STD01N and STD01P: Darlington Transistors for Audio Amplifiers

The STD01N and STD01P are enhanced Darlington transistors with built-in drivers and temperature compensation diode. Manufactured using the unique Sanken thin-wafer production technology, these devices achieve higher power levels through decreased thermal resistance, and can withstand higher voltages than similar devices on the market.

The temperature compensation diode is integrated on the same chip as the power transistors. By this design, the STD01N and STD01P eliminate delays that would otherwise be induced between thermal sensing at the heat source, and the operation of the compensation circuitry. Thus, these transistors are ideal for applications where enhanced thermal stability is required.

This device is provided in a 5-pin TO-3P plastic package with pin 4 removed. Contact Allegro for application support and additional information on device performance.
