The 1.5KE15A is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse. It is designed to protect sensitive electronic components from voltage transients induced by lightning, electrostatic discharge (ESD), inductive load switching, and other transient voltage events.

Applications

• Protection of I/O Interfaces
• Overvoltage protection in sensitive electronic equipment
• Lighting surge protection
• ESD protection
• AC and DC line protection

Features

• Unidirectional TVS Diode
• Glass passivated junction
• Excellent clamping capability
• Typical IR less than 1μA above 10V
• Fast response time: typically less than 1.0 ps from 0 Volts to BV min
• For surface mounted applications to optimize board space
• Low profile package
• Typical failure mode is short from over-specified voltage or current
• Whisker test is conducted based on JEDEC standard JESD201A per its table 4a and 4c
• IEC-61000-4-2 ESD 15kV(Air), 8kV (Contact)
• EFT surge protection per IEC-61000-4-4

Benefits

• Provides robust overvoltage protection
• Increases the reliability and lifespan of electronic devices
• Simplifies circuit design by providing a single-component solution
• Saves board space with its compact surface-mount package
• Offers a high level of protection against ESD and EFT surges
