Littelfuse 1.5 kW Bi-Directional TVS Diode, Surface Mount, 2-Pin DO-214 SMCJ15CA

Littelfuse SMCJ15CA is a bi-directional Transient Voltage Suppression (TVS) diode engineered to protect sensitive electronics from voltage surges and transient events. This diode is designed for surface mount applications using the DO-214 package, offering compact integration and efficient board space utilization. With a peak pulse power dissipation of 1.5 kW and a clamping voltage of 24.4 V, it provides robust protection against both positive and negative transient voltages.

The SMCJ15CA features a minimum breakdown voltage of 16.7 V with a reverse stand-off voltage rating of 15 V. The device's fast response time, typically less than 1.0 picoseconds, ensures immediate reaction to surge events. Its low incremental surge resistance and glass passivated junction make it highly reliable for industrial and commercial electronics subject to unpredictable voltage spikes.

This TVS diode supports high current protection with a peak pulse current reaching up to 61.5 A and remains effective across a wide temperature range from -65°C to 150°C. Its surface mount format and 2-pin configuration allow for easy automated placement in high-volume manufacturing. The SMCJ15CA belongs to the Littelfuse SMCJ series, known for built-in strain relief, low inductance, and excellent clamping capability, making it suitable for demanding environments, including lightning and ESD events.

Applications of the SMCJ15CA include industrial controllers, commercial electronic systems, telecommunication interfaces, computer peripherals, and laboratory electronics where over-voltage protection is critical. The halogen-free construction and typical high temperature soldering capability (250°C for 10 seconds at terminals) further enhance its compatibility with rigorous industrial standards.

Key technical parameters include surface mount configuration, single element per chip, DO-214 package, 2-pin count, and minimal reverse leakage current (1 µA max). The SMCJ15CA is compliant with quality and environmental standards and is manufactured in China. This product is ideal for professionals in electronics, industrial automation, laboratory instrumentation, and PCB design fields seeking reliable, high-performance TVS diode solutions.
