Typical Applications
IPN95R1K2P7ATMA1 is suitable for 6 applications: Auxiliary SMPS for White Goods, LED Lighting Drivers, Industrial SMPS Modules, E-Bike and E-Scooter Chargers, Smart Meter and IoT Gateways, Standby Power for Home Appliances.
Auxiliary SMPS for White Goods
The IPN95R1K2P7ATMA1 is ideal for 5 W to 30 W auxiliary supplies in white goods such as washing machines, refrigerators, and dishwashers. Its 950 V breakdown handles the rectified 230 V AC mains plus inductive ringing from the main motor drives, while the 1.2 Ohm R_DS(on) at V_GS = 10 V keeps conduction losses low in discontinuous-mode flyback. The SOT-223-3 footprint is hand-solderable, simplifying field repair.
Recommended
LED Lighting Drivers
The IPN95R1K2P7ATMA1 fits mains-isolated LED driver topologies from 3 W to 25 W output, including isolated buck-boost and flyback designs. Its 950 V V_DSS absorbs the leakage spike from compact transformers used in low-cost LED bulbs, eliminating the need for RCD snubbers in many designs. The 6 A continuous drain rating supports start-up inrush for large capacitive loads.
Recommended
Industrial SMPS Modules
The IPN95R1K2P7ATMA1 suits industrial DIN-rail SMPS modules in the 10 W to 30 W range that must operate from three-phase rectified 400 V AC. With 950 V breakdown it tolerates 480 V AC nominal inputs plus transient overvoltages up to 550 V DC. The SOT-223-3 footprint provides a large source tab for thermal dissipation, helping maintain junction temperature within safe limits at full load.
Recommended
E-Bike and E-Scooter Chargers
The IPN95R1K2P7ATMA1 is well matched to 36 V to 48 V battery chargers in the 30 W to 65 W range used for e-bikes and e-scooters. Its 950 V breakdown tolerates the high leakage inductance spike of universal-input flyback transformers, while its low figure-of-merit (R_DS(on) x Q_G) keeps full-load efficiency above 88 percent. The compact SOT-223-3 package minimizes charger PCB footprint.
Recommended
Smart Meter and IoT Gateways
The IPN95R1K2P7ATMA1 fits the auxiliary supply of smart electricity meters and IoT gateways, where a small SMPS derives 5 V or 12 V from the 230 V AC line. Its 950 V V_DSS provides safety margin in compliance with IEC 61010 overvoltage categories, while the 7 W power dissipation rating supports continuous operation at elevated ambient temperature inside a sealed enclosure.
Recommended
Standby Power for Home Appliances
The IPN95R1K2P7ATMA1 is well suited for standby supplies that keep microcontroller-based appliances alive when the main load is off. A small 1 W to 3 W flyback converter using this part can maintain <50 mW no-load consumption, satisfying the EU eco-design directive for standby power. The 950 V rating provides robustness against line-side transients without external MOV protection.

Key Differentiators
- Higher breakdown voltage than 700 V alternatives (vs IPN70R1K0P7S)
- Lower R_DS(on) than the 950 V SOT-223 alternative in the same family (vs IPN95R2K0P7)
- Cross-brand 950 V SOT-223 pin compatibility (vs TK4A95DA)
Design Notes
Estimated: at full 6 A drain current and 1.2 Ohm R_DS(on), conduction loss is approximately 43 W (P = I^2 x R = 36 x 1.2). Since the package is rated for only 7 W at T_C = 25C, the IPN95R1K2P7ATMA1 cannot be operated at 6 A continuous unless the case is held below 25C. In practice the part is used at 0.5-1.5 A continuous in flyback converters, keeping conduction losses in the 0.3-2.7 W range. The SOT-223-3 source tab must be soldered to at least 50 mm^2 of 2 oz copper on a 1.6 mm FR-4 PCB to keep junction temperature below 150C in a 70C ambient.
Route the gate drive trace away from the drain node to minimize parasitic feedback through C_gd. Keep the gate-source loop area below 25 mm^2 by placing the gate pull-down resistor (10-100 kOhm) directly between gate and source pins, adjacent to the IC. For the SOT-223-3 footprint, the drain tab also serves as the thermal pad - use multiple thermal vias (8-12 vias of 0.3 mm diameter) to a bottom-side copper pour for best heat extraction.
Do not exceed V_DSS = 950 V even in transient spikes - in flyback topologies the leakage inductance spike can easily exceed the steady-state DC link. Either use an RCD snubber or select a transformer with tight coupling. Also note that the IPN95R1K2P7ATMA1 is specified for 10 V gate drive to achieve the datasheet R_DS(on); driving it with a 5 V logic-level signal will significantly increase conduction losses.
Compliance Information
