Littelfuse 1-Element Bi-Directional TVS Diode, 1.5 kW Peak Pulse Power, 2-Pin DO-214 Package SMCJ300CA

Littelfuse SMCJ300CA is a 1-element bi-directional TVS (Transient Voltage Suppressor) diode designed for effective transient voltage protection in electronic circuits. With a peak pulse power dissipation rating of 1.5 kW and a compact DO-214 surface mount package, it provides reliable suppression of voltage spikes to safeguard semiconductor devices and electrical components.

This diode features a single diode configuration operating bi-directionally, meaning it can clamp voltage transients in both directions of polarity. It has a minimum breakdown voltage (Vbr) of 335 V and a maximum reverse stand-off voltage (Vwm) of 300 V, suitable for medium voltage circuits. The clamping voltage is 486 V, defining the maximum allowable voltage during transient events.

The device supports a maximum peak pulse current (Ippm) of 3.1 A and includes ESD (Electrostatic Discharge) protection to mitigate damage from electrostatic events, enhancing longevity and reliability in harsh environments. The maximum reverse leakage current is low at 1 µA, reducing power dissipation during normal operation.

Designed for surface mount applications, the SMCJ300CA package measures 7.11 mm in length, 6.22 mm in width, and 2.417 mm in height with 2 pins for easy PCB integration. It operates safely across a broad temperature range from -65°C to +150°C, making it versatile for industrial, automotive, and power supply uses where transient voltages are common.

This TVS diode is part of the Littelfuse SMCJ series, known for consistent quality and durable protection solutions in the electronics industry. The device meets typical industrial surge suppression requirements though it is not certified for specific standards or automotive approvals.

The diode provides robust transient voltage suppression to protect discrete semiconductors and circuits. The compact DO-214 package supports easy surface-mount technology implementation. Wide operating temperature range ensures reliability in varied environments.

Low leakage current minimizes power loss and heat generation in normal operating conditions. ESD protection improves device tolerance to electrostatic events and handling.

Applications include industrial equipment power protection, automotive circuit transient suppression, power supplies, telecommunications, and other electronic systems requiring surge safeguarding. Choosing the SMCJ300CA offers engineered protection to prolong device life and maintain system stability.
