Explore immediate stock availability of high-demand WINSOK MOSFETs and custom configurations optimized for Indian power conditions and grid stabilities.
Driven by the "Make in India" initiative and the exponential growth of middle-class households, India's home appliance sector is transitioning from basic utility items to high-efficiency, smart-connected electronics. Local assembly and manufacturing clusters in Noida, Pune, Chennai, and Bengaluru have become centers of excellence. However, the success of local OEMs and ODMs hinges on securing high-quality power semiconductor supply chains.
India’s unique electrical environment—marked by seasonal voltage surges, high humidity, and extreme summer temperatures reaching 48°C—demands component-level ruggedness. The Home Appliance ADC (Advanced Driver Control) Series represents an essential design paradigm. It integrates Analog-to-Digital Converter technology with robust power switching. This ensures microcontrollers and power MOSFETs can survive harsh power anomalies and keep appliances running efficiently.
As the Bureau of Energy Efficiency (BEE) enforces stricter star ratings for energy efficiency in air conditioners, refrigerators, and brushless DC (BLDC) ceiling fans, system design engineers are moving from legacy silicon switches to low-resistance (RDS(on)), thermally-optimized surface mount MOSFETs.

Appliance manufacturers in India face unique environmental and regulatory conditions. Here is how Olukey ensures long-term operational reliability.
| Application Segment | Key Challenge in India | Technical Solution Route | Target Compliance Met |
|---|---|---|---|
| BLDC Ceiling Fans | voltage fluctuations (160V - 280V AC), space limitations | 100V DFN5X6-8 / SOT-223 Low RDS(on) MOSFETs paired with Cmsemicon 8-bit MCUs | BEE 5-Star efficiency, CISPR 15 EMI/EMC |
| Inverter Air Conditioners | High outdoor temperatures (50°C ambient), compressor load spikes | TO-220-3L 150V/250V N-channel MOSFETs with low thermal impedance ($R_{\theta JC} < 0.5$ °C/W) | IEC 60335-1, IS 1391 Part 2 (BIS) |
| Front-Load Washers | Stall currents, humid drum environments, moisture condensation | Dual-channel N+P (TO-252-4L) configurations with conformal coating compatibility | IPX4 ingress protection support, RoHS 3.0 |
| SMPS Power Supplies | Grid spikes, high-frequency switching interference | 400V - 650V High Voltage MOSFET stages with stable input capacitance ($C_{iss}$) | BEE standby power limits (<0.5W), UL 62368-1 |
Designing power electronics for the Indian market requires compliance with Bureau of Indian Standards (BIS) regulations and Bureau of Energy Efficiency (BEE) programs. Under these rules, appliances are rated from 1 to 5 stars. Achieving a 5-star rating requires reducing switching losses in the motor inverter stages.
Our newer MOSFET generations focus on minimizing Gate Charge ($Q_g$) and On-Resistance ($R_{DS(on)}$). Reducing the FOM (Figure of Merit: $R_{DS(on)} \times Q_g$) lowers thermal generation in sealed enclosures. This minimizes the need for bulky heatsinks, helping design engineers reduce total system bill-of-materials (BOM) costs.
