## Technical Overview: 2SC2383-R Transistor The **2SC2383-R** is a high-voltage NPN epitaxial silicon transistor. It is widely recognized for its use in color television circuits, specifically for horizontal deflection output and high-voltage switching applications. --- ### 1. Key Specifications The "R" suffix in the part number typically refers to the **hFE (DC Current Gain) rank**, indicating a specific range of gain for that batch. | Characteristic | Symbol | Value | Unit | | :--- | :--- | :--- | :--- | | **Type** | - | NPN | - | | **Collector-Base Voltage** | $V_{CBO}$ | 160 | V | | **Collector-Emitter Voltage** | $V_{CEO}$ | 160 | V | | **Emitter-Base Voltage** | $V_{EBO}$ | 6 | V | | **Collector Current (DC)** | $I_C$ | 1 | A | | **Collector Dissipation** | $P_C$ | 900 | mW | | **DC Current Gain (R-Rank)** | $h_{FE}$ | 60 to 120 | - | | **Transition Frequency** | $f_T$ | 100 (Typ) | MHz | --- ### 2. Physical Characteristics (Package) The 2SC2383-R usually comes in a **TO-92L** (also known as TO-92MOD) package. This is slightly taller than a standard TO-92, allowing for better heat dissipation and higher power handling. **Pinout Configuration (Front View):** 1. **Emitter (E)** 2. **Collector (C)** 3. **Base (B)** --- ### 3. Core Features * **High Voltage Handling:** Capable of sustaining $160V$, making it ideal for driving circuits that operate above standard logic levels. * **High Speed:** With a transition frequency ($f_T$) of 100MHz, it is suitable for high-frequency switching. * **Excellent Linearity:** Provides stable gain, which is crucial for signal amplification. * **Complementary Pair:** The **2SA1013** is the PNP complement to the 2SC2383, often used together in push-pull amplifier stages. --- ### 4. Common Applications 1. **TV/Monitor Circuits:** Specifically used in the Color Switching and Video Output stages. 2. **Audio Amplifiers:** Used in driver stages where high voltage swing is necessary. 3. **Power Supplies:** Acts as a high-voltage switch or a series pass transistor in voltage regulators. 4. **Signal Drivers:** Driving high-voltage relays or solenoids. --- ### 5. Equivalent/Replacement Parts If you cannot find a 2SC2383-R, the following transistors are common substitutes (ensure you check pinouts and voltage ratings): * **2SC2235** * **KSC2383** (Fairchild/ON Semi version) * **MJE340** (Different package, but handles high voltage)
