1N2979C PBFREE

Overview

The Central Semiconductor Corp 1N2979C PBFREE is a silicon Zener diode housed in a hermetically sealed metal DO-4 package. It provides a nominal reference voltage of 15 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 10 W and operates at a test current of 170 mA. Designed for high-reliability applications, it features a maximum dynamic impedance of 3 Ω and supports operating temperatures up to 175 °C.

Feature Summary

Hermetically sealed metal case construction for environmental protection
High precision voltage regulation with ±2% tolerance
Capable of handling high power dissipation up to 10 W

Applications

Precision voltage reference circuits
High-reliability power supply regulation
Military and aerospace electronic systems

Procurement Notes

Verify component authenticity due to potential availability issues. Confirm RoHS compliance status as the part may be obsolete or subject to specific manufacturing lot variations. Check for parametric equivalents if direct procurement is unavailable. Ensure the supplier provides valid traceability documentation for hermetically sealed components.

Selection Notes

Select this component when strict voltage accuracy and thermal stability are required in harsh environments. The DO-4 metal package offers superior heat dissipation compared to plastic alternatives. Consider the ±2% tolerance requirement against standard 5% or 10% Zener options. Evaluate the 170 mA test current requirement against circuit biasing capabilities.

Part Context

This part belongs to the 1N2979 series of high-power Zener diodes manufactured by Central Semiconductor. The series is characterized by its use in ruggedized electronics where long-term stability and resistance to environmental stressors are critical. The hermetic seal distinguishes it from commercial-grade plastic-packaged counterparts.
