Overview
The 2SC4784YA-TR-E is an NPN small-signal bipolar junction transistor designed for high-frequency amplifier applications, specifically targeting UHF bands. Manufactured by Renesas Electronics Corporation, this component utilizes a CMPAK package configuration with three leads. It supports lead-compliant and lead-free manufacturing standards. The device is characterized by a collector current rating of 0.02 A at 100 °C, ensuring stable performance in RF signal processing circuits requiring compact form factors.
Feature Summary
- Optimized for high-frequency amplification in UHF application scenarios
- NPN polarity configuration within a compact CMPAK surface-mount package
- Supports lead-free and lead-compliant manufacturing processes
Applications
- UHF band high-frequency amplifier circuits
- RF signal processing modules
- Small-signal amplification stages
Procurement Notes
Verify the specific ordering suffix to confirm package type and tape-and-reel specifications. Ensure compatibility with existing design-in requirements regarding lead compliance status. Cross-reference the CMPAK package dimensions against PCB footprint constraints. Confirm that the target application aligns with the specified UHF frequency range and NPN configuration before finalizing procurement orders.
Selection Notes
Select this component when a small-signal NPN transistor is required for UHF frequency operations. The CMPAK package offers a compact solution for space-constrained designs. Consider the 0.02 A current rating for appropriate biasing conditions. Verify that the manufacturer's lead-free options meet environmental regulations applicable to the end product deployment.
Part Context
This part belongs to the 2SC4784 series of small-signal bipolar transistors intended for high-frequency use. The 'YA-TR-E' suffix typically denotes specific packaging and environmental compliance attributes defined by Renesas Electronics. It serves as a specialized RF component distinct from general-purpose switching transistors, focusing on amplification capabilities within the UHF spectrum.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official Renesas Electronics resources or authorized distributors for qualified alternatives. Ensure any replacement matches the CMPAK package, NPN polarity, and UHF application requirements.
