DMP2110UW-13

Overview

The DMP2110UW-13 is a P-channel enhancement mode MOSFET manufactured by Diodes Incorporated in an SOT323 package. It features a drain-source voltage (BVDSS) of -20V and a maximum continuous drain current (ID) of -2.0A at +25°C. The device offers low on-state resistance, specified as 100mΩ max at VGS = -4.5V and ID = -1.5A, or 160mΩ max at VGS = -1.8V and ID = -1.0A. Key electrical parameters include a gate threshold voltage (VGS(TH)) ranging from -0.4V to -0.9V, total gate charge (Qg) of 6.0nTyp, and input capacitance (Ciss) of 443pTyp. Thermal characteristics include a junction-to-ambient thermal resistance (RθJA) of 253°C/W for standard mounting.

Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the 10,000-unit tape and reel packaging configuration. Confirm that the component meets the required automotive quality standards if applicable, as standard parts may differ from AEC-Q100 qualified variants. Ensure the procurement channel is authorized to guarantee product authenticity and traceability according to manufacturer guidelines.

Selection Notes

Select this component for applications requiring a compact SOT323 footprint with a -20V rating. Evaluate the RDS(ON) specifications against the system's gate drive voltage; performance varies significantly between -4.5V and -1.8V gate biases. Consider the thermal resistance of 253°C/W when designing heat dissipation strategies for continuous operation near the maximum current limits.

Part Context

This part belongs to the DMP series of P-channel MOSFETs from Diodes Incorporated. The 'UW' designation indicates the SOT323 surface-mount case style. The '-13' suffix specifically denotes the 10,000-piece tape and reel packaging option, distinguishing it from other quantities like the 3,000-piece '-7' variant.

Replacement Considerations

Check datasheets for alternative P-channel MOSFETs in SOT323 packages with compatible -20V ratings and similar RDS(ON) values. Verify pinout compatibility (Gate, Source, Drain) and ensure thermal resistance characteristics meet the application's cooling requirements before substitution.
