Speciﬁcations Subject to Change Without Notice.

Electrical Speciﬁcations @ 25°C

Breakdown Voltage @ I

R = 10 µA, VB = 12 Volts Minimum

Reverse Leakage Current @ V

R = 10 Volts, IR = 100 nA Maximum

Temperature Coefﬁcient ot Capacitance @ V

R = 8 Volts, TCC = 400 ppm/°C Typical

Ordering Information

The part numbers shown are for single diodes. When

ordering diodes in common cathode pairs add suffix

“CK.” For example, MA4ST079CK speciﬁes model num-

ber MA4ST079 as a common cathode pair. To order parts

on tape and reel add sufﬁx T/R to the end of the part

number. i.e. MA4ST079-T/R
