Motor Driver Circuit using a D880 Transistor An appropriate heat sink needs to use along with a transistor & operate the transistor always > -55 degree centigrade & < +150 degree centigrade. The maximum voltage from collector to emitter terminal is 60V thus do not drive any load above 48V. The maximum collector current (Cc) is 3A so does not drive any load above 2.4A. For that, it is recommended to use below 20% of its complete maximum ratings. How Long D880 Transistor is used Securely in a Circuit?īy using this D880 transistor, we can get stable performance within a circuit. So need to check before changing within the circuit. Here is the equivalent and replacement D880 transistors available but the pin configuration of these transistors are different.

Maximum storage and operating temperature must be from -55 to +150 CĮquivalent of D880 PNP transistor is 2SB834 whereas D880 equivalent NPN transistors are SC1826, NTE152 & BD241.

Voltage from emitter to base/VEB (Max) is 7V.

Voltage from collector to base/VCB (Max) is 60V.

Dissipation of collector/Pc (Max) is 30 Watts.

Voltage from collector to the emitter (VCE) is 60V.

Transition frequency/ fT (Max) is 3 MHz.

DC Current Gain/hFE (Min & Max) is 60 to 300.

The features and specifications of the D880 transistor include the following.

Pin3 (Emitter): The flow of current will drain out throughout this terminal and it is also connected to GND.

Pin2 (Collector): This terminal allows the flow of current and generally it is connected to GND.

Pin1 (Base): This terminal is used to control the transistor’s biasing by switch ON/OFF the transistor.

This transistor includes three terminals like E(Emitter), B (base), and C (collector) where each pin & its functionality is discussed below. The pin configuration of the D880 Transistor is shown below along with its symbol.
