Diodes Incorporated SMBJ11A-13 - Robust Transient Voltage Suppression Diode

The SMBJ11A-13 from Diodes Incorporated is a high-quality 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 robust component is a part of the SMBJ series, which is recognized for its reliability and performance in safeguarding circuits by clamping excess transient voltages to a safe level before they can damage sensitive components.

With a stand-off voltage of 11V, the SMBJ11A-13 is capable of handling surge events with a peak pulse power dissipation of 600W for 10/1000μs waveforms, as defined by the IEC 61000-4-5 standard. This makes it an excellent choice for a wide range of applications where voltage spikes can pose a risk to the operation of electronic devices, such as consumer electronics, industrial systems, and telecommunication infrastructure.

The SMBJ11A-13 features a unidirectional configuration, which means it offers protection in one direction, making it suitable for DC voltage applications. It comes in a DO-214AA (SMB) package, which is compact and suitable for high-density circuit board designs. The device also boasts a low incremental surge resistance and fast response time, ensuring quick and effective protection when it is most needed.

Key specifications of the SMBJ11A-13 include:

• Stand-off Voltage (V_RWM): 11V
• Breakdown Voltage (V_BR): 12.2V to 13.5V
• Maximum Clamping Voltage (V_C): 18.2V
• Peak Pulse Current (I_PPM): 32.9A
• Operating Temperature Range: -55°C to +150°C

Engineers and designers can trust the SMBJ11A-13 to provide robust protection against transient overvoltage conditions, ensuring the longevity and reliability of their products. Its compliance with RoHS and REACH environmental standards also makes it an environmentally friendly choice for modern electronic designs. Whether incorporated into power supply units, sensitive microcontroller circuits, or communication ports, the SMBJ11A-13 is an essential component for safeguarding against electrical transients.
