Overview
The 2SC4618TLN is an NPN high-frequency amplifier transistor manufactured by Rohm Semiconductor. It operates with a maximum collector-emitter voltage of 25V and supports a continuous collector current of 50mA. The device features a transition frequency of 300MHz and a maximum power dissipation of 150mW. It is housed in the EMT3 (SOT-416) surface-mount package, suitable for compact designs. The component maintains a minimum DC current gain of 82 at 1mA and 6V, ensuring reliable signal amplification in RF applications.
Feature Summary
- Designed for high-frequency amplification tasks within radio frequency circuits
- Utilizes a compact EMT3 surface-mount package for space-constrained layouts
- Provides stable DC current gain characteristics for consistent signal processing
Applications
- RF signal amplification stages
- High-frequency oscillator circuits
- General-purpose small-signal amplification
Procurement Notes
Verify the specific suffix TLN against official Rohm documentation to confirm tape-and-reel packaging details and exact binning specifications. Ensure compatibility with standard SMD reflow profiles and check for RoHS compliance status in the latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component when a low-voltage, high-speed NPN transistor is required for frequencies up to 300MHz. Compare the 25V breakdown voltage and 50mA current limits against circuit requirements. Consider the EMT3 footprint constraints and thermal dissipation capabilities relative to the 150mW power rating during board layout planning.
Part Context
This part belongs to the 2SC4618 series of high-frequency amplifier transistors from Rohm. It shares core electrical parameters with variants like the 2SC4618TLP but may differ in packaging or reel specifications. The series targets general RF applications requiring small form factors and reliable performance at VHF frequencies.
Replacement Considerations
Direct substitutes include other 2SC4618 variants from Rohm with identical electrical ratings but different packaging suffixes. Cross-manufacturer replacements must match the 25V Vceo, 50mA Ic, 300MHz fT, and EMT3/SOT-416 package dimensions to ensure mechanical and electrical compatibility.
