Detailed Specs (Typical - Consult Datasheet)

• Breakdown Voltage: Around 3.3V. The '0R3' in the part number SF0R3G42 might refer to 0.3V, but it most likely refers to 3.3V, confirm with the datasheet.
• Clamping Voltage: Varies depending on the surge current, typically a few volts above the breakdown voltage.
• Reverse Standoff Voltage: A voltage below the breakdown voltage at which the diode exhibits very low leakage current.
• Peak Pulse Current (Ipp): A measure of the surge current the diode can withstand (e.g., 8/20 μs pulse).
• Operating Temperature Range: Typically -55°C to +125°C.
• Package Type: SOD-323 or similar small outline package.

The Toshiba SF0R3G42 TVS diode provides essential protection against voltage surges and ESD in a compact and reliable package. Its low clamping voltage and fast response time make it an ideal choice for safeguarding sensitive electronic components in a wide range of applications.
