Overview
The Microchip Technology 1N2970C is a 10W Zener diode with a nominal voltage of 6.8V at a test current of 370mA. It features a maximum dynamic impedance of 1.2 Ohms and a temperature coefficient of +0.057%/°C. The device operates within a junction temperature range of -65°C to +175°C, dissipating up to 10W at a case temperature of +55°C. It utilizes a DO-4 (DO-213AA) stud mount package with standard anode-to-stud polarity.
Feature Summary
- Hermetically sealed welded metal and glass construction for environmental protection.
- Internal solder bond construction ensuring mechanical stability.
- Qualified per MIL-PRF-19500/124 for JAN, JANTX, and JANTXV military grades.
- Inherently radiation hard design suitable for harsh environments.
Applications
- Voltage regulation over broad current and temperature ranges.
- Military and aerospace electronic systems requiring high reliability.
- Radiation-hardened circuit protection applications.
Procurement Notes
Verify the specific suffix configuration against the datasheet nomenclature. The 'C' designation indicates a 5% tolerance level. Confirm whether the required grade is JAN, JANTX, or JANTXV, as these are distinct qualification levels. Ensure the polarity matches the standard anode-to-stud configuration unless a reverse polarity variant is explicitly specified in the order details.
Selection Notes
Select this component when a 10W power rating and stud-mount form factor are required. The 6.8V breakdown voltage suits low-voltage reference circuits. Consider the positive temperature coefficient for thermal compensation needs. Verify that the mounting hardware accommodates the 10-32 thread size and hex dimensions specified in the mechanical data.
Part Context
This part belongs to the 1N2970B through 1N3015B series of 10W Zener diodes manufactured by Microsemi (now Microchip). These devices are JEDEC registered and designed for high-reliability applications. The series covers voltages from 3.9V to 200V, offering standardized performance across various military qualification levels.
Replacement Considerations
Direct substitutes include other 1N2970B variants with matching voltage and tolerance. Equivalent parts must support the DO-4 stud package and 10W dissipation. Verify that any replacement meets the same MIL-PRF-19500/124 qualification requirements if military-grade reliability is necessary.
