Overview
The B170BQ-13-F is a 1.0A high voltage Schottky barrier rectifier manufactured by Diodes Incorporated in the SMB (DO-214AA) surface-mount package. It features a peak repetitive reverse voltage of 70V and an average rectified output current of 1.0A at a terminal temperature of +125°C. The maximum forward voltage drop is 0.79V at 1.0A, with a maximum leakage current of 0.5mA at rated voltage and +25°C. The device supports a non-repetitive peak forward surge current of 30A and operates within a junction temperature range of -65°C to +150°C.

Procurement Notes
Verify that the ordered component matches the exact part number B170BQ-13-F to ensure correct voltage rating and packaging specifications. Confirm compliance with automotive quality standards if the application requires AEC-Q101 qualification. Check datasheet revisions for any updates to mechanical dimensions or electrical characteristics before finalizing procurement documentation.
Selection Notes
Select this component when a 70V reverse voltage rating and 1.0A continuous current capacity are required in a compact SMB package. Consider the low forward voltage drop for efficiency in low voltage applications. Ensure the thermal management design accommodates the specified operating temperature range and junction-to-terminal thermal resistance values provided in the datasheet.
Part Context
This component belongs to the B170BQ-B1100BQ series of high voltage Schottky barrier rectifiers from Diodes Incorporated. The series offers various reverse voltage options ranging from 70V to 100V while maintaining a consistent 1.0A current rating. All variants share identical physical packaging and general electrical characteristics except for their specific blocking voltage ratings.
Replacement Considerations
Direct substitutes within the same series include B180BQ-13-F, B190BQ-13-F, and B1100BQ-13-F, which offer higher reverse voltage ratings but maintain the same current and package specifications.
