2SC4618TLP

Overview

The 2SC4618TLP is an NPN RF transistor manufactured by Rohm Semiconductor, designed for high-frequency amplifier applications. 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 an EMT3 (SOT-416) surface-mount package. The component exhibits a minimum DC current gain (hFE) of 82 at 1mA and 6V. It functions within a junction temperature range up to 150°C and complies with RoHS3 standards.

Feature Summary

• Optimized for high-frequency amplification circuits
• Compact surface-mount EMT3 packaging for space-constrained designs
• High thermal stability with a 150°C maximum junction temperature

Applications

• RF signal amplification stages
• High-frequency communication equipment
• Consumer electronics requiring small form-factor transistors

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to ensure correct packaging configuration. Confirm that the EMT3 package variant matches the intended PCB footprint requirements. Check for any recent product change notices or lifecycle status updates from Rohm Semiconductor prior to finalizing procurement plans.

Selection Notes

Select this component when a low-voltage, high-speed NPN transistor is required for RF applications. Ensure the design accommodates the 150mW power dissipation limit and the 50mA current constraint. Verify compatibility with the SOT-416/EMT3 land pattern during the schematic capture phase.

Part Context

This part belongs to the 2SC4618 series of bipolar junction transistors. It is distinct from higher-voltage variants like the 2SC4617, which offers 50V breakdown. The TLP suffix typically denotes a specific tape-and-reel packaging format distributed by authorized channels.

Replacement Considerations

Direct substitutes may include other NPN RF transistors in the SOT-416 package with similar Vceo and fT ratings. Verify pinout compatibility and electrical parameters before swapping.
