Overview

The MMBD452_R1_00001 is a surface mount Schottky diode manufactured by Panjit International Inc. in an SOT-23 plastic case. It features a maximum reverse voltage of 30V and a total power dissipation of 200mW. The device exhibits extremely fast switching speed with a typical forward voltage of 0.36V at 1mA forward current. Electrical characteristics include a maximum reverse leakage current of 1µA at 30V, a maximum junction temperature range from -55°C to +150°C, and a maximum capacitance of 1.5pF at 15V reverse bias.

Feature Summary

• Extremely fast switching speed suitable for high-frequency applications
• Low forward voltage drop reducing conduction losses
• Low capacitance design minimizing signal interference
• Lead-free construction compliant with EU RoHS directives

Applications

• High-speed switching circuits
• RF detection applications
• Power supply rectification

Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as the R1 code indicates Tape and Reel packing on a 7-inch reel. Ensure compliance with environmental standards such as RoHS and Halogen-free requirements during procurement. Confirm that the component meets the specified thermal and electrical ratings for the intended operating environment before finalizing orders.

Selection Notes

Select this component when low forward voltage and minimal capacitance are critical for circuit performance. The SOT-23 package offers space-saving advantages for compact designs. Verify that the 30V reverse voltage rating aligns with the peak inverse voltage requirements of the application to ensure reliable operation under all expected conditions.

Part Context

This part belongs to the MMBD301/MMBD452 series of single surface mount Schottky diodes. It shares identical electrical specifications with the MMBD301 variant but is distinguished by its specific ordering suffixes which define the packaging type and environmental compliance status. The series is designed for general-purpose high-speed switching and rectification tasks.

Replacement Considerations

The MMBD301 serves as a direct functional equivalent within the same series. Verify that any substitute maintains the SOT-23 footprint and matches the 30V reverse voltage and 200mW power dissipation limits to ensure compatibility without redesigning the PCB layout.
