Broadcom SS26-0B00-02: Technical Specifications and Application Overview
The Broadcom SS26-0B00-02 is a highly integrated, surface-mount Schottky Barrier Rectifier Diode designed for high-efficiency power conversion applications. This component is part of Broadcom's extensive portfolio of reliable semiconductor solutions, engineered to meet the demanding requirements of modern electronic designs.
Technical Specifications
This diode is configured as a dual common cathode device, meaning two independent diodes are housed within a single package with their cathodes connected internally. This configuration is particularly advantageous for compact circuit designs, such as in full-wave bridge rectifiers.
Key electrical characteristics define its performance envelope:
Average Forward Current (IF(AV)): 4A per diode, providing robust current handling capability.
Peak Forward Surge Current (IFSM): 100A, offering excellent resilience against unexpected current spikes.
Repetitive Peak Reverse Voltage (VRRM): 60V, making it suitable for a wide range of low-voltage power supplies.
Forward Voltage (VF): Typically 0.5V at 2A, a critically low value that minimizes power loss and heat generation, a hallmark of Schottky diode technology.
Operating Junction Temperature Range: -65°C to +125°C, ensuring stable operation across a wide range of environmental conditions.
The device is encapsulated in a Surface Mount Power Package (SMB), which is optimized for automated assembly processes and provides a low profile on printed circuit boards (PCBs).
Application Overview
The primary strength of the SS26-0B00-02 lies in its high switching speed and low forward voltage drop. These attributes make it an ideal choice for applications where efficiency and thermal management are paramount.
Its most common applications include:
Switch-Mode Power Supplies (SMPS): Serving as an output rectifier in DC-DC converters, AC-DC adapters, and power factor correction (PFC) circuits, where its fast recovery time reduces switching losses.
Reverse Polarity Protection: Safeguarding sensitive circuits from damage caused by incorrect power supply connection.
Freewheeling / Clamp Diodes: Used in inductive load circuits (e.g., with motors or relays) to suppress voltage spikes and protect switching components like MOSFETs or transistors.
General Purpose High-Efficiency Rectification: In any circuit requiring AC to DC conversion with minimal voltage loss, such as in automotive systems, consumer electronics, and industrial equipment.
The Broadcom SS26-0B00-02 stands out as a highly efficient and reliable solution for power management. Its optimized design, combining a low VF with a robust current rating in a compact SMB package, makes it a superior choice for designers aiming to maximize efficiency, reduce board space, and enhance the thermal performance of their power conversion stages.
