E13003 Bipolar BJT Transistor NPN 400V 1.5A 4MHz TO-126

E13003 Bipolar BJT Transistor NPN 400V 1.5A 4MHz TO-126

The E13003 is a bipolar junction transistor (BJT) of the NPN type, functioning as a fundamental solid-state switch and amplifier for electronic circuits. Its core operation relies on using a small current applied to its base terminal to control a much larger current flow between its collector and emitter. Housed in a robust TO-126 package, this transistor is designed to handle substantial power levels, with the package itself acting as a crucial interface for dissipating generated heat to an external heatsink, thereby ensuring stable and reliable operation under load.

This device is engineered for medium-to-high voltage applications, characterized by a collector-to-emitter voltage rating of 400 volts. This high voltage capability makes it suitable for circuits operating directly from rectified mains electricity. It can support a continuous collector current of up to 1.5 amperes, allowing it to drive significant loads. The transition frequency of 4MHz indicates its operational speed limit, defining it as a component best suited for power switching and low-frequency amplification rather than for high-speed radio frequency applications.

In practice, the E13003 is often deployed in linear power supplies and offline switching power supplies, where it is repeatedly cycled between its fully on (saturation) and fully off (cut-off) states. Its ability to withstand high voltages and currents makes it a common choice for the power regulation and conversion stages of various electronic equipment. When in use, careful attention must be paid to its base drive current and operating temperature to ensure it remains within its safe operating area, preventing thermal runaway and ensuring long-term durability.
