Infineon Technologies IPS06N03LA G

Overview

IPS06N03LA G from Infineon Technologies is an N-channel logic-level power MOSFET in PG-TO251-3-11 package, rated for 25 V V_DS, 50 A continuous drain current at T_C = 100 °C, and 5.7 mΩ max R_DS(on) (SMD version), optimized for high-frequency DC/DC converters in server VRMs and POL modules.

For engineers reviewing the IPS06N03LA G datasheet, IPS06N03LA G pinout, IPS06N03LA G application, or IPS06N03LA G equivalent, key selection criteria include gate charge × R_DS(on) figure of merit, 175 °C junction rating, thermal resistance (R_thJC = 1.8 K/W), reverse diode dv/dt capability (6 kV/µs), and SMD-compatible TO-251 footprint.

Technical Context

This device implements a trench-based OptiMOS®2 silicon process enabling low gate charge (Q_g = 17–22 nC) and low R_DS(on) with logic-level gate drive compatibility (V_GS(th) = 1.2–2.0 V). It supports synchronous rectification in buck converters due to its low Q_gd (4.6–6.9 nC) and fast switching (t_r = 7.2–11 ns, t_f = 4.6–6.9 ns).

The integrated body diode exhibits low forward voltage (V_SD = 0.92–1.2 V @ I_F = 50 A, T_j = 25 °C) and low reverse recovery charge (Q_rr = 10 nC), reducing switching losses in hard-commutated topologies. Thermal design is enabled by R_thJC = 1.8 K/W and operation up to 175 °C.

Key Specifications

Pinout & Package

IPS06N03LA G uses the PG-TO251-3-11 package - a surface-mount variant of the standard TO-251 (IPAK) with gull-wing leads and exposed drain pad for thermal enhancement. The package is RoHS-compliant and features Pb-free lead plating.

FAQ

Is IPS06N03LA G suitable for synchronous rectification in a 1 MHz buck converter?

Yes. With Q_g = 17–22 nC, Q_gd = 4.6–6.9 nC, and R_DS(on) = 4.8–5.7 mΩ (SMD), it delivers low switching and conduction losses at 1 MHz. Its 6 kV/µs dv/dt rating and low Q_rr (10 nC) further ensure reliable synchronous operation without shoot-through risk.

What is the recommended PCB layout for thermal performance?

Mount the exposed drain pad directly to ≥6 cm² of 70 µm thick copper on an FR4 PCB (40 mm × 40 mm), using multiple thermal vias to inner ground planes. Maintain ≥0.5 mm clearance between gate trace and high-dI/dt paths to minimize coupling. Avoid solder mask over the drain pad.

Does IPS06N03LA G require a gate resistor for stability?

Yes. A 2.2–10 Ω series gate resistor is recommended to dampen ringing caused by gate loop inductance and MOSFET input capacitance (C_iss = 2093–2653 pF). Values depend on driver strength and layout; lower values increase switching speed but risk overshoot.

Can IPS06N03LA G replace IPS06N03L G in existing designs?

No. IPS06N03L G is a non-RoHS, leaded version with different plating and JEDEC qualification status. While electrically identical, the G suffix denotes Pb-free, RoHS-compliant construction with modified reflow profile requirements - mixing versions may cause solder joint reliability issues or compliance failures.
