Bipolar Transistor Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and qualification level. Ensure the component matches the required military standard compliance before integration. Confirm lead times and availability directly with authorized distributors as supply levels fluctuate. Validate that the received part number corresponds exactly to the design specifications.

Bipolar Transistor Arrays Selection Notes

Select this component when a dual NPN transistor with high current gain and wide temperature tolerance is required. Consider the TO-78 surface mount package for board space constraints. Evaluate the 30 mA collector current limit against load requirements. Verify that the 60 V collector-emitter voltage rating exceeds the maximum circuit voltage.

Bipolar Transistor Arrays Part Context

This device belongs to the 2N2919/2920 family of dual NPN transistors manufactured by Microchip Technology. It shares structural similarities with the through-hole 2N2920 variant but utilizes a surface mount TO-78 package. The 'U' suffix denotes the specific surface mount configuration, while the '/TR' indicates tape and reel packaging for automated assembly processes.

Bipolar Transistor Arrays Replacement Considerations

Direct replacements must match the dual NPN configuration, TO-78 SMD package, and MIL-PRF-19500/355 qualification. Verify pinout compatibility and electrical parameters such as VCEO and hFE ranges. Cross-reference with other manufacturers offering equivalent military-grade dual transistors if available.
