FAQ

How does the MAVR-046479-01340G generate harmonics?

It stores charge when driven to forward conductance by the positive voltage of the input signal. When the signal reverses polarity, the charge is extracted, causing the diode to snap to a higher impedance and form a voltage pulse in the impulse circuit.

What are the absolute maximum ratings for reverse voltage and power dissipation?

The absolute maximum reverse voltage is 30 V, and the maximum power dissipation is 250 mW at an ambient temperature of +25°C.

What is the recommended mounting procedure for this component?

Permanent attachment is performed by a reflow soldering procedure. The tab temperature must not exceed +275°C, and the body temperature must not exceed +260°C.
