The 1SMC8.5CA is a Transient Voltage Suppressor (TVS) diode designed by Central Semiconductor Corp. It is specifically engineered to protect sensitive electronics from voltage transients that can occur due to events like lightning strikes, inductive load switching, and electrostatic discharge (ESD). It is part of the SMC series known for its robust design and reliable operation in challenging environments.

Applications

• Protection of I/O ports
• Overvoltage protection for sensitive circuits
• Data line protection in communication systems
• AC and DC power line protection
• Protection for microprocessors and memory chips

Features

• Glass passivated junction for enhanced reliability
• Excellent clamping capability to limit overvoltages effectively
• Low incremental surge resistance, minimizing the impact on normal circuit operation
• Very fast response time: Typically less than 1.0 ps from 0 Volts to BV minimum, enabling rapid protection
• Low reverse leakage current (IR typically less than 1 μA above 10 V)
• Guaranteed high temperature soldering: can withstand 260°C for 10 seconds at the terminals
• The plastic material used has UL flammability classification 94V-O

Benefits

• Ensures the reliable performance of electronic equipment by providing robust protection against voltage surges
