitable for demanding industrial applications
Applications
- Intelligent Power Module (IPM) gate drive interface
- Industrial motor control systems
- Inverter and converter circuits
Procurement Notes
Verify the specific suffix '000E' against the manufacturer's latest datasheet to confirm pinout and functional specifications. Ensure that the required isolation voltage and CMTI ratings align with the target application's safety standards. Cross-reference the RoHS compliance status and packaging details directly with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when high-speed digital isolation is required between low-voltage control logic and high-voltage power stages. The 15 kV/µs CMTI rating makes it suitable for applications with rapid voltage transients. Consider the 5-SOIC package size for PCB layout constraints and verify that the input forward current requirements match the driving circuit capabilities.
Part Context
This part belongs to Broadcom's ACPL-M46 series, which are specialized optocouplers engineered for IPM applications. The series is characterized by enhanced reliability and speed compared to standard optocouplers. The ACPL-M46T-000E specifically targets automotive and industrial power electronics where robust isolation and fast response times are critical for system stability.
