Overview
The Microchip Technology 1N5284/TR is a field-effect current regulator diode designed for surface mount and axial applications. It provides a regulated current of 264 µA with a maximum anode-to-cathode voltage rating of 100V. The device features a power dissipation capacity of 500 mW, ensuring stable operation under specified thermal conditions. Available in packages such as DO-204AA (DO-7) and DO-213AB-2, it utilizes Tape & Reel or Bulk packaging options to facilitate automated assembly processes.
Feature Summary
- Provides constant current regulation independent of voltage fluctuations
- Utilizes field-effect technology for stable performance
- Available in standard axial and SMD package formats
Applications
- Constant current sources for LED driving circuits
- Biasing elements for transistor amplifier stages
- Current limiting protection in electronic circuits
Procurement Notes
Verify the specific package variant required, as the 1N5284 series is available in both axial DO-204AA and surface mount DO-213AB-2 configurations. Confirm RoHS compliance status, as some variants may be non-compliant. Ensure the ordering suffix matches the desired tape and reel or bulk packaging format to align with manufacturing requirements.
Selection Notes
Select this component when a fixed current source is needed without complex circuitry. The 264 µA output is suitable for low-power biasing applications. Consider the 100V breakdown voltage for high-voltage environments. Evaluate thermal management needs based on the 500 mW power rating and ensure the chosen package style fits the PCB layout constraints.
Part Context
This part belongs to the 1N5284 family of current regulator diodes manufactured by Microchip Technology. These devices are discrete semiconductors categorized under diodes and rectifiers. The 1N5284/TR specifically denotes the tape and reel version of the axial package variant, distinct from the JAN1N5284UR-1 which uses a different SMT package.
Replacement Considerations
- 1N5284/TR PBFREE (Central Semiconductor)
- JAN1N5284UR-1 (Microchip, DO-213AB-2 package)
FAQ
What is the regulated current value of the 1N5284/TR?
The device regulates a current of 264 µA.
Does the 1N5284/TR support surface mount installation?
Yes, while the TR suffix typically indicates the axial DO-204AA package in tape and reel, the broader 1N5284 family includes surface mount variants like the JAN1N5284UR-1 in DO-213AB-2.
