Overview
The Microchip Technology 1N2836B is a high-power silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 82 V with a maximum impedance of 9 Ohms. The device supports a maximum power dissipation of 50 W and operates within a temperature range of -65°C to 175°C. Qualified per MIL-PRF-19500/114, it is available in JAN, JANTX, and JANTXV levels.
Feature Summary
- Provides stable voltage regulation across a broad range of values from 3.9 V to 200 V
- Capable of operating up to 50 W with adequate mounting and heat sinking
- Qualified for military standards including JAN, JANTX, and JANTXV levels
Applications
- High-power voltage regulation circuits
- Military electronic systems requiring qualified components
- Industrial equipment needing robust overvoltage protection
Procurement Notes
Verify the specific qualification level (JAN, JANTX, or JANTXV) required for your application, as these levels may have distinct manufacturing specifications. Confirm that the ordering suffix matches the desired reliability grade. Ensure thermal management solutions are compatible with the 50 W power dissipation rating during system integration.
Selection Notes
Select this component when a high-power Zener diode with an 82 V breakdown voltage is required. Ensure the circuit design accommodates the 9 Ohm maximum impedance and the TO-204AD package constraints. Verify that the operating environment stays within the specified -65°C to 175°C temperature range for reliable performance.
Part Context
This part belongs to the 1N2804B through 1N2846B series of 50 Watt Zener diodes manufactured by Microchip Technology. These devices are JEDEC registered and offer a wide selection of voltage values. The series is specifically engineered for high-power applications where standard low-power diodes would fail due to thermal limitations.
Replacement Considerations
Compatible substitutes include other 50 W Zener diodes with an 82 V nominal voltage and similar TO-204AD packaging. Verify that any replacement meets the same MIL-PRF-19500/114 qualification requirements if military-grade reliability is necessary.
