Product details

Overview

IPA80R450P7XKSA1 from Infineon is an 800V superjunction N-channel MOSFET in PG-TO220 FP package, featuring R_DS(on) = 0.45 Ω (max), Q_g = 24 nC (typ), V_GS(th) = 3 V (typ), and integrated ESD protection. It serves as a primary switch in hard/soft-switching flyback converters for LED lighting, low-power adapters, and auxiliary power supplies.

For engineers reviewing the IPA80R450P7XKSA1 datasheet, IPA80R450P7XKSA1 pinout, IPA80R450P7XKSA1 application, or IPA80R450P7XKSA1 equivalent, key selection criteria include 800V V_DS, 0.45 Ω R_DS(on), 24 nC gate charge, ±0.5 V V_GS(th) tolerance, and JEDEC industrial qualification.

Technical Context

This CoolMOS™ P7 device uses superjunction architecture optimized for high-voltage switching efficiency, with low E_oss (2.7 µJ @ 500 V) and reduced C_iss (770 pF) and C_oss (14 pF) enabling faster switching and lower losses in flyback and PFC topologies.

It integrates a body diode with t_rr = 1000 ns and Q_rr = 11 µC, and features a Zener-protected gate (ESD Class 2 HBM) plus dv/dt ruggedness of 100 V/ns, supporting robust operation in noisy industrial environments without external gate clamping.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	800 V - supports DC-link voltages up to 565 V RMS in universal-input offline applications
R_DS(on)	0.45 Ω max - enables low conduction loss at 11 A ID, critical for thermal management in compact adapters
Q_g	24 nC typ - reduces gate drive power and simplifies driver selection for 65–100 kHz flyback designs
V_GS(th)	3 V typ, ±0.5 V variation - ensures consistent turn-on across temperature and batch, improving production yield
E_oss	2.7 µJ @ 500 V - lowers switching loss during turn-off, directly improving efficiency in high-frequency flyback
T_j max	150 °C - rated for continuous operation in enclosed industrial and LED driver enclosures

Use Value: Low C_oss and high dv/dt ruggedness prevent false triggering during line-voltage transients in shared PCB layouts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STP80NF80	R_DS(on) = 0.08 Ω (lower), but V_DS = 800 V same; Q_g = 140 nC (5.8× higher); no integrated ESD diode	Better conduction loss but significantly higher switching loss and gate drive demand; requires external ESD protection	Select only when conduction loss dominates and gate drive capability permits high Q_g
IPP60R099P7	V_DS = 600 V (25% lower); R_DS(on) = 0.099 Ω; Q_g = 34 nC; same P7 process and ESD protection	Not suitable for 800 V applications; limited to 400 V DC-link systems like solar microinverters or 230 VAC-only designs	Choose only for cost-sensitive 600 V designs where 800 V margin is unnecessary

Compared with STP80NF80 and IPP60R099P7, IPA80R450P7XKSA1 uniquely balances 800 V rating, ultra-low E_oss, and integrated ESD protection-making it optimal for space-constrained, high-reliability flyback converters where gate drive simplicity and field robustness are prioritized over raw R_DS(on) minimization.

FAQ

What is the maximum continuous drain current for IPA80R450P7XKSA1 at 100°C case temperature?

The maximum continuous drain current is 7.1 A at T_C = 100 °C, as specified in Table 2 of the datasheet. This derating reflects thermal limits of the PG-TO220 FP package and ensures safe operation within its 4.4 °C/W junction-to-case thermal resistance. Operation above this current requires forced cooling or pulse-width limitation.

Does IPA80R450P7XKSA1 require an external gate resistor for stability in flyback applications?

Yes-a gate resistor (typically 5–15 Ω) is recommended to dampen ringing and control dV/dt during switching transitions. While the device's low Q_g and internal Zener improve robustness, external RG remains essential to manage EMI, prevent oscillation with PCB trace inductance, and ensure reliable zero-voltage switching in QR controllers.

Can IPA80R450P7XKSA1 be used in parallel configurations?

Yes-it is explicitly optimized for paralleling due to tight V_GS(th) distribution (±0.5 V) and matched dynamic parameters. However, Infineon recommends using ferrite beads on each gate line or individual totem-pole drivers to suppress cross-talk and ensure balanced current sharing, especially above two devices.

Is the drain-source body diode suitable for synchronous rectification in secondary-side applications?

No-the integrated body diode has t_rr = 1000 ns and Q_rr = 11 µC, making it unsuitable for synchronous rectification where fast recovery (<100 ns) and low Q_rr are mandatory. It is designed for freewheeling in primary-side switching only; external Schottky or GaN FETs are required for secondary-side SR.
