Product details

Overview

IPI90R340C3XKSA1 from Infineon Technologies is a 900 V, 0.34 Ω (max) CoolMOS™ C3 superjunction power MOSFET in PG-TO262 (I2PAK) package, optimized for high-efficiency quasi-resonant flyback and forward SMPS topologies. It delivers ultra-low gate charge (94 nC typ), extreme dv/dt ruggedness (50 V/ns), and high peak current capability (34 A pulsed), enabling compact, reliable power supplies for PC silverbox and industrial SMPS applications.

For engineers reviewing the IPI90R340C3XKSA1 datasheet, IPI90R340C3XKSA1 pinout, IPI90R340C3XKSA1 application, or IPI90R340C3XKSA1 equivalent, key selection criteria include R_DS(on) at 150 °C (0.76 Ω max), E_AS (678 mJ), Q_g (94 nC), diode reverse recovery charge (Q_rr = 11 µC), and thermal resistance R_thJC (0.6 K/W).

Technical Context

This CoolMOS™ C3 device employs charge compensation technology to achieve best-in-class R_DS(on) × Q_g figure-of-merit for 900 V MOSFETs. Its optimized cell structure enables low output capacitance (C_oss = 120 pF) and energy-related C_o(er) = 71 pF, reducing switching losses in hard- and soft-switching converters.

The integrated fast-recovery body diode features t_rr = 510 ns and I_rrm = 41 A, supporting ZVS operation in QR flyback designs. Rated for repetitive avalanche (E_AR) and qualified per JEDEC J-STD-20/JESD22, it supports robust operation under transient overvoltage and short-circuit conditions.

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
IPW90R340C3FKSA1	Same die, TO-247-3 package; higher R_thJC (0.45 K/W) but larger creepage/clearance	Better suited for higher-power (>500 W) industrial SMPS requiring enhanced thermal headroom	Select when board space allows TO-247 and thermal budget exceeds 120 W
STP90NF03L	30 V logic-level N-channel; R_DS(on) = 3.3 mΩ, no avalanche rating, not 900 V rated	Only viable in low-voltage (<60 V) DC-DC converters - not a functional substitute	Avoid for any off-line AC-DC application; incompatible voltage class

Compared with IPW90R340C3FKSA1, the IPI90R340C3XKSA1 offers identical electrical specs in a more compact, cost-effective TO262 package with slightly higher R_thJC; STP90NF03L is electrically and functionally incompatible due to its 30 V rating and absence of high-voltage ruggedness features.

FAQ

What is the maximum continuous drain current at T_C = 100 °C?

The maximum continuous drain current I_D is 9.5 A at case temperature T_C = 100 °C, as specified in the Absolute Maximum Ratings table. This value accounts for thermal derating and ensures safe operation within the SOA boundary when mounted on a heatsink with appropriate thermal interface.

Does IPI90R340C3XKSA1 have an integrated body diode, and what are its key parameters?

Yes, it includes a monolithic fast-recovery body diode with V_SD = 0.8–1.2 V at I_F = 9.2 A and T_J = 25 °C, t_rr = 510 ns, Q_rr = 11 µC, and I_rrm = 41 A. These values enable efficient operation in quasi-resonant topologies where diode conduction occurs during dead time.

Can this MOSFET be used in a synchronous rectification configuration?

No - IPI90R340C3XKSA1 is a unidirectional high-side or low-side switch, not designed for synchronous rectification. Its body diode is optimized for clamping and recovery, not bidirectional conduction. Synchronous rectification requires dedicated SR controllers and logic-level MOSFETs with matched R_DS(on) and low gate threshold.

What is the recommended gate resistor value for typical QR flyback operation?

A gate resistor of 23.1 Ω is used in the datasheet's dynamic test condition (V_DD = 400 V, I_D = 9.2 A), yielding measured t_d(on) = 70 ns and t_f = 25 ns. For most QR flyback designs, 15–33 Ω balances switching speed, EMI, and gate driver stress - adjust based on observed ringing and thermal performance.
