1N5242BDO35

Single Zener Diodes Overview

The Microsemi Corporation 1N5242BDO35 is a single Zener diode housed in a DO-35 (DO-204AH) glass axial-lead package. It provides a nominal Zener voltage of 12 V with a standard tolerance of ±5%. The device operates at a test current of 20 mA and dissipates up to 500 mW. Maximum reverse leakage current is specified as 1 µA at 47 V, while the maximum Zener impedance is 30 Ω.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction
• Voltage regulation across broad operating ranges
• Minimal capacitance characteristics
• ESD non-sensitive design

Single Zener Diodes Applications

• Voltage reference circuits
• Voltage regulator applications
• Protection against overvoltage conditions

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications. Confirm RoHS compliance status if environmental restrictions apply. Ensure the manufacturer designation aligns with procurement requirements. Validate the package type for mounting compatibility. Check for any specific military screening prefixes if applicable.

Single Zener Diodes Selection Notes

Select this component when a 12 V reference with ±5% tolerance is required. Consider the 500 mW power dissipation limit for thermal management. Evaluate the low capacitance feature for high-frequency signal integrity. Verify lead length requirements for soldering processes.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers voltages from 2.4 V to 200 V in standard tolerances. These devices are JEDEC registered and available in various screening levels.

Single Zener Diodes Replacement Considerations

Equivalent parts within the 1N5221–1N5281B series may be considered if voltage and tolerance match. Surface mount equivalents exist in the MLL5221 to MLL5281B MELF package family.
