The TPSMB6.8AHE3_A/I is a surface-mount transient voltage suppressor (TVS) diode manufactured by Vishay. It's designed to protect sensitive electronic components from voltage transients induced by lightning, electrostatic discharge (ESD), inductive switching, and other transient voltage events. This TVS diode is part of the SMB series and is characterized by its low profile and excellent surge handling capability.

Applications

• Protection of I/O interfaces
• Data lines
• Power lines
• Automotive electronics
• Industrial control systems
• Consumer electronics

Features

• Unidirectional TVS diode
• Surface-mount SMB package
• Low profile
• Excellent clamping capability
• Glass passivated chip junction
• Low incremental surge resistance
• Typical IR less than 1 μA above 10 V
• Meets MSL level 1, per J-STD-020, LF maximum peak of 260 °C
• AEC-Q101 qualified available

Benefits

• Provides robust protection against voltage transients, improving system reliability.
• Low profile SMB package allows for compact designs.
• Fast response time to transient events ensures effective protection.
• High surge capability protects against high-energy surges.
• Easy to integrate into existing designs due to its standard package.

Additional Details

The TPSMB6.8AHE3_A/I has a stand-off voltage of 6.8V, meaning it does not conduct under normal operating conditions up to this voltage. It has a peak pulse power dissipation of 600W at 10/1000μs waveform. The clamping voltage at peak pulse current is an important parameter to consider in ensuring that downstream components are protected. Operating temperature range is -65°C to +150°C. The device is RoHS compliant and halogen-free.
