Description and Introduction

NPN SILICON PLANAR MEDIUM POWER HIGH CURRENT TRANSISTOR The ZTX851 is a high-performance NPN bipolar junction transistor (BJT) manufactured by ZETEX (now part of Diodes Incorporated). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Type:** NPN Bipolar Transistor  
- **Collector-Emitter Voltage (VCE):** 45V  
- **Collector-Base Voltage (VCB):** 45V  
- **Emitter-Base Voltage (VEB):** 5V  
- **Continuous Collector Current (IC):** 500mA  
- **Total Power Dissipation (Ptot):** 1W  
- **DC Current Gain (hFE):** 100–400 (typically 200 at IC = 10mA)  
- **Transition Frequency (fT):** 175MHz  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package:** TO-92  

### **Descriptions and Features:**
- Designed for general-purpose amplification and switching applications.  
- High current gain (hFE) with low saturation voltage.  
- Suitable for low-noise and high-speed applications.  
- Robust construction for reliable performance in various circuits.  
- Commonly used in audio amplifiers, signal processing, and driver stages.  

The ZTX851 is a versatile transistor with a balance of speed, current handling, and voltage tolerance.
