How do I choose a replacement transistor?

Choose a transistor with a similar power dissipation : It is necessary to ensure that the replacement transistor can handle the power that it will dissipate within the circuit. Choosing a replacement transistor with a similar can style will often mean that both transistors have a similar power dissipation.

What is D965 transistor?

2SD965 (D965) Silicon NPN epitaxial planar type. For low-frequency power amplification. For stroboscope.

Are all transistors the same?

All the transistors are not the same. Based on the structure, the transistors are classified as Bipolar Junction Transistor and Field Effect Transistor. The Bipolar Junction Transistors are further classified as PNP and NPN depending on the construction.

How do you find a transistor?

Connect the positive lead of the multimeter to the Base (B) of the transistor and connect the negative lead to the Emitter (E) of the transistor. If it is an NPN transistor then meter should show a voltage drop between 0.45V and 0.9V. If it is a PNP transistor, then it should display see “OL” (Over Limit).

What do the numbers on a transistor mean?

Its format for transistors is two letters followed by a serial number. The first letter represents the material. For instance, A means germanium and B means silicon. The second letter refers to transistor type. For instance, C means small signal and D means power.

What is D882 transistor?

The D882 is a general-purpose transistor that belongs to the NPN transistor family. It comes with collector current 5A and is mainly used for switching and amplification purpose. The amplification factor is 60-400. This factor indicates the amount of current this device can amplify.

Do all NPN transistors work the same?

At the most basic level all NPN type transistors do work in teh same manner. the same goes for all PNP transistors. At their most basic level the principles of operation are the same. A small control current adjusts teh flow of the larger current flow between the Emitter and the Collector.

How do you know if a transistor is open?

Connect the base terminal of the transistor to the terminal marked positive (usually coloured red) on the multimeter. Connect the terminal marked negative or common (usually coloured black) to the collector and measure the resistance. It should read open circuit (there should be a deflection for a PNP transistor).
