Allegro Darlington STD01N/P and STD02N/P: Audio-amplifier transistors feature enhanced thermal stability

Aiming at audio amplifiers in home and professional markets, the Darlington transistor series features a high SOA (safe-operating area). The STD01N/P and STD02N/P transistors provide a built-in thermal compensation diode on the same die, eliminating a delay for thermal-compensation operation and the delay between thermal sensing at the heat source and response at the compensation area. The devices achieve higher power levels by using decreased thermal resistance, making them suitable for applications requiring enhanced thermal stability. Available in a TO-3P package, the STD01N/P and STD02N/P cost $1.50 and $1.70 (1000), respectively.
