1N3828A-1/TR

Single Zener Diodes Overview

The Microchip Technology 1N3828A-1/TR is a silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.2 V with a standard tolerance of ±5%. The device operates in the DO-41 axial leaded package and supports a maximum power dissipation of 1 W at an ambient temperature of 95°C. It is available in military-grade variants compliant with MIL-PRF-19500/115, offering tighter tolerances such as ±2% or ±1% depending on the specific suffix configuration.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-leaded construction for environmental protection
• Double plug construction with metallurgically bonded junctions
• Extended operating temperature range suitable for harsh environments

Single Zener Diodes Applications

• Precision voltage reference circuits
• Over-voltage protection stages
• Temperature compensated regulator designs

Single Zener Diodes Procurement Notes

Verify the exact suffix designation to confirm tolerance levels and compliance standards. Standard versions typically carry a ±5% tolerance, while JAN, JANTX, and JANTXV designations indicate adherence to MIL-PRF-19500/115 specifications with tighter tolerances. Confirm package type and testing requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable 6.2 V reference is required in a through-hole axial package. Consider the ±5% tolerance for general regulation or upgrade to C/D suffixes for precision applications requiring ±2% or ±1% accuracy. Ensure thermal management accounts for the 1 W dissipation limit and derating factors above 95°C.

Single Zener Diodes Part Context

This part belongs to the 1N3821A-1 through 1N3828A-1 series of silicon voltage regulators manufactured by Microchip Technology. The series provides various Zener voltages ranging from 3.3 V to higher values, all sharing the same 1 W power handling capability and DO-41 package form factor for interchangeability in legacy and new designs.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' 1N3828A equivalents meeting the same electrical specifications. For military specifications, verify compatibility with JAN1N3828A-1 or JANTXV1N3828A-1 variants which offer stricter quality controls and tighter voltage tolerances.
