KS3302BU is listed in the Single Bipolar Transistors range at ChipApex. The manufacturer field lists onsemi. Its product description is TRANS NPN 40V 0.2A TO-92-3. Review the specifications below when checking this part for your BOM.
The KS3302BU is a single NPN bipolar junction transistor (BJT) manufactured by onsemi. It features a collector-emitter voltage rating of 40 V and a continuous collector current capacity of 200 mA. The device is housed in a TO-92-3 through-hole package, suitable for general-purpose switching and amplification applications. It operates within a standard commercial temperature range.
Verify the manufacturer origin carefully, as this part number originates from Fairchild Semiconductor prior to its acquisition by onsemi. Ensure the specific lot date code aligns with current supply chain requirements. Confirm that the TO-92-3 package variant matches the design footprint exactly. Check for any obsolescence notices or last-time buy notifications associated with legacy inventory sources.
Select this component when a low-cost, through-hole NPN transistor is required for moderate current switching tasks. The 40V rating provides sufficient headroom for low-voltage logic interfaces. Consider thermal dissipation limits in the TO-92 package if operating near the maximum current threshold. Verify compatibility with existing PCB layouts designed for standard axial leads.
This component belongs to the family of small-signal bipolar transistors used in analog and digital circuit designs. Historically produced by Fairchild Semiconductor, it remains available under the onsemi portfolio following corporate integration. These devices serve as fundamental building blocks for basic electronic functions in cost-sensitive consumer products.
