NDP6020P P-Channel Power MOSFET — 20V / 24A, TO-220, Logic-Level, High-Side Switch

NDP6020P P-Channel Power MOSFET — 20V / 24A, TO-220, Logic-Level

The NDP6020P is a logic-level P-channel power MOSFET rated at -20V / -24A with an on-resistance of 45mΩ @ Vgs=-10V. P-channel MOSFETs are the natural choice for high-side switching — where the load sits between the MOSFET and ground — because they turn on when the gate is pulled LOW relative to the source, eliminating the need for a bootstrap gate driver circuit required by high-side N-channel configurations. The logic-level gate threshold allows direct drive from a 5V microcontroller in 12V high-side switch applications.

P-Channel vs N-Channel — When to Use Each

Configuration	N-Channel	P-Channel (NDP6020P)
Switch Position	Low-side (between load and GND)	High-side (between supply and load)
Gate Drive (turn ON)	Pull gate HIGH above source	Pull gate LOW below source
High-Side Drive Complexity	Requires bootstrap driver	✅ Simple — pull gate to GND to turn on
Rds(on) (same die size)	Lower (2–3× better)	Higher
Best For	Low-side, H-bridge, DC-DC	High-side load switch, reverse protection

Why Choose the NDP6020P?

• Simple high-side switching — connect source to 12V supply, drain to load; pull gate LOW to turn on — no bootstrap driver needed
• Logic-level gate — a 5V Arduino can drive the gate via an NPN transistor or N-channel MOSFET level shifter for clean switching
• Reverse polarity protection — P-channel MOSFETs are commonly used as ideal diodes for reverse polarity protection with near-zero voltage drop
• 24A continuous current — handles high-current 12V loads including motors, LED strips, and solenoids

Typical Applications

• High-side load switch for 12V systems (Arduino-controlled power switching)
• Reverse polarity protection (ideal diode replacement)
• P-channel high-side switch in H-bridge motor driver
• Battery charger power path management
• Automotive 12V accessory high-side switching
• Power sequencing and OR-ing circuits

Frequently Asked Questions

Q: How do I drive a P-channel MOSFET from a 5V Arduino for a 12V load?

Connect the source to 12V and the load between drain and GND. To turn ON: use an NPN transistor (e.g. 2N2222) or N-channel MOSFET with its collector/drain connected to the P-MOSFET gate via a pull-up resistor to 12V. When the Arduino drives the NPN base HIGH, it pulls the P-MOSFET gate LOW (to ~0V), turning it on. A gate resistor of 100–470Ω limits gate current spikes.

Q: Why is P-channel Rds(on) higher than N-channel?

P-channel MOSFETs use holes as charge carriers, which have lower mobility than electrons (used in N-channel). This means a P-channel die must be larger to achieve the same Rds(on), resulting in higher on-resistance for the same package size. For high-efficiency designs requiring low Rds(on), use an N-channel MOSFET with a bootstrap gate driver on the high side.
