Description
B31N20D is 200V, 31A, SMPS MOSFET.
A SMPS (Switched-Mode Power Supply) MOSFET refers to a metal-oxide-semiconductor field-effect transistor designed for use in switched-mode power supply applications. Let’s break down the specifications:
- Voltage Rating: The MOSFET has a maximum voltage rating of 200 volts (V). This means it can handle a maximum voltage of 200V in its operating conditions without the risk of damage.
- Current Rating: The MOSFET has a maximum current rating of 31 amperes (A). This specifies the maximum continuous current that can flow through the transistor without exceeding its current handling capacity.
SMPS MOSFETs are specifically designed to handle high voltages and high currents typically encountered in switched-mode power supply circuits. Switched-mode power supplies are widely used in various applications, including computers, telecommunications equipment, consumer electronics, and industrial systems.
Benefits:
1. Low Gate-to-Drain Charge to Reduce Switching Losses
2. Fully Characterized Capacitance Including Effective COSS to Simplify Design
3. Fully Characterized Avalanche Voltage and Current
