The SMBJ48A-13 from Diodes Incorporated is a robust Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. This TVS diode is a unidirectional, surface-mount device that comes in the SMB (DO-214AA) package, making it suitable for automated assembly processes.

Key Features:

• Stand-Off Voltage (V_wm): 48V - This is the maximum voltage that the diode can withstand without conducting in its off state.
• Breakdown Voltage (V_br): 53.3V to 58.9V - The voltage at which the diode begins to conduct in the reverse direction.
• Peak Pulse Power Dissipation: 600W (@10/1000μs waveform) - The maximum power the diode can dissipate in a short duration pulse without damage.
• Maximum Clamping Voltage (V_c): 77.4V (@ I_pp) - The maximum voltage drop across the diode when subjected to its rated peak impulse current.
• Surge Capability: It can handle surge currents without degradation, ensuring long-term reliability and performance.
• Low Incremental Surge Resistance: Provides low resistance during surges, minimizing voltage drop and power dissipation.
• Operating Temperature Range: -55°C to +150°C - Suitable for a wide range of operating temperatures.

Applications:

The SMBJ48A-13 is ideal for protecting voltage-sensitive components which can be affected by transient voltage spikes, including:

• Industrial Systems
• Consumer Electronics
• Computer Systems
• Communication Systems
• Automotive Systems

This TVS diode is RoHS compliant and is designed for use in applications requiring high reliability and environmental sustainability. The SMBJ48A-13 is a critical component for designers looking to enhance system protection against transient overvoltages in a compact form factor.
