Product details

Overview

PSMN3R4-30PL from Nexperia is a logic-level N-channel MOSFET in TO-220AB (SOT78) package, rated for 30 V V_DS, 3.4 mΩ R_DS(on) at V_GS = 10 V and T_j = 25 °C, 100 A continuous drain current at T_mb = 25 °C, and qualified to 175 °C junction temperature. It serves as a high-efficiency power switch in DC-DC converters and server power supplies.

For engineers reviewing the PSMN3R4-30PL datasheet, PSMN3R4-30PL pinout, PSMN3R4-30PL application, or PSMN3R4-30PL equivalent, this device is selected for low-R_DS(on) switching in thermally demanding industrial and communications systems where logic-level gate drive compatibility and avalanche ruggedness (200 mJ) are critical.

Technical Context

This MOSFET employs planar silicon technology with optimized channel geometry to achieve low conduction loss while maintaining robust switching performance. Its gate threshold voltage (V_GS(th)) ranges from 1.3 V to 2.15 V at 25 °C and drops to 0.5 V at 175 °C, enabling reliable turn-on across wide temperature ranges with standard 3.3 V/5 V logic drivers.

Thermal design is supported by a typical R_th(j-mb) of 0.65 K/W and mounting-base–referenced power derating curves. The integrated source-drain diode exhibits 0.7 V forward voltage at 10 A and 25 °C, with 36 ns reverse recovery time and 28 nC recovered charge-key for synchronous rectification and freewheeling applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage before avalanche; defines use in ≤24 V nominal bus systems with margin.
R_DS(on)	3.4 mΩ @ V_GS = 10 V, T_j = 25 °C - Enables <1 W conduction loss at 50 A, critical for high-current power stages.
I_D	100 A @ T_mb = 25 °C - Continuous current rating limited by TO-220AB package thermal capacity, not die.
Q_G(tot)	31 nC @ V_GS = 4.5 V - Low gate charge supports efficient 100–500 kHz switching with minimal driver loss.
E_AS	200 mJ unclamped avalanche energy - Confirmed ruggedness for inductive load switching without external snubbers.
V_GS(th)	1.7 V typ @ 25 °C - Ensures full enhancement with 3.3 V logic-level sources, reducing need for level shifters.
R_th(j-mb)	0.65 K/W typ - Direct thermal path to heatsink enables compact thermal design in space-constrained power modules.

Pinout & Package

TO-220AB (SOT78) plastic single-ended package with heatsink-mounted base; 3 leads; mounting base electrically connected to drain. Dimensions per IEC/JEDEC SC-46 outline.

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal; requires ≤20 V absolute max; 1 Ω internal gate resistance limits dV/dt-induced ringing.
2 (D)	Drain	Main high-side power terminal; electrically tied to mounting base-requires insulated heatsink or isolation hardware.
3 (S)	Source	Power return and reference node; forms common ground for gate drive and current sensing in low-side configurations.

Key Features

Feature	Design Value
Logic-level gate drive compatibility	Turns fully on with 3.3 V or 5 V microcontroller outputs-eliminates need for dedicated gate drivers in cost-sensitive designs.
Low R_DS(on) at elevated temperature	6.46 mΩ @ V_GS = 10 V, T_j = 175 °C-ensures stable conduction loss under sustained thermal stress in server PSUs.
High avalanche energy rating	200 mJ unclamped E_AS-supports reliable operation in motor control and relay driving where inductive kickback occurs.
Optimized dynamic characteristics	Q_GD/Q_G(tot) ratio of ~0.26-reduces Miller effect, improving switching speed and reducing cross-conduction risk in half-bridge topologies.
Integrated source-drain diode	36 ns t_rr, 28 nC Q_r-enables efficient freewheeling in buck converters without external Schottky diode.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRF3205PBF	R_DS(on) = 8.0 mΩ @ 10 V; Q_G(tot) = 71 nC; T_j max = 175 °C; TO-220AB package.	Higher conduction and switching losses; less suitable for high-frequency, high-current DC-DC stages.	Select when cost is primary constraint and thermal margin allows higher R_DS(on)-not recommended for >200 kHz operation.
STP30NF20	V_DS = 200 V; R_DS(on) = 38 mΩ @ 10 V; Q_G(tot) = 45 nC; TO-220 package; logic-level compatible.	Higher voltage rating but significantly higher R_DS(on); unsuitable for low-voltage, high-current applications like server PSUs.	Choose only if system requires >100 V blocking; otherwise, PSMN3R4-30PL delivers superior efficiency at 30 V.

Compared with IRF3205PBF and STP30NF20, PSMN3R4-30PL offers the lowest R_DS(on) and gate charge in its 30 V class, delivering measurable efficiency gains in thermally constrained, high-current applications-making it the preferred choice for modern server and industrial power designs.

FAQ

Is PSMN3R4-30PL suitable for surface-mount assembly?

No. PSMN3R4-30PL uses a through-hole TO-220AB (SOT78) package with a metal mounting base designed for mechanical attachment to a heatsink. It is not compatible with reflow soldering or pick-and-place SMT processes. Thermal performance relies on direct mechanical mounting and thermal interface material.

What is the maximum safe operating temperature for continuous use?

The device is qualified for continuous operation up to 175 °C junction temperature (T_j). However, sustained operation above 150 °C requires careful thermal design due to R_DS(on) increase-typical R_DS(on) rises to 6.46 mΩ at 175 °C, doubling conduction loss versus 25 °C.

Does the mounting base require electrical isolation?

Yes. Pin 2 (Drain) and the mounting base are internally connected. When mounted to a heatsink, an electrically insulating pad or washer must be used unless the heatsink is intentionally referenced to the drain potential-failure to isolate risks short circuits in grounded-system layouts.

Can PSMN3R4-30PL replace older 30 V MOSFETs like IRF1404 in existing designs?

Yes, with verification. PSMN3R4-30PL offers lower R_DS(on) (3.4 mΩ vs. 4.0 mΩ), lower Q_G(tot) (31 nC vs. 131 nC), and identical TO-220AB footprint. Gate threshold is lower (1.7 V vs. 2.0 V), improving logic-level compatibility-but layout review for gate drive stability and thermal margin is required.
