STBP110GTDJ6F

Overview

The STBP110GTDJ6F is an overvoltage protection device designed for input voltages up to +28 V. It integrates a low RDS(on) N-channel MOSFET switch with a resistance of 170 mΩ and a maximum continuous current rating of 1.2 A. The component includes an integrated charge pump, thermal shutdown, and soft-start functionality to manage inrush current. It complies with the China MII Communications Standard YD/T 1591-2006 for overvoltage protection. The device features an enable input (EN) and a fault indication output (FLT), housed in a RoHS-compliant 8-lead TDFN package measuring 2 mm x 2 mm.

Feature Summary

• Provides immediate disconnection of DC power supply during input overvoltage conditions to protect downstream components
• Monitors internal junction temperature and automatically switches off the internal MOSFET if limits are exceeded
• Offers microcontroller control via enable input and provides status information through fault indication output

Applications

• Protection of systems connected to OUT pin against DC power supply failures
• Compliance with China MII Communications Standard YD/T 1591-2006 requirements
• Input voltage protection for electronic circuits operating up to +28 V

Procurement Notes

Verify the specific suffix 'GTDJ6F' against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Confirm obsolescence status as the base model STBP110 is listed as obsolete. Ensure compatibility with required ESD protection levels and thermal management requirements for the TDFN package.

Selection Notes

Select this component when input overvoltage protection up to 28 V is required alongside compliance with Chinese communication standards. Consider the integrated charge pump and low on-resistance for efficient switching. Evaluate the need for microcontroller controllability and fault reporting capabilities before choosing this integrated solution over discrete components.

Part Context

The STBP110 series belongs to STMicroelectronics' portfolio of overvoltage protection devices. These components integrate power switches and control logic to safeguard sensitive electronics from power supply anomalies. The STBP110 specifically targets applications requiring robust protection within compact footprints, utilizing advanced MOSFET technology for minimal power loss during normal operation.

Replacement Considerations

The base model STBP110 is marked as obsolete. Verify if other variants within the STBP series or alternative overvoltage protectors from STMicroelectronics are available as direct replacements. Cross-reference pinouts and electrical characteristics to ensure functional equivalence.
