1SMA4735 技术参数

生命周期：	Contact Manufacturer	Reach Compliance Code：	unknown
风险等级：	5.79	Base Number Matches：	1

NOTE:

1. Tolerance and Type Number Designation. The type umbers listed have a standard tolerance on the nominal zener

voltage of + 5%

2. Specials Available Include:

A. Nominal zener voltages between the voltages shown and tighter voltage tolerances.

B. Matched sets.

3. Zener Voltage (Vz) Measurement. Guarantees the zener voltage when measured at 90 seconds while maintaining

the lead temperature (TL

) at 30 ^oC + 1 ^oC, from the diode body.

4. Zener Impedance (Zz) 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 (Izt or Izk) is superimposed on Izt or Izk.

5. Surge Current (Ir) Non-Repetitive. The rating listed in the electrical characteristics table is maximum peak,

non-repetitive, reverse surge current of 1/2
