Part points
-
The 2SD1773, manufactured by Panasonic Electronic Components, is a Bipolar Junction Transistor (BJT) in the NPN configuration. It belongs to the Darlington type, designed for high current gain (h_{fe})), high voltage gain (A_v), and low output impedance. Key specifications of 2SD1773 include a maximum collector-emitter voltage (V_{CE}) of 120V, a max collector current (I_C) of 8A, and a high-frequency cutoff (f_T) around 20MHz. The transistor is available in a TO-220 package with a full pack for secure handling. This device finds applications where high current gain, low output impedance, or high voltage gain are required. However, since the feature and application sections specify 'None', this suggests that the 2SD1773 has more specialized uses or is designed for specific circuits rather than being a general-purpose transistor.
-
Equivalent
The equivalent product for 2SD1773, a Panasonic NPN Darlington transistor, would be other high-power NPN Darlington transistors from brands like Fairchild or ON Semiconductor, such as 2N3904 or BC847C. -
Features
The 2SD1773, also known as a Panasonic Darlington NPN transistor, features several key attributes:
High Current Capability: The transistor can handle an 8 ampere current at up to 120 volts.
Wide Frequency Response: With a frequency range of 20 MHz, it's suitable for high-speed applications.
High Gain and Stability: As a Darlington transistor, it offers significantly enhanced gain compared to a single NPN transistor.
Through-Hole TO-220F Package: This package allows easy mounting in electronic circuits using standard hole patterns. Overall, the 2SD1773 transistor is designed for high current, high speed, and stability in demanding electronic applications. -
Pinout
The 2SD1773, a Panasonic bipolar junction transistor (BJT), belongs to the Darlington pair family. As for the pin count and functions: - TO-220 package has three pins:
Collector (C): High current output.
Emitter (E): Low voltage input.
Base (B): Controls the collector current. Please note that Darlington configurations often have only two terminals (emitter and collector), simplifying the pin count for these specific applications. -
Manufacturer
The 2SD1773 is manufactured by Panasonic Electronic Components. Panasonic is a Japanese multinational electronics corporation, known for its wide range of consumer electronics, home appliances, and industrial products. -
Application Field
The 2SD1773, a Panasonic bipolar transistor, finds applications in power amplifiers, switching circuits, and motor control in electronic devices. -
