Technical Specifications

The SMF24A features a standoff voltage of 24V and a breakdown voltage typically around 26.7V to 29.5V. Its clamping voltage, the voltage level to which it limits transient surges, is approximately 41.4V at a specified peak pulse current. It has a surge capability of 200W at 10/1000µs waveform. The SMF24A is available in a small SOD-123FL package. The operating temperature range typically spans from -55°C to +150°C. The fast response time enables it to quickly react to transient events, providing effective protection. This TVS diode is designed for unidirectional applications, meaning it primarily protects against positive voltage transients, making it suitable for various industrial and consumer electronic devices.
