MBR30L45CTG

Diode Arrays Overview

The MBR30L45CTG is a dual Schottky barrier rectifier manufactured by onsemi, designed for high-efficiency power conversion applications. It features a common cathode configuration with two independent anodes within a single TO-220-3 package. The device utilizes silicon technology to deliver a repetitive reverse voltage of 45 V and a total average forward current of 30 A, providing 15 A per diode leg. Key electrical parameters include a maximum forward voltage of 830 mV at the rated current and a peak non-repetitive forward surge current capability of 150 A. The component supports a junction temperature range from -65 °C to +175 °C, ensuring reliable operation in demanding thermal environments.

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and packaging variations. Ensure that the procurement channel provides original manufacturer documentation to validate RoHS compliance and lead-free status. Cross-reference the part number with official obsolescence notices to prevent supply chain disruptions during production.

Diode Arrays Selection Notes

Select this component when designing circuits that require a 45 V reverse voltage rating and a total continuous current of 30 A in a through-hole package. The low forward voltage drop makes it suitable for applications prioritizing thermal efficiency over higher voltage blocking capabilities. Compare the thermal resistance characteristics of the TO-220-3 package against the expected ambient temperature and heat sinking strategy to ensure the junction temperature remains within the specified operational limits.

Diode Arrays Part Context

This device belongs to the MBR30L series of Schottky rectifiers from onsemi, which are engineered for general-purpose power rectification. The series offers a balance of high current handling and low forward voltage drop, making it a standard choice for medium-power applications. It shares functional similarities with other dual Schottky devices but is distinguished by its specific 45 V rating and 30 A total current capacity in the TO-220-3 form factor.

Diode Arrays Replacement Considerations

Direct substitutes may include the MBR30H45CTG or MBR3045CTG, provided they meet the same electrical specifications and package requirements. Verify that any alternative component maintains the same dual common cathode configuration and thermal performance characteristics to ensure circuit compatibility.
