Product details

Overview

IPI90R1K0C3XKSA1 from Infineon Technologies is a 900 V, 1.0 Ω (max) R_DS(on) CoolMOS™ superjunction power MOSFET in PG-TO262 package, optimized for quasi-resonant flyback and forward SMPS topologies. It delivers 3.3 A continuous drain current at T_C = 25 °C, 34 nC typical gate charge, and extreme dv/dt ruggedness up to 4 V/ns for robust operation in high-frequency industrial and consumer power supplies.

For engineers reviewing the IPI90R1K0C3XKSA1 datasheet, IPI90R1K0C3XKSA1 pinout, IPI90R1K0C3XKSA1 application, or IPI90R1K0C3XKSA1 equivalent, key selection criteria include its 900 V breakdown voltage, ultra-low Q_g-R_DS(on) figure-of-merit, JEDEC-qualified reliability, and reverse diode recovery performance (t_rr = 340 ns, Q_rr = 4.1 µC) in hard-switched and resonant converters.

Technical Context

This CoolMOS™ device employs superjunction cell architecture enabling high-voltage blocking with low on-resistance. Its gate threshold voltage (2.5–3.5 V) and plateau voltage (4.6 V) support standard 10 V gate drive while maintaining noise immunity. The integrated body diode features soft reverse recovery characteristics critical for ZVS/ZCS operation.

Thermal design is supported by a junction-to-case thermal resistance of 1.4 K/W and a maximum operating junction temperature of 150 °C. Dynamic parameters-including C_iss = 850 pF, C_oss = 42 pF, and t_d(off) = 400 ns-are specified under standardized 400 V, 3.3 A switching conditions with 62.4 Ω gate resistor.

Key Specifications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IPW90R1K2C3FKSA1	Same 900 V rating, but R_DS(on) = 1.2 Ω (max), Q_g = 28 nC; PG-TO247 package	Higher conduction loss, lower gate drive loss; larger footprint and higher thermal resistance (R_thJC = 0.8 K/W)	Prefer when gate drive power is limiting and board space allows TO247 mounting
STP9NK90ZFP	Zener-protected 900 V MOSFET, R_DS(on) = 1.2 Ω (max), Q_g = 45 nC; TO-220FP package	No avalanche rating, higher Q_g, no soft diode; lacks JEDEC qualification for industrial use	Acceptable only in cost-sensitive, non-critical consumer adapters with tight BOM constraints

Compared with IPW90R1K2C3FKSA1 and STP9NK90ZFP, the IPI90R1K0C3XKSA1 offers superior R_DS(on) × Q_g FoM and JEDEC-qualified ruggedness in a compact TO262 form factor-making it optimal for space-constrained, high-efficiency industrial and computing power supplies where reliability and thermal performance are prioritized.

FAQ

What is the maximum continuous drain current for IPI90R1K0C3XKSA1 at 100 °C case temperature?

The maximum continuous drain current is 3.6 A at T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the PG-TO262 package and ensures safe operation within the 150 °C maximum junction temperature limit under real-world heatsinking conditions.

Does IPI90R1K0C3XKSA1 have an integrated avalanche-rated body diode?

No-the body diode is not avalanche-rated. However, the device is qualified for repetitive unclamped inductive switching (UIS) with E_AR = 50 mJ and single-pulse avalanche energy E_AS = 97 mJ at I_D = 1.1 A and V_DD = 50 V, enabling limited energy absorption during transient events.

Can IPI90R1K0C3XKSA1 be used with 5 V gate drive?

It is not recommended. The gate threshold voltage range is 2.5–3.5 V, but full enhancement requires ≥10 V to achieve rated R_DS(on) ≤ 1.0 Ω. At 5 V, R_DS(on) increases significantly-exceeding 3 Ω-leading to excessive conduction loss and thermal runaway risk in continuous operation.

Is the PG-TO262 package lead-free and RoHS compliant?

Yes. The IPI90R1K0C3XKSA1 uses Pb-free lead plating and complies with RoHS Directive 2011/65/EU. The device is also qualified per J-STD-020 moisture sensitivity level (MSL) 1, allowing unlimited floor life at ≤30 °C/60% RH without baking prior to soldering.
