Overview
The Microchip Technology 1N3004A is a 10-watt Zener diode designed for voltage regulation and protection applications. It maintains a constant 91V output voltage with a tolerance of ±5%. The device operates at a test current of 28mA and exhibits an impedance of 35 Ohms. It utilizes a DO-213AA (DO-4) package, supporting chassis or stud mounting configurations for efficient thermal dissipation in high-power environments.
Feature Summary
- Provides stable voltage regulation at 91V nominal level
- Supports high power dissipation up to 10 watts
- Features robust chassis or stud mount construction
Applications
- Voltage regulation circuits
- Overvoltage protection systems
- Reference voltage sources
Procurement Notes
Verify the manufacturer origin, as the 1N3004A specification has been produced by multiple entities including Microchip, Microsemi, and others. Confirm the specific datasheet version matches your design requirements regarding thermal resistance and mechanical dimensions. Ensure the package type aligns with your mounting infrastructure before procurement.
Selection Notes
Select this component when a precise 91V reference is required in high-power scenarios. The stud-mount capability makes it suitable for direct attachment to heat sinks. Consider the ±5% tolerance for precision applications and verify that the 10W power rating meets the thermal management capabilities of the target system enclosure.
Part Context
This part belongs to the standard 1N300x series of high-power Zener diodes. Originally associated with Microsemi Corporation, production rights and manufacturing have shifted among various semiconductor manufacturers over time. The 1N3004A specifically denotes the 91V variant within this established regulatory family.
Replacement Considerations
Cross-reference with other manufacturers' 1N3004A equivalents such as those from New Jersey Semiconductor Products Inc. Verify pinout compatibility and thermal characteristics when substituting parts from different original equipment manufacturers.
