Overview
The B170B-13 is a Schottky barrier rectifier manufactured by Diodes Incorporated, designed for surface mount applications. It features a single diode configuration within an SMB (DO-214AA) package. The device supports a maximum repetitive reverse voltage of 70 V and an average forward rectified current of 1 A. Key electrical characteristics include a maximum forward voltage of 790 mV at 1 A and a reverse leakage current of 500 µA at 70 V. The component operates reliably across a junction temperature range from -65°C to +150°C.
Feature Summary
- Utilizes Schottky barrier technology for low forward voltage drop and high efficiency.
- Incorporates guard ring die construction to provide protection against transient voltage events.
- Designed for automated assembly processes with lead-free terminals and matte tin finish.
Applications
- Low voltage, high frequency inverters
- Free wheeling diode circuits
- Polarity protection applications
Procurement Notes
Verify the specific suffix '13' corresponds to the standard tape and reel packaging format as defined in the official datasheet. Confirm that the required RoHS compliance and halogen-free status align with project specifications. Ensure the SMB package footprint matches the PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a 70 V reverse voltage rating and 1 A continuous current capacity are required in a compact SMB package. Consider the low forward voltage characteristic for improved efficiency in power conversion stages. Verify thermal management requirements given the wide operating temperature range up to 150°C junction temperature.
Part Context
This part belongs to the B1xxB series of high voltage Schottky barrier rectifiers from Diodes Incorporated. The series offers various voltage ratings while maintaining consistent current handling and package dimensions. The B170B-13 specifically addresses applications needing 70 V blocking capability with robust surge overload ratings suitable for demanding industrial environments.
Replacement Considerations
Cross-reference with other B170 variants such as B170Q or B170BQ if different package styles like SMA or SMB-Q are needed. Ensure substitute parts maintain the same 70 Vrrm and 1A If ratings. Verify compatibility with AEC-Q101 qualification standards if automotive reliability is required.
