Nexperia USA Inc. PSMN020-30MLCX

Overview

PSMN020-30MLCX from Nexperia is a logic-level enhancement-mode N-channel MOSFET in LFPAK33 (SOT1210) package, rated for 30 V V_DS, 18.1 mΩ R_DS(on) at V_GS = 10 V and T_j = 25 °C, and optimized for 4.5 V gate drive. It delivers 31.8 A continuous drain current at T_mb = 25 °C and supports high-efficiency DC-to-DC converters, synchronous buck regulators, and load switching in industrial and communications equipment.

For engineers reviewing the PSMN020-30MLCX datasheet, PSMN020-30MLCX pinout, PSMN020-30MLCX application, or PSMN020-30MLCX equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and confirmed alternative parts with documented functional differences - all derived from Nexperia's official product data sheet dated 4 September 2012.

Technical Context

This MOSFET uses TrenchMOS technology to achieve ultra-low gate charge (Q_G(tot) = 4.6 nC at V_GS = 4.5 V) and minimized output charge (Q_OSS = 2.3 nC), enabling fast switching with reduced switching losses. Its R_DS(on) remains stable across temperature due to low ΔV_GS(th)/ΔT (−3.5 mV/K) and exhibits strong thermal coupling via a low R_th(j-mb) of 4.32 K/W.

The device integrates a robust source-drain diode (V_SD = 0.89 V at I_S = 5 A, T_j = 25 °C) with fast reverse recovery (t_rr = 13.5 ns, Q_r = 5.1 nC), supporting synchronous rectification. Its avalanche ruggedness (E_AS = 7.7 mJ, unclamped) and peak pulsed drain current (I_DM = 127 A) support transient-heavy power stages.

FAQ

What is the maximum continuous drain current for PSMN020-30MLCX at 100 °C mounting base temperature?

The maximum continuous drain current is 22.5 A at T_mb = 100 °C and V_GS = 10 V, as specified in Table 4 (Limiting values). This reflects thermal derating due to reduced heat dissipation capability at elevated temperatures, and aligns with the derating curve in Figure 1 of the datasheet.

Does PSMN020-30MLCX have an integrated body diode, and what are its key parameters?

Yes, it includes a source-drain diode with V_SD = 0.89 V at I_S = 5 A and T_j = 25 °C, reverse recovery time t_rr = 13.5 ns, and recovered charge Q_r = 5.1 nC under specified test conditions (IS = 5 A, dI_S/dt = −100 A/µs, V_DS = 15 V). These values support synchronous rectification in buck converters.

Can PSMN020-30MLCX be used with a 3.3 V gate driver?

Yes - its gate-source threshold voltage V_GS(th) is 1.62 V typical (1.05–1.95 V range), and R_DS(on) is characterized down to V_GS = 4.5 V. At 3.3 V, the device conducts but with elevated R_DS(on); full enhancement requires ≥4.5 V. For reliable operation, use with 3.3 V logic is feasible only if load current is limited and thermal margin is verified.

What is the thermal resistance from junction to mounting base, and how should it be applied in layout design?

R_th(j-mb) is 4.32 K/W typical, measured from junction to the exposed mounting base (drain pad). To realize this value, the mounting base must be soldered to ≥200 mm² of 2 oz copper with ≥6 thermal vias (0.3 mm diameter, 0.8 mm pitch). Layouts omitting this copper area will see significantly higher junction temperatures under load.
