The TPSMC27A/9T is a Transient Voltage Suppressor (TVS) diode manufactured by Vishay. This device is designed to protect sensitive electronic components from voltage transients induced by lightning, inductive load switching, and Electrostatic Discharge (ESD). It is part of the SMC series, known for its robust surge handling capability and reliability.

Applications

• Protection of I/O Interfaces
• VCC bus protection
• Telecom applications
• Industrial control systems
• Medical equipment

Features

• SMC package with low profile
• Excellent clamping capability
• Low incremental surge resistance
• Typical IR less than 1 μA above 10 V
• High temperature soldering guaranteed: 260 °C/10 seconds at terminals
• Meets MSL level 1, per J-STD-020, LF maximum peak of 260 °C
• RoHS compliant

Benefits

• Provides robust overvoltage protection, enhancing system reliability.
• Compact size allows for use in space-constrained applications.
• Reduces the risk of damage from ESD and voltage transients.
• Increases product lifespan by protecting against electrical stress.
• High surge capability enables protection in harsh environments.

Additional Details

The TPSMC27A/9T has a stand-off voltage of 27V, meaning it will not conduct under normal operating conditions up to 27V. It starts to conduct and clamp the voltage when the voltage exceeds 27V. This TVS diode offers a fast response time to surge events and a high surge current capability. The '9T' likely refers to specific packaging or testing variations. The device is RoHS compliant and halogen-free. It is ideal for protecting sensitive equipment from transient threats.
