STMicroelectronics VNP5N07-E

Overview

VNP5N07-E from STMicroelectronics is a fully autoprotected monolithic power MOSFET built on VIPower M0 technology, functioning as a smart high-side switch with integrated linear current limiting (5 A), 70 V drain-source clamp, and thermal shutdown at 150 °C. It replaces standard MOSFETs in DC–50 kHz inductive load switching applications such as automotive solenoid drivers and industrial relay controls.

For engineers reviewing the VNP5N07-E datasheet, VNP5N07-E pinout, VNP5N07-E application, or VNP5N07-E equivalent, key selection criteria include its diagnostic feedback via input pin, 0.2 Ω R_DS(on) at 10 V_IN, fault sink current of 50 mA, and compatibility with TTL-level driving without external gate drivers.

Technical Context

The VNP5N07-E integrates protection logic directly into the power stage: overvoltage clamping activates at 55 V threshold and limits V_DS to 70 V (typ.), while linear current limiting holds I_D at 5 A (typ.) regardless of input voltage-enabling safe inductive turn-off without snubbers. Its internal gate driver connects the input pin directly to the MOSFET gate during normal operation, drawing only 250–500 µA supply current.

Fault detection relies on status feedback: during overtemperature or short-circuit events, the input pin is actively pulled to ground through a 100 Ω internal resistor, enabling simple microcontroller monitoring. Protection activation is independent of input voltage and triggered by on-die thermal sensing located in the power die region for <20 µs response.

FAQ

What is the maximum continuous drain current the VNP5N07-E can deliver?

The VNP5N07-E delivers up to 5 A continuously under thermal equilibrium with adequate heatsinking (R_thj-case = 4 °C/W). Its linear current limiter enforces this value regardless of input voltage, but sustained operation at I_lim increases junction temperature-thermal shutdown activates at 150 °C if case temperature exceeds design limits.

How does the diagnostic feedback function during a fault condition?

During overtemperature or short-circuit faults, the internal protection circuit disconnects the input pin from the gate and connects it to ground via a 100 Ω internal resistor. This pulls the input pin voltage near 0 V, providing a clear, low-impedance logic-low signal detectable by any microcontroller GPIO without external components.

Can the VNP5N07-E be driven directly from a 3.3 V microcontroller GPIO?

Yes-the input threshold voltage (V_IS(th)) ranges from 0.8 V to 3 V, making it compatible with 3.3 V logic. However, at 3.3 V input, R_DS(on) rises to ~0.28 Ω (vs. 0.20 Ω at 10 V), increasing conduction loss. For full performance, a 5 V or higher gate drive is recommended.

Does the VNP5N07-E require an external freewheeling diode when driving inductive loads?

No external freewheeling diode is required due to its integrated 70 V drain-source clamp and rugged avalanche energy rating (E_as = 0.2 J). The internal clamp safely dissipates inductive kickback energy during turn-off, eliminating the need for external diodes in most 24 V system designs.
