SMD Zener Diodes ZISMA Series Overview

The ZISMA Series from Diotec Semiconductor AG are surface-mounted Zener diodes designed for applications requiring voltage stabilization and regulators, specifically in commercial-grade products. The ZISMA series is equipped with non-planar technology and offers a broad range of Zener voltages, making them suitable for various electronic circuits.

Key Features

High power dissipation: Ptot at Tt = 75°C is 1.5W
Vz specified at 5 mA, with a range up to 100 V
Operating junction temperature ranging from -50 to +150°C
Complies with RoHS, REACH, and Conflict Minerals standards
Standard Zener voltage tolerance is in line with the E24 international standard (approx. ±5%)
Available in various tolerances and higher Zener voltage options upon request
Supplied in tape and reel packaging, with a standard reel containing 7500 units

Electrical Characteristics

The ZISMA Series exhibit a low thermal resistance from the junction to ambient (RthA) at 70 K/W and to the terminal (RthT) at 30 K/W. A maximum forward voltage (VF) is specified at less than 1V under a forward current (IF) of 200 mA. Users should note that for ZISMA models, reference to parameters should use “F” for forward-mode operations. The diodes are also AEC-Q101 compliant (-Q suffix) or in qualification (-AQ suffix) for automotive standards.

Additional Specifications

Details regarding mechanical data, such as weight (approximately 0.07g) and case material UL 94V-0, along with solder and assembly conditions (260°C for 10s), are specified. The products are also provided with a SPICE Model & STEP File for simulation purposes.

Model Variants and Voltage Specifications

Models in the ZISMA series range from ZISMAL with a minimum Zener voltage (Vzmin) of 0.71V to ZISMA1OO with a maximum Zener voltage (Vzmax) of 106V. Items are marked with “Zxx” where “xx” represents the Vz value.
