Procurement Notes
Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the presence of the cathode band and full part number marking on the DO-41 glass case. Ensure the ordering suffix matches the required plating configuration, as specified in Central Semiconductor's ordering guidelines.
Selection Notes
Select this component when a 5.1V reference or regulator is required in a standard axial leaded package. Verify that the 1.0W power dissipation rating and the specific impedance characteristics meet the circuit requirements. Consider the operating temperature range and the hermetic nature of the glass package for the intended environment.
Part Context
This device belongs to the 1N4728A through 1N4764A series of 1-watt silicon Zener diodes manufactured by Central Semiconductor. The series offers various voltage ratings from 3.3V to 100V with consistent mechanical dimensions in the DO-41 case. The 'BK' suffix indicates a black cathode band marking, while 'PBFREE' denotes lead-free plating.
