Frequently Asked Questions
What are the different voltage tolerances available for this series?
The ZM-Series is available in TZMC types with ±5% tolerance or TZMB types which offer tighter ±2% tolerance.
Are these diodes suitable for life-sustaining medical applications?
No, the products shown are not designed for use in medical, life-saving, or life-sustaining applications. Use is at customer's own risk.
What type of case and weight does the diode come in?
The component utilizes a MiniMELF glass case (SOD-80) and weighs approximately 31 mg.
What is the maximum junction temperature range for operation?
The specified storage temperature range is -65 to +175°C, and the junction temperature ($T_J$) must be considered during application use.
