Operation: Require a gate-source voltage (VGS) to create a conductive channel. In their default state (VGS = 0), they remain non-conductive (normally off).
Applications: Ideal for digital logic, power switches, and amplifiers. For example, our YFW150P04AS P-channel MOSFET (150A, 40V) excels in automotive power management systems, ensuring efficient energy conversion with low RDS(ON) (5.4mΩ) .
Advantages: High switching speed, low power consumption, and compatibility with modern integrated circuits.
Operation: Feature a pre-formed channel at VGS = 0, allowing current flow (normally on). A negative VGS is needed to deplete the channel and turn them off.
Applications: Commonly used in voltage regulators and analog circuits. For instance, in medical devices, our depletion-mode MOSFETs enable stable signal amplification while maintaining low noise levels .
Advantages: Simplified circuit design and fail-safe operation in critical systems
Feature | Enhancement Mode | Depletion Mode |
---|
Default State | Off (VGS = 0) | On (VGS = 0) |
Threshold Voltage | Positive (VGS(th) > 0) | Negative (VGS(th) < 0) |
Typical Use Cases | Digital logic, power switching | Voltage regulation, analog amplifiers |
