Overview
The Microsemi Corporation 1EZ160D2/TR12 is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 160 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 1 W and utilizes a DO-204AL (DO-41) axial-leaded plastic package suitable for through-hole mounting. It operates within a temperature range of -65°C to 150°C and includes a forward voltage of 1.2 V at 200 mA.
Feature Summary
- Provides precise voltage regulation with a 160 V nominal rating and ±2% tolerance.
- Constructed in a durable DO-204AL plastic encapsulated axial-leaded package.
- Capable of operating at high DC currents or full power ratings with adequate heat sinking.
Applications
- Voltage regulation circuits requiring stable reference levels.
- Protection against over-voltage conditions in electronic systems.
- Clamping applications in signal processing paths.
Procurement Notes
Verify the specific suffix 'TR12' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status, as standard versions may differ from lead-free variants. Ensure the supplier provides official datasheets matching the Microsemi part number to validate electrical characteristics before procurement.
Selection Notes
Select this component when a 160 V Zener voltage with high precision is required. The 1 W power rating dictates thermal management considerations for continuous operation. Compare against other series like 2EZ for higher power needs or 1N59xx for glass-encapsulated alternatives if hermetic sealing is necessary.
Part Context
This part belongs to the 1EZ series of 1 Watt Zener Diodes manufactured by Microsemi. The series offers various voltage selections from 110 to 200 volts in a DO-41 plastic package. Different suffixes indicate varying voltage tolerances, with 'D2' specifying the tighter ±2% tolerance option compared to standard commercial grades.
Replacement Considerations
Equivalent parts include the 1EZ160D5 for 5% tolerance or 1EZ160D1 for 1% tolerance. For higher power requirements, consider the 2EZ160 series. Glass-encapsulated equivalents are available in the 1N59xx series, such as 1N5948B, though package materials differ.
