1N3005RB

Overview

The 1N3005RB is a single Zener diode manufactured by Microchip Technology, designed for high-power voltage regulation applications. It features a nominal Zener voltage of 100 V with a tolerance of ±5% and a power dissipation rating of 10 W. The device utilizes internal solder bond construction and is hermetically sealed via welding. It is housed in the DO-213AA package, which supports chassis or stud mounting. The component exhibits a maximum forward voltage of 1.5 V at a forward current of 2 A.

Feature Summary

• Hermetically sealed welded construction ensuring environmental stability
• Internal solder bond design for robust mechanical integrity
• High power handling capability suitable for chassis or stud mounting

Applications

• High-voltage regulation circuits requiring 10 W power dissipation
• Industrial equipment protection systems
• Military-grade electronic assemblies requiring hermetic sealing

Procurement Notes

Verify that the specific order matches the required MIL-PRF qualification level, as variants such as JAN, JANTX, and JANTXV exist within the series. Confirm the package type is DO-213AA for proper mounting compatibility. Ensure the Zener voltage tolerance aligns with circuit requirements, as this specific part is rated at ±5%. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a 100 V Zener voltage with 10 W power rating is necessary. The DO-213AA package requires thermal management solutions compatible with stud or chassis mounting. Consider the hermetic seal requirement for harsh environments. Verify that the ±5% tolerance meets the precision needs of the voltage reference application compared to wider tolerance alternatives.

Part Context

This component belongs to the 1N3005 series of single Zener diodes produced by Microchip Technology. The series covers a range of Zener voltages from 3.9 V to 200 V. The 1N3005RB specifically denotes the 100 V variant within this lineup, sharing common construction features like hermetic sealing and internal solder bonds across the family.

Replacement Considerations

Direct substitutes include other manufacturers' 1N3005 equivalents meeting DO-213AA specifications. Cross-reference with JAN1N3005RB for military qualification if required. Ensure any replacement maintains the 10 W power rating and 100 V Zener voltage to preserve circuit functionality.
