The 2N7002 is a popular N-channel enhancement mode MOSFET manufactured by Nexperia, a leading semiconductor company. Its characteristics, specifications and common applications are as follows:
feature:
1. Low threshold voltage: The 2N7002 MOSFET has a low threshold voltage, typically around 2.1 volts. This allows efficient switching using low-level control signals, making it suitable for low-power applications.
2. Fast Switching Speed: MOSFETs offer fast switching speed for fast switching transitions. This feature is beneficial for applications requiring fast response times, such as switching circuits or digital logic gates.
3. Low on-resistance: The 2N7002 has low on-resistance (RDS(on)) to minimize power dissipation and maximize efficiency. This is especially beneficial in battery-powered devices or applications where power efficiency is critical.
4. Compact and durable: Nexperia's 2N7002 is available in various compact surface mount packages such as SOT-23 and SOT-323. These small package sizes allow space-saving PCB layout for applications where board space is limited. Additionally, the device is designed to withstand harsh environments for durability and reliability.
Specification:
1. Drain-Source Voltage (VDS): The maximum drain-source voltage rating of the 2N7002 is typically 60 volts. It can withstand voltage levels within this range during operation.
2. Drain Current (ID): The maximum continuous drain current rating (ID) of the MOSFET is approximately 300 mA. This specification represents the maximum current that can flow through the device under normal operating conditions.
3. Gate-Source Voltage (VGS): The maximum gate-source voltage (VGS) of the 2N7002 is typically ±20 volts. It defines the voltage range that can be applied to the gate terminal to ensure proper operation.
4. Total Gate Charge (Qg): The total gate charge specifies the amount of charge required to fully turn the MOSFET on or off. The 2N7002 typically has low total gate charge for efficient and fast switching.
Common applications:
1. Switching circuit: Nexperia's 2N7002 is often used in low-power switching circuits to control the on-off status of various components, such as relays, LEDs, and small motors.
2. Level shifting: It can be used in level shifting applications that require voltage shifting to shift signals between different logic voltage levels.
3. Load switch: MOSFETs are suitable for load switch applications to control power or load connections in equipment such as power management modules and battery-powered systems.
4. LED Driver: Due to its low on-resistance and high-efficiency switching capability, 2N7002 is often used in LED driver circuits to control the brightness of LEDs.
