Key Features
- High-voltage sink driver with 8.5 A peak output current capacity for direct control of solenoids, relays, and ignition coils
- Integrated triple protection: transient voltage clamping, over-current limiting, and thermal shutdown ensure robust operation in harsh automotive environments
- Flange-mount 5-pin package with bolt-down mounting allows direct chassis attachment for superior heat dissipation without a separate heatsink
Applications
The VB027 is designed for automotive ignition coil drivers, fuel injector control modules, and industrial solenoid valve actuators where high peak sink currents up to 8.5 A must be switched reliably under transient-rich supply conditions. Its integrated over-current and thermal protection prevents destructive failures in engine control units exposed to 12 V or 24 V battery supply spikes. The flange-mount package allows direct mechanical mounting to the ECU chassis for low thermal resistance without additional heatsink hardware.

Frequently Asked Questions
What peak sink current does VB027 support, and what protection features prevent damage during inductive load switching?
The VB027 sinks up to 8.5 A peak output current when driving inductive loads such as solenoids or ignition coils. It includes three integrated protections: transient voltage clamping suppresses high-voltage spikes during coil turn-off, over-current limiting prevents damage from short circuits, and thermal shutdown disables the output when junction temperature exceeds the rated limit, protecting both the device and connected load.
How is VB027 mounted on a PCB, and does its flange-mount package enable chassis heat sinking?
The VB027 uses a flange-mount 5-pin TO-style package with a bolt hole that attaches directly to a metal chassis or heat spreader. This mechanical mounting arrangement provides a low-resistance thermal path to the chassis, allowing continuous dissipation of several watts without a separate heatsink component, which is important in compact automotive ECU designs with limited PCB real estate.
For an automotive fuel injector driver application, how does VB027 compare to a discrete MOSFET solution in terms of component count?
A discrete MOSFET fuel injector driver typically requires a gate driver IC, a clamp Zener diode rated above 30 V for inductive kickback, an NTC thermistor for thermal monitoring, and a current sense resistor plus comparator for over-current protection, totalling 5 or more components. The VB027 integrates all these functions into a single 5-pin device, reducing PCB area by over 60% and eliminating inter-component parasitics that can cause false triggering in 12 V automotive environments.
