The 2SD965 is a specific part number for a silicon NPN bipolar junction transistor (BJT). NPN transistors like the 2SD965 are commonly used in electronic circuits for amplification and switching applications. The 2SD prefix typically indicates a series of transistors, and the 965 part of the designation provides specific details about this particular transistor's characteristics.
Here are some key characteristics and specifications of the 2SD965 transistor:
Type: 2SD965 is an NPN bipolar transistor.
Package: It typically comes in a through-hole package, such as the TO-126, TO-220, or TO-92 package, which are commonly used for medium- to high-power transistors.
Polarity: As an NPN transistor, the current flows from the collector to the base and then to the emitter when it is in the active state.
Voltage and Current Ratings: The specific voltage and current ratings can vary depending on the specific manufacturer and part specifications. Typical voltage ratings for the 2SD965 might include a collector-emitter voltage (Vce) of around 60 to 80 volts, and a collector current (Ic) rating of several amperes (A).
Gain (hFE): The current gain or hFE (beta) of the 2SD965 transistor typically falls in the range of 60 to 240, depending on the specific part and manufacturer.
Applications: 2SD965 transistors are widely used in applications where NPN transistor amplification or switching is required. Common applications include signal amplification, small-signal switching, voltage regulation, and as a building block in analog and power electronics circuits.
Pinout: The pinout of the 2SD965 transistor includes three leads: collector, base, and emitter. The orientation of these pins is standardized in the TO-126, TO-220, or TO-92 package.
