UM9441HR2/TR

Overview

The UM9441HR2/TR is a silicon PIN diode manufactured by Microchip Technology. It features a hermetic glass axial package designed for RF applications. The component has a peak reverse voltage rating of 100V and exhibits a junction capacitance of 10pF at 50V reverse bias and 1MHz frequency. This device is classified as a single PIN diode intended for high-frequency signal processing tasks.

Feature Summary

• Hermetic glass axial construction for environmental sealing
• Silicon PIN diode technology optimized for RF performance
• Low junction capacitance characteristics for high-speed switching

Applications

• RF signal switching circuits
• Attenuator networks
• Phase shifting applications

Procurement Notes

Verify the specific suffix TR against official Microchip documentation to confirm tape-and-reel packaging requirements. Confirm RoHS status details directly from the datasheet, as listed information may vary. Ensure the hermetic seal specifications meet the environmental constraints of the target application before finalizing procurement orders.

Selection Notes

Select this component when hermetic sealing is required for RF diodes operating at 100V peak reverse voltage. The low capacitance value supports high-frequency operations. Verify that the axial leaded package form factor aligns with the PCB layout and mounting constraints of the design.

Part Context

This part belongs to the PIN diode category within Microchip's semiconductor portfolio. It serves as a specialized component for radio frequency engineering, distinct from standard rectifier or zener diodes. The hermetic glass axial package distinguishes it from surface-mount alternatives in similar voltage classes.

Replacement Considerations

Cross-reference with other hermetic glass axial PIN diodes rated for 100V reverse voltage. Verify pin compatibility and capacitance values against equivalent parts from other manufacturers to ensure functional interchangeability in existing RF designs.
