# Introduction to the MJE15035G Product Series

## 1. Overview
The MJE15035G product series is a line of high - performance bipolar junction transistors (BJTs) that play a crucial role in a wide range of electronic applications. These transistors are designed to meet the demanding requirements of modern electronic circuits, offering reliable and efficient performance.

## 2. Key Features

### Electrical Characteristics
- **High Voltage Capability**: The MJE15035G transistors are capable of handling relatively high voltages. This makes them suitable for applications where high - voltage switching or amplification is required. For example, in power supply circuits, they can withstand the high - voltage spikes and fluctuations, ensuring stable operation of the overall system.
- **Low Collector - Emitter Saturation Voltage**: They exhibit a low collector - emitter saturation voltage (VCE(sat)). This characteristic is beneficial as it reduces power dissipation in the transistor when it is in the saturated state. Lower power dissipation means less heat generation, which in turn improves the reliability and efficiency of the circuit. In audio amplifier circuits, a low VCE(sat) can lead to better audio quality by minimizing distortion.
- **High Current Gain**: These transistors have a high current gain (hFE). A high current gain allows for efficient signal amplification. In small - signal amplifier circuits, a high hFE enables the transistor to amplify weak input signals to a usable level with minimal additional power requirements.

### Package and Thermal Performance
- **TO - 220 Package**: The MJE15035G is typically available in the TO - 220 package. This package is well - known for its excellent thermal dissipation properties. The large surface area of the TO - 220 package allows heat to be transferred away from the transistor more effectively. This is essential for high - power applications where excessive heat can degrade the performance and lifespan of the transistor.
- **Thermal Resistance**: The transistors have a relatively low thermal resistance. This means that they can dissipate heat more efficiently, allowing them to operate at higher power levels without overheating. In power - hungry applications such as motor control circuits, the low thermal resistance ensures that the transistor can handle the continuous power dissipation without experiencing thermal runaway.

## 3. Applications

### Power Supplies
- **Switch - Mode Power Supplies (SMPS)**: In SMPS, the MJE15035G can be used as a switching transistor. Its high - voltage capability and fast switching speed make it suitable for converting high - voltage DC to low - voltage DC efficiently. The low VCE(sat) also helps in reducing power losses during the switching process, improving the overall efficiency of the power supply.
- **Linear Power Supplies**: In linear power supplies, these transistors can be used for voltage regulation. Their high current gain allows for precise control of the output voltage, ensuring a stable power supply for sensitive electronic components.

### Audio Amplifiers
- **Class - AB Amplifiers**: The MJE15035G can be employed in class - AB audio amplifiers. Its high current gain and low distortion characteristics make it ideal for amplifying audio signals. The low VCE(sat) helps in reducing crossover distortion, resulting in high - quality audio output.

### Motor Control
- **DC Motor Drives**: In DC motor control circuits, the MJE15035G can be used to control the speed and direction of the motor. Its ability to handle high currents and voltages makes it suitable for driving small to medium - sized DC motors. The fast switching speed of the transistor allows for precise control of the motor's operation.
