1. Standard Zener voltage tolerance is ±5% with a "B" suffix (e.g.: MMSZ5225B),suffix ''C'' is ± 2 % tolerance
.
2. Specials Available Include:
A. Nominal zener voltages between the voltages shown and tighter voltage tolerances.
B. Matched sets.
3. Zener Voltage (V
Z
) Measurement. Guarantees the zener voltage when measured at 90 seconds while maintaining the lead temperature (T
L
) at 30
O
C, from the diode body.
4. Zener Impedance (Z
Z
) Derivation. The zener impedance is derived from the 60 cycle ac voltage, which results when an AC current having an rms value equal to 10% of the dc zener
current (I
ZT
or I
ZK
) is superimposed on I
ZT
or I
ZK
.
5. Surge Current (I
R
) Non-Repetitive. The rating listed in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave or equivalent sine
wave pulse of 1/120 second duration superimposed on the test current, I
ZT
, per JEDEC registration; however, actual device capability is as described in Figure 5.

当今的计算机外部设备,都在追求高速度和高通用性。为了满足用户的需求,以Intel为首的七家公司于1994年推出了USB(Universal Serial Bus,通用串行总线)总线协议,专用于低、中速的计算机外设。目前,USB端口已成为微机主板的标准端口;而在不久的将来,所有的微机外设,包括键盘、鼠标、显示器、打印机、数字相机、扫描仪和游戏柄等等,都将通过USB与主机相连。
