The JANS2N2920U is a dual small-signal NPN bipolar junction transistor (BJT) manufactured by Microchip Technology. It is housed in a TO-78-6 hermetic package designed for surface mount installation. The device supports an input voltage range up to 60V and delivers a continuous collector current of 30mA with a power dissipation rating of 350mW. It operates within a temperature range of -65°C to +200°C, featuring a reference voltage of 1.266V and a static current of 140uA. The component exhibits a line regulation of 0.03% and load regulation of 0.04%, ensuring stable performance in demanding environments.
Verify the specific ordering suffix against the manufacturer's datasheet to confirm radiation hardness levels and testing standards. Ensure compatibility with TO-78-6 footprints during PCB layout. Confirm moisture sensitivity classification prior to soldering processes to prevent package damage during assembly.
Select this component when radiation tolerance and high-temperature operation are critical requirements. The TO-78-6 package provides superior environmental sealing compared to standard plastic packages. Verify that the 30mA current limit and 350mW power dissipation meet the specific circuit demands before finalizing the design.
This part belongs to the 2N2920 series of dual small-signal transistors produced under military and space-grade specifications. It serves as a specialized variant designed for harsh environments where standard commercial components would fail due to radiation exposure or extreme thermal conditions.
