STD03N
STD03N is Darlington Transistors manufactured by Allegro MicroSystems.
STD03N and STD03P Darlington Transistors for Audio Amplifiers
Features and Benefits
- Built-in temperature pensation diodes
- High power (160 W) handling in a small package (TO-3P), for minimized heat sink requirements
- Built-in drivers and temperature pensation diodes, reducing external ponent count and simplifying circuit design
- NPN and PNP versions
- Emitter terminals placed symmetrically, pin 5 on NPN and pin 1 on PNP models, allowing adjacent placement on PCB to minimize trace length and output skew when used in pairs
- Approved by major manufacturers
Description
The STD03N and STD03P are enhanced Darlington transistors with built-in drivers and temperature pensation 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 pensation diode is integrated on the same chip as the power transistors. By this design, the STD03N and STD03P eliminate delays that would otherwise be induced between thermal sensing at the heat source, and the operation of the pensation 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.
