Overview
The B170B-13-F is a single Schottky barrier rectifier manufactured by Diodes Incorporated. It utilizes silicon technology and is housed in an SMB (DO-214AA) surface-mount package. The device supports a repetitive reverse voltage of 70 V and conducts a forward current of 1 A. Key electrical characteristics include a maximum forward voltage of 790 mV at 1 A, a reverse leakage current of 500 µA at 70 V, and a surge current rating of 30 A. It operates within a junction temperature range of -65°C to +150°C.
Feature Summary
- Schottky barrier construction for low forward voltage drop
- Silicon planar design for high reliability
- Surface-mount SMB packaging for automated assembly
Applications
- General-purpose rectification in power supplies
- Free-wheeling diodes in DC-DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm exact tape-and-reel specifications. Ensure the component meets required RoHS compliance standards for the target application. Cross-reference the DO-214AA footprint dimensions with PCB layout guidelines before finalizing procurement orders.
Selection Notes
Select this component when a 70 V reverse voltage rating and 1 A continuous forward current are required in a compact SMB package. Consider the 790 mV forward voltage drop for efficiency calculations. Verify that the 30 A surge current capability aligns with the circuit's inrush requirements and thermal management strategy.
Part Context
This part belongs to the B170 series of high-voltage Schottky barrier rectifiers from Diodes Incorporated. The series offers various voltage ratings within the same SMB package family, allowing for design flexibility. The B170B variant specifically targets applications requiring 70 V blocking capability with standard switching speeds.
Replacement Considerations
Direct substitutes include other manufacturers' 1 A, 70 V Schottky rectifiers in the SMB (DO-214AA) package. Verify pinout compatibility and ensure equivalent forward voltage and reverse leakage specifications match the original design requirements.
