MBRD330RL

Single Diodes Overview

The onsemi MBRD330RL is a Schottky barrier rectifier rated for 3.0 amperes average forward current and a 30-volt maximum repetitive reverse voltage. It utilizes a DPAK surface-mount package (CASE 369C) designed for high-efficiency switching applications. The device features an extremely fast switching speed and low forward drop, supported by platinum barrier technology with avalanche guardrings. Maximum ratings include a peak repetitive forward current of 6 A at +125°C and a nonrepetitive peak surge current of 75 A. Thermal characteristics specify a junction-to-case resistance of 6 °C/W and a junction-to-ambient resistance of 80 °C/W.

Single Diodes Feature Summary

• Schottky barrier construction provides extremely fast switching capabilities and low forward voltage drop.
• Platinum barrier design incorporates avalanche guardrings to enhance reliability under transient conditions.
• Surface-mount DPAK package facilitates automated assembly and efficient thermal dissipation.

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration. The 'RL' suffix indicates tape and reel shipping containing 1800 units per reel. Confirm compliance requirements such as lead-free status if applicable to your manufacturing process. Ensure the selected variant matches the required mechanical mounting constraints and thermal management strategy for the target application environment.

Single Diodes Selection Notes

Select this component when a 30-volt blocking capability and 3-ampere continuous current rating are required in a compact surface-mount form factor. Evaluate the thermal resistance values against the expected ambient temperature and PCB copper area to ensure junction temperatures remain within the specified operating range. Consider the low forward voltage characteristic for efficiency optimization in low-voltage output stages.

Single Diodes Part Context

This device belongs to the MBRD3xx series of SWITCHMODE Power Rectifiers from onsemi. The series includes variants with different voltage ratings ranging from 20 to 60 volts, all sharing the same 3-ampere current rating and DPAK package outline. These devices are engineered specifically for high-frequency switching applications where low conduction losses and rapid recovery are critical performance factors.

Single Diodes Replacement Considerations

Compatible substitutes within the same family include MBRD320, MBRD340, MBRD350, and MBRD360. Verify that the alternative part's voltage rating meets or exceeds the circuit's maximum reverse voltage requirements. Ensure the replacement maintains the same DPAK footprint and pinout configuration to guarantee mechanical compatibility without PCB redesign.
