The DMZ0615E/DMX0615E series of depletion-mode MOSFETs from ARK Microelectronics utilize proprietary ultrahigh threshold voltage technology. These devices are designed for applications requiring stable voltage regulation, such as Quick Charge (QC4.0) and Type C PD chargers. They can function as a current or voltage source, providing stable power to loads and clamping output voltage to protect connected components. With input voltage capabilities up to 70V, they are suitable for power supplies for PWM ICs in flyback converters, offering a cost-effective alternative to traditional transistor and zener diode circuits.
