STMicroelectronics 1-Element Bi-Directional TVS Diode 400 W 2-Pin DO-214 SMAJ6.5CA-TR

STMicroelectronics SMAJ6.5CA-TR is a 1-element bi-directional transient voltage suppression (TVS) diode engineered for protecting sensitive electronic components from voltage spikes and transient surges. With a robust peak pulse power rating of 400 W, this surface mount TVS diode is ideal for industrial, electronic, and power protection applications requiring reliable, long-term surge immunity.

Featuring a compact DO-214 2-pin package, the diode configuration is single and the device provides bi-directional voltage clamping to efficiently guard against both positive and negative transient events. Its key electrical characteristics include a minimum breakdown voltage of 7.2 V and a clamping voltage of 14.5 V, making it suitable for protecting low-voltage circuits but capable of sustaining high transient energy.

The SMAJ6.5CA-TR can operate in harsh conditions with an operating temperature range from -55°C up to 150°C, ensuring performance stability in demanding environments. Its maximum peak pulse current of 160 A ensures superior protection against short-duration high current spikes, which are common in industrial, automotive, and communication devices.

The device’s small dimensions of 4.6 mm length, 2.9 mm width, and 2.45 mm height allow it to be incorporated into compact PCB designs without sacrificing performance. The low maximum reverse leakage current of 50 μA enhances energy efficiency and prevents unnecessary power dissipation during normal operation.

This transient voltage suppressor diode from STMicroelectronics is widely used in power supply lines, I/O ports, and other sensitive electronic interface circuits for protecting against ESD, lightning-induced surges, or other transient voltages. Its surface mount design facilitates automated assembly and improves manufacturing efficiency.

The diode configuration is single, providing reliable transient voltage suppression. Operates bidirectionally with a peak pulse power dissipation of 400 W. Features a DO-214 package type with 2 pins for easy surface mounting.
