STMicroelectronics 1-Element Bi-Directional TVS Diode 1.5 kW Surface Mount DO-214 SMCJ40CA-TR

The STMicroelectronics SMCJ40CA-TR is a high-performance 1-element bi-directional transient voltage suppression (TVS) diode designed to protect sensitive electronic components from voltage spikes and transients. It offers a peak pulse power dissipation of 1.5 kW and comes in a surface mount DO-214 package, making it suitable for integration on compact circuit boards.

This device is engineered with a single diode configuration that provides effective bi-directional protection with a minimum breakdown voltage of 44.4 V and a maximum reverse stand-off voltage of 40 V. The diode clamps transient voltages at 84 V, thereby preventing damage to the protected circuit from voltage surges.

Its robust electrical specifications include a maximum peak pulse current of 119 A and a very low maximum reverse leakage current of 200 nA, ensuring efficient protection without compromising energy efficiency. The broad operating temperature range from -55°C to 150°C allows for reliable use in harsh industrial, automotive, and commercial electronics environments.

The compact physical size of this DO-214 package (7.15 mm length x 6.25 mm width x 2.45 mm height) facilitates easy surface mounting on printed circuit boards, supporting automated manufacturing processes and saving board space.

Typical applications include protection in power supplies, voltage regulation circuits, and other semiconductor devices needing transient voltage suppression within electronics and electrical equipment. The device is part of the SMCJxxCA series widely adopted in industrial and commercial sectors for reliable surge protection.
