MJE350 PNP Power Transistor Datasheet

Introduction

The MJE350 is a high-voltage PNP power transistor designed for audio amplifier stages, power supply regulators, and high-voltage switching applications. Encased in a TO-225 package, it provides durability, efficient thermal management, and stability for medium-power electronic designs. The MJE350 is commonly used where high collector-emitter voltage handling and moderate current capability are required, making it suitable for both industrial and consumer electronics.

With a maximum collector-emitter voltage rating of -300V and a collector current of -0.5A, the MJE350 is ideal for circuits requiring reliable voltage endurance. Its frequency response and gain characteristics make it particularly useful in audio amplifier driver stages, push-pull configurations, and linear regulator designs. When paired with its NPN counterpart, the MJE340, it can be used in complementary designs, ensuring symmetry and performance in audio circuits.
