The TD62107PG is a high-voltage, high-current Darlington transistor array manufactured by Toshiba Semiconductor and Storage. It is designed for driving inductive loads such as relays, solenoids, and lamps directly from logic circuits. This device integrates seven NPN Darlington transistor pairs, each capable of sinking up to 500mA. The TD62107PG offers a convenient and efficient solution for interfacing low-power logic signals to high-power loads. The key difference between this and other parts in the TD6210x series is the input logic and internal configuration.

Additional Details

The TD62107PG features input clamp diodes that provide protection against inductive kickback when driving inductive loads. These diodes effectively suppress voltage spikes generated when the load is switched off, preventing damage to the transistors. The device operates over a wide temperature range, making it suitable for various industrial and automotive applications. The DIP-16 package allows for easy through-hole mounting. The collector-emitter saturation voltage is typically 1.6V at an output current of 350mA. The input current is typically 500μA. The device also offers high current transfer ratio. The input structure is designed for specific logic levels and noise immunity requirements, consult the datasheet for precise values. The 'G' likely indicates a green or lead-free version.
