1SMF5920B

2.5 Watt Zener Diode in Flat

Lead Package

This complete new line of 2.5 Watt Zener Diodes are offered in

highly efficient micro miniature and space saving surface mount

design. Because of its small size, it is ideal for use in cellular phones,

portable devices, business machines and many other industrial/

consumer applications.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

3. Zener voltage is measured with the device junction in thermal equilibrium with an ambient temperature of 25°C.

4. Zener Impedance Derivation ZZT and ZZK are measured by dividing the AC voltage drop across the device by the AC current applied. The

specified limits are for IZ(ac) = 0.1 IZ(dc) with the ac frequency = 60 Hz.
