Diodes Incorporated SMAJ130CA-13 - Product Overview

The SMAJ130CA-13 from Diodes Incorporated is a robust transient voltage suppressor (TVS) diode, designed to protect sensitive electronic equipment from voltage spikes and transient events that can cause irreversible damage. This TVS diode is specifically engineered to safeguard components in commercial, industrial, and portable electronics, including computers, consumer electronics, automotive systems, and telecommunication devices.

Key Features

• Bi-directional Surge Protection: The SMAJ130CA-13 offers bi-directional clamping, making it ideal for AC applications or where the polarity is reversible.
• High Surge Capability: With its ability to handle surges up to 400W (10/1000μs surge waveform), this device provides a high level of protection against transient overvoltages.
• DO-214AC (SMA) Package: The compact SMA package makes it suitable for high-density PCB layouts and offers a low profile in space-constrained applications.
• Stand-Off Voltage: It has a stand-off voltage of 130V, which is the maximum reverse voltage the diode can withstand without conducting.
• Temperature Range: The operating junction temperature range of -55°C to +150°C ensures stability and reliability across various temperature conditions.

Electrical Characteristics

The SMAJ130CA-13 is characterized by its quick response time to transient events, typically in the picosecond range. This ensures that sensitive circuitry is shielded from voltage spikes almost instantaneously. The device meets the ISO 7637-2 surge specification, making it suitable for automotive load dump protection. Furthermore, it complies with the IEC 61000-4-2 standard for electrostatic discharge (ESD) immunity, ensuring that it can withstand ESD events without degradation.

Applications

Common applications for the SMAJ130CA-13 TVS diode include power supply protection, data line and signal line protection, and voltage regulation for sensitive electronics. Its ability to rapidly clamp transient overvoltages and dissipate high surge energy makes it an essential component for enhancing the durability and reliability of electronic systems.

For designers and engineers looking for a reliable solution to protect their electronic designs from voltage transients, the SMAJ130CA-13 from Diodes Incorporated offers a perfect blend of performance, size, and thermal efficiency.
