Product Description

Bourns SMF4L85A-Q is a high-performance 1-element uni-directional transient voltage suppressor (TVS) diode rated at 400 watts peak pulse power dissipation. Encased in a compact surface mount SOD-123 package, this diode safeguards sensitive electronic circuits from voltage transients caused by surges, spikes, or electrostatic discharge events.

Featuring a single diode configuration and a uni-directional voltage clamp, it provides reliable protection with a minimum breakdown voltage of 104 volts and a maximum reverse stand-off voltage of 85 volts. The clamping voltage is also rated at 85 volts, ensuring effective suppression of voltage spikes.

The device operates efficiently from -55°C up to 150°C, making it suitable for demanding industrial, automotive, and consumer electronics applications. Its minimal physical footprint (0.27mm length × 0.25mm width × 0.22mm height) allows integration in densely populated printed circuit boards while maintaining JEDEC compliance and AEC-Q101 automotive standard certification for demanding environments.

Bourns TVS diodes boast very fast response times of less than 1 picosecond, safeguarding circuits instantaneously against transient voltage events. The device’s low maximum reverse leakage current of just 1 microampere minimizes power dissipation in normal operation.

This diode is ideal for use in power supplies, telecom equipment, industrial controls, automotive electronics, and other applications requiring robust electrostatic and surge protection in a small form-factor package.
