Procurement Notes
Verify the specific suffix 'B0G' against official manufacturer documentation to confirm exact marking codes and packaging details. Ensure compliance requirements such as RoHS status are confirmed via the latest datasheet. Cross-reference ordering information directly with Taiwan Semiconductor to validate availability and specifications before procurement.
Selection Notes
Select this component for applications requiring a stable 16V reference in axial leaded packages. Consider the 1W power rating and thermal resistance when designing heat dissipation strategies. Verify that the ±5% voltage tolerance meets circuit precision requirements. Ensure the operating temperature range aligns with environmental conditions.
Part Context
This part belongs to the 1N47xx series of Zener voltage regulators produced by Taiwan Semiconductor. These devices utilize silicon planar technology and are housed in hermetically sealed glass DO-41 packages. The series offers a wide range of Zener voltages, typically from 3.3V to 56V, providing reliable performance for general-purpose regulation tasks.
Replacement Considerations
Compatible substitutes include parts from other manufacturers offering identical 16V, 1W, DO-41 specifications. Examples include Fairchild's 1N4745A_T50A or onsemi's 1N4745A. Verify pinout compatibility and ensure equivalent electrical parameters such as dynamic impedance and leakage current.
