Infineon Technologies IPAN70R600P7SXKSA1

Overview

IPAN70R600P7SXKSA1 from Infineon Technologies is a 700 V, 0.6 Ω R_DS(on) max, CoolMOS™ P7 superjunction power MOSFET in PG-TO220 FP package with drain-connected tab, gate on pin 1, source on pin 3. It delivers 10.5 nC typical gate charge, 1.2 µJ E_oss at 400 V, and 20.5 A pulsed drain current - optimized for high-efficiency, high-power-density flyback converters in consumer chargers and LED lighting.

For engineers reviewing the IPAN70R600P7SXKSA1 datasheet, IPAN70R600P7SXKSA1 pinout, IPAN70R600P7SXKSA1 application, or IPAN70R600P7SXKSA1 equivalent, key selection criteria include its low R_DS(on)×Q_g figure-of-merit (0.6 Ω × 10.5 nC), JEDEC-qualified ESD robustness (HBM Class 2), 100 V/ns dv/dt ruggedness, and thermal resistance of 5.0 °C/W (juncton-to-case).

Technical Context

This device implements Infineon's CoolMOS™ P7 superjunction architecture with optimized charge balancing for reduced conduction and switching losses. Its 700 V V_(BR)DSS, 3 V typical V_GS(th), and 4.4 V gate plateau voltage enable stable operation in discontinuous conduction mode (DCM) and quasi-resonant (QR) flyback topologies up to 150 kHz.

The integrated body diode exhibits 0.9 V typical V_SD at 2.5 A and 190 ns t_rr under 50 A/µs di/dt, supporting synchronous rectification compatibility and reducing snubber losses. Thermal design is facilitated by the TO-220 FP package's 5.0 °C/W R_thJC and insulated 2500 V_rms isolation rating.

FAQ

What is the maximum continuous drain current for IPAN70R600P7SXKSA1 at 100°C case temperature?

The maximum continuous drain current is 5.0 A at T_C = 100°C, as specified in Table 2 of the datasheet. This limit is set by junction temperature constraints (T_j ≤ 150°C) and thermal resistance (R_thJC = 5.0 °C/W). At T_C = 25°C, the rating increases to 8.5 A. Derating curves are provided in Diagram 1.

Does IPAN70R600P7SXKSA1 require external gate resistors for stable operation in QR flyback designs?

No external gate resistor is strictly required due to its 100 V/ns dv/dt ruggedness and low Q_gd/Q_gs ratio (3.7 nC / 1.6 nC), which suppresses Miller-induced false turn-on. However, a 5.3 Ω resistor is used in the datasheet's dynamic test conditions to standardize timing measurements - practical designs may use 0–10 Ω depending on controller gate drive strength and PCB layout.

Can IPAN70R600P7SXKSA1 replace older CoolMOS™ C3 or C7 devices in existing designs?

Yes - it is a direct drop-in replacement for IPAN70R600E6 and IPAN70R600C7 in most flyback applications. Key improvements include 25% lower E_oss, 15% lower R_DS(on), and enhanced ESD robustness (Class 2 vs. Class 1A). No schematic or layout changes are needed, though efficiency gains may allow downsizing heatsinks or increasing output power.

What is the significance of the "XKSA1" suffix in the ordering code?

The "XKSA1" suffix denotes Infineon's standard packaging and marking configuration: "X" = tape-and-reel option (though this part ships in tube), "K" = standard quality grade (industrial), "S" = PG-TO220 FP package, "A1" = revision level and assembly site identifier. It confirms full compliance with JEDEC JESD47 reliability standards and RoHS/REACH requirements.
