•Wide Zener Reverse Voltage Range − 2.4 V to 110 V

•Package Designed for Optimal Automated Board Assembly

•Small Package Size for High Density Applications

•General Purpose, Medium Current

•ESD Rating of Class 3 (> 16 kV) per Human Body Model

•SZ Prefix for Automotive and Other Applications Requiring Unique

Site and Control Change Requirements; AEC−Q101 Qualified and

PPAP Capable

•These are Pb−Free Devices*

Mechanical Characteristics:

CASE: Void-free, transfer-molded, thermosetting plastic case

FINISH: Corrosion resistant finish, easily solderable

MAXIMUM CASE TEMPERATURE FOR SOLDERING PURPOSES:

Stresses exceeding Maximum Ratings may damage the device. Maximum

Ratings are stress ratings only. Functional operation above the Recommended

Operating Conditions is not implied. Extended exposure to stresses above the

Recommended Operating Conditions may affect device reliability.

1. FR−5 = 3.5 X 1.5 inches, using the minimum recommended footprint.

2. Thermal Resistance measurement obtained via infrared Scan Method.

3. “B” Suffix Type numbers shown have a standard tolerance of ±5% on the nominal Zener voltages.

4. Nominal Zener voltage is measured with the device junction in thermal equilibrium at TL = 30°C ±1°C.

5. ZZT and ZZK are measured by dividing the AC voltage drop across the device by the ac current applied.

The specified limits are for IZ(AC) = 0.1 IZ(dc) with the AC frequency = 1 kHz.

*Include SZ-prefix devices where applicable.
