Overview
The ZXSBMR16PT8TA is a Schottky bridge rectifier combined with a freewheel diode designed for MR16 LED drive applications. It features a maximum repetitive reverse voltage of 40V and an average rectified forward current of 0.4A. The device operates within a junction temperature range up to 150°C, with a specified internal ambient temperature limit of 90°C for enclosed circuits. Electrical characteristics include a typical forward voltage of 305mV at 50mA and a reverse leakage current of 10µA at 30V. Packaged in an SM-8 surface mount case, it is supplied in tape and reel format.
Feature Summary
- Integrated Schottky bridge and freewheel diode optimized for MR16 LED driver circuitry
- Low forward voltage drop and low reverse leakage current for improved efficiency
- Qualified to AEC-Q101 standards for high reliability automotive-grade performance
Applications
- MR16 LED drive solutions
- Compact surface mount power management circuits
- Low voltage AC-DC conversion stages
Procurement Notes
Verify the specific ordering suffix TA indicates tape and reel packaging containing 1000 units per reel. Confirm that the SM-8 package dimensions match your PCB footprint requirements. Ensure thermal design accounts for the 90°C maximum internal ambient temperature constraint when operating within enclosed MR16 fixtures.
Selection Notes
Select this component when designing MR16 LED drivers requiring a compact solution with reduced component count. Verify compatibility with the ZXLD1350E5 controller as referenced in Design Note DN86. Consider the 40V reverse voltage rating and 0.4A current capacity against your specific load requirements.
Part Context
This part belongs to the ZXSBMR16 series of integrated rectifiers manufactured by Diodes Incorporated under the Zetex brand. It combines a bridge rectifier and a freewheeling diode into a single SM-8 package to minimize board space. The device is specifically engineered for low-profile lighting applications where thermal constraints are critical.
Replacement Considerations
The ZXSBMR16PT8 is the non-reel variant of this component. Verify if standard tube or loose piece packaging is acceptable for your assembly process before substituting.
