STMicroelectronics VNP35N07FI

Overview

VNP35N07FI from STMicroelectronics is a fully autoprotected monolithic Power MOSFET in the OMNIFET family, fabricated using VIPower M0 technology. It delivers 70 V drain-source clamping, 0.028 Ω R_DS(on) at 10 V gate drive, and 35 A current limit, operating from DC to 50 kHz. It serves as a rugged, self-protected high-side or low-side switch in automotive body control modules driving inductive loads such as solenoids and lamps.

For engineers reviewing the VNP35N07FI datasheet, VNP35N07FI pinout, VNP35N07FI application, or VNP35N07FI equivalent, key selection criteria include integrated overvoltage clamp (70 V), linear current limiting (35 A), thermal shutdown (150 °C), diagnostic feedback via input pin, and compatibility with TTL-level logic drivers without external level-shifting.

Technical Context

The VNP35N07FI integrates a power MOSFET stage with on-die protection circuitry including an overvoltage clamp (V_CLAMP = 70 V), linear current limiter (I_LIM = 35 A), and thermal shutdown (T_JSH = 150 °C). Its input pin directly connects to the internal gate during normal operation but switches to a 100 Ω fault sink path during overtemperature events.

It features built-in ESD protection (2000 V HBM), reverse diode recovery (t_rr = 250 ns), and diagnostic capability via input pin voltage monitoring. The device operates with a typical transconductance of 25 S and output capacitance of 1400 pF, enabling robust switching in harsh automotive environments.

FAQ

Can VNP35N07FI be used in high-side configuration?

Yes - the VNP35N07FI supports both high-side and low-side configurations. Its INPUT pin connects directly to the internal gate, and SOURCE pins serve as the reference node. In high-side use, SOURCE connects to load, DRAIN to supply, and INPUT receives control signal referenced to SOURCE potential.

What happens during overtemperature fault and how is it signaled?

At junction temperature ≥150 °C, the device disables the gate connection and pulls the INPUT pin to ground through a 100 Ω internal resistor. This causes the input voltage to drop near 0 V, detectable by any MCU GPIO. Auto-restart occurs only after junction temperature falls below 135 °C.

Is external flyback diode required when switching inductive loads?

No - the integrated 70 V overvoltage clamp and 2.5 J single-pulse avalanche energy rating eliminate the need for an external flyback diode in most 12 V/24 V automotive and industrial inductive load applications, reducing BOM count and PCB area.

How does the linear current limit differ from traditional current limiting?

Unlike foldback or shutdown-only limits, the VNP35N07FI enters linear mode at I_LIM, maintaining constant current while allowing V_DS to rise - enabling controlled energy dissipation and continued operation during temporary overloads, provided thermal design accommodates the resulting power.
