CRS08 – TOSHIBA

Overview

The TOSHIBA CRS08 is a high-performance Schottky barrier diode specifically designed for efficient DC-DC conversion and robust reverse-current protection. Its critical operational characteristic lies in its exceptionally low forward voltage drop (VFM), minimizing power dissipation and maximizing system efficiency, a crucial consideration in battery-powered mobile devices. However, designers must carefully balance this low VFM against the component’s repetitive peak reverse voltage (VRRM) rating, as exceeding this limit in transient conditions can lead to device failure, necessitating careful circuit design and component selection for optimal reliability.

Key Features

• Repetitive Peak Reverse Voltage (VRRM): 30 V
• Average Forward Current (IF(AV)): 1.5 A
• Maximum Peak Forward Voltage (VFM): 0.36 V
• Low-Profile S-FLAT™ Package (e.g., 2.0 x 1.6 x 0.7 mm)
• High Junction Temperature Capability
• Optimized for High-Frequency Switching Applications

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

• High-frequency rectification in buck/boost switching regulators
• Reverse-current blocking in portable power management ICs
• Input protection against accidental reverse polarity in consumer electronics
• Power sequencing and isolation in battery charging circuits
