FEATURE
* Small surface mounting type. (SC-79/SOD-523)
* High temperature soldering type.
* ESD rating of class 3(>16 kV) per human body model.
* Silicon planar zener diodes.
* Silcon-oxide passivated junction.
* Low temperature coefficient voltage
* 500 mW Rating on FR-4 or FR-5 Board
MECHANICAL
* SC-79/SOD-523 Packaging.
* Cathode indicated by polarity band.
* Mounting position: Any.
1. The JEDEC type numbers listd have a standaerd tolerance on the normal zener voltage of +10%, Suffix B=+5%.
2. The zener impedance is derived from 1KHz AC voltage, which results when an AC current having an RMS value equal to 10%
3. Valid provided that electrodes at distance of 10mm from case are kept ambient temperature.
4. Measured under thermal equilibrium and DC test conditions.
5. The rating listd in the electrical characteristics table is maximum peak, non-repetitive, reverse surge current of 1/2 square wave
of DC zener current (I
on the breakdown curve to eliminate unstable units.
