Product details

Overview

VNB35N07TR-E from STMicroelectronics is a fully autoprotected monolithic power MOSFET based on VIPower M0 technology, designed as a rugged replacement for standard N-channel MOSFETs in DC–50 kHz switching applications. It features 70 V drain-source clamping, 35 A current limiting, 0.028 Ω R_DS(on) at V_IN = 10 V, and integrated thermal shutdown, short-circuit protection, and diagnostic feedback via the input pin-used in industrial motor control outputs and solenoid drivers.

For engineers reviewing the VNB35N07TR-E datasheet, VNB35N07TR-E pinout, VNB35N07TR-E application, or VNB35N07TR-E equivalent, key selection criteria include linear current limiting behavior, fault-sensing capability through the input pin, avalanche energy rating (2.5 J), gate-drive compatibility with TTL logic, and thermal shutdown/reset thresholds (150 °C / 135 °C).

Technical Context

This device integrates a power MOSFET with analog gate control, linear current limiting, overvoltage clamp, and junction temperature sensing-all on a single VIPower M0 die. Its input pin directly drives the internal gate but also serves dual roles: status feedback (sinking 50 mA during fault) and reverse clamp (-1 to -0.3 V).

Protection is autonomous and voltage-independent: thermal shutdown triggers at ≥150 °C and resets at ≤135 °C; current limit holds I_D at 35 A (V_IN = 10 V) regardless of V_DS; unclamped inductive switching is supported by 2.5 J single-pulse avalanche energy.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS Clamp	70 V - Internally clamped drain-source voltage protects against inductive kickback without external TVS.
R_DS(on)	0.028 Ω @ V_IN = 10 V, I_D = 18 A - Low conduction loss enables high-efficiency 35 A DC switching.
I_lim	35 A - Fixed linear current limit prevents destructive overcurrent during short circuits or stall conditions.
T_jsh / T_jrs	150 °C / 135 °C - Fast thermal cutoff and hysteresis prevent oscillation during overload recovery.
E_AS	2.5 J - Single-pulse avalanche energy rating allows safe operation under unclamped inductive turn-off stress.
Q_i	100 nC @ V_DD = 12 V - Input charge determines gate driver strength requirement for 100 ns turn-on delay.
V_IN(th)	0.8–3 V - TTL-compatible threshold enables direct microcontroller GPIO drive with minimal level-shifting.

Pinout & Package

Package: PowerSO-10 (surface-mount, exposed drain tab). Thermal resistance: R_thj-case = 1 °C/W, R_thj-amb = 50 °C/W.

Pin/Terminal	Circuit Role	Design Meaning
6, 7, 8, 9, 10	Input	Gate control input; sinks 50 mA during fault for open-drain status signaling; supplies internal bias current (250–500 µA).
1, 2, 4, 5	Source	Power source terminal; electrically common with internal sense resistor for current limiting and thermal sensing.
Tab (Drain)	Drain	High-current output path; thermally and electrically connected to heatsink; carries full load current and avalanche energy.

Key Features

Feature	Design Value
Integrated overvoltage clamp	70 V clamping with rugged avalanche capability eliminates need for external snubbers in inductive loads.
Linear current limiting	Fixed 35 A limit independent of input voltage ensures predictable fault behavior and simplifies system-level current sensing.
Thermal shutdown with hysteresis	150 °C trip / 135 °C reset provides robust thermal management without external thermostats or monitoring circuitry.
Fault feedback via input pin	Internal 100 Ω pull-down during fault enables simple voltage-level detection (≈0 V) using existing MCU GPIO.
TTL-compatible input threshold	0.8–3 V threshold allows direct drive from 3.3 V or 5 V microcontrollers without gate driver ICs.

Applications

Industrial Motor Control Output

Solenoid & Valve Driver

Use Scenario: Driving 24 V DC brushed motors in PLC I/O modules with frequent start/stop cycles and stall risk.

IC Role / Device Role / Timing Role: High-side or low-side power switch with real-time current limiting and thermal foldback.

Use Value: Prevents MOSFET destruction during locked-rotor events; eliminates need for separate current-sense amplifier and comparator.

Use Scenario: Controlling pneumatic solenoids in factory automation systems where inductive kickback and intermittent shorts occur.

IC Role / Device Role / Timing Role: Protected switching element with integrated clamp and fast fault reporting.

Use Value: Withstands 2.5 J unclamped inductive energy; fault signal enables immediate controller response (<100 µs detection latency).

Automotive Body Control Module

Heating Element Interface

Use Scenario: Managing window lifters, seat adjusters, and mirror actuators in 12 V automotive environments subject to load dump and reverse battery.

IC Role / Device Role / Timing Role: Smart power switch with ESD protection (2000 V HBM) and input-referenced fault signaling.

Use Value: Survives ISO 10605 ESD events; diagnostic feedback reduces need for dedicated fault lines in wiring harnesses.

Use Scenario: Switching resistive heating elements (e.g., defrosters, seat heaters) requiring precise thermal margin control.

IC Role / Device Role / Timing Role: Thermally self-protected power stage with junction temperature–based shutdown.

Use Value: Eliminates external thermal sensors; automatic restart after cooldown avoids manual reset in sealed enclosures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar protected power switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Integrated H-bridge driver with PWM control; lower current rating (2.8 A); no linear current limiting.	Targeted at stepper/servo motion control-not suitable for 35 A DC loads.	Select only for low-power bidirectional motor control where integrated gate driving and PWM are required.
VND5E025AKTR-E	Single-channel high-side switch; 25 A rated; built-in current sense (0.5 mΩ); no avalanche rating.	Lacks 2.5 J E_AS and 70 V clamp-requires external protection for inductive loads.	Prefer when precise current monitoring is needed and inductive energy is low or externally clamped.

Compared with STSPIN250 and VND5E025AKTR-E, VNB35N07TR-E uniquely combines 35 A linear current limiting, 70 V internal clamp, and 2.5 J avalanche robustness-making it the only choice for unprotected inductive switching at high current without auxiliary protection components.

FAQ

What is the maximum continuous drain current for VNB35N07TR-E?

The device features an internally limited drain current of 35 A at V_IN = 10 V and V_DS = 13 V. This is a linear current limit-not a pulsed rating-and sustained operation at this level requires careful thermal design due to elevated power dissipation in the linear region.

How does fault detection work on the input pin?

During overtemperature or short-circuit fault, the internal protection circuit disconnects the input from the gate and connects it to ground via a 100 Ω resistor. This pulls the input pin voltage near 0 V, enabling detection using a simple MCU GPIO with pull-up-no additional circuitry required.

Can VNB35N07TR-E be used in high-frequency PWM applications?

It supports switching up to 50 kHz, with typical turn-on delay of 100 ns and rise time of 350 ns (R_gen = 10 Ω). However, its linear current limiting and thermal protection are optimized for lower-frequency, high-energy switching-not high-frequency SMPS topologies where fast switching and low Q_g are critical.

Is external heatsinking required for 35 A operation?

Yes. With R_thj-case = 1 °C/W and P_tot = 125 W (PowerSO-10), even at T_c = 25 °C, junction temperature rises rapidly under 35 A linear limiting. A low-thermal-resistance heatsink and forced airflow are mandatory for sustained 35 A operation.
