BB145B,115

Overview

The BB145B,115 is a silicon planar switching diode manufactured by NXP USA Inc. It is housed in the SOD323 surface-mount package (R-PDSO-G2) and contains a single diode element. The device is RoHS compliant and classified under EAR99. Key electrical parameters include a maximum repetitive peak reverse voltage of 70 V and a maximum average forward rectified current of 200 mA. The component exhibits a low forward voltage drop of 1.25 V at 200 mA and maintains a very low leakage current of 1 µA at its rated reverse voltage.

Feature Summary

• Unidirectional switching capability for signal and power applications
• Low forward voltage drop to minimize conduction losses
• High surge current handling capacity for transient protection
• Plastic encapsulation designed for automated surface-mount assembly

Applications

• General-purpose signal switching circuits
• Power supply rectification stages
• Protection against reverse polarity in DC circuits
• Clamping and steering diodes in digital logic interfaces

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official documentation to confirm pinout orientation and marking codes, as variations exist within the family. Confirm RoHS compliance status for the specific production batch. Ensure the SOD323 footprint matches the design layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact surface-mount switching diode with moderate current ratings is required. The 200 mA average forward current rating suits low-power applications. Consider the 70 V reverse voltage limit for circuit compatibility. The SOD323 package offers space efficiency compared to larger through-hole alternatives while maintaining adequate thermal performance for standard operating conditions.

Part Context

The BB145 series belongs to NXP's portfolio of small-signal silicon switching diodes. These components are engineered for high-speed switching operations in consumer electronics and industrial control systems. The BB145B variant specifically denotes a particular marking or orientation configuration within the standard BB145 family, sharing identical electrical characteristics with other suffixes.

Replacement Considerations

Publicly confirmed substitute part numbers for the BB145B,115 were not identified in the provided reference material. Verify compatibility with generic SOD323 switching diodes such as the BAS16 or BAT54 series only if electrical parameters align with the application requirements.
