HFA3127B96

Overview

The HFA3127B96 is an ultra-high frequency transistor array fabricated using the Renesas complementary bipolar UHF-1 process. It consists of five dielectrically isolated NPN transistors on a common monolithic substrate, housed in a 16-SOIC package. The device features a transition frequency (fT) of 8GHz and a maximum collector-emitter voltage (VCEO) of 12V. Key electrical parameters include a maximum continuous collector current of 65mA, a minimum DC current gain (hFE) of 40 at 10mA/2V, and a typical noise figure of 3.5dB at 1GHz. Maximum power dissipation is rated at 150mW, with a junction temperature limit of 150°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
• RF mixer applications
• Ultra-high frequency signal processing

Procurement Notes

Verify component status as discontinued or obsolete through official manufacturer channels before design finalization. Confirm RoHS compliance details, as specific suffixes may indicate lead-free or non-compliant variants. Validate package dimensions against PCB footprint requirements to ensure mechanical compatibility during procurement.

Selection Notes

Select this component when five matched NPN transistors are required within a single package for space-constrained RF designs. Ensure the operating frequency aligns with the 8GHz transition frequency specification. Verify that the 12V collector-emitter voltage rating meets the circuit's biasing requirements and that the 16-SOIC package is suitable for the intended assembly method.

Part Context

The HFA3127B96 belongs to the HFA3127 family of ultra-high frequency transistor arrays manufactured by Intersil, now part of Renesas Electronics. This series includes variations such as the HFA3046, HFA3096, and HFA3128, which differ in transistor polarity combinations. The B96 suffix typically denotes the specific tape-and-reel packaging configuration for surface-mount assembly.

Replacement Considerations

Direct substitutes include other members of the HFA3127 family, such as the HFA3127BZ, depending on packaging preferences. Verify pinout compatibility and electrical specifications before replacing. Consult manufacturer documentation for any updated equivalents or cross-reference recommendations due to the component's discontinued status.
