Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required plating configuration. The 'BK' designation indicates bulk packaging, while 'TR' indicates tape and reel. Confirm the 'PBFREE' suffix aligns with lead-free manufacturing requirements. Ensure compatibility with the intended mounting method before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a precise 27 V reference is required in an axial package. The ±5% tolerance suits general-purpose regulation tasks. Evaluate the thermal environment against the specified junction temperature limits. Consider the forward voltage drop during reverse recovery if used in switching circuits.
