Category: Aeroflex Metelics, Diodes, Electronics

Overview

This datasheet provides information on the Low Noise Zener Diode Series, which comprises models ranging from 1N4099-1 to 1N4135-1 and 1N4614-1 to 1N4627-1. These diodes are designed for performance with a low noise feature, and they come in JAN, JANTX, JANTXV, and JANS quality levels as per the MIL-PRF-19500/435 specification. They are suitable for precision electronics due to their tight voltage tolerances of ±20% or ±1% with C or D suffixes, respectively. These diodes can handle 500 mW of steady-state power and are encapsulated in a hermetically sealed, axial-leaded glass DO-35 package, with an alternative DO-213 MELF style package available.

Maximum Ratings and Electrical Specifications

The datasheet outlines the maximum operating and storage temperature range for these diodes, established between -65°C and +175°C, and the thermal resistance of 250°C/W. The forward voltage is specified at 1.1V when conducting 200 mA. Moreover, the Zener voltage range, test current, Zener impedance, reverse leakage current, and noise density are listed for different diode types under normal conditions at +25°C.
