Overview
The Microchip Technology 2N5539 is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 19 V with a tolerance of 5%. The device operates at a test current of 1 mA and exhibits a maximum reverse leakage current of 10 nA. It has a power dissipation rating of 500 mW and a Zener impedance of 100 Ohms. The component supports through-hole mounting in a DO-204AH-2 package, with an operating temperature range from -65 °C to +175 °C.
Feature Summary
- Provides stable voltage regulation with a 19 V nominal breakdown voltage.
- Capable of operation across a wide industrial temperature range up to 175 °C.
- Features low reverse leakage current for efficient standby performance.
Applications
- Voltage reference circuits
- Overvoltage protection
- Biasing networks
Procurement Notes
Verify the specific suffix codes against official datasheets to confirm package type and tolerance levels. Ensure that the required operating temperature range aligns with the component's specified limits. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference manufacturer part numbers to avoid confusion with similar series variants.
Selection Notes
Select this component when a precise 19 V reference is required in through-hole designs. Consider the 500 mW power dissipation limit during thermal analysis. Evaluate the 100 Ohm impedance for high-frequency noise sensitivity. Compare the -65 °C to +175 °C range against environmental constraints to ensure reliability under extreme conditions.
Part Context
This component belongs to the standard Zener diode family manufactured by Microchip Technology. It utilizes axial lead construction suitable for general-purpose circuit boards. The device serves as a fundamental passive element for establishing fixed potential points within electronic systems. Its specifications align with common industry standards for voltage regulation tasks.
Replacement Considerations
Substitutes must match the 19 V Zener voltage, 500 mW power rating, and DO-204AH-2 package dimensions. Verify equivalent electrical characteristics such as impedance and leakage current. Ensure the replacement supports the same operating temperature range and mounting style.
