UMIL10

Overview

The UMIL10 is an NPN bipolar RF transistor designed for high-frequency applications in the 100MHz to 400MHz range. It features a maximum collector-emitter breakdown voltage of 30V and supports a continuous current of 1.5A. The device delivers a maximum power output of 28W with a typical gain of 10dB. It operates with a minimum DC current gain (hFE) of 10 at 200mA and 5V. The component utilizes a chassis stud mount package for thermal management.

Feature Summary

• Broadband design optimized for the 100-400 MHz frequency band
• Capable of operation in Class AB or C amplifier configurations
• High power handling capability up to 28W
• Chassis stud mount construction for efficient heat dissipation

Applications

• RF power amplification in communication systems
• Broadband transmitter stages
• Industrial RF heating equipment
• Test and measurement signal generation

Procurement Notes

Verify the specific manufacturer source, as Microsemi assets have undergone corporate restructuring. Confirm the part status is obsolete before procurement planning. Ensure the mounting surface preparation matches the stud mount requirements for proper thermal interface. Validate that the 30V rating aligns with the circuit's peak voltage demands to prevent breakdown.

Selection Notes

Select this component when broadband performance across 100-400MHz is required alongside high power output. Consider the stud mount package for thermal solutions where heatsink integration is feasible. Evaluate the 30V limit against system voltage spikes. Compare gain and noise characteristics against alternative transistors if lower noise figures are critical for the specific application bandwidth.

Part Context

The UMIL10 belongs to the category of bipolar RF transistors historically associated with Microsemi Corporation. These components were engineered for robust performance in demanding radio frequency environments. The product line typically serves industrial and commercial sectors requiring reliable high-power amplification. Availability may be limited due to the component's obsolete status.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements must be identified through independent cross-reference databases or by consulting distributor-specific equivalent lists. Verify pinout compatibility and thermal resistance specifications when sourcing alternatives.
