Frequently asked questions
What are the fundamental differences between the 2N7002 and the 2N7001TQDCKRQ1?
The 2N7002 is a widely available, single N-channel enhancement-mode MOSFET typically rated for 60 V VDS and 115 mA continuous drain current, commonly housed in SOT-23. The 2N7001TQDCKRQ1 is an automotive-qualified, single N-channel MOSFET in a 5-pin SC-70 (SOT-353) package, designed with a logic-level gate and specified for AEC-Q100 Grade 1 operation. They are not pin-to-pin or specification equivalents.
Can the 2N7002 and 2N7001TQDCKRQ1 be used interchangeably in a design?
No. The 2N7002 is a 3-pin SOT-23 device, while the 2N7001TQDCKRQ1 is a 5-pin SC-70 device with a different pinout and footprint. Electrical ratings, gate-threshold characteristics, and qualification levels also differ, so direct substitution requires full validation against the target circuit and manufacturer datasheets.
What is the difference in package and pin configuration between these two MOSFETs?
The 2N7002 uses the standard 3-lead SOT-23 package with pins for gate, source, and drain. The 2N7001TQDCKRQ1 uses a 5-lead SC-70 (SOT-353) package; the additional pins are typically used for improved thermal or electrical connection, and the pinout is not identical to the SOT-23. PCB land patterns are therefore not compatible.
Which of these two devices is automotive-qualified?
The 2N7001TQDCKRQ1 is automotive-qualified and is typically specified to AEC-Q100 Grade 1 requirements, making it suitable for automotive applications. The standard 2N7002 is a general-purpose commercial/industrial device and is not automotive-qualified unless a specific manufacturer offers an automotive-grade variant under a different part number.
How do the voltage and current ratings compare between the 2N7002 and 2N7001TQDCKRQ1?
The 2N7002 is typically rated at 60 V drain-source voltage and 115 mA continuous drain current. The 2N7001TQDCKRQ1 is a lower-voltage, logic-level MOSFET with ratings that differ from the 2N7002; designers must consult the specific manufacturer datasheet for exact VDS, ID, and power dissipation limits, as these are not interchangeable between the two part numbers.
Are the gate drive requirements the same for both devices?
No. The 2N7002 has a relatively high gate threshold voltage and is not always fully enhanced at low logic levels. The 2N7001TQDCKRQ1 is designed as a logic-level device with a lower threshold voltage, allowing it to be driven directly from low-voltage logic. Gate drive circuits must be evaluated separately for each part.
What applications are typically associated with each device?
The 2N7002 is commonly used in general-purpose switching, level shifting, and low-current load control in commercial and industrial electronics. The 2N7001TQDCKRQ1 is intended for automotive and other high-reliability applications where AEC-Q100 qualification and a compact SC-70 footprint are required.
What should be verified before replacing a 2N7002 with a 2N7001TQDCKRQ1?
Before replacement, verify pinout and footprint compatibility, VDS and ID ratings, gate threshold and drive voltage, power dissipation, thermal performance, and qualification requirements. The 5-pin SC-70 package of the 2N7001TQDCKRQ1 will not fit a 3-pin SOT-23 land pattern, so a PCB layout change is typically required.
