Overview
The B140HW is a 1.0A surface mount Schottky barrier rectifier manufactured by Diodes Incorporated in an SOD123 package. It features a peak repetitive reverse voltage of 40V and an average forward current rating of 1.0A. The device exhibits a maximum forward voltage drop of 0.55V at 1A and 25°C, with a typical thermal resistance junction-to-ambient of 250°C/W. Operating temperature ranges from -65°C to +150°C.
Feature Summary
- Guard ring die construction for transient protection
- Low leakage current characteristics
- Low forward voltage drop
- Totally lead-free and fully RoHS compliant
Applications
- General purpose rectification
- Polarity protection circuits
- Free wheeling applications in low voltage high frequency inverters
Procurement Notes
Verify the specific datasheet revision (DS30670 Rev. 12) matches your design requirements. Confirm that the standard B140HW meets all necessary automotive reliability standards; if AEC-Q101 compliance is required, select the separate B140HWQ variant instead. Ensure packaging quantities align with production needs.
Selection Notes
Select this component for applications requiring a compact SOD123 footprint with 1A continuous current handling. Consider the 40V reverse voltage rating and low forward voltage drop for efficiency. Verify thermal management capabilities given the 250°C/W thermal resistance in free-air conditions.
Part Context
This part belongs to the 1.0A Surface Mount Schottky Barrier Rectifier family from Diodes Incorporated. It utilizes a molded plastic "Green" compound package with matte tin plated leads. The device is designed for automated assembly and offers halogen and antimony-free construction.
Replacement Considerations
For automotive-grade applications requiring AEC-Q101 qualification, use the B140HWQ variant. Other generic 1A 40V Schottky diodes in SOD123 packages may serve as functional substitutes if electrical parameters are verified against the official datasheet specifications.
FAQ
Is the B140HW qualified to AEC-Q101 standards?
No, the standard B140HW is not automotive-compliant. An automotive-compliant version is available under the separate part number B140HWQ.
What is the maximum non-repetitive peak forward surge current?
The maximum non-repetitive peak forward surge current is 16A for an 8.3ms single half sine-wave superimposed on rated load.
