1N5994B

Single Zener Diodes Overview

The onsemi 1N5994B is a single silicon Zener diode with a nominal voltage of 5.6 V and a tolerance of 5%. It operates in the DO-35 (DO-204AH) axial leaded package, providing a maximum steady-state power dissipation of 0.5 W at temperatures up to 75°C. The device features a maximum dynamic impedance of 25 Ω and supports an operating temperature range from -65°C to +200°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass encapsulation for environmental protection
• Double slug construction with metallurgical bonding
• ESD rating of Class 3 (>6 kV) per Human Body Model

Single Zener Diodes Applications

• Voltage regulation circuits
• Reference voltage sources
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the manufacturer source carefully, as the 1N5994B designation is licensed by onsemi but manufactured by various entities including Tak Cheong. Confirm that the specific part number suffix matches the required JEDEC registration and hermetic sealing specifications. Ensure the component meets the intended thermal and electrical requirements before procurement.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, high-reliability Zener diode is required for harsh environments. The DO-35 package offers robust mechanical stability. Consider the 5.6 V nominal voltage and 0.5 W power rating to ensure compatibility with the circuit's voltage regulation and thermal dissipation needs.

Single Zener Diodes Part Context

This component belongs to the 1N59xxB series of axial-leaded Zener diodes. Licensed by onsemi, these devices utilize double slug construction for improved performance. The series covers a wide voltage range, typically from 2.4 V to 110 V, offering standardized reliability for industrial applications.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5994BRA1 and 1N5994BTA2. Verify that substitutes maintain the same DO-35 package, hermetic sealing, and 5.6 V / 0.5 W specifications.
