1N4370ADO41

Single Zener Diodes Overview

The 1N4370ADO41 is a silicon Zener diode with a nominal voltage of 2.4 V and a maximum power dissipation of 500 mW. It features a DO-7 (DO-204AA) hermetically sealed glass axial-lead package. The 'A' suffix indicates a standard tolerance of ±5%, while the 'D' suffix specifies a tighter tolerance of ±1%. The device operates within a temperature range of -65°C to +175°C.

Single Zener Diodes Feature Summary

• Internally solder bonded for robust electrical connection
• Hermetically sealed glass DO-7 package construction
• Radiation hard design suitable for harsh environments
• ESD nonsensitive per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation over broad operating current ranges
• High-reliability aerospace and military circuits
• Temperature compensation networks
• Reference voltage sources in precision instrumentation

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes against the manufacturer datasheet to confirm tolerance levels and compliance options. Ensure the required screening level, such as JAN or JANTXV, is explicitly requested during procurement, as these require specific prefixes not included in the base part number.

Single Zener Diodes Selection Notes

Select this component when a tight ±1% voltage tolerance is required alongside high reliability standards. The DO-7 package provides a larger active die element compared to smaller packages, supporting higher thermal performance. Verify that the application environment does not exceed the specified maximum junction temperature or power dissipation limits.

Single Zener Diodes Part Context

This part belongs to the Microsemi 1N4370 series of 500 mW Zener diodes. The series covers voltages from 2.4 V to 12 V and includes various tolerance options identified by suffix letters. The DO-7 packaging variant offers straight-through soldered internal connections for enhanced durability in demanding applications.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N746A-1 and 1N746AUR-1. Verify pinout compatibility and ensure the replacement meets the same radiation hardness and hermetic sealing requirements if used in qualified systems.
