The TPSMA6.8A is a transient voltage suppressor (TVS) diode manufactured by Vishay. It's designed to protect sensitive electronic components from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). This TVS diode is commonly used in telecommunications equipment, industrial control systems, and consumer electronics to enhance system reliability and prevent damage from voltage surges.

Applications

• Protection against lightning surges
• ESD protection for I/O interfaces
• Voltage transient suppression in power supplies
• Overvoltage protection in automotive electronics
• Industrial control systems

Features

• Unidirectional TVS diode
• Fast response time
• Low clamping voltage
• High surge capability
• SMA package for surface mounting

Benefits

• Protects sensitive circuits from voltage transients.
• Enhances system reliability by preventing damage from surges.
• Provides fast and effective overvoltage protection.
• Easy to integrate into existing circuit designs.
• Compact size suitable for space-constrained applications.

Specifications

The TPSMA6.8A has a stand-off voltage (VRWM) of 6.8V, meaning it doesn't conduct until the voltage exceeds this level. Its breakdown voltage (VBR) is typically around 7.56V to 8.36V. The clamping voltage (VC) at a specified peak pulse current (IPP) is typically around 11.7V. The peak pulse power (PPP) is typically 400W at 10/1000μs waveform. It is packaged in an SMA (Surface Mount Axial) package. Refer to the Vishay datasheet for detailed specifications and application notes.
