DMP21D0UFB4-7B Description

Short technical summary and product information.

The DMP21D0UFB4-7B is a 20V P-Channel enhancement mode MOSFET from Diodes Incorporated, designed for high-efficiency power management in portable electronics. It delivers a continuous drain current of 770mA at 25°C and features a low on-resistance of 495mOhm max at Vgs=4.5V, with additional Rds(on) ratings of 690mOhm at 2.5V and 960mOhm at 1.8V for flexible drive voltage compatibility. The device offers a low gate threshold voltage of 1V max, enabling operation from low-voltage logic levels.

 

With a gate charge of 1.54nC and input capacitance of 80pF, the MOSFET supports fast switching speeds suitable for compact power converters and load switches. The gate is ESD protected, enhancing robustness in handling and assembly. The device operates over a junction temperature range of -55°C to 150°C and dissipates up to 430mW.

 

Packaged in the ultra-small X2-DFN1006-3 (3-XFDFN) case measuring just 0.6mm² footprint with a 0.4mm profile, it is ideal for space-constrained, low-profile applications. The package uses a green molding compound and is fully RoHS compliant and halogen-free, meeting environmental requirements.
