Single Bipolar Transistors Procurement Notes

Verify the specific manufacturer source, as the 2N697 designation has been produced by multiple vendors including New Jersey Semi-Conductor Products and Microsemi. Confirm that the 2N697S suffix corresponds to the exact pinout and mechanical dimensions required for your PCB footprint. Ensure RoHS compliance status matches project requirements, as legacy hermetic packages may have different regulatory classifications than modern equivalents.

Single Bipolar Transistors Selection Notes

Select this component when hermetic sealing is mandatory for radiation or harsh environment resistance. The TO-39 form factor requires through-hole mounting with specific hole spacing. Compare the 40V collector-emitter rating against peak circuit voltages to ensure adequate margin. Consider the thermal resistance of the metal case for heat dissipation needs in amplifier configurations.

Single Bipolar Transistors Part Context

The 2N697 series belongs to a class of medium power NPN silicon transistors historically used in military and aerospace electronics. The 'S' suffix typically denotes a specific variant or manufacturer-specific revision within the broader 2N697 family. These devices represent legacy technology still maintained for compatibility in existing defense and industrial infrastructure designs.
