Product details
Overview
IPD90R1K2C3ATMA1 from Infineon Technologies is a 900 V, 1.2 Ω RDS(on) CoolMOS™ C3 superjunction power MOSFET in PG-TO252 (DPAK) package, optimized for quasi-resonant flyback and forward SMPS topologies in PC silverbox and industrial power supplies. It delivers 2.8 A continuous drain current at TC = 25 °C, 28 nC total gate charge, and extreme dv/dt ruggedness up to 4 V/ns.
For engineers reviewing the IPD90R1K2C3ATMA1 datasheet, IPD90R1K2C3ATMA1 pinout, IPD90R1K2C3ATMA1 application, or IPD90R1K2C3ATMA1 equivalent, key selection criteria include its 900 V breakdown voltage, ultra-low RDS(on) × Qg figure-of-merit, JEDEC-qualified reliability for industrial SMPS, and integrated fast-recovery body diode with 310 ns trr and 3.7 µC Qrr.
Technical Context
This CoolMOS™ C3 device employs superjunction technology to achieve high-voltage blocking with low conduction loss. Its 1.2 Ω RDS(on) at 25 °C and 2.5 Ω at 150 °C enables efficient operation across wide temperature ranges in offline converters.
The MOSFET features enhanced avalanche ruggedness (68 mJ single-pulse EAS) and reverse diode dv/dt immunity (4 V/ns), supporting robust operation in hard-switched and resonant topologies where voltage transients and commutation stress are critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 900 V superjunction MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IPW90R1K2C3FKSA1 | TO-220FP package; identical RDS(on), Qg, and VBR(DSS); higher RthJC (2.0 K/W). | Requires larger heatsink footprint; better suited for through-hole industrial designs with forced air. | Select when mechanical mounting constraints favor TO-220FP or when higher thermal mass is needed for intermittent duty cycles. |
| STP90NF03L | 30 V device; incompatible voltage rating; not a functional substitute for 900 V operation. | N/A - Not suitable for any application requiring >400 V DC-link capability. | Avoid entirely; mismatched voltage class renders it unsafe for intended use cases. |
Compared with IPW90R1K2C3FKSA1, IPD90R1K2C3ATMA1 offers superior thermal resistance (1.5 vs. 2.0 K/W) and smaller footprint for space-constrained PCBs, while STP90NF03L fails basic voltage qualification and must be excluded from 900 V designs.

FAQ
What is the maximum continuous drain current for IPD90R1K2C3ATMA1 at 100 °C case temperature?
The maximum continuous drain current is 3.2 A at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits of the PG-TO252 package and ensures safe operation within the SOA boundary at elevated ambient temperatures typical in enclosed power supplies.
Does IPD90R1K2C3ATMA1 have an integrated body diode, and what are its key recovery parameters?
Yes, it includes a monolithically integrated fast-recovery body diode. Key parameters are reverse recovery time trr = 310 ns, reverse recovery charge Qrr = 3.7 µC, and peak reverse recovery current Irrm = 19 A, measured at VR = 400 V, IF = IS, and diF/dt = 100 A/µs. These values enable low-loss commutation in QR and LLC topologies.
Is IPD90R1K2C3ATMA1 halogen-free and RoHS compliant?
Yes, the "AT" suffix denotes halogen-free mold compound and Pb-free lead plating. It complies fully with RoHS Directive 2011/65/EU and meets IEC 61249-2-21 for halogen content, making it suitable for environmentally regulated industrial and computing equipment.
What is the gate threshold voltage range, and how does it affect drive circuit design?
VGS(th) is specified as 2.5–3.5 V at TJ = 25 °C. This relatively low and narrow threshold supports clean turn-on with standard 5 V or 10 V gate drivers, but requires careful noise immunity design-especially in high-dv/dt environments-to avoid spurious conduction. A minimum 10 V drive is recommended for full enhancement.
