These glass axial-leaded DO-35 Zeners are also available with an internal-metallurgical-bond option by adding a -1 suffix. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

The Type Number indicates 5% Tolerance. (See Note 1.) NOTES: 1. Devices listed have a +/-5% voltage tolerance on nominal Vz with a B suffix. An A suffix is +/-10% and no suffix is +/-20%. Suffix C denotes a +/-2% tolerance and suffix D denotes a +/-1% tolerance. 2. All static parameters measured under pulsed conditions, tp = 300 s. 3. Dynamic Impedance is derived by measuring the ac voltage when superimposing an ac rms current of 0.2 mA at 1000 Hz on to the dc level of I .
