Overview
The B270-13 is a single-phase Schottky barrier rectifier manufactured by Diodes Incorporated in the SMB (DO-214AA) surface-mount package. It features a maximum repetitive reverse voltage of 70 V and an average rectified output current of 2.0 A at 125°C. The device exhibits a forward voltage of 0.79 V at 2.0 A and 25°C, with a peak reverse current of 0.5 mA at rated blocking voltage. It supports a non-repetitive peak forward surge current of 50 A and operates within a junction temperature range of -65°C to +150°C.
Feature Summary
- Guard ring die construction provides transient protection capabilities
- Low power loss characteristics ensure high efficiency operation
- Suitable for automatic assembly processes
- High temperature soldering capability up to 260°C for 10 seconds
Applications
- Low voltage, high frequency inverters
- Free wheeling circuits
- Polarity protection applications
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging and compliance details. The standard B270-13 designation indicates tape and reel shipping quantities. Confirm RoHS compliance status if lead-free finish is required, as this may necessitate a different suffix such as -F. Ensure the procurement request matches the exact manufacturer part number to avoid substitution errors.
Selection Notes
Select this component for designs requiring a 70 V reverse voltage rating and 2 A continuous current handling in an SMB package. Consider the thermal resistance of 15°C/W and derating curves when calculating heat dissipation. Verify that the operating environment stays within the specified -65°C to +150°C temperature range. Evaluate the 50 A surge current capability against potential inrush conditions in the target circuit.
Part Context
This device belongs to the B270-B2100 series of high voltage Schottky barrier rectifiers from Diodes Incorporated. The series offers varying reverse voltage ratings from 70 V to 100 V while maintaining a consistent 2.0 A average rectified current capacity. All variants share the same SMB surface-mount mechanical footprint and electrical performance characteristics regarding forward voltage and surge current.
Replacement Considerations
Check for B270-13-F for lead-free compliant versions. Verify pinout compatibility with other SMB packaged Schottky diodes offering 70 V and 2 A ratings before substitution.
