Procurement Notes
Verify component status as obsolete before procurement planning. Confirm availability through authorized distributors or secondary markets. Check lead times carefully due to potential stock limitations. Ensure compatibility with existing design specifications if replacing active components. Validate authenticity through official Bourns channels.
Selection Notes
Select this component for high-current NPN switching requirements within the specified voltage limits. Consider the TO-220 package for adequate heat dissipation without additional heatsinking in low-duty cycles. Verify that the hFE minimum meets circuit biasing needs. Evaluate thermal management strategies given the 2W power rating and 150°C junction limit.
Part Context
This part belongs to Bourns' discrete semiconductor portfolio, specifically bipolar transistors. While Bourns is widely recognized for resistors, potentiometers, and sensors, this specific model represents their historical offering in power transistor solutions. The product line supports various industrial and consumer electronic designs requiring robust switching elements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult manufacturer cross-reference guides or technical support for equivalent NPN transistors with matching 100V/6A ratings and TO-220 packaging.
