2SC5661T2LP

Overview

The ROHM 2SC5661T2LP is a high-frequency NPN bipolar junction transistor designed for surface-mount applications. It features a VMT3 package and operates with a collector-emitter voltage of 20V and a collector current of 50mA. The device exhibits a typical transition frequency (fT) of 1.5GHz, ensuring effective performance in RF circuits. Key electrical characteristics include a DC current gain (hFE) ranging from 82 to 180 and a low collector-base time constant (rbb'·Cc) of approximately 6ps. The component supports an operating temperature range from -55°C to +150°C.

Feature Summary

High transition frequency suitable for RF amplifier applications
Low noise figure and small collector-base time constant
Compact surface-mount packaging for automated assembly

Applications

High-frequency amplification stages
RF signal processing circuits
Communication equipment front-ends

Procurement Notes

Verify the specific ordering suffix T2L corresponds to the required tape-and-reel quantity of 8000 units. Confirm that the VMT3 package dimensions align with the target PCB footprint. Ensure the supply status remains acceptable for production needs, as availability may vary based on manufacturing schedules.

Selection Notes

Select this component when a high fT and low noise figure are critical for the design. Verify that the 20V collector-emitter voltage rating meets the circuit's maximum operating conditions. Consider the thermal dissipation limits of 0.15W and the small package size during layout planning.

Part Context

This part belongs to a family of high-frequency transistors including the 2SC4725, 2SC4082, and 2SC3837K. While sharing similar electrical specifications, these variants differ in package types such as EMT3, UMT3, and SMT3. The 2SC5661 specifically utilizes the VMT3 package configuration.

Replacement Considerations

Direct pin-compatible alternatives within the same series include the 2SC4725, 2SC4082, and 2SC3837K. Note that these substitutes utilize different packages (EMT3, UMT3, SMT3), requiring PCB layout adjustments if used as replacements.
