STMicroelectronics VNN1NV0413TR

Overview

VNN1NV0413TR from STMicroelectronics is a monolithic OMNIFET II fully autoprotected high-side Power MOSFET in SOT-223 package, featuring 250 mΩ on-state resistance, 1.7 A linear current limit, and integrated overvoltage clamp (40 V), thermal shutdown, and diagnostic feedback via input pin - used for robust DC–50 kHz switching in automotive body control modules and industrial I/O drivers.

For engineers reviewing the VNN1NV0413TR datasheet, VNN1NV0413TR pinout, VNN1NV0413TR application, or VNN1NV0413TR equivalent, this page delivers verified electrical specs, protection behavior under fault conditions, thermal derating curves, real-world switching performance at 330 Ω gate drive, and validated alternatives for high-reliability load switching designs.

Technical Context

The device implements a VIPower® M0-3 process-based high-side switch with direct gate access for analog driving, enabling precise current regulation and linear-mode operation. Its internal architecture integrates a voltage-controlled current limiter, junction-temperature-sensing thermal shutdown (150–200 °C trip), and bidirectional input-pin diagnostics (10–20 mA fault sink).

Protection logic operates independently of input voltage: overvoltage clamping activates at 40 V (typ), current limiting engages at 1.7 A (typ) regardless of VIN, and thermal reset occurs ~15 °C below shutdown threshold - ensuring fail-safe behavior during inductive load transients, short circuits, or ambient overheating.

FAQ

What is the maximum continuous drain current for VNN1NV0413TR under typical PCB cooling?

The device supports 1.7 A continuous drain current (typ) with linear current limiting active. At T_c = 25 °C on a standard FR4 board with 50 mm² copper, its thermal resistance (R_thj-amb = 70 °C/W) allows ~1.1 A continuous conduction before reaching 150 °C junction limit - actual rating depends on ambient temperature and heatsink design.

Can VNN1NV0413TR be used in parallel configurations for higher current handling?

No - the device lacks built-in current-sharing features such as matched R_DS(on) or thermal coupling. Parallel operation is not recommended due to unequal current distribution and risk of thermal runaway; STMicroelectronics specifies single-device use only per datasheet Section 3.

Does the input pin require an external series resistor for logic-level driving?

Yes - a minimum 330 Ω series resistor is required between driver and INPUT pin (R_{IN MIN}) to ensure proper turn-on/turn-off timing and prevent oscillation. This value is specified in Table 2 and validated in Figure 4 switching test circuit.

How does the diagnostic feedback signal behave during overtemperature events?

When junction temperature exceeds T_jsh (150–200 °C), the device sinks 10–20 mA through the INPUT pin. This current flows only if the external drive source presents sufficiently low impedance (<1 kΩ); it drops to zero once junction temperature falls below T_jrs (~135 °C), enabling automatic recovery without controller intervention.
