Single Zener Diodes Procurement Notes
Verify the specific suffix matches the required voltage tolerance and impedance parameters. Confirm RoHS compliance status for the manufacturing date code. Ensure the 0603 footprint aligns with the recommended pad layout provided in the datasheet. Check for any design-in restrictions as this series may not be recommended for new designs.
Single Zener Diodes Selection Notes
Select based on the required 39 V reference point and the 0603 package constraint. Consider the thermal derating curve for power dissipation limits above 25 °C. Evaluate the dynamic impedance and reverse leakage current against circuit sensitivity requirements. Verify compatibility with the intended operating temperature range of -55 °C to +125 °C.
Single Zener Diodes Part Context
This component belongs to the CD0603/1005-Z Surface Mount Zener Diode Series by Bourns Inc.
