Description and Introduction

PNP SILICON PLANAR MEDIUM POWER HIGH VOLTAGE TRANSISTORS The ZTX557 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):** 60V  
- **Collector-Base Voltage (VCB):** 80V  
- **Emitter-Base Voltage (VEB):** 5V  
- **Continuous Collector Current (IC):** 1A  
- **Total Power Dissipation (Ptot):** 1W  
- **DC Current Gain (hFE):** 100 (minimum) at IC = 100mA  
- **Transition Frequency (fT):** 100MHz (typical)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Description:**  
The ZTX557 is designed for high-speed switching and amplification applications. It offers high current gain and low saturation voltage, making it suitable for use in power management, signal amplification, and switching circuits.  

### **Features:**  
- High current gain (hFE)  
- Low saturation voltage  
- High transition frequency for fast switching  
- Suitable for medium-power applications  
- Robust construction for reliable performance  

For exact performance characteristics, always refer to the official datasheet.
