TIP111 is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists Central Semiconductor Corp. Its product description is TRANS NPN DARL 80V 2A TO-220-3. Review the specifications below when checking this part for your BOM.
The Central Semiconductor TIP111 is an NPN silicon Darlington power transistor housed in a TO-220AB package. It features a maximum collector-emitter voltage of 80V and a continuous collector current rating of 2A. The device includes a built-in base-emitter resistor and a flyback diode for circuit protection. It operates within a junction temperature range of -65°C to +150°C and has a maximum power dissipation capability of 50W.
Verify the specific ordering suffix (PBFREE or TIN/LEAD) required for your assembly process, as standard designation allows either plating type depending on availability. Confirm current stock status as this component may be subject to discontinuation notices; check for available inventory or special order options directly with the manufacturer.
Select this component when an NPN Darlington transistor with integrated protection is needed. Ensure the application voltage does not exceed 80V and current stays within 2A limits. Consider the thermal management requirements for the TO-220AB package if operating near maximum power dissipation.
This part belongs to the TIP11x series of Darlington transistors. It is functionally similar to the TIP110 but offers a lower voltage rating. The series is designed for general-purpose power switching and amplification tasks requiring high input impedance and substantial output current handling capabilities.
Official documentation lists the TIP112 as the suggested replacement for the TIP111.
