The MJE13007R is a high-voltage, high-speed switching NPN bipolar transistor manufactured by ON Semiconductor (formerly Fairchild). It's designed for use in off-line power converters, power supplies, and electronic lighting ballasts where efficiency and reliability are crucial. The device features a robust design capable of withstanding high-voltage stress and exhibits fast switching characteristics to minimize power losses. It's typically packaged in a TO-220 configuration for efficient heat dissipation.

Applications:

• Off-line power converters (AC-DC)
• Switch-mode power supplies (SMPS)
• Electronic lighting ballasts (CFL, LED drivers)
• High-voltage inverters
• Auxiliary power supplies

Features:

• High Collector-Emitter Breakdown Voltage (VCEO): Provides a large safety margin in high-voltage applications.
• Fast Switching Speed: Reduces switching losses and improves overall efficiency.
• Low Saturation Voltage (VCE(sat)): Minimizes conduction losses and enhances efficiency.
• TO-220 Package: Allows for easy mounting and efficient heat removal.
• RoHS Compliant: Lead Free Finish/RoHS Compliant for environmental consciousness.

Benefits:

• Increased Efficiency: Fast switching and low saturation voltage contribute to higher power conversion efficiency.
• Enhanced Reliability: High breakdown voltage provides robustness against voltage transients.
• Reduced System Size: High switching frequency allows for the use of smaller passive components.
• Improved Thermal Performance: TO-220 package facilitates efficient heat sinking.
