Overview
The B270BE-13 is a Schottky barrier rectifier manufactured by Diodes Incorporated. It features an average forward current of 1 A and a maximum repetitive peak reverse voltage of 70 V. The device utilizes silicon technology and is housed in an SMB (DO-214AA) surface-mount package. Key electrical characteristics include a forward voltage of 790 mV at 1 A, a reverse leakage current of 200 µA at 70 V, and a junction capacitance of 27 pF at 4 V and 1 MHz. It operates within a temperature range of -55°C to +150°C.
Feature Summary
- Utilizes Schottky barrier technology for high switching efficiency
- Designed for surface-mount installation in compact circuits
- Capable of withstanding high junction temperatures up to 150°C
Applications
- General-purpose rectification in power supply circuits
- Free-wheeling diodes in DC-DC converters
- Reverse polarity protection in electronic systems
Procurement Notes
Verify the specific suffix against official Diodes Incorporated documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with RoHS and REACH standards required for your region. Cross-reference the DO-214AA footprint dimensions with your PCB layout guidelines before finalizing procurement orders.
Selection Notes
Select this component when a low forward voltage drop and fast recovery are required for 1 A applications. Compare the 70 V rating against circuit peak voltages to ensure adequate safety margins. Consider the SMB package size constraints relative to available board space and thermal dissipation requirements for the specific enclosure design.
Part Context
This part belongs to the B-series of high-voltage Schottky rectifiers from Diodes Incorporated. The BE suffix typically denotes specific packaging or tape-and-reel configurations within the SMB form factor. It serves as a specialized variant optimized for surface-mount assembly processes compared to through-hole alternatives.
Replacement Considerations
Direct substitutes include the B270AE-13, which shares identical electrical ratings but uses the SMA (DO-214AC) package. Verify pinout compatibility and physical footprint differences before swapping between SMB and SMA variants in existing designs.
