MMDT4401 NPN Bipolar Transistor SOT-363
MMDT4401 is a dual NPN small-signal surface-mount transistor in SOT-363 package, using epitaxial planar die construction. It is designed for low-power signal amplification and high-speed switching in compact electronic equipment. With a maximum collector current of 600mA, VCEO of 40V, and high fT up to 250MHz, it provides reliable performance in space‑constrained applications.
Our Advantages
- Dual NPN transistor in one compact package, saving PCB space and BOM cost
- Ultra-small SOT-363 surface-mount package for high-density circuit design
- Epitaxial planar process for stable and consistent electrical performance
- Wide DC current gain range for flexible switching and amplification
- High transition frequency up to 250MHz for high-speed signal applications
- Wide operating temperature range for industrial and consumer electronics
- RoHS compliant, tape-and-reel packaging for automatic SMT assembly
