Overview
The 1EZ100D10/TR8 is a silicon unidirectional Zener diode manufactured by Microsemi Corporation. It provides a nominal Zener voltage of 100 V with a tolerance of ±10%. The device is rated for a maximum power dissipation of 1 W and is housed in the DO-204AL (DO-41) axial leaded plastic package. This component is designed for voltage regulation applications requiring stable reference voltages within its specified operating temperature range.
Feature Summary
- Provides precise voltage regulation with a 10% tolerance on the 100 V nominal rating
- Engineered for high reliability in demanding environments using silicon technology
- Features a robust DO-204AL plastic encapsulation suitable for axial mounting
Applications
- Voltage reference circuits
- Overvoltage protection systems
- General-purpose voltage regulation
Procurement Notes
Verify the specific suffix TR8 to confirm tape and reel packaging requirements against your assembly line specifications. Confirm that the 10% tolerance aligns with your circuit design margins, as tighter tolerances require different suffixes. Ensure compatibility with the DO-204AL footprint and verify RoHS status if required by your manufacturing standards.
Selection Notes
Select this component when a 100 V reference with moderate precision is required. The 1 W power rating allows for adequate heat dissipation in standard through-hole layouts. Consider the 10% tolerance impact on circuit accuracy compared to tighter tolerance variants. Ensure the axial lead form factor fits the PCB layout constraints.
Part Context
This part belongs to the 1EZ series of Zener diodes from Microsemi, which are known for their use in military and aerospace applications. The series offers various voltage ratings and tolerance options. The 1EZ100D10 variant specifically targets the 100 V market segment with standard industrial tolerances.
Replacement Considerations
Check for direct equivalents such as the 1EZ100D2 or 1EZ100D5 if tighter voltage tolerances are acceptable. Verify pinout compatibility with the DO-204AL package before substitution.
