Product details

Overview

IRFH7934TR2PBF from Infineon Technologies is a 30V N-channel Trench MOSFET in PQFN 5×6 mm package, featuring R_DS(on) = 2.9 mΩ (typ) at V_GS = 10 V, Q_g = 20 nC, and rated for 19 A continuous drain current at T_A = 70°C. It serves as a high-efficiency synchronous rectifier and primary-side switch in notebook CPU VRMs and isolated DC-DC converters for networking infrastructure.

For engineers reviewing the IRFH7934TR2PBF datasheet, IRFH7934TR2PBF pinout, IRFH7934TR2PBF application, or IRFH7934TR2PBF equivalent, key selection criteria include low R_DS(on) at 4.5 V gate drive, fully characterized avalanche capability (E_AS = 97 mJ), low thermal resistance (R_θJA = 40 °C/W), and RoHS-compliant lead-free construction qualified to 260°C reflow.

Technical Context

This HEXFET power MOSFET employs Infineon's Trench technology to achieve ultra-low on-resistance and fast switching with minimal gate charge. Its optimized cell layout and large source lead reduce parasitic inductance and improve solder joint reliability under thermal cycling.

The device integrates a robust body diode with t_rr = 20–30 ns and Q_rr = 28–42 nC, enabling efficient operation in hard-switched synchronous buck topologies. Avalanche-rated design ensures ruggedness against inductive turn-off transients in unclamped inductive load conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum blocking voltage compatible with 24 V input bus and 12 V output rails in server VRMs.
R_DS(on) @ V_GS = 10 V	2.9 mΩ (typ) - Enables <1.5 W conduction loss at 24 A, critical for high-current CPU core rail efficiency.
Q_g	20 nC - Supports high-frequency switching (>1 MHz) with low gate drive power and reduced EMI.
t_r/t_f	16 ns / 7.5 ns - Fast edge rates minimize switching transition losses in sync-buck converters.
R_θJA	40 °C/W - Allows 19 A continuous operation at 70°C ambient without forced airflow in compact PCB layouts.
E_AS	97 mJ - Withstands single-pulse inductive energy up to 2.5 A × 15 V × 2.6 μs, ensuring system-level fault robustness.
V_SD	1.0 V (max) - Low body diode forward voltage reduces reverse recovery losses during dead-time conduction.

Pinout & Package

PQFN 5 mm × 6 mm package with exposed thermal pad (Option "E"), 8-pin configuration (3-source, 3-drain, 1-gate, 1-source sense), optimized for low-inductance high-current routing and enhanced thermal dissipation via bottom-side copper area.

Pin/Terminal	Circuit Role	Design Meaning
G	Gate	Control terminal accepting 0–10 V logic-level drive; low C_iss (3100 pF) minimizes Miller effect.
D1–D3	Drain	High-side switching node connection; paralleled pins reduce current density and package inductance.
S1–S3	Source	Power return path; multiple pins lower source loop inductance and improve stability in high-di/dt applications.
SS	Source Sense	Remote Kelvin sensing point for accurate gate drive referencing, reducing V_GS error due to source inductance.

Key Features

Feature	Design Value
Ultra-low R_DS(on) at 4.5 V	3.5 mΩ max - Enables direct compatibility with 5 V PWM controllers without level-shifting.
Low Q_gd/Q_g ratio	6.3 nC / 20 nC = 0.315 - Improves hard-switching immunity and reduces voltage overshoot during turn-off.
100% RG tested	1.7–3.1 Ω - Ensures consistent gate drive timing across production lots, critical for multi-phase current sharing.
Halogen-free & RoHS	Qualified to JEDEC J-STD-020 260°C reflow - Supports lead-free manufacturing without reliability compromise.
Large source lead	Enhanced mechanical anchoring - Reduces solder joint fatigue failure risk in thermally cycled server and telecom equipment.

Applications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRFH7107TRPBF	R_DS(on) = 4.2 mΩ @ 10 V; Q_g = 15 nC; same PQFN 5×6 mm package	Higher conduction loss but lower gate charge - better suited for higher-frequency, lower-current designs	Select when switching frequency exceeds 1.5 MHz and average current stays below 12 A.
SI7850DP-T1-GE3	R_DS(on) = 3.0 mΩ @ 10 V; Q_g = 22 nC; SO-8 package, no Kelvin source	Larger R_θJA (62 °C/W); no source sense pin - limits high-current phase-leg accuracy	Choose only for cost-sensitive, non-multiphase, ≤10 A applications where thermal margin is ample.

Compared with IRFH7934TR2PBF, IRFH7107TRPBF trades conduction efficiency for faster switching, while SI7850DP-T1-GE3 sacrifices thermal performance and sensing precision for legacy SO-8 compatibility-neither offers identical combination of low R_DS(on), low Q_g, Kelvin source, and 40 °C/W R_θJA.

FAQ

What is the maximum continuous drain current at 100°C ambient temperature?

At T_A = 100°C, derated by the linear derating factor of 0.025 W/°C from P_D = 3.1 W at 25°C, the maximum continuous drain current is approximately 12.5 A (based on R_DS(on) = 3.5 mΩ and thermal limit). This assumes adequate PCB copper area and no forced airflow.

Does IRFH7934TR2PBF support 4.5 V gate drive in production systems?

Yes - its R_DS(on) is specified at 4.5 V (3.5 mΩ max), and gate threshold voltage V_GS(th) ranges from 1.35 V to 2.35 V, ensuring full enhancement with standard 5 V logic drivers. No gate driver IC is required for most buck controller interfaces.

Is the PQFN 5×6 mm package compatible with standard reflow profiles?

Yes - it is qualified to JEDEC J-STD-020 for lead-free reflow up to 260°C peak temperature. The exposed thermal pad requires appropriate stencil design (≥70% paste coverage) and thermal via placement per IPC-7093 guidelines to ensure void-free solder joints.

How does the source sense (SS) pin improve system performance?

The SS pin provides a Kelvin connection to the source metallization, decoupling gate drive reference from high-di/dt source loop voltage drop. This prevents false turn-off during fast current transients and improves current-sharing accuracy in multi-phase VRMs by stabilizing effective V_GS.
