Procurement Notes

Verify the specific suffix designation when ordering, as manufacturing changes may occur. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to integration. Check for end-of-life notices or obsolescence warnings, as availability may be limited. Ensure that the TO-18-3 pinout matches the target PCB footprint design requirements.

Selection Notes

Select this component for designs requiring a robust NPN transistor in a metal can package capable of withstanding high junction temperatures. Compare the 32 V voltage ratings and 100 mA current limits against circuit demands. Consider the 340 mW power dissipation capability relative to thermal management strategies. Evaluate the 150 MHz bandwidth against signal frequency requirements to ensure adequate performance margins.
