Overview
The Microsemi Corporation 1EZ190D2E3/TR12 is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 190 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 1 W and utilizes the DO-204AL (DO-41) axial leaded plastic package. This component supports through-hole mounting and operates within a junction temperature range of -65°C to 150°C.
Feature Summary
- Provides precise voltage regulation with a tight ±2% tolerance on the 190 V nominal rating.
- Constructed in a durable plastic DO-204AL (DO-41) axial leaded package suitable for standard through-hole mounting.
- Capable of operating reliably across an extended industrial temperature range from -65°C to 150°C.
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection stages in electronic systems
- General-purpose voltage regulation tasks
Procurement Notes
Verify that the specific suffix 'e3' confirms RoHS compliance, as this indicates a lead-free finish compared to non-compliant variants. Confirm the 'TR12' designation matches the required tape-and-reel packaging format for automated assembly processes. Ensure the ±2% tolerance requirement aligns with the design specifications before procurement.
Selection Notes
Select this component when a 190 V regulation point is required with high precision. The ±2% tolerance distinguishes it from standard 5% or 10% variants. Consider the 1 W power rating and thermal management requirements for the DO-204AL package. Verify compatibility with existing through-hole manufacturing lines.
Part Context
This part belongs to the Microsemi 1EZ series of 1-watt silicon Zener diodes. The series offers a wide selection of voltages and tolerances. The 'e3' suffix denotes environmental compliance, while the 'D2' indicates the specific 2% tolerance class within the product family.
Replacement Considerations
Compatible replacements include other 190 V Zener diodes with ±2% tolerance and 1 W power ratings in the DO-204AL package. Verify electrical parameters such as impedance and leakage current match the original design requirements.
