AT-30533-TR2G

Overview

The AT-30533-TR2G is an NPN silicon bipolar transistor from the Agilent AT-30533 series, optimized for low current and low voltage operation. It utilizes a self-aligned-transistor process with a 3.2-micron emitter-to-emitter pitch to achieve high performance at 2.7 V. The device features a maximum operating frequency of 30 GHz, a collector-emitter breakdown voltage (VCEO) of 5.5 V, and a continuous collector current of 8 mA. It operates within a temperature range of -65°C to +150°C and dissipates up to 100 mW. Packaged in an SOT-23 format, this specific variant includes tape-and-reel packaging for automated assembly.

Feature Summary

• Optimized for battery-powered wireless applications through high performance at low voltage operation
• Utilizes a five-emitter finger interdigitated geometry for extremely fast switching and high gain
• Features nitride passivation for surface protection and gold metalization for reliability

Applications

• Low noise amplifiers (LNA) for 900 MHz, 1.8 GHz, and 2.4 GHz systems
• Gain stages and buffers in wireless markets
• Oscillators and active mixers in battery-operated devices

Procurement Notes

Verify the component against official datasheets to confirm lead-free status associated with the 'G' suffix. Ensure the ordering suffix matches the required reel size, as the TR2 designation indicates a 13-inch reel configuration. Cross-reference manufacturer part numbers to avoid confusion with bulk or alternative reel variants.

Selection Notes

Select this component when designing circuits requiring high gain and low noise figures at very low bias currents. It is specifically suited for 900 MHz pager applications and other low-voltage wireless systems where power efficiency is critical. Evaluate thermal derating requirements if the junction temperature exceeds 95°C.

Part Context

This transistor belongs to the Agilent AT-30533 series, which shares the same die design as the AT-30511 but differs in package configuration. While the AT-30511 uses a four-lead SOT-143 package, the AT-30533 utilizes a standard three-lead SOT-23 plastic package. Both are compatible with high-volume surface mount assembly techniques.

Replacement Considerations

The AT-30511 serves as a functional equivalent utilizing the identical semiconductor die, differing only in its four-lead SOT-143 package. Verify pinout compatibility and thermal dissipation characteristics before substituting between these two package styles.
