Description and Introduction

8CH SINGLE DRIVER : COMMON EMITTER The TD62597AFN is a high-voltage, high-current Darlington transistor array manufactured by Toshiba. Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Type:** Monolithic Darlington Transistor Array  
- **Configuration:** 8-channel (8 Darlington pairs)  
- **Output Voltage (VCE):** 50V (max)  
- **Output Current (IC per channel):** 500mA (max)  
- **Input Voltage (VIN):** 5V TTL/CMOS compatible  
- **Input Current (IIN):** 2.5mA (max per channel)  
- **Power Dissipation (PD):** 1.5W (total)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DIP-18 (Plastic)  

### **Descriptions:**
- The TD62597AFN integrates eight Darlington transistor pairs with common emitters, designed for interfacing low-voltage logic circuits (TTL/CMOS) with high-voltage/high-current loads.  
- Each channel includes a suppression diode for inductive load protection.  
- Suitable for driving relays, solenoids, lamps, and other high-power devices.  

### **Features:**
- **High-Voltage Output:** Supports up to 50V per channel.  
- **High-Current Capability:** 500mA per channel (sink current).  
- **Built-in Clamp Diodes:** Protects against back EMF from inductive loads.  
- **TTL/CMOS-Compatible Inputs:** Works with 5V logic levels.  
- **Wide Operating Temperature Range:** Suitable for industrial applications.  
- **Monolithic IC Design:** Ensures reliability and compact integration.

Application Scenarios & Design Considerations

8CH SINGLE DRIVER : COMMON EMITTER

Alternative Part Number

  • ULN2003ADR --: Seven-channel Darlington sink driver in SOIC-16, functionally similar to the TD62597AFN array and widely available as a drop-in style replacement.
  • MC1413BDR2G --: Seven-channel Darlington transistor array with high-voltage/high-current outputs, a common industry-standard substitute for Toshiba TD62-series sink drivers.
  • ULQ2003ADR --: Automotive-grade seven-channel Darlington array with comparable output ratings and pinout, suitable when higher ruggedness is needed.
