Low Noise Zener Diode Series 1N4099-1 thru 1N4135-1 and 1N4614-1 thru 1N4627-1 Datasheet

Category: Aeroflex Metelics, Diodes, Electronics

Overview

The datasheet provides details on the Low Noise Zener Diode Series including 1N4099-1 through 1N4135-1 and 1N4614-1 through 1N4627-1. These diodes are designed for applications that require low noise performance and come in a hermetically sealed, axial-leaded glass DO-35 package. They are also available in a DO-213 MELF style package.

Features

The series features diodes that are available with various military standards: JAN, JANTX, JANTXV, and JANS per MIL-PRF-19500/435. Certain models in the series offer tight tolerance levels for nominal Zener voltage, at plus or minus 20% with a ‘C’ suffix and at plus or minus 1% with a ‘D’ suffix. These diodes are capable of handling power up to 500 mW and are suitable for operating within a broad temperature range from -65 to +175 degrees Celsius.

Maximum Ratings and Electrical Specifications

Maximum Ratings: The diodes have a maximum thermal resistance of 250°C/W and can operate at steady-state power of 0.5 watts. They also have a forward voltage of 1.1 volts when a current of 200 mA is applied.

Electrical Specifications: At 25 degrees Celsius, specifications such as normal Zener voltage, test current, maximum reverse current, noise density, and maximum Zener impedance are outlined for each diode type, providing detailed information for circuit design and component selection.

Technical Table

A table lists individual diode types with their respective JEDEC numbers and key parameters such as normal Zener voltage (Vz), test current (IzT), Zener impedance (ZzT), reverse current (IR), noise density (ND), and the maximum Zener current (IzM). These specifications vary across the diode series to accommodate different circuit requirements.

Standard Tolerance and Measurement Conditions

It is noted that diodes with no suffix have a standard tolerance of ±5% on the nominal Zener voltage. The suffix ‘C’ denotes a ±20% tolerance, and the suffix ‘D’ indicates a ±1% tolerance. Measurements for Vz are conducted with the diode in thermal equilibrium within an ambient temperature of 25 degrees Celsius.

The datasheet revision date is indicated as November 4, 2009, and this is specified as a new product release at that time.
