IPA95R1K2P7XKSA1 Overview
A high-voltage power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-driven switch optimized to block hundreds to thousands of volts in the off-state and conduct current with minimal loss in the on-state. The CoolMOS P7 family belongs to the superjunction (SJ) MOSFET category, which uses a deep-pillar charge-balancing structure to push RDS(on) far below the silicon limit of conventional planar MOSFETs. Within the broader taxonomy, this part fits under N-channel power MOSFET -> discrete MOSFET -> discrete semiconductor -> semiconductor device.
Key electrical specifications include a 950V drain-to-source breakdown voltage (VDSS), 6A continuous drain current at 25Β°C case temperature (ID), and 27W power dissipation (Ptot) under TO-220-FP mounting. The 1026 mOhm RDS(on) at VGS=10V reduces conduction loss in flyback and forward converters. The fully isolated TO-220-FP package eliminates the need for an additional insulator pad and provides a wide creepage distance, simplifying PCB layout in consumer and industrial designs.
The CoolMOS P7 superjunction architecture integrates a fast-recovery body diode, integrated gate resistor, and Zener-protected gate that simplify paralleling and EMI filtering. These features reduce BOM count and improve reliability in PFC stages, flyback primary switches, and auxiliary supplies found in SMPS and lighting ballasts.
Typical applications include SMPS power supplies, LED lighting drivers, PFC front stages, and HV lighting ballasts. In each, the IPA95R1K2P7 delivers high efficiency at 400V+ rail voltages where conventional 600V MOSFETs would have inadequate safety margin.
When designing with this part, ensure gate drive voltage is at least 10V (12V recommended) to fully enhance the channel. The TO-220-FP isolation allows direct heatsinking without a thermal pad, but the 27W power dissipation still requires adequate airflow or a substantial heatsink at full load.

Typical Applications
IPA95R1K2P7XKSA1 is suitable for 6 applications: Flyback Primary Switch in SMPS, Power Factor Correction (PFC) Boost Stage, LED Lighting Drivers, High-Voltage Auxiliary Power Supply, HV Lighting Ballasts (HID/CMH), Industrial Switched-Mode Power Supply (SMPS).
Flyback Primary Switch in SMPS
The IPA95R1K2P7XKSA1's 950V VDSS and 6A continuous drain current make it well-suited as a primary-side switch in isolated flyback converters fed from 230V AC rectified mains. The CoolMOS P7 superjunction technology achieves RDS(on) of 1026 mOhm at VGS=10V, balancing conduction loss with switching loss for SMPS designs in the 30W-90W range. Designers place the MOSFET at the drain side of the transformer primary, with the isolated TO-220-FP tab allowing direct heatsink mounting without an additional insulator pad, simplifying PCB assembly and improving creepage distance to 4mm for safety compliance.
Recommended
Power Factor Correction (PFC) Boost Stage
For Power Factor Correction boost stages in consumer and industrial SMPS, the IPA95R1K2P7XKSA1 delivers robust 950V blocking margin against the rectified 385V DC bus plus inductive ringing. The CoolMOS P7 family integrates a fast-recovery body diode that simplifies CCM (Continuous Conduction Mode) PFC design and reduces reverse-recovery losses. The 27W power dissipation in TO-220-FP handles typical 100W-200W PFC stages with adequate heatsinking. Compared to older planar 900V MOSFETs, the P7 series reduces switching losses by 30-50%, improving overall PFC stage efficiency above 96%.
Recommended
LED Lighting Drivers
The IPA95R1K2P7XKSA1 fits high-voltage LED driver topologies that operate from 230V AC mains, including flyback, buck-boost, and isolated SEPIC converters. Its 950V VDSS provides safety margin above the 325V rectified peak, while the 6A ID handles dimming current peaks in commercial LED fixtures. The low RDS(on) of 1026 mOhm reduces thermal stress in enclosed luminaires where ambient temperature can reach 70C-80C. The isolated TO-220-FP package enables simple chassis-mount integration without additional insulation.
Recommended
High-Voltage Auxiliary Power Supply
For auxiliary supplies in three-phase industrial equipment (400V-690V AC rectified bus), the IPA95R1K2P7XKSA1 provides the 950V blocking voltage needed for safe operation. These typically 5W-15W supplies power fans, sensors, relays, and control electronics, where the CoolMOS P7's low RDS(on) keeps efficiency above 85% even at light loads. The integrated Zener-protected gate simplifies paralleling for higher current capability and provides ESD robustness during handling and PCB assembly.
Recommended
HV Lighting Ballasts (HID/CMH)
The IPA95R1K2P7XKSA1 drives the inverter stage in high-intensity discharge (HID) and ceramic metal-halide (CMH) ballasts fed from 230V AC mains. Its 950V VDSS handles the high-voltage strike pulses (3kV-5kV) that ignite the lamp and the sustained 600V bus during operation. The 6A drain current capacity suits ballast power levels up to 150W commercial lighting. CoolMOS P7's integrated Zener protection on the gate absorbs stray inductive spikes common in lamp-ignition circuits.
Recommended
Industrial Switched-Mode Power Supply (SMPS)
For industrial SMPS modules from 50W to 250W used in factory automation, PLC systems, and motor control auxiliary rails, the IPA95R1K2P7XKSA1 provides a robust primary-side switch for quasi-resonant flyback, half-bridge LLC, or two-switch forward topologies. The 950V VDSS handles 230V AC industrial mains with significant transient margin. Compared to TO-220 non-isolated packages, the Full Pack version eliminates the need for thermal-pad insulation, improving assembly yield and reducing long-term thermal interface degradation.

Key Differentiators
- Isolated Full Pack package eliminates thermal-pad insulator (vs STP6N95K5 (TO-220 non-isolated))
- Higher power dissipation in same-class package (vs IPB95R1K2P7ATMA1 (D2PAK surface-mount))
- Integrated Zener-protected gate simplifies paralleling (vs STP6N95K5)
Design Notes
The IPA95R1K2P7XKSA1 is rated for 27W power dissipation in PG-TO220-FP at TC=25C, derating linearly to ~9W at TC=110C. The isolated Full Pack tab eliminates the thermal resistance penalty of an additional insulator pad (typically 0.5-1.0 C/W). At maximum continuous drain current of 6A with RDS(on) of 1026 mOhm at hot, conduction loss reaches ~37W worst-case - exceeding the package rating. Designers must either derate current to 4-5A or provide substantial heatsinking (thermal resistance < 4 C/W).
Minimize the high-side switching loop (drain to transformer primary to VBUS return) by placing the MOSFET directly adjacent to the bulk capacitor and transformer primary winding. This loop area should be kept under 1 cm^2 to suppress voltage spikes and EMI. Use a gate-drive resistor of 10-47 ohm to balance switching loss (lower R) against EMI and gate ringing (higher R). The TO-220-FP isolated tab allows direct heatsink mounting but maintain a 4mm creepage distance from drain tab to low-voltage traces.
Do not drive the gate below the threshold or with insufficient voltage; partial enhancement dramatically increases RDS(on) and causes thermal runaway. Use a 12V gate drive (typical) rather than 10V to ensure full enhancement across the entire operating temperature range - VGS(th) shifts negative with cold and the RDS(on) specification at VGS=10V is only fully met above ~25C. Avoid using the part as a constant-current load in linear mode; the SOA is restricted to pulsed switching applications. Always provide a TVS diode or snubber across the primary winding to clamp drain-voltage overshoots below 950V.
