Product details

Overview

IPA95R750P7XKSA1 from Infineon is a 950V superjunction N-channel MOSFET in PG-TO220 FP package, featuring R_DS(on) = 0.75 Ω (max), Q_g = 23 nC (typ), V_GS(th) = 3 V (typ), integrated ESD protection, and internal body diode. It is engineered for high-voltage flyback converters in LED lighting, smart meters, and auxiliary power supplies.

For engineers reviewing the IPA95R750P7XKSA1 datasheet, IPA95R750P7XKSA1 pinout, IPA95R750P7XKSA1 application, or IPA95R750P7XKSA1 equivalent, key selection criteria include 950V V_DS rating, low E_oss (1.9 µJ @ 500V), tight V_GS(th) tolerance (±0.5V), gate drive compatibility at 3V threshold, and industrial JEDEC qualification.

Technical Context

This CoolMOS™ P7 device employs charge compensation technology to achieve best-in-class R_DS(on) × E_oss figure-of-merit and reduced C_iss (712 pF) and C_oss (11 pF). Its 3V gate threshold with ±0.5V variation enables reliable turn-on under wide supply conditions and simplifies gate driver design.

The MOSFET integrates a Zener-protected gate structure for HBM Class 2 ESD robustness and features an optimized internal body diode with t_rr = 684 ns and Q_rr = 5 µC-critical for reducing switching losses in discontinuous conduction mode (DCM) flyback topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	950 V - supports primary-side operation in universal-input offline flyback converters up to 400 VAC mains with margin.
R_DS(on), max	0.75 Ω @ T_j = 25°C - determines conduction loss and thermal rise in 9 A continuous drain applications.
Q_g, typ	23 nC - defines gate drive energy requirement and influences switching speed and driver IC selection.
E_oss	1.9 µJ @ 500 V - quantifies output capacitance energy loss during hard-switched turn-on, directly impacting efficiency at 65–100 kHz.
V_GS(th), typ	3 V - enables direct interface with 3.3 V or 5 V logic-level controllers without level-shifting.
t_rr	684 ns - limits reverse recovery-related voltage overshoot and ringing when used with transformer leakage inductance.
R_thJC	4.4 °C/W - defines junction-to-case thermal resistance, enabling heatsink sizing for 28 W P_tot at T_C = 25°C.

Pinout & Package

IPA95R750P7XKSA1 is housed in PG-TO220 FP (FullPAK) package with isolated mounting screw hole and drain-connected tab. Pin 1 = Gate, Pin 2 = Drain (tab), Pin 3 = Source.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control electrode	Receives gate drive signal; low input capacitance (C_iss = 712 pF) reduces driver loading.
Pin 2 (Drain)	High-voltage power terminal	Connected to transformer primary and heatsink; electrically isolated case enables direct mounting without insulator.
Pin 3 (Source)	Reference node for gate drive	Serves as return path for gate current and sense point for current-mode control feedback.

Key Features

Feature	Design Value
Best-in-class R_DS(on) × E_oss	Enables >90% efficiency in 30–60 W flyback designs while maintaining low gate drive loss.
V_GS(th) = 3 V ± 0.5 V	Ensures consistent turn-on across temperature and process variation, reducing need for overdrive margin.
Integrated Zener ESD protection (HBM Class 2)	Eliminates external gate protection components and improves manufacturing yield in automated assembly.
Optimized body diode (t_rr = 684 ns, Q_rr = 5 µC)	Reduces snubber losses and EMI in DCM flyback, supporting higher switching frequencies without derating.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPW95R1K2P7	R_DS(on) = 1.2 Ω (higher), Q_g = 15 nC (lower), same 950 V rating	Better suited for lower-current, higher-efficiency light-load operation due to lower gate charge	Select when optimizing for no-load power and gate drive simplicity over peak power density.
STP95N95F7	R_DS(on) = 0.78 Ω, Q_g = 26 nC, no integrated ESD diode	Requires external gate protection; slightly higher switching loss at 100 kHz	Choose only if cost sensitivity outweighs ESD robustness and thermal margin requirements.

Compared with IPW95R1K2P7 and STP95N95F7, IPA95R750P7XKSA1 delivers the lowest R_DS(on) × E_oss product in its class, enabling highest power density in space-constrained flyback designs while maintaining superior production yield through integrated ESD protection.

FAQ

What is the maximum continuous drain current for IPA95R750P7XKSA1 at 100°C case temperature?

The maximum continuous drain current is 5.5 A at T_C = 100°C, as specified in Table 2 of the datasheet. This rating reflects thermal limitation-not silicon current capability-and assumes proper heatsinking to maintain case temperature at or below 100°C under steady-state operation.

Does IPA95R750P7XKSA1 require a gate resistor for paralleling, and if so, what value is recommended?

Yes-Infineon recommends using individual ferrite beads or separate totem-pole drivers on each gate when paralleling multiple IPA95R750P7XKSA1 devices. A discrete gate resistor alone is insufficient; the goal is to suppress high-frequency oscillation between paralleled units, not merely limit peak current.

Can IPA95R750P7XKSA1 be used in continuous conduction mode (CCM) PFC boost stages?

No-it is not recommended for CCM PFC. The device's body diode recovery characteristics (t_rr = 684 ns, Q_rr = 5 µC) are optimized for DCM flyback, not hard-commutated boost diodes. For 950 V PFC, Infineon specifies dedicated P7 variants like IPA95R1K2P7 with enhanced diode softness.

Is the PG-TO220 FP package of IPA95R750P7XKSA1 electrically insulated from the drain terminal?

No-the drain is internally connected to the metal tab, which serves as both the drain terminal and mechanical mounting surface. The "FP" (FullPAK) variant provides creepage/clearance isolation but does not insulate the tab; an isolating pad or shoulder washer must be used when mounting to a grounded heatsink.
