Electrical Characteristics

SMB(G or J)5333B thru SMB(G or J)5333B

Note 1 Devices listed have a 5% tolerance on nominal V Z.The suffix A denotes a 20% tolerance, suffix Cdenotes 2%, and suffix D denotes 1%.

Note 2 Nominal Zener Voltage (V Z) is read with the device instandard test clips with 3/8 to inch spacing betweenclip and case of the diode. Before reading, the diode isallowed so stabilize for a period of 40 10 millisecondsat 25C (+8, -2C).

Note 3 The Zener impedance (Z ZT or ZZK is derived from the 60HZ ac voltage, which results when an ac current havinga rms value equal to 10% of the dc zener current (I ZT orIZK) is superimposed on I ZT or IZK respectively. Dynamicimpedance variations with other current values aredescribed in Micronote 202.

Note 4 The Maximum Reverse (leakage) Current is specifiedfor devices with 20% and 10% voltage toleranceson nominal VZ in another column.

Note 5 The Maximum Zener Current (I ZM) shown is for 5%tolerance devices. I ZM for 10% and 20% devicescan be calculated using the formula:

IZM = P V ZM

Where VZM is VZ at the high end of the voltagetolerance specified and P is the rated power of thedevice.

Note 6 The Surge Current (I ZM) is specified as the maximumpeak of a nonrecurring sine wave of 8.3 millisecondsduration.

Note 7 Voltage Regulation (DVZ) is the difference between thevoltage measured at 10% and 50% I ZM).
