MBR40L45CTG

Diode Arrays Overview

The MBR40L45CTG is a dual Schottky barrier rectifier manufactured by onsemi, designed for high-efficiency power conversion applications. It features a common cathode configuration housed in a TO-220AB package with three leads. The device utilizes silicon technology to deliver a repetitive peak reverse voltage of 45 V and an average forward rectified current of 20 A. Key electrical parameters include a maximum forward voltage of 630 mV at 10 A per leg, a non-repetitive peak forward surge current of 150 A, and a maximum reverse leakage current of 1.2 mA. It operates within a junction temperature range of -65 °C to +175 °C.

Diode Arrays Feature Summary

• Dual Schottky barrier rectifier configuration with common cathode connection
• Guard-ring structure provides enhanced stress protection for reliability
• Low forward voltage characteristic minimizes conduction losses
• High thermal stability supports operation up to 175 °C junction temperature

Diode Arrays Applications

• DC-to-DC converter output rectification
• Free-wheeling diodes in synchronous rectifier circuits
• Power management systems requiring low loss rectification

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and packaging type. Ensure the component meets RoHS directives if required by your assembly process. Cross-reference the part number with authorized distributors to confirm availability and authenticity. Check for any recent product change notices that may affect mechanical dimensions or electrical specifications before finalizing procurement.

Diode Arrays Selection Notes

Select this component when designing circuits that require a 45 V blocking capability with a 20 A total current rating in a through-hole package. The dual common cathode arrangement is suitable for full-wave rectification or push-pull topologies. Consider the thermal resistance of the TO-220AB package and ensure adequate heatsinking to maintain junction temperatures within the specified 175 °C limit under continuous load conditions.

Diode Arrays Part Context

This device belongs to the MBR40L series of dual Schottky rectifiers from onsemi. It shares functional similarities with other parts in the family but is distinguished by its specific 45 V voltage rating and 20 A current handling capacity. The series is engineered for general-purpose switching power supplies where efficiency and speed are critical performance factors.

Diode Arrays Replacement Considerations

Direct substitutes include the MBR40L45WTG, which offers identical electrical characteristics in a different package variant. Verify pinout alignment and thermal performance when replacing with equivalent parts from other manufacturers.
