STMicroelectronics VNB20N07TR-E

Overview

VNB20N07TR-E from STMicroelectronics is a fully autoprotected monolithic Power MOSFET in the OMNIFET family, designed as a rugged replacement for standard N-channel MOSFETs in DC–50 kHz switching applications. It features 70 V drain-source clamp voltage, 0.05 Ω R_DS(on) at 10 V_IN, 20 A current limit, integrated thermal shutdown at 150 °C, and diagnostic feedback via the input pin. It is used in industrial motor control, solenoid drivers, and automotive body electronics where fault resilience is critical.

For engineers reviewing the VNB20N07TR-E datasheet, VNB20N07TR-E pinout, VNB20N07TR-E application, or VNB20N07TR-E equivalent, key selection criteria include its linear current limiting behavior, input-pin-based fault signaling, clamped avalanche energy rating (0.95 J), and compatibility with TTL-level drive despite internal gate buffering.

Technical Context

This device integrates a power MOSFET with analog gate control, linear current limiting, overvoltage clamping, and junction-temperature sensing on a single die using ST's VIPower M0 technology. Its input pin directly controls the gate but also serves dual roles: sourcing bias current (250–500 µA) and sinking fault current (20–50 mA) during thermal or short-circuit events.

The protection architecture operates independently of input voltage - current limiting activates at fixed I_lim (14–28 A), thermal shutdown triggers at ≥150 °C, and reset occurs at ≤135 °C. Fault detection is implemented by disconnecting the input from the gate and pulling it to ground through a 100 Ω internal resistor, enabling simple voltage-level monitoring.

FAQ

What is the maximum continuous drain current for VNB20N07TR-E?

The device has an internally limited drain current of 20 A under normal operation, with a peak capability of 28 A at lower input voltages (V_IN = 5 V). Actual continuous current depends on thermal design: at T_c = 25 °C, PowerSO-10 package supports 83 W dissipation, translating to ~13 A with typical R_DS(on) and layout.

How does the input pin provide fault feedback?

During overtemperature or short-circuit events, the internal protection circuit disconnects the input pin from the gate and connects it to ground through a 100 Ω resistor. This pulls the input voltage to near 0 V, detectable by any MCU ADC or comparator without additional components.

Can VNB20N07TR-E replace a standard MOSFET without circuit modification?

Yes - it uses the same gate-drive interface as a standard N-channel MOSFET but draws 250–500 µA bias current from the input pin. Layout must ensure adequate copper area under the tab for thermal performance, and the input pin must tolerate this small DC load.

Is VNB20N07TR-E qualified for automotive applications?

No - ST explicitly states this device is not designed or authorized for automotive, safety-critical, or aerospace use. It is intended for industrial and general-purpose applications. For automotive use, ST recommends AEC-Q100 qualified alternatives like the VNQ7E050AK.
