DMP21D6UFB4-7B Description

Short technical summary and product information.

DMP21D6UFB4-7B is a 20V P-Channel enhancement mode MOSFET manufactured by Diodes Incorporated. It delivers a continuous drain current of 580mA at 25°C with a gate-source voltage of -4.5V. The device features maximum drain-source on-resistance of 1Ω at 4.5V gate drive, 1.5Ω at 2.5V, and 2Ω at 1.8V, enabling low-voltage logic operation. Gate threshold voltage is 1V maximum at 250µA drain current.

Designed for high efficiency power management, this MOSFET has fast switching speed and low gate charge of 0.8nC. It is ESD protected and operates over a junction temperature range of -55°C to +150°C. Maximum power dissipation is 510mW at 25°C ambient.

The device is housed in an ultra-small X2-DFN1006-3 package (3-XFDFN) with a footprint of 0.6mm² and 0.4mm profile, making it suitable for low-profile portable electronics. The package is surface mount, with NiPdAu over copper leadframe terminals. It is lead-free, halogen-free, and RoHS compliant.
