Infineon Technologies IPU80R2K0P7AKMA1

Overview

IPU80R2K0P7AKMA1 from Infineon is an 800V superjunction N-channel CoolMOS™ P7 power MOSFET in PG-TO251-3 (IPAK) package, featuring R_DS(on) = 2.0 Ω (max), Q_g = 9 nC (typ), V_GS(th) = 3 V (typ), integrated Zener ESD protection, and JEDEC-qualified industrial reliability. It serves as a high-voltage switching element in flyback and PFC stages for LED lighting, low-power adapters, and solar auxiliary supplies.

For engineers reviewing the IPU80R2K0P7AKMA1 datasheet, IPU80R2K0P7AKMA1 pinout, IPU80R2K0P7AKMA1 application, or IPU80R2K0P7AKMA1 equivalent, key selection criteria include its 800V V_DS, 3V gate threshold with ±0.5V variation, 0.85 µJ E_oss at 500V, 5.1 °C/W R_thJC, and suitability for hard/soft-switching topologies requiring robust dv/dt ruggedness (100 V/ns).

Technical Context

This device implements Infineon's 4th-generation superjunction architecture optimized for 800V operation, delivering best-in-class figure-of-merit (R_DS(on) × E_oss) and reduced C_iss (175 pF) and C_oss (4.0 pF). Its 3V V_GS(th) enables direct drive from 3.3V/5V controllers without level-shifting.

The integrated Zener diode provides HBM Class 1C ESD protection, and its 100 V/ns dv/dt ruggedness supports reliable operation in high-noise flyback and PFC circuits. Thermal design is facilitated by low R_thJC (5.1 °C/W) and validated SOA up to 10 ms at T_C = 80°C.

FAQ

What is the maximum continuous drain current for IPU80R2K0P7AKMA1 at 100°C case temperature?

The maximum continuous drain current is 1.9 A at T_C = 100°C, as specified in Table 2 of the datasheet. This value is thermally limited by the 150°C maximum junction temperature and the 5.1 °C/W R_thJC. Derating curves in Diagram 1 confirm usable power dissipation drops to ~12 W at T_C = 100°C.

Does IPU80R2K0P7AKMA1 require an external gate resistor for stable operation in flyback converters?

While not strictly required due to its low Q_g (9 nC) and internal R_G (4.0 Ω), a small external gate resistor (typically 5–15 Ω) is recommended to dampen ringing and control dV/dt during turn-on/off. Infineon's application note AN2019-04 confirms this practice improves EMI and reduces overshoot in 65 kHz flyback designs.

Can IPU80R2K0P7AKMA1 be used in parallel configurations?

Yes-its tight V_GS(th) tolerance (±0.5 V) and positive R_DS(on) temperature coefficient support stable current sharing. Infineon recommends using individual gate resistors (≥10 Ω) and, for high-reliability systems, adding ferrite beads on each gate line to suppress common-mode oscillation, as noted in the "MOSFET paralleling" footnote.

Is the drain tab electrically isolated from the package leads?

No-the drain tab is internally connected to Pin 2 (Drain) and is not electrically isolated. It must be mounted to a heatsink or thermal pad that is either floating or referenced to the drain potential. Insulating pads or coatings are required if mounting to a grounded heatsink, as confirmed in Package Outline drawing PG-TO251-3 in Appendix A.
