Download free 2n2222 pinout10/11/2023 ![]() Emitter-base Voltage VEBO (I C = 0) 5 V.Collector-emitter VCEO Voltage (I B = 0) 30 V.Collector-base Voltage VCBO (I E = 0) 60 V.The maximum technical specifications of 2N2222 (at TA < +25oC): The datasheet states that the device is designed to operate at high switching speeds and provide effective amplification over a wide frequency range. They are true at ambient temperature (TA) of no more than +25oC. Let’s take a closer look at the 2N2222 transistor, its specifications and features. You should note that the “K” pin is physically connected to the metal case. The pin assignment is as follows (clockwise from the small protrusion): We can minimize energy dissipation by making a rapid transition between the off and on states.The pinout of the 2N2222 in the TO-18 is shown in the figure below. This causes heating problems and reduces efficiency. ![]() Significant energy dissipates by MOSFET whenever the gate is not fully on or fully off. This shorts the power supply and will likely damage the MOSFETS. Shoot-through means that the two MOSFETS are on at the same time. So it must be kept in consideration Shoot through The following things fall under consideration while creating H-Bridge motor driver circuit: Electrical Noiseĭuring the working of the H-Bridge motor driver circuit, the motor can make noises and can damage the MOSFETS. When terminal B is grounded and C is connected to +Vcc, transistors Q3 and Q2 will be on and current passes through the motor from right to right causing the motor to revolve in the opposite direction. When terminal D is grounded and A is connected to +Vcc, transistors Q1 and Q4 will be on and current passes through the motor from left to right. The Working of this circuit is very easy to understand. Thus it protects the corresponding MOSFET from damage. The diodes D1 to D4 provide a safer path for the back EMF from the motor. ![]() The MOSFETS are used as switches and are activated in diagonal pairs. In the circuit, we see that the 4 MOSFET surrounding the motor form an “H” shape. ![]()
