Description and Introduction

8CH HIGH-VOLTAGE SOURCE DRIVER The TD62783 is a high-voltage, high-current Darlington transistor array manufactured by Toshiba. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Configuration:** 8-channel Darlington sink driver  
- **Output Voltage (Max):** 50V  
- **Output Current (Per Channel):** 500mA (Max)  
- **Input Voltage (Logic High):** 2.0V (Min)  
- **Input Current:** 2.5mA (Typical)  
- **Power Dissipation:** 1.25W (Per Channel)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** DIP-18, SOP-18  

### **Descriptions:**  
- Designed for interfacing between low-level logic and high-voltage/high-current devices.  
- Each channel includes a Darlington pair with a common-cathode clamp diode for inductive load protection.  
- Suitable for driving relays, solenoids, lamps, and LEDs.  

### **Features:**  
- **Built-in Clamp Diodes:** For inductive load protection.  
- **High-Voltage/High-Current Output:** Capable of driving loads up to 50V and 500mA.  
- **TTL/CMOS Compatible Inputs:** Works with 5V logic levels.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.  
- **Open-Collector Outputs:** Allows flexible load connections.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics, refer to Toshiba's official documentation.

Application Scenarios & Design Considerations

8CH HIGH-VOLTAGE SOURCE DRIVER

Alternative Part Number

  • ULN2803A --: Eight-channel Darlington sink driver with similar 50V/500mA ratings, widely used as a direct functional replacement for TD62783 in relay and lamp driving.
  • ULN2803APG --: Same manufacturer's Darlington transistor array with comparable output current and voltage, pin-compatible with the TD62783 series.
  • MC1413BDG --: Seven-channel high-voltage Darlington array offering equivalent sink-driver functionality and similar electrical characteristics.
  • ULQ2003A --: High-voltage Darlington transistor array rated 50V/500mA per channel, suitable for inductive load driving as an alternative to the TD62783.
