Product details
Overview
IPD90R1K2C3BTMA1 from Infineon Technologies is a 900 V, 1.2 Ω RDS(on) CoolMOS™ C3 superjunction power MOSFET in PG-TO252 (DPAK) package, optimized for high-efficiency 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 IPD90R1K2C3BTMA1 datasheet, IPD90R1K2C3BTMA1 pinout, IPD90R1K2C3BTMA1 application, or IPD90R1K2C3BTMA1 equivalent, key selection criteria include its 900 V breakdown voltage, low RDS(on) × Qg figure-of-merit, avalanche-rated operation, JEDEC-qualified reliability, and halogen-free packaging compliance.
Technical Context
This device employs CoolMOS™ C3 technology with optimized charge compensation structure to reduce conduction and switching losses simultaneously. Its 1.2 Ω max RDS(on) at 25 °C and 2.5 Ω at 150 °C enables stable operation across wide temperature ranges in high-voltage offline converters.
The MOSFET features ultra-low gate charge (Qg = 28 nC typ), low output capacitance (Coss = 35 pF), and energy-related effective output capacitance (Co(er) = 23 pF), supporting high-frequency ZVS/ZCS soft-switching in QR flyback designs up to 100 kHz.
Key Specifications

Pinout & Package
IPD90R1K2C3BTMA1 is housed in PG-TO252 (DPAK) package with standard 3-pin configuration: Drain (tab), Source (pin 1), Gate (pin 2). The exposed drain tab provides low thermal resistance path to PCB copper pour.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main high-side current path | Electrically connected to PCB copper pour for thermal dissipation and low-inductance return path. |
| Source (Pin 1) | Reference node for gate drive and current sensing | Low-impedance connection to source ground plane; critical for stable gate control and accurate current monitoring. |
| Gate (Pin 2) | Control terminal for channel modulation | Requires low-impedance gate driver (<1.3 Ω internal RG) to minimize switching losses and ringing. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(on) × Qg | Minimizes combined conduction + switching loss, enabling >92% efficiency in 65–100 W QR flyback designs. |
| JEDEC-qualified reliability | Validated per J-STD-20/JESD22 for industrial and consumer SMPS lifetime requirements. |
| Halogen-free mold compound | Complies with RoHS and IPC-1752A environmental standards; no brominated flame retardants. |
| High peak current capability | Supports ID,pulse = 10 A for short-duration overload conditions without thermal runaway. |
| Reverse diode with low Qrr | Qrr = 3.7 µC enables reduced diode recovery loss in synchronous rectification or freewheeling paths. |

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 |
|---|---|---|---|
| IPD90R1K2C3AT | Same die, halogen-free mold compound; identical electrical specs and thermal performance. | No functional difference; selected when halogen-free compliance is mandatory per customer specification. | Direct material substitution where RoHS+halogen-free certification is required. |
| IPP65R1K2C7 | 650 V rating, 1.2 Ω RDS(on), lower Qg (22 nC), same PG-TO252 package. | Not suitable for 900 V applications; limited to 230 VAC-only or DC-fed systems with <650 V bus. | Consider only for lower-voltage, higher-frequency designs where reduced switching loss outweighs voltage limitation. |
Compared with IPD90R1K2C3BTMA1, the AT variant offers identical performance with enhanced environmental compliance, while the IPP65R1K2C7 trades voltage headroom for lower gate charge-making it viable only in sub-650 V systems where efficiency at higher frequencies is prioritized.

FAQ
What is the maximum continuous drain current at 100 °C case temperature?
The IPD90R1K2C3BTMA1 supports 3.2 A continuous drain current at TC = 100 °C, as specified in the Absolute Maximum Ratings table. This value reflects thermal derating due to reduced channel conductivity and increased RDS(on) at elevated temperatures, and must be validated against actual PCB layout thermal resistance.
Does this MOSFET require a negative gate voltage for reliable turn-off?
No. The device has a gate threshold voltage (VGS(th)) of 2.5–3.5 V and is fully enhanced at VGS = 10 V. A gate drive swing of 0 V to 10 V is sufficient for robust turn-on and turn-off; negative gate bias is not required or recommended per datasheet guidelines.
Can IPD90R1K2C3BTMA1 replace older CoolMOS™ C2 devices in existing designs?
Yes, it is a direct drop-in replacement for IPD90R1K2C2 in most cases, offering improved RDS(on) × Qg, lower Coss, and enhanced dv/dt ruggedness. Layout changes are typically unnecessary, but gate drive strength and snubber tuning should be verified due to faster switching edges.
What is the significance of the 'B' suffix in the order code IPD90R1K2C3BTMA1?
The 'B' denotes the tape-and-reel packaging format (1,000 pcs/reel), while 'TMA1' indicates Infineon's standard industrial-grade marking and traceability code. This distinguishes it from tube-packaged variants (e.g., IPD90R1K2C3TMA1) and halogen-free versions (e.g., IPD90R1K2C3AT).
