JAN1N4462DUS

Single Zener Diodes Overview

The JAN1N4462DUS is a surface mount Zener voltage regulator qualified to MIL-PRF-19500/406. It features a voidless hermetically sealed glass package with an internal metallurgical bond. The nominal Zener voltage is 7.5 V with a 1% tolerance. Electrical characteristics at 25°C include a test current of 34.0 mA, maximum dynamic impedance of 2.5 Ohms, and maximum continuous current of 191 mA. Steady-state power dissipation is 1.5 W at 25°C ambient temperature.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless glass construction with tungsten slugs
• Internal Category 1 metallurgical bonds for enhanced reliability
• Triple-layer passivation for robust protection
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020

Single Zener Diodes Applications

• High-reliability military applications where failure cannot be tolerated
• Voltage regulation over broad operating current and temperature ranges
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'D' confirms the 1% tolerance level as defined in the part nomenclature section. Confirm that the device meets the required JANS or JAN qualification levels specified by the design. Ensure compatibility with the specified MELF surface mount footprint dimensions before integration.

Single Zener Diodes Selection Notes

Select this component when a 7.5 V reference with tight 1% tolerance is required in a surface mount form factor. Consider the 1.5 W steady-state power rating and thermal resistance values for heat dissipation planning. Verify that the operating temperature range of -65°C to +175°C aligns with the environmental conditions of the target application.

Single Zener Diodes Part Context

This device belongs to the 1N4460US through 1N4496US series of 1.5 Watt Zener diodes. It serves as the surface mount equivalent to the popular JEDEC registered axial lead series. The product line offers extensive voltage selections from 3.3 to 200 volts with various tolerance options available across different reliability levels.
