As a widely used MOS tube product, PMOS refers to a MOS tube with N-type substrate and P-channel, which carries current by the flow of holes. PMOS has its unique characteristics, and the working area of conducting PMOS is divided into unsaturated area, critical saturation point and saturated area. PMOS has its unique advantages in applications such as DCDC converters, load switches and driving circuits. In this issue, Hottech introduces a P-channel MOS tube HKTQ30P03 packaged with PDFN3333, which is widely used in power supplies, converters, LEDs and power tools.

HKTQ30P03 features

HKTQ30P03 produced by Hottech has good electrical characteristics. Its drain-source voltage is -30V, gate-source voltage is -20V, continuous drain current is -60V, drain-source on-resistance is 0.0074Ω, minimum gate threshold voltage is -1V, maximum gate threshold voltage is -2V, dissipation power is 32mW, and its weight is about 0.012g.. This product has a very low on-resistance, which is suitable for the application of low-power DC-DC converter, and it can also play an important role in the application of load switch.

In packaging, HKTQ30P03 adopts PDFN3333 packaging, and the surface mount form is very suitable for small electronic design schemes, meeting the design requirements of customers for miniaturization, functional systematization and modular packaging.

Hottech's double-sided heat dissipation technology has excellent heat dissipation performance and excellent overall performance. This product encapsulated by PDFN3333 has excellent thermal conductivity, electrical properties and mechanical strength. At the same time, it has the characteristics of small volume, light weight and very thin, which is very suitable for miniaturized PCB design products.

Application of HKTQ30P03

HKTQ30P03 can be applied to chargers, adapters, DCDC converters, portable equipment load switches, battery switches and LED drivers.

In the reverse protection circuit, HKTQ30P03 produced by Hottech has smaller voltage drop, less power dissipation, lower power consumption and higher efficiency. The switching speed of HKTQ30P03 is extremely fast. When it is used as a power switch and a load switch, its working efficiency is high and the switching speed is very fast.

In the driving circuit of PMOS transistor, HKTQ30P03 transistor has very low on-resistance and low energy consumption, so it is very suitable as a power switch in DCDC converter circuit.

In a word, HKTQ30P03 produced by Hottech is a stable, reliable and low-power MOS transistor product, especially suitable for low-power scenarios. At the same time, the package of HKTQ30P03 is small and stable, which also leaves a lot of margin for engineers to design circuits, and it is a good choice for customers to purchase discrete devices.
