Product details

Overview

IPB25N06S3-25 from Infineon Technologies is an N-channel enhancement-mode automotive-grade power MOSFET in PG-TO263-3-2 package, rated for 55 V V_DS, 25 A continuous drain current at T_C = 25 °C, and 24.8 mΩ max R_DS(on) (SMD version). It operates up to 175 °C junction temperature, is AEC-Q101 qualified, and 100% avalanche tested-used in high-reliability DC-DC converters and motor control stages.

For engineers reviewing the IPB25N06S3-25 datasheet, IPB25N06S3-25 pinout, IPB25N06S3-25 application, or IPB25N06S3-25 equivalent, key selection criteria include its 3.3 K/W R_thJC, 27–41 nC total gate charge, 120 mJ single-pulse avalanche energy, and integrated body diode with 15 ns t_rr and 0.9 V typical V_SD at 25 A.

Technical Context

This OptiMOS™-T2 device uses trench-gate superjunction technology optimized for low conduction and switching losses in 12 V/24 V automotive and industrial power stages. Its gate threshold voltage (2.1–4.0 V) enables robust TTL/CMOS-level drive compatibility, while the 7.0 V gate plateau supports stable Miller region control during hard-switching.

The MOSFET integrates a fast, soft-recovery body diode (t_rr = 15 ns, Q_rr = 15 nC) and exhibits low output capacitance (C_oss = 283 pF) and reverse transfer capacitance (C_rss = 270 pF), enabling high-frequency operation up to 500 kHz in synchronous buck topologies.

FAQ

What is the maximum allowable gate-source voltage for IPB25N06S3-25?

The absolute maximum gate-source voltage is ±20 V, qualified at –5 V and +20 V per datasheet Rev. 1.1. Operation beyond this range risks permanent oxide damage. Recommended drive is 10 V for full enhancement, with 7.0 V gate plateau ensuring stable Miller inversion during switching.

Is IPB25N06S3-25 suitable for synchronous rectification in a 48 V input buck converter?

Yes-it supports synchronous rectification up to ~200 kHz due to its 27 ns rise/fall times, 27–41 nC Q_g, and 15 ns body diode t_rr. However, at 48 V input, ensure V_DS derating (55 V rating provides only 7 V margin); consider higher-V_DS variants for long-term reliability.

Does IPB25N06S3-25 require a gate resistor for safe operation?

A gate resistor is required to control dV/dt and suppress oscillation. Typical values range from 5 Ω to 22 Ω depending on driver strength and layout parasitics. The 14.8 Ω R_G used in datasheet switching characterization yields 27 ns t_r/t_f and balances EMI vs. switching loss.

How does the thermal resistance of IPB25N06S3-25 compare between PCB and heatsink mounting?

R_thJC is fixed at 3.3 K/W regardless of mounting method. R_thJA drops from 62 K/W (minimal footprint) to 40 K/W with 6 cm² copper cooling area. Heatsink mounting is not supported-the PG-TO263-3-2 package is designed for direct PCB thermal relief, not mechanical heatsink attachment.
