SMBJ6.5CA-E3/52

TVS (Transient Voltage Suppressor) diodes are a type of diode that provide protection from over-voltage transients in an electrical system. The SMBJ6.5CA-E3/52 is a TVS diode designed to protect sensitive electronic components that may encounter harmful transient voltage conditions. It is particularly well suited for protecting data lines, power supplies, and other sensitive components from voltage spikes.

Applications

The SMBJ6.5CA-E3/52 is designed to protect against lightning surges, electrostatic discharges, and over-voltage conditions in a range of applications. It can be used in automotive, telecommunications, consumer electronics, industrial control, and networking applications. It is also suitable for protecting AC adapter/charger inputs, or other areas where transient protection is needed.

The SMBJ6.5CA-E3/52 is designed with a wide range of operating parameters that allow it to provide effective protection in a range of voltage and current conditions. It can handle up to 6.5 Amps of forward current with a maximum pulse power of 1500 Watts. Its peak pulse power rating is 6.5 kV, while its clamping voltage is between 9.3 and 10.6 V. The diode also features a low capacitance of 4 pF, allowing it to operate in high frequency applications without causing interference.

Working Principle

The SMBJ6.5CA-E3/52 employs a Zener diode as its core component. This diode is made of a heavily doped PN junction which becomes conductive when a voltage is applied. The heavily doped junction causes the diode to break-down at a much lower voltage than a standard PN junction. As such, the diode can be used to regulate large over-voltage transients.

When a surge occurs, the diode will rapidly break down and clamp the voltage to its rated value. This prevents the current from exceeding the diode’s maximum current rating, protecting the downstream components from overvoltage transients.

The SMBJ6.5CA-E3/52 is an excellent choice for protecting sensitive equipment from transient voltage events. Its wide range of operating parameters allows it to effectively protect components in a variety of conditions.
