Single Zener Diodes Procurement Notes

Verify the specific ordering suffix when purchasing. The 'G' suffix indicates a Pb-Free package, while 'RL' denotes tape and reel packaging. Confirm that the required quantity matches the standard shipping unit, which is typically 1000 units per box for bulk or 4000 units per tape and reel. Ensure the selected variant aligns with the intended manufacturing process regarding lead-free compliance requirements.

Single Zener Diodes Selection Notes

Select this component based on the precise 28 V nominal requirement and the need for tight ±5% voltage tolerance. Consider the 5 W power dissipation capability and the thermal resistance characteristics when designing heat management strategies. Verify that the operating temperature range meets the application's environmental demands and that the axial lead configuration fits the PCB layout constraints.
