Description and Introduction

DC-coupled vertical deflection output circuit The TDA8351AQ is a vertical deflection output amplifier manufactured by PHILIPS (now NXP Semiconductors). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Type:** Vertical deflection output amplifier  
- **Supply Voltage (Vs):** 10V to 35V  
- **Output Current (Io):** Up to 3A peak  
- **Power Dissipation (Ptot):** 12W (with heatsink)  
- **Package:** SIL-9 (Single In-Line with 9 pins)  
- **Operating Temperature Range:** -25°C to +150°C  

### **Descriptions:**  
- Designed for driving vertical deflection coils in CRT-based TVs and monitors.  
- Features a high-efficiency class G/H output stage.  
- Includes built-in protection circuits (thermal shutdown and short-circuit protection).  
- Requires minimal external components for operation.  

### **Features:**  
- High output current capability (3A peak).  
- Low power dissipation due to efficient switching operation.  
- Internal flyback generator for retrace supply.  
- Differential input for improved noise immunity.  
- Thermal protection to prevent overheating.  

The TDA8351AQ is optimized for use in 50Hz and 60Hz deflection systems.
