The SA43A from ON Semiconductor is a robust transient voltage suppressor (TVS) diode, designed to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other transient voltage events. This TVS diode is a part of the SA series, known for its high surge capability and fast response time, making it an ideal choice for a variety of applications that require reliable protection against overvoltage conditions.

Key Features

• Transient Protection: The SA43A can handle peak pulse power up to 500 Watts for 1ms, safeguarding electronic components from sudden surges.
• Standoff Voltage: It has a standoff voltage of 43 Volts, providing a buffer zone where the diode remains non-conductive under normal operating conditions.
• Breakdown Voltage: The device features a minimum breakdown voltage of 47.8 Volts, ensuring it clamps down on overvoltages before they can damage the circuit.
• Low Leakage Current: With its low leakage current, the SA43A ensures minimal power loss when the device is in standby mode, contributing to energy efficiency.
• Fast Response Time: Its response time to transient events is less than 1 picosecond, providing immediate protection against voltage spikes.
• Operating Temperature Range: It operates over a wide temperature range from -55°C to +175°C, suitable for harsh environmental conditions.
• Package: The SA43A comes in an axial-lead package, facilitating easy installation and integration into various circuit designs.
