Diodes Incorporated DMP22D4UDA-7B

Overview

DMP22D4UDA-7B from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET in an ultra-small X2-DFN0806-6 package (0.8 mm × 0.6 mm), rated for -20 V V_DSS, 1.9 Ω R_DS(ON) @ V_GS = -4.5 V, and -328 mA continuous drain current at +25°C. It serves as a compact, low-threshold switching device for space-constrained power management and analog signal routing in portable electronics.

For engineers reviewing the DMP22D4UDA-7B datasheet, DMP22D4UDA-7B pinout, DMP22D4UDA-7B application, or DMP22D4UDA-7B equivalent, key selection criteria include its -1.0 V max gate threshold voltage, ESD-protected gate, low input capacitance (28.5 pF), fast switching times (t_D(ON) = 5.2 ns), and thermal resistance of 407 °C/W on FR-4 PCB.

Technical Context

This dual MOSFET integrates two independent P-channel devices in a single die with shared thermal path and isolated source terminals (S1/S2). Each channel features a low-voltage gate drive capability down to -1.5 V, enabling direct interface with 1.8 V and 2.5 V logic systems without level shifting.

Its design emphasizes low R_DS(ON) stability over temperature (±15% variation from -55°C to +150°C at V_GS = -4.5 V) and robust gate oxide protection via integrated diodes per channel, supporting reliable operation in noisy or transient-prone environments such as battery-powered sensor nodes and USB peripheral power switches.

FAQ

What is the maximum safe operating junction temperature for DMP22D4UDA-7B?

The absolute maximum junction temperature is +150°C, and the device is characterized for stable R_DS(ON) performance across -55°C to +150°C. Thermal derating begins above +70°C ambient, with continuous drain current reduced to -262 mA at +70°C per channel per datasheet Note 5.

Can DMP22D4UDA-7B be used in back-to-back configuration for reverse-current blocking?

Yes-its dual independent P-channel structure with isolated sources (S1 and S2) supports standard back-to-back connection for bidirectional blocking in battery protection circuits. Each channel must be driven with identical gate signals, and the combined R_DS(ON) is additive (e.g., ~3.8 Ω total @ -4.5 V).

Is the thermal pad on the X2-DFN0806-6 package electrically connected?

No-the exposed thermal pad is not electrically connected to any internal node. It is intended solely for thermal conduction to the PCB and must be soldered to a copper pour for optimal heat dissipation; no electrical tie to ground or other nets is required or recommended.

Does DMP22D4UDA-7B support 1.2 V logic-level gate drive?

No-while V_GS(TH) is guaranteed ≤ -1.0 V, the device does not fully enhance at -1.2 V due to insufficient overdrive margin. Minimum recommended V_GS is -1.5 V (R_DS(ON) = 3.4 Ω), and -1.8 V or lower is advised for <2 Ω operation in production designs.
