Littelfuse Uni-Directional TVS Diode Surface Mount DO-214 Package 1.5 kW Peak Pulse Power SMCJ15A

Littelfuse SMCJ15A is a single-element uni-directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic and electrical circuits from transient voltage spikes and surges. Packaged in a compact DO-214 surface mount format, this diode delivers a robust peak pulse power rating of 1.5 kilowatts, enabling reliable suppression of high-voltage transient events on power lines and signal interfaces.

Operating within a broad temperature range from -65°C to 150°C, the SMCJ15A ensures consistent protection performance in industrial, automotive (non-certified), telecommunications, and consumer electronics applications. Its minimum breakdown voltage of 16.7 volts and maximum reverse standoff voltage of 15 volts make it suitable for circuits requiring low voltage transient clamping, while its clamping voltage of 24.4 volts limits peak voltage spikes effectively.

The device supports a high maximum peak pulse current of 61.5 amps, protecting systems from severe transient surges such as lightning strikes, load switching, and electrostatic discharge (ESD). Its low maximum reverse leakage current of just 1 microampere contributes to energy efficiency in protected circuits. The 2-pin configuration and compact dimensions (7.11 mm length, 6.22 mm width, 2.417 mm height) facilitate easy integration into tight PCB layouts using surface-mount technology.

Littelfuse SMCJ15A TVS Diodes from the SMCJ series do not carry automotive industry certification but meet rigorous standards for discrete semiconductor components. These diodes are widely used in industrial controls, HVAC electronics, manufacturing equipment, and water treatment instrumentation to ensure reliable transient voltage protection and system durability.
