NSVF5490SKT3G

Overview

The NSVF5490SKT3G is an NPN silicon RF bipolar transistor manufactured by onsemi, designed for high-frequency applications. It operates within a maximum collector-emitter voltage of 10 V and supports a continuous collector current of 30 mA. The device features a transition frequency (fT) of 8 GHz and a maximum operating frequency of 1.5 GHz. Packaged in a compact SOT-623 surface-mount format measuring 1.4 x 0.8 x 0.58 mm, it offers low noise performance with a power dissipation rating of 100 mW. The component is qualified under AEC-Q101 standards and functions reliably across a temperature range from -55 °C to +150 °C.

Feature Summary

• Optimized for UHF to S-Band low-noise amplifier applications
• High transition frequency supporting RF signal processing
• Automotive-grade qualification ensuring reliability in harsh environments

Applications

• Low-noise amplification in UHF to S-Band receiver front-ends
• RF signal conditioning in automotive communication systems
• Mobile device up-conversion and down-conversion stages

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and AEC-Q101 automotive qualification requirements prior to integration. Ensure the selected variant matches the required lead-free manufacturing processes and environmental regulations applicable to the target deployment region.

Selection Notes

Select this component when designing circuits requiring high-frequency operation up to 8 GHz with minimal noise figure. Consider the SOT-623 footprint constraints and thermal management capabilities given the 100 mW power dissipation limit. Evaluate the 10 V collector-emitter voltage rating against peak signal swings to prevent breakdown during transient conditions.
