Infineon Technologies IPI70R950CEXKSA1

Overview

IPI70R950CEXKSA1 from Infineon Technologies is a 700 V, 950 mΩ superjunction MOSFET in PG-TO262 (I²PAK) package, optimized for high-efficiency, cost-sensitive offline SMPS in lighting and adapter applications. It delivers 7.4 A continuous drain current at T_C = 25°C, 15.3 nC total gate charge, and 1.5 µJ output switching energy at 400 V, enabling compact, thermally robust flyback and PFC stages.

For engineers reviewing the IPI70R950CEXKSA1 datasheet, IPI70R950CEXKSA1 pinout, IPI70R950CEXKSA1 application, or IPI70R950CEXKSA1 equivalent, key selection criteria include R_DS(on) vs. temperature stability, E_oss-driven hard-switching efficiency, commutation ruggedness (50 V/ns dv/dt), and TO-262 thermal resistance (1.85 °C/W).

Technical Context

This CoolMOS™ CE device implements a charge-compensated superjunction structure with optimized cell pitch and epitaxial doping to achieve low R_DS(on) × Q_g figure-of-merit (FOM) of 14.5 Ω·nC. Its gate threshold voltage (2.5–3.5 V) and plateau voltage (5.4 V) support standard 10–13 V gate drivers without level-shifting.

The integrated body diode exhibits 226 ns reverse recovery time and 1.3 µC Q_rr at 400 V, enabling reliable operation in discontinuous conduction mode (DCM) flybacks. Thermal design is anchored by 1.85 °C/W junction-to-case resistance and 62 °C/W junction-to-ambient rating under leaded conditions.

FAQ

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

The IPI70R950CEXKSA1 supports 4.7 A continuous drain current at T_C = 100°C, as specified in Table 2 of the Rev. 2.0 datasheet. This derating reflects thermal limits of the TO-262 package and ensures safe operation within the 150°C maximum junction temperature under sustained load.

Does this MOSFET require a negative gate turn-off voltage?

No. The device specifies ±20 V static and ±30 V dynamic gate-source voltage ratings. Standard 0 V to +12 V gate drive is sufficient; negative turn-off is not required due to its 3.0 V typical threshold voltage and stable gate oxide design.

Can it replace older CoolMOS™ C6 or C7 devices in existing designs?

Yes, with validation. While pin-compatible and sharing similar V_DS and R_DS(on), the CE generation has lower Q_g and E_oss than C6/C7. Gate drive timing and snubber values may need adjustment to exploit improved switching performance without oscillation.

Is the drain tab electrically isolated from the package outline?

Yes. The PG-TO262 package features an isolated drain tab, confirmed in the "Package Outlines" section (page 12) of the datasheet. This enables direct heatsink mounting with standard insulating pads while maintaining functional isolation between drain and mounting surface.
