STMicroelectronics SMBJ130A-TR Transient Voltage Suppressor

The SMBJ130A-TR from STMicroelectronics is a robust and reliable transient voltage suppressor (TVS) diode, designed to protect sensitive electronic equipment from voltage transients induced by system inductive load switching and lightning. With its unidirectional configuration, this TVS diode is specifically engineered to safeguard voltage-sensitive components which are exposed to high voltage spikes.

The SMBJ130A-TR is housed in a compact SMB (DO-214AA) package, offering a practical solution for space-constrained applications while providing high surge capability. This diode is capable of clamping and dissipating the excess voltage to prevent damage to the protected component, making it an ideal choice for a variety of applications, including industrial, commercial, and consumer markets.

Key Features:

• Stand-off Voltage (V<sub>RWM): 130V, making it suitable for a range of overvoltage protection scenarios.
• Peak Pulse Power Dissipation: 600W (@10/1000μs waveform), ensuring a high level of protection against energy transients.
• Breakdown Voltage (V<sub>BR): 144V - 159V, providing a precise protection range.
• Maximum Clamping Voltage (V<sub>C): 209V (@ I<sub>PPM), which defines the maximum voltage the device will exhibit during a surge event.
• Peak Pulse Current (I<sub>PPM): 2.9A, indicating the maximum current the TVS can withstand during a surge event.
• Low Leakage Current: Minimizing power loss when the device is in standby mode.
• Operating Temperature Range: -55°C to +150°C, ensuring reliable operation under extreme conditions.
• Fast Response Time: Typically less than 1.0ps from 0V to V<sub>BR for unidirectional types, providing immediate protection against voltage spikes.

With its high surge capability and fast response time, the SMBJ130A-TR is a preferred choice for protecting voltage-sensitive components. Its compliance with the ISO 9001 and ISO 14001 standards reflects STMicroelectronics' commitment to quality and environmental management. Whether used in power supply circuits, communication systems, or other electronic devices, the SMBJ130A-TR is a reliable safeguard against transient overvoltage events.
