ZENER DIODES
DESCRIPTION
NEC Type RD2.0E to RD200E Series are planar type zener diode in the
popular DO-35 package with DHD (Double Heatsink Diode) construction
having allowable power dissipation of 500 mW. To meet various application
at customers, V
z
(zener voltage) is classified into the tight tolerance under
the specific suffix (B, B1 to B7).
