STMicroelectronics VNP20N07

Overview

VNP20N07 from STMicroelectronics is a fully autoprotected monolithic VIPower MOSFET designed as a rugged replacement for standard N-channel power MOSFETs in DC–50 kHz switching applications. It integrates linear current limiting (20 A typ.), overvoltage clamp (70 V), thermal shutdown (150 °C), diagnostic feedback via input pin, and direct gate access for analog driving. Used in industrial motor control, solenoid drivers, and DC load switching where fault resilience is critical.

For engineers reviewing the VNP20N07 datasheet, VNP20N07 pinout, VNP20N07 application, or VNP20N07 equivalent, key selection considerations include its integrated protection architecture, 0.05 Ω R_DS(on) at 10 V_IN, TO-220 package thermal performance (R_thj-case = 1.5 °C/W), fault-sink capability (50 mA), and compatibility with TTL-level drive.

Technical Context

The VNP20N07 implements a self-protected power switch architecture using ST's VIPower M0-3 process. Its internal circuitry combines a high-voltage DMOS output stage with dedicated protection blocks: a voltage-clamp network triggered at 55 V (V_CLTH) and clamping to 70 V (V_CLAMP), a linear current limiter active at 14–28 A depending on input voltage, and junction-temperature sensing with 150 °C shutdown and 135 °C auto-restart thresholds.

During fault conditions, the device disconnects the input pin from the gate and sinks up to 50 mA through a 100 Ω internal path to ground-enabling simple status detection. The input pin also supplies internal bias (I_ISS = 250–500 µA at 10 V), and supports direct analog gate control without external level-shifting.

FAQ

What is the maximum continuous drain current rating for VNP20N07?

The VNP20N07 does not specify a fixed continuous drain current rating due to its thermal and current-limiting architecture. Its usable current depends on PCB layout, heatsinking, and ambient temperature. With proper heatsinking (R_thj-amb ≤ 30 °C/W), it reliably handles 10–15 A continuous; peak current is limited to 20 A by internal linear regulation before thermal shutdown activates.

Can VNP20N07 be used in high-side configuration?

Yes, the VNP20N07 supports both high-side and low-side configurations. In high-side use, the source terminal connects to the load, and the drain connects to the positive rail. Its input pin remains referenced to system ground, enabling direct microcontroller interface without level-shifting, provided the load common is grounded.

How does the diagnostic feedback function during overtemperature fault?

When junction temperature reaches 150 °C, the internal protection circuit disconnects the input pin from the gate and connects it to ground through a ~100 Ω internal resistor. This pulls the input pin voltage near 0 V, allowing detection with a simple pull-up resistor and MCU GPIO or ADC-no additional components required for basic fault indication.

Is external flyback protection required when switching inductive loads?

No external flyback diode is required. The VNP20N07 integrates an internal overvoltage clamp that activates at 55 V and limits drain-source voltage to 70 V, combined with 0.95 J avalanche energy rating. This protects against inductive kickback in typical 24 V/48 V systems, though external clamping may still be advised for extreme dI/dt or >70 V bus applications.
