MMBT918_R1_00001

Overview

The MMBT918_R1_00001 is an NPN silicon VHF/UHF transistor manufactured by Panjit International Inc. in a SOT-23 plastic case. It operates with a collector-emitter voltage (VCEO) of 50V and a collector-base voltage (VCBO) of 30V. The device supports a continuous collector current of 100mA and dissipates up to 225mW at 25°C ambient temperature. Key electrical parameters include a DC current gain (hFE) ranging from 100 to 600 at IC=0.4mA, and a saturation voltage (VCE(sat)) of 0.4V maximum at IC=10mA. The component is RoHS compliant and halogen-free.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packing configuration. The R1 suffix indicates Tape and Reel packaging on a 7-inch reel. Confirm compliance requirements such as RoHS status and material declarations directly with the manufacturer or authorized distributors before finalizing procurement specifications.

Selection Notes

Select this component for low-voltage, high-frequency NPN switching or amplification tasks requiring a compact SOT-23 footprint. Ensure the operating collector current remains within the 100mA limit and that thermal dissipation does not exceed 225mW. Verify that the required current gain falls within the specified 100 to 600 range for the intended bias conditions.
