- FQP27P06 (Fairchild/ON Semi)
- NDP6020P (ON Semiconductor)
Check datasheets for exact specs (voltage, current, RDS(on)) before substitution. Some may require minor circuit adjustments.
Pinout
Key Functions:
- Drain (D), Source (S), and Gate (G) connections for power switching.
- Low On-Resistance (RDS(on)) for efficient power handling.
- High-Side Switching capability in P-channel configurations.
- Logic-Level Gate Drive (compatible with 4.5V drive).
Pinout (Typical SO-8):
1-3: Drain (D)
4: Gate (G)
5-8: Source (S)
Commonly used in power management, load switching, and battery protection circuits.
Application
1. Power Management – Switching and load control in DC-DC converters.
2. Battery Protection – Reverse polarity and overcurrent protection.
3. Motor Control – Driving small motors in portable devices.
4. Load Switching – Power distribution in consumer electronics.
5. Portable Devices – Efficient power handling in smartphones, tablets, and wearables.
Its low on-resistance and compact package (SOIC-8) make it ideal for space-constrained, energy-efficient applications.
