Diodes Incorporated presents the SMAJ120CA-13-F, a robust transient voltage suppression (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This product is a bidirectional TVS diode, meaning it can clamp voltage spikes coming from either polarity due to its symmetrical reverse breakdown voltage. It is an ideal choice for safeguarding voltage-sensitive components which require high reliability and performance.

Key Features

• Stand-Off Voltage: The SMAJ120CA-13-F has a stand-off voltage of 120V, ensuring protection for circuits operating near this voltage level.
• Peak Pulse Power: With a peak pulse power dissipation of 400 Watts at 10/1000μs waveform, this TVS diode can handle significant power surges without damage.
• Low Incremental Surge Resistance: The device offers excellent clamping capability with low incremental surge resistance, minimizing the voltage overshoot during a transient event.
• Fast Response Time: The diode provides a response time of less than 1 picosecond from 0V to BV min, ensuring quick protection for sensitive circuits.
• Operating Temperature Range: It operates over a wide temperature range from -55°C to +150°C, suitable for various industrial applications.

Applications

The SMAJ120CA-13-F is versatile and can be used in a variety of applications where transient voltage protection is critical. These include:

• Power supply circuits
• Communication systems
• Automotive systems
• Industrial electronics
• Consumer electronics

Quality and Environmental Compliance
