UM7506F

RF Diode Overview

The UM7506F is a high-power silicon PIN diode from the UM7500 series, manufactured by Microchip Technology. It features a hermetic fused-in-glass construction with a reverse voltage rating of 600V at 0.5 µA leakage current. The device supports a maximum power dissipation of 10W in stud packages and operates within a temperature range of -65°C to +175°C. Key electrical parameters include a typical total capacitance of 1.0 pF at 100V/1MHz and a series resistance of 1.0 Ohm at 50mA/100MHz. Carrier lifetime is specified between 2.5 µs and 3.5 µs.

RF Diode Feature Summary

• Hermetically sealed fused-in-glass construction for reliable high-power operation
• Low leakage distortion achieved through controlled I-region thickness and high carrier lifetime
• Metallurgically bonded design ensuring thermal matching and stability
• Capable of meeting MIL-STD-750 screening requirements for military applications

RF Diode Applications

• RF and microwave switch circuits
• Attenuator circuits
• High-end medical equipment such as MRI and CAT scan systems

RF Diode Procurement Notes

Verify the specific package style (e.g., Stud or Surface Mount) required for the application, as the datasheet lists multiple mechanical configurations with varying thermal characteristics. Confirm RoHS compliance status if applicable, noting that standard packaging may differ from compliant variants like the UMX series. Ensure sourcing channels provide original manufacturer documentation to validate part authenticity and revision history.

RF Diode Selection Notes

Select the UM7506F when a 600V reverse voltage rating is necessary for RF switching or attenuation tasks. Consider the available package styles based on thermal management needs; stud packages offer higher power dissipation capabilities compared to surface mount options. Evaluate the need for MIL-STD-750 screening if the deployment environment requires rigorous military-grade reliability standards.

RF Diode Part Context

The UM7506F belongs to the UM7500 series of power PIN diodes produced by Microsemi, now part of Microchip Technology. This series utilizes advanced silicon wafer bonding and junction passivation techniques to achieve low leakage and stable reverse characteristics. The family includes variants with ratings from 100V to 1400V, sharing common structural benefits like void-less construction and compatibility with automatic insertion equipment.

RF Diode Replacement Considerations

For RoHS-compliant alternatives, consider the UMX7500 series (e.g., UMX7506B). Verify mechanical footprint compatibility if replacing a specific package style, as dimensions vary significantly between stud and surface-mount versions within the same electrical family.
