Nexperia USA Inc. PSMN2R0-30PL,127

Overview

PSMN2R0-30PL from Nexperia is a logic-level N-channel enhancement-mode MOSFET in TO-220AB (SOT78) package, rated for 30 V V_DS, 2.1 mΩ R_DS(on) at V_GS = 10 V and T_j = 25 °C, and qualified to 175 °C junction temperature. It delivers high-efficiency switching in high-current DC-DC converters and motor control stages where low conduction loss and direct 3.3 V/5 V gate drive compatibility are required.

For engineers reviewing the PSMN2R0-30PL datasheet, PSMN2R0-30PL pinout, PSMN2R0-30PL application, or PSMN2R0-30PL equivalent, key selection criteria include its 2.1 mΩ on-resistance at 10 V gate drive, 100 A continuous drain current capability at T_mb = 25 °C, avalanche energy rating of 555 mJ, thermal resistance R_th(j-mb) of 0.41 K/W, and logic-level gate threshold (V_GS(th) = 1.3–2.15 V).

Technical Context

This MOSFET employs planar silicon technology optimized for low R_DS(on) and fast switching with minimal gate charge (Q_G(tot) = 117 nC at 10 V). Its gate-drain charge Q_GD is 16 nC, supporting controlled turn-on/turn-off behavior in hard-switched topologies.

The device integrates an intrinsic body diode with V_SD = 0.76 V at I_S = 25 A and t_rr = 49 ns, enabling synchronous rectification and freewheeling in buck and half-bridge configurations without external diode supplementation.

FAQ

What is the maximum continuous drain current for PSMN2R0-30PL at 100 °C mounting base temperature?

At T_mb = 100 °C, the normalized current derating curve (Figure 1) shows approximately 60 % of the 100 A rating at 25 °C, yielding ~60 A continuous drain current. This reflects thermal limitation of the TO-220AB package, not device failure - proper heatsinking restores full rating.

Can PSMN2R0-30PL be driven directly from a 3.3 V microcontroller GPIO without a gate driver?

Yes. With V_GS(th) as low as 1.3 V and R_DS(on) = 2.0 mΩ at V_GS = 4.5 V, the device achieves usable conduction at 3.3 V. However, full 100 A capability requires V_GS ≥ 10 V; for 3.3 V-only operation, limit I_D to ≤40 A to maintain R_DS(on) < 3.5 mΩ.

Is the mounting base electrically isolated from the drain terminal?

No. Per pinning information and package outline, the mounting base (mb) is internally connected to the drain (Pin 2). Electrical isolation from heatsink is mandatory unless the heatsink is referenced to the drain potential - use insulating pads or shoulder washers in grounded-heatsink designs.

What is the safe operating area (SOA) limitation at 10 µs pulse width and 24 V V_DS?

From Figure 3, at V_DS = 24 V and t_p = 10 µs, the SOA limit is ~350 A. This exceeds the 943 A peak drain current rating (Table 4), confirming robust short-pulse capability - design must ensure gate drive strength and layout inductance do not cause voltage overshoot beyond 30 V.
