STMicroelectronics VN02AN-11-E

Overview

VN02AN-11-E from STMicroelectronics is a high-side smart power solid-state relay built with VIPower technology, designed to drive grounded resistive or inductive loads in automotive and industrial control systems. It delivers 7 A continuous output current at Tc = 25 °C, features 60 V drain-source breakdown voltage, 0.35 Ω on-state resistance, integrated thermal shutdown, and open-drain diagnostic output for overtemperature indication.

For engineers reviewing the VN02AN-11-E datasheet, VN02AN-11-E pinout, VN02AN-11-E application, or VN02AN-11-E equivalent, key selection criteria include its -18 V fast demagnetization clamp for inductive loads, 5 V logic-compatible input, under-voltage lockout (3.5–7 V), status output behavior per truth table, and PENTAWATT vertical package thermal performance (R_thj-case = 4 °C/W).

Technical Context

The VN02AN-11-E integrates a high-side Power MOSFET with protection logic, thermal sensing, and diagnostic feedback in a monolithic VIPower structure. Its internal circuitry enables automatic thermal reset at 125 °C after shutdown at 140 °C, and implements fast inductive turn-off via active clamping to -18 V (typical) to limit energy dissipation.

Input logic thresholds are hysteresis-enabled (0.5 V), with VIH internally clamped at ~6 V and VIL at 0.8 V - supporting direct 5 V microcontroller interfacing. The open-drain STAT output sinks up to 1.6 mA and signals overtemperature (low) or undervoltage (low), while remaining high during normal operation.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous output current for VN02AN-11-E at 85 °C case temperature?

At T_c = 85 °C, the VN02AN-11-E delivers 3.5 A continuous output current, as defined by its derating curve (Figure "Output Current Derating" in datasheet page 7). This reflects thermal limits imposed by R_thj-case = 4 °C/W and maximum T_j = 150 °C. Operation above this requires forced cooling or reduced duty cycle.

How does the -18 V demagnetization clamp function during inductive turn-off?

The VN02AN-11-E actively pulls the OUT pin to approximately -18 V (typ.) when turning off inductive loads, creating a controlled reverse voltage path that accelerates current decay. This reduces demagnetization time and peak V_DS stress versus passive freewheeling diodes, lowering overall power dissipation in the switch and load.

Can VN02AN-11-E be used with a 5 V microcontroller without level shifting?

Yes - the IN pin accepts 5 V logic directly: V_IH (min.) = 2 V, V_IL (max.) = 0.8 V, with 0.5 V hysteresis. Input current remains below 300 µA at 5 V, and internal clamping limits voltage to ~6 V, eliminating need for external resistors or translators in standard 5 V MCU interfaces.

What failure modes does the STAT pin indicate, and how is it electrically configured?

The STAT pin is an open-drain output that pulls low during overtemperature (T_j ≥ 140 °C) or undervoltage (V_CC < 3.5 V). It remains high during normal operation. It sinks up to 1.6 mA and requires an external pull-up resistor (typically 4.7 kΩ to V_CC) for proper logic-level reporting to a microcontroller GPIO.
