Overview
The Microchip Technology 1N3024B-1E3/TR is a 1-watt glass case Zener diode with a nominal voltage of 15 volts and a 5% tolerance. It operates within a temperature range of -55°C to +175°C. The device features a maximum reverse leakage current of 10 µA at 11.4 V, a dynamic impedance of 14 ohms at 17 mA, and a maximum forward voltage of 1.2 V at 200 mA. It utilizes a DO-41 through-hole package and is qualified per MIL-PRF-19500/115.
Feature Summary
- Hermetically sealed glass construction for high-reliability environments
- Qualified under JAN, JANTX, and JANTXV military standards
- Inherently radiation hard design
- Low reverse leakage currents
Applications
- Voltage regulation over broad operating ranges
- High-reliability electronic circuits
- Radiation-hardened applications
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm RoHS compliance status and packaging configuration. Ensure the procurement specification matches the required military qualification level (JAN, JANTX, or JANTXV) as commercial versions may differ in reliability ratings and material composition.
Selection Notes
Select this component when a 15-volt reference with tight 5% tolerance is required in a through-hole glass package. Consider the 1-watt power dissipation limit and the -55°C to +175°C operating range for thermal management. Verify that the 14-ohm dynamic impedance meets the circuit's stability requirements.
Part Context
This part belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt Zener diodes. The series provides a wide selection of voltages from 6.8 to 110 volts in the same hermetically sealed DO-41 glass package. It is designed for applications requiring robust performance and long-term stability.
Replacement Considerations
Compatible substitutes include other 15V 1W Zener diodes in the DO-41 package with equivalent electrical characteristics. Verify that any replacement meets the specific MIL-PRF-19500/115 qualification level if military-grade reliability is mandated by the design.
