MBR15200CT MBR15200CT Schottky Diode

MBR15200CT is a high-performance Schottky barrier rectifier manufactured by LGE, a reputable name in semiconductor solutions. This component is specifically designed for applications requiring very low forward voltage drop and fast switching, making it an ideal choice for power supplies, inverters, and freewheeling diodes. As a Schottky diode, it utilizes a metal-semiconductor junction, which eliminates the minority carrier storage time found in conventional PN junction diodes, thereby enabling much faster switching speeds and lower power losses. The MBR15200CT is housed in a robust TO-220AB package, ensuring efficient heat dissipation and ease of integration into various circuit designs, catering to the demands of modern power electronics with its superior efficiency and reliability.

Key Specifications

This section details the critical electrical parameters of the MBR15200CT, providing context for their importance in circuit design:

VFM V (Forward Voltage Maximum): 0.95V
The maximum forward voltage drop at a specified current is 0.95V. A lower VFM is crucial for minimizing power dissipation in the diode, which directly translates to higher efficiency in power conversion circuits and reduced heat generation. This attribute makes the MBR15200CT suitable for energy-efficient designs.

IFSM A (Non-Repetitive Peak Forward Surge Current): 150A
This value indicates the maximum current the diode can withstand for a very short duration, typically during power-up or transient events. A high IFSM of 150A provides excellent robustness against surge currents, enhancing the reliability and longevity of the circuit by preventing damage during unexpected current spikes.

I(AV) A (Average Forward Current): 15A
The average forward current rating of 15A signifies the maximum continuous current the diode can safely conduct under specified thermal conditions. This substantial current handling capability makes the MBR15200CT suitable for medium to high-power applications where continuous current flow is required.

Package / Case: TO-220AB
The TO-220AB package is a widely recognized industry standard for power semiconductors. Its design facilitates easy mounting to a heatsink, which is essential for dissipating the heat generated during operation, especially at higher currents. This package ensures thermal stability and simplifies assembly processes.

VRRM (I=IRM) V (Peak Repetitive Reverse Voltage): 200V
The maximum repetitive peak reverse voltage of 200V indicates the highest voltage the diode can withstand in the reverse direction without breaking down. This rating is critical for ensuring the diode’s integrity in circuits where significant reverse voltages are present, providing a safety margin for various power supply designs.

IRM TA=25℃ mA (Reverse Current Maximum at 25°C): 0.1mA
The maximum reverse current at 25°C is 0.1mA. A low reverse current is desirable as it indicates minimal leakage when the diode is reverse-biased, contributing to higher efficiency and reduced power loss, particularly in standby or low-power modes.

Device / IC Type: Schottky Diode
This confirms the device’s fundamental operating principle. Schottky diodes are characterized by their fast switching speed and low forward voltage drop, making them superior to standard PN junction diodes in high-frequency and power-efficient applications.
