STBP112CVDJ6F

Overview

The STBP112CVDJ6F is an overvoltage protection device designed for input voltages up to +28 V. It integrates a low RDS(on) N-channel MOSFET switch that disconnects the DC power supply upon detecting overvoltage, protecting systems connected to the OUT pin. The device complies with China MII Communications Standard YD/T 1591-2006. Key electrical features include a maximum continuous current of 2 A and an integrated charge pump. It offers thermal shutdown protection and soft-start functionality to control inrush current. The component is housed in a small, RoHS-compliant 8-lead TDFN package measuring 2 mm x 2 mm.

Feature Summary

• Provides immediate disconnection of DC power supplies during overvoltage events to prevent damage to protected components.
• Monitors internal junction temperature and switches off the MOSFET if limits are exceeded.
• Includes soft-start feature to manage inrush current during startup.
• Offers microcontroller controllability and fault status indication via dedicated pins.

Applications

• Protection of systems connected to OUT pins against DC power supply failures
• Compliance with China MII Communications Standard YD/T 1591-2006 requirements
• Overvoltage protection for input voltages up to +28 V

Procurement Notes

Verify the specific suffix DJ6F corresponds to the required tape and reel configuration when ordering. Confirm that the 8-lead TDFN package dimensions match the target PCB footprint. Ensure design compatibility with the +28 V maximum input voltage rating. Check for any specific handling requirements associated with the thermal pad on the TDFN package during assembly.

Selection Notes

Select this component when overvoltage protection up to 28 V is required for sensitive downstream electronics. The integrated N-channel MOSFET eliminates the need for external switching elements. Consider the 2 A continuous current capability for load requirements. The compact TDFN package suits space-constrained designs. Verify compliance with relevant regional communication standards if applicable to the end application.
