STMicroelectronics 1-Element Uni-Directional TVS Diode 600 W, 2-Pin SMB SMB6F22A

STMicroelectronics SMB6F22A is a 1-element uni-directional transient voltage suppression (TVS) diode engineered to protect sensitive electronic components from voltage surges, spikes, and electrostatic discharges in industrial, electronic, automotive, and power applications.

This diode supports a peak pulse power dissipation of 600 W (with 10/1000 μs waveform) and an exceptional 4 kW rating at 8/20 μs, safeguarding equipment from transient voltage events.

The device features a low leakage current of 0.2 μA at room temperature (25 °C), increasing only slightly at higher temperatures, which ensures energy efficiency in high-end circuits that demand stability and longevity.

Compactly housed in a surface-mount SMB package (3.95 mm x 4.6 mm x 1.05 mm), it provides a flat and thin 1 mm profile suitable for densely packed circuit boards.

Operating temperature ranges from -55 °C to 175 °C, allowing stable performance under varying environmental conditions. The diode’s matte tin plating lead finish offers robust solderability and resistance to corrosion.

Electrical characteristics include a minimum breakdown voltage (Vbr) of 24.4 V, maximum reverse stand-off voltage (Vwm) of 22 V, clamping voltage (Vc) of 48.3 V, and a test current (It) of 1 mA, making it ideal for protecting power lines and signal lines within defined voltage limits.

The diode delivers a maximum peak pulse current (Ippm) of 83 A and incorporates electrostatic discharge (ESD) protection for reliable circuit safeguarding.

Its planar technology construction supports high junction temperatures and long-term operational reliability, fitting for applications in industrial electronics, manufacturing equipment, power supplies, and automotive electronics, where managing surge transients is critical.
