1N3830A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3830A-1/TR is a 7.5 V Zener diode housed in a hermetically sealed DO-13 metal case. It operates with a test current of 34 mA and features a maximum impedance of 1.5 Ohms at the test point, rising to 1.5 Ohms at 1 mA. The device supports a maximum Zener current of 250 mA and exhibits a typical temperature coefficient of +0.057 %/°C. It dissipates up to 1 Watt of power within an operating junction and storage temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed welded metal and glass construction for high-reliability environments
• Inherently radiation hard design suitable for demanding applications
• Internally solder-bonded construction ensuring mechanical stability

Single Zener Diodes Applications

• High-reliability voltage regulation circuits
• Military and aerospace electronic systems
• Radiation-hardened circuit protection

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required military qualification level (JAN, JANTX, or JANTXV) if screening per MIL-PRF19500/115 is necessary. Confirm the presence of the e3 suffix for RoHS compliance regarding annealed matte-Tin plating. Ensure the TR suffix is present to verify Tape & Reel packaging per EIA-296 standards rather than bulk or tray formats.

Single Zener Diodes Selection Notes

Select this component when a low-voltage reference between 3.3 V and 7.5 V is required in a ruggedized metal package. The 1N3830A variant specifically provides a nominal 7.5 V breakdown with tight tolerance characteristics. Consider the thermal resistance specifications and mounting methods to ensure adequate heat dissipation for continuous 1 Watt operation.

Single Zener Diodes Part Context

This part belongs to the established 1N3821 through 1N3830A series registered under JEDEC standards. It shares the same DO-13 (DO-202AA) package form factor as other low-voltage Zener diodes in the lineup. The series is designed to provide a comprehensive selection of voltages from 3.3 V to 7.5 V in a single hermetically sealed metal case style.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' equivalents meeting the 1N3830A specification in a DO-13 package. For higher voltage requirements within the same package, the 1N3016 through 1N3051 series may be considered. Surface mount alternatives exist in the 1N3821UR-1 through 1N30330AUR-1 series.
