Product Overview: SMBJ45A-13-F from Diodes Incorporated

The SMBJ45A-13-F is a robust transient voltage suppressor (TVS) diode designed by Diodes Incorporated, a leading manufacturer in the semiconductor industry. This protective device is specifically engineered to shield sensitive electronic equipment from voltage spikes and transients induced by lightning, load switch, and other disruptive events. With its compact SMB (DO-214AA) package, it offers a practical solution for space-constrained applications while providing high surge capability.

Key Features

• Peak Pulse Power: The SMBJ45A-13-F can handle 600W of peak pulse power dissipation for an 10/1000μs waveform, ensuring reliable protection against high energy transients.
• Stand-off Voltage: It features a stand-off voltage of 45V, making it suitable for a variety of circuits that operate at this voltage level.
• Breakdown Voltage: The breakdown voltage ranges from 50.0V to 55.0V, providing a margin above the stand-off voltage to prevent premature clamping.
• Clamping Voltage: With a maximum clamping voltage of 72.7V at 8.3A, it ensures that the transient voltage seen by the protected component does not exceed a safe level.
• Uni-directional Protection: This device offers uni-directional protection, making it ideal for DC voltage applications where the polarity is fixed.
• Low Incremental Surge Resistance: The TVS diode exhibits low incremental surge resistance, which helps in maintaining the voltage protection level while under surge conditions.
• Environmental Compliance: It is compliant with RoHS and REACH environmental standards, minimizing the ecological footprint of electronic components.
