Description and Introduction

NPN SILICON PLANAR MEDIUM POWER HIGH VOLTAGE TRANSISTOR The ZTX457 is a high-voltage NPN bipolar junction transistor (BJT) manufactured by ZETEX (now part of Diodes Incorporated). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Collector-Emitter Voltage (VCE):** 400V  
- **Collector-Base Voltage (VCB):** 400V  
- **Emitter-Base Voltage (VEB):** 5V  
- **Collector Current (IC):** 500mA (continuous)  
- **Power Dissipation (Ptot):** 1W (at 25°C)  
- **DC Current Gain (hFE):** 40 to 320 (at IC = 10mA, VCE = 10V)  
- **Transition Frequency (fT):** 50MHz (typical)  
- **Operating Temperature Range:** -55°C to +150°C  
- **Package Type:** TO-92 (through-hole)  

### **Descriptions and Features:**  
- Designed for high-voltage switching and amplification applications.  
- Suitable for use in power supplies, inverters, and other high-voltage circuits.  
- Low saturation voltage for improved efficiency.  
- High current gain (hFE) range for flexibility in circuit design.  
- Robust construction for reliable performance in demanding environments.  

For exact performance characteristics, refer to the official datasheet from Diodes Incorporated (formerly ZETEX).
