Product Description

Bourns SMAJ7.0CA-Q is a bi-directional transient voltage suppressor (TVS) diode designed for protection against transient voltage surges, electrostatic discharge, and electrical overstress events. This diode supports up to 400 W peak pulse power dissipation, making it suitable for safeguarding sensitive electronic circuits in industrial, automotive, and consumer electronic applications.

Mounted in a surface-mount DO-214 AC (SMA) package, the device offers compact dimensions (2.54 mm length, 3.99 mm width, and 1.98 mm height) for space-constrained PCB layouts. It supports a standoff voltage range up to 220 V with a minimum breakdown voltage of 7.78 V, which ensures efficient suppression of voltage spikes within its specified limits.

This TVS diode features an exceptionally fast response time, under 1 picosecond, allowing it to react almost instantaneously to transient voltage events, thereby protecting components downstream in the circuit. The clamping voltage is rated at 12 V, which helps clamp voltage spikes to levels safe for other components.

Operating temperature ranges from -55°C to 150°C, making it robust for use in harsh environments, particularly automotive applications where it complies with the AEC-Q101 industry standard. It also adheres to RoHS compliance, ensuring it meets modern environmental and safety regulations.

The device provides an excellent solution for a variety of use cases encompassing industrial control systems, power supply lines, communication devices, and automotive electronic circuits that require reliable transient voltage suppression to prevent damage and ensure longevity.
