SMBJ4729CE3/TR13

The SMBJ4729CE3/TR13 is a single Zener Diode designed to protect sensitive circuits such as implantable medical devices or handhelds. It offers overvoltage protection, EMI/RFI filtering, and other circuit protection functions. It is primarily used in the protection of microcontrollers, field-programmable gate arrays, and other micro-level circuitry. This diode is available in lead-free versions and offers excellent thermal stability.

The SMBJ4729CE3/TR13 Zener Diode has a maximum forward breakdown voltage rating of 47 volts, and a maximum reverse breakdown voltage of 29 volts. The power dissipation rating for this diode is 300 mW, and its nominal capacitance is 3.2 pF. It has a maximum operating temperature of 125°C and a maximum storage temperature of 150°C.

The SMBJ4729CE3/TR13 has a wide range of applications, including consumer electronics, automotive applications, industrial control systems, personal computers and peripherals, and medical equipment. It can be used as a voltage regulator, current stabilizer, EMI filter, and for surge protection. It is also well suited for use in wifi systems, radio-frequency circuits and amplifiers, power supply design, and other high-frequency applications.

The working principle of the SMBJ4729CE3/TR13 is based on a Zener diode’s reverse breakdown voltage. When a voltage greater than the device’s Zener breakdown voltage is applied, the diode begins to conduct current in the reverse direction. This phenomenon is known as Zener breakdown. The reverse current is limited, however, by the diode’s reverse leakage current characteristics. The SMBJ4729CE3/TR13 is designed to shield the sensitive circuits it protects from voltage transients by clamped the transient to the Zener breakdown voltage.

In summary, the SMBJ4729CE3/TR13 is a single Zener Diode designed to protect sensitive circuits such as implantable medical devices or handhelds. It offers overvoltage protection, EMI/RFI filtering, and other circuit protection functions. Its wide range of applications include consumer electronics, automotive applications, industrial control systems, personal computers and peripherals, and medical equipment. The working principle of the SMBJ4729CE3/TR13 is based on Zener breakdown voltage, which clamps transient voltage to the Zener breakdown voltage.
