1N5241A

Single Zener Diodes Overview

The Microchip Technology 1N5241A is a 0.5 W glass axial-lead Zener diode in the DO-35 package. It provides an 11 V nominal Zener voltage with a standard ±10% tolerance (suffix A). The device operates within a temperature range of -65°C to +175°C and features minimal capacitance. Electrical characteristics include a maximum reverse current of 22 µA at 9.5 V, a Zener impedance of 9.5 Ω at 13 mA, and a positive temperature coefficient of +0.076 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for environmental stability
• Capable of regulating voltage across a broad operating current and temperature range
• Inherently radiation hard per MicroNote 050
• Non-sensitive to electrostatic discharge

Single Zener Diodes Applications

• Voltage regulation circuits requiring stable reference voltages
• Overvoltage protection applications
• Clamping circuits in electronic systems

Single Zener Diodes Procurement Notes

Verify the specific suffix letter on the component marking to confirm the exact voltage tolerance class. Ensure that the procurement documentation matches the JEDEC registered type number for the intended electrical specifications. Confirm the package style aligns with the required through-hole mounting configuration before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a 0.5 W power dissipation rating in a glass axial-lead package is required. The 11 V breakdown voltage suits applications needing precise low-voltage references. Consider the positive temperature coefficient for thermal compensation requirements in the design environment.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage selection from 2.4 V to 200 V. These devices are JEDEC registered and available in various screening levels and tolerance options.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as MLL5221 to MLL5281B in the DO-213AA MELF style package. Other manufacturers may offer compatible parts under different JEDEC numbering schemes.
