Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service. 

Description:
The MMBT4403 is a versatile PNP bipolar junction transistor (BJT) known for its compact size and efficient performance. Enclosed in a standard SOT-23 package, this transistor is designed to handle moderate current and power dissipation with reliability. It features a collector-emitter voltage (Vceo) rating of -40V, a maximum collector current (Ic) of -0.6A, and a power dissipation (Pd) capability of 0.35W. With a transition frequency (fT) of 200MHz, the MMBT4403 offers excellent high-frequency response, making it suitable for applications requiring fast switching and amplification.

Features:
● Epitaxial planar die construction.
● Complementary NPN type available (MMBT4401).
● Also available in lead free version.
● Ideal for medium power amplification and switching

Applications:
