HFA3128RZ96

Overview

The HFA3128RZ96 is an ultra-high frequency transistor array fabricated using the Renesas complementary bipolar UHF-1 process. It consists of five dielectrically isolated PNP transistors on a common monolithic substrate, housed in a 16-lead QFN EP package measuring 3x3 mm. The device features a transition frequency (fT) of 5.5 GHz and a maximum collector-emitter voltage (VCEO) of 8 V. Key electrical parameters include a minimum DC current gain (hFE) of 20 at 10 mA/2 V, a continuous collector current of 65 mA, and a power dissipation rating of 150 mW. The emitter-base voltage (VEBO) is rated at 5.5 V. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Monolithic construction provides close electrical and thermal matching among the five integrated transistors.
• Dielectric isolation ensures stability and performance consistency in high-frequency environments.
• Full terminal access for each individual transistor allows for maximum application flexibility.

Applications

• High-frequency amplifier circuits
• Mixer applications requiring low noise performance

Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS compliance details as specified in official documentation. Check moisture sensitivity level handling requirements prior to assembly. Validate package dimensions against PCB footprint specifications. Ensure supplier provides valid traceability records for quality assurance purposes.

Selection Notes

Select this component when designing circuits requiring matched PNP arrays with a 5.5 GHz transition frequency. Consider the 16-QFN 3x3mm package for space-constrained layouts. Evaluate the 8 V VCEO limit against circuit voltage swings. Compare noise figure specifications against alternative NPN or mixed-polarity arrays if different signal paths are required.

Part Context

This part belongs to the HFA3128 series, which includes variants like the HFA3128B in SOIC packaging. The RZ suffix indicates the specific QFN tape-and-reel packaging configuration. It shares the same core transistor architecture as other members of the HFA3046, HFA3096, and HFA3127 families, differing primarily in polarity and package type.

Replacement Considerations

Publicly confirmed substitute part numbers are not available. The HFA3128B offers similar electrical characteristics but utilizes a 16-SOIC package instead of QFN. Designers must evaluate pinout compatibility and thermal management differences when considering alternative packages within the same family.
