<p>The DF2B29FU,H3F is a bidirectional Zener TVS (Transient Voltage Suppression) diode manufactured by Toshiba. It is designed to protect sensitive electronics from voltage transients. The device features a reverse standoff voltage of 24 V and a maximum clamping voltage of 47 V. It can handle a peak pulse current of 3 A (8/20 µs) and a peak pulse power of 140 W. The Zener technology ensures fast response to overvoltage events. This TVS diode is suitable for a variety of applications requiring circuit protection. It is a surface mount device in an SC-76 (SOD-323) package, with a USC supplier device package. The package is compact and suitable for space-constrained designs. The device has a typical capacitance of 9 pF at 1 MHz, which is low enough for high-speed signal lines. It is RoHS3 compliant and REACH unaffected. The bidirectional configuration allows protection of both polarities with a single component. Engineering considerations: The 24V standoff voltage ensures normal operation up to 24V without triggering. The clamping voltage of 47V limits the transient voltage safely. The 140W power rating at 8/20µs pulse defines the energy handling capability. The low capacitance makes it suitable for high-speed data lines such as USB, HDMI, etc. The surface mount package is compatible with standard reflow soldering processes.</p>
