The TPSMB13A-081M3/52T is a surface-mount Transient Voltage Suppressor (TVS) diode manufactured by Vishay. This component is designed to protect sensitive electronic circuits from transient voltage events such as electrostatic discharge (ESD), electrical fast transients (EFT), and lightning surges. It is part of the SMB series, known for its robust surge handling capability and compact size.

Applications

• Protection of data lines
• I/O port protection
• Power supply protection
• Automotive electronics
• Industrial control equipment

Features

• SMB package with low profile
• Excellent clamping capability
• Low incremental surge resistance
• Fast response time
• High surge capability
• Meets MSL level 1, per J-STD-020, LF maximum peak of 260 °C
• AEC-Q101 qualified

Benefits

• Provides reliable protection against voltage transients, enhancing system robustness.
• The SMB package offers a good balance between size and surge handling capability.
• Fast response time ensures quick clamping of transient voltages, minimizing stress on protected components.
• AEC-Q101 qualification ensures suitability for automotive applications.
• Reduces the risk of system failure due to transient voltage events.

Additional Details

The TPSMB13A-081M3/52T has a standoff voltage of 13V, meaning it will not conduct under normal operating conditions up to 13V. When the voltage exceeds this level, the TVS diode starts to conduct, clamping the voltage to a safe level to protect downstream components. The device is designed to handle high surge currents and is available in a unidirectional configuration. It is RoHS compliant and halogen-free, aligning with environmental standards.
