1N3030C-1

Overview

The Microchip Technology 1N3030C-1 is a 27 V Zener diode with a 2% voltage tolerance, housed in a hermetically sealed DO-41 glass package. It supports a maximum DC power dissipation of 1 W and operates within a junction temperature range of -55°C to +175°C. The device features a test current of 9.5 mA, a maximum reverse leakage current of 10 µA at 20.6 V, and a dynamic impedance of 35 Ohms at the test point.

Feature Summary

• Hermetically sealed glass construction for high-reliability environments
• Dual plug metallurgically bonded design
• Low reverse leakage currents
• Inherently radiation hard

Applications

• Voltage regulation over broad operating current and temperature ranges
• High-reliability military applications requiring JAN, JANTX, or JANTXV qualifications
• ESD non-sensitive circuit protection

Procurement Notes

Verify that the specific ordering suffix matches the required reliability level (JAN, JANTX, JANTXV) and RoHS compliance status. Confirm the package type corresponds to the DO-41 through-hole configuration. Ensure the voltage tolerance designation aligns with the 'C' suffix indicating 2% accuracy before finalizing procurement orders.

Selection Notes

Select this component when a precise 27 V reference is needed with tight 2% tolerance. The DO-41 glass package provides superior thermal stability compared to plastic alternatives. Consider the 1 W power rating and derating curves for high-temperature environments. Verify compatibility with existing PCB footprints designed for standard axial leaded components.

Part Context

This part belongs to the established 1N3016B-1 through 1N3045B-1 series of 1 Watt Glass Case Zener Diodes. The series offers a wide selection from 6.8 to 110 volts. It is qualified per MIL-PRF-19500/115 standards. The 'C' suffix specifically denotes the 2% voltage tolerance variant within the JEDEC registered numbering system.

Replacement Considerations

Direct substitutes include other manufacturers' 1N3030 equivalents meeting MIL-PRF-19500/115 specifications. Verify that replacement parts maintain the same DO-41 package dimensions and hermetic sealing requirements. Cross-reference electrical parameters such as Zener impedance and leakage current to ensure functional parity.
