Procurement Notes

Verify component authenticity and lot traceability directly with Taiwan Semiconductor or authorized distributors before procurement. Confirm that the specific suffix matches project requirements for packaging and qualification standards. Ensure compliance with RoHS and REACH directives as specified in the official datasheet. Request factory documentation to validate supply chain integrity and manufacturing origin.

Selection Notes

Select this component when a 75 V regulated voltage is required in an axial package. Consider the 175 Ohm impedance for noise-sensitive designs. Verify thermal management capabilities for 1 W dissipation in the target enclosure. Ensure the operating environment falls within the specified -55 °C to +150 °C junction temperature range.

Part Context

This part belongs to the 1N47xx series of power Zener diodes from Taiwan Semiconductor. These components are widely used in industrial and automotive sectors for their reliability and standardized form factor.
