MMBZxxxALT1G Series, SZMMBZxxxALT1G Series
Zener Diodes, 24 and 40 Watt Peak Power
SOT−23 Dual Common Anode Zeners
These dual monolithic silicon Zener diodes are designed for applications requiring transient overvoltage protection capability. They are intended for use in voltage and ESD sensitive equipment such as computers, printers, business machines, communication systems, medical equipment and other applications. Their dual junction common anode design protects two separate lines using only one package. These devices are ideal for situations where board space is at a premium.
Features
• SOT−23 Package Allows Either Two Separate Unidirectional
Configurations or a Single Bidirectional Configuration
• Standard Zener Breakdown Voltage Range − 5.6 V to 47 V • Peak Power − 24 or 40 W @ 1.0 ms (Unidirectional),
per Figure 6 Waveform
• ESD Rating:
− Class 3B (> 16 kV) per the Human Body Model − Class C (> 400 V) per the Machine Model
• ESD Rating of IEC61000−4−2 Level 4, ±30 kV Contact Discharge • Maximum Clamping Voltage @ Peak Pulse Current • Low Leakage < 5.0 mA • Flammability Rating UL 94 V−0 • SZ Prefix for Automotive and Other Applications Requiring Unique
Site and Control Change Requirements; AEC−Q101 Qualified and PPAP Capable
• These Devices are Pb−Free and are RoHS Compliant
