Description and Introduction

Single-transistor array (common-emitter) The TD62503FNG is a high-voltage, high-current Darlington transistor array manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Toshiba  
- **Type:** Darlington Transistor Array  
- **Number of Channels:** 7 (7-channel)  
- **Output Configuration:** Open Collector  
- **Maximum Output Voltage (VCEO):** 50V  
- **Maximum Output Current (IO):** 500mA per channel  
- **Input Voltage (VIH):** 2.5V (min)  
- **Input Current (IIH):** 10μA (max)  
- **Power Dissipation (Pd):** 1.5W (total)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** DIP-16  

### **Descriptions:**  
- The TD62503FNG is a monolithic IC containing seven Darlington pairs with common emitters.  
- Each channel has an open-collector output capable of driving high-voltage and high-current loads.  
- It includes built-in suppression diodes for inductive load protection.  
- Designed for interfacing between low-level logic (e.g., TTL, CMOS) and high-power loads like relays, lamps, and motors.  

### **Features:**  
- **High-Voltage Outputs:** Up to 50V per channel.  
- **High-Current Drive:** 500mA per channel (sink capability).  
- **Integrated Clamp Diodes:** For back EMF protection.  
- **Wide Input Voltage Compatibility:** Works with TTL, CMOS, and other logic levels.  
- **Low Input Current Requirement:** Suitable for microcontroller interfacing.  
- **Compact DIP Package:** Easy to integrate into PCB designs.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Single-transistor array (common-emitter)

Alternative Part Number

  • ULN2003ADR --: Seven-channel Darlington sink driver in SOIC, functionally similar to the TD62503FNG transistor array and widely available.
  • MC1413BDR2G --: Seven-channel Darlington array with comparable output ratings, a common cross for Toshiba TD62 series drivers.
  • ULQ2003ATDRQ1 --: Automotive-qualified seven-channel Darlington driver offering similar sink current and logic-compatible inputs.
  • ULQ2003ADR --: High-voltage seven-channel Darlington array in SOIC-16, suitable when higher breakdown voltage is needed and pin-compatible with the original.
