Typical Applications
IPN50R2K0CEATMA1 is suitable for 6 applications: AC-DC Flyback Converter (Smartphone Charger), LED Lighting Ballast (Bulb and Downlight), Auxiliary Power Supply (White Goods and Home Appliance), Standby SMPS Module (TV and Set-Top Box), Power Factor Correction (PFC) Boost Stage, Adapter for Consumer Electronics (Tablet, E-Reader).
AC-DC Flyback Converter (Smartphone Charger)
The IPN50R2K0CEATMA1 fits quasi-resonant flyback converters for sub-25W smartphone and tablet chargers because its 500V VDS provides a 100V safety margin above the rectified 325V universal-mains bus, while 2000 mOhm RDS(on) keeps conduction loss under 1W at full 5V/3A load. In a typical 18W USB-PD adapter, the device switches at 65-100 kHz and delivers >87% average efficiency, with the SOT-223 footprint enabling PCB areas smaller than 40x40mm. The CoolMOS CE low Qg also reduces gate-drive losses, which matters when the controller is supplied from an auxiliary winding.
Recommended
LED Lighting Ballast (Bulb and Downlight)
The IPN50R2K0CEATMA1 is a strong fit for 5-15W LED lighting ballasts (GU10, MR16, E27 retrofit) where the 500V CoolMOS CE handles the rectified-mains bus in isolated flyback or buck topologies. Its SOT-223 footprint is significantly smaller than the DPAK traditionally used in this segment, enabling very compact driver boards that fit inside the bulb base. With 2000 mOhm RDS(on) and CoolMOS CE's fast switching, the device supports flicker-free dimming compatibility and meets EN 55015 EMI limits with a small input filter.
Recommended
Auxiliary Power Supply (White Goods and Home Appliance)
In washing machines, refrigerators, and induction cooktops, the IPN50R2K0CEATMA1 can serve as the main switch in a low-power auxiliary SMPS (typically 3-10W) that powers the MCU and display during standby. The 500V rating handles wide mains ranges including 380V DC bus conditions in fault scenarios, while 2000 mOhm RDS(on) keeps standby power below 300 mW per EU ecodesign regulations. SOT-223 is well-suited to compact PCBAs placed inside metal enclosures where heat dissipation is already managed.
Recommended
Standby SMPS Module (TV and Set-Top Box)
The IPN50R2K0CEATMA1 is well matched to standby supplies in TVs and set-top boxes that must maintain <0.5W power consumption in standby mode. Operating at 65 kHz in discontinuous-mode flyback, the CoolMOS CE's low Coss reduce circulating energy in the transformer, supporting high efficiency even at 50 mW output levels. The 500V rating comfortably exceeds the rectified 325V bus on universal-mains designs, and the small SOT-223 footprint fits on the standby secondary side of the main board.
Recommended
Power Factor Correction (PFC) Boost Stage
In low-power PFC boost stages (typically 50-150W) used in industrial LED drivers and small-format SMPS, the IPN50R2K0CEATMA1 can serve as the boost switch when the input is a single-stage configuration. Its 500V breakdown allows operation with a 400V PFC output bus, and CoolMOS CE's fast body diode with low Qrr simplifies CCM/DCM boundary-mode operation. The 3.6A ID rating supports continuous-mode operation at 100W with adequate heatsinking on the SOT-223 tab.
Recommended
Adapter for Consumer Electronics (Tablet, E-Reader)
The IPN50R2K0CEATMA1 fits small consumer adapters (10-20W) for tablets, e-readers, and wireless speakers because the SOT-223 footprint enables PCBAs in the 30x30mm range. Operating at 100 kHz quasi-resonant flyback with CoolMOS CE, the design can achieve DOE Level VI and EU CoC Tier 2 efficiency requirements with simple single-layer magnetics. The 500V rating provides robust surge immunity for hot-plug events on the AC input.

Key Differentiators
- Cost-optimized 500V CoolMOS CE with SOT-223 footprint (vs Standard DPAK 500V MOSFETs)
- Identical die available without -ATMA1 reel suffix (vs IPN50R2K0CE (without reel suffix))
- Higher voltage headroom option in same footprint (vs IPN60R1K5CEATMA1)
Design Notes
Estimated: The PG-SOT223-3 package has a typical theta_JA of around 80-100 C/W on a 1-square-inch copper pour (JEDEC EIA/JESD51 standard 2S2P test board). At 5W Tc-rated dissipation, junction-to-ambient temperature rise can exceed 250C without a heatsink. For continuous operation above 1-2W in TA=25C ambient, attach the tab to at least 1 cm2 of copper pour and ensure airflow is not blocked by nearby components.
Keep the drain trace short and wide to minimize switching-node ringing and EMI. Place the gate-drive resistor within 5mm of the gate pin to dampen parasitic inductance. Maintain at least 4mm creepage distance between the drain tab and any low-voltage secondary-side copper to meet IEC 62368-1 reinforced insulation requirements in isolated flyback designs.
Do not exceed the 500V VDS rating even during transient overshoot from leakage inductance - add an RCD snubber or use a higher-voltage IPN60R1K5CE variant if ringing exceeds 480V. The gate-source Zener protection (typically integrated) clamps transients to ~15V; avoid driving the gate above +/-20V absolute maximum. Verify avalanche energy rating (EAS) is within limits for the specific application fault scenario.
SOT-223 footprint pads should be per JEDEC TO-261AA (IPC-SM-782). The tab should be soldered with sufficient paste volume for thermal conductivity but not so much that solder wicks up the drain lead. Reflow profile follow JEDEC J-STD-020 MSL1 classification, peak temperature 260C for 20-40 seconds. A second-side copper pour on the PCB beneath the device can reduce theta_JA by 20-30%.
