At 600 mOhm max, the on-resistance is on the higher side for a 650 V rated FET, but the low 23 nC gate charge compensates in frequency-sensitive designs. For a 100 kHz PFC stage, the switching losses from Qg dominate over conduction losses at light load; this part shifts the balance toward lower switching loss, which is why it fits auxiliary supplies and lower-power (< 150 W) SMPS where the inductor current is moderate.

Frequently asked questions
What is the replacement for IPP65R600E6?
No official replacement has been announced because the part remains active. For a pin-compatible alternative within the same CoolMOS™ family, consider the IPP65R600E6 itself — Infineon has not designated a successor. If a second source is needed, verify pin-compatibility with a part like the STMicroelectronics STP7NK65Z, but confirm the gate charge and Rds(on) match your switching frequency and load.
What is the closest pin-compatible alternative to IPP65R600E6 in this component family?
Within the Infineon CoolMOS™ 600E6 series, the IPP65R600E6 is the standard 600 mOhm variant. A higher-current sibling like the IPP65R380E6 (380 mOhm) is pin-compatible in the same TO-220-3 footprint but has a higher gate charge. For a direct electrical match, stay with the IPP65R600E6 or cross to a competitor's 600 mOhm, 650 V TO-220 N-channel FET, verifying Qg and Vgs(th) thresholds.
