For the circuit design of products with a 12V input, a higher voltage safety factor is required. This domestically produced MOS tube newly launched to the market in 2025 solves the aforementioned problems with its parameter performance of BVDSS_typ=55V.

Its innovative design is based on an existing mature product system, allowing it to be stably and reliably applied in various 12V input inverters and 12V input audio power supplies.

This is the FHP1404V MOS tube, the first product launched by Hong Semiconductor. It has the above-mentioned characteristics and also features extremely low on-resistance, enabling seamless replacement of CS1404, IRF1404PbF, HY4004, FTP1404 field effect transistors.

As an N-channel enhancement-mode field-effect transistor, FHP1404V adopts advanced trench technology, reducing conduction losses, improving switching performance, and increasing avalanche energy.

This transistor can be used in various power switch circuits. Its product form is TO-220 packaging, complying with the JEDEC standard, and meets RoHS and REACH standards environmentally, as well as being halogen-free and eco-friendly.
