1N5245A

Single Zener Diodes Overview

The Microchip Technology 1N5245A is a unidirectional voltage regulator diode with a nominal Zener voltage of 15 V and a power dissipation rating of 0.5 W at 25°C. It utilizes a glass axial-lead DO-35 package. The device features a maximum reverse current of 10 μA at 10 V for the A suffix, a Zener impedance of 16 Ohms at IZK, and a voltage temperature coefficient of +0.082 %/°C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features minimal capacitance characteristics suitable for high-frequency applications
• Constructed with a hermetically sealed glass axial-lead body for durability

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection systems
• Clamping applications in electronic circuits

Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the component was originally produced by Microsemi Scottsdale Division and may now be distributed under Microchip Technology branding. Confirm that the part number corresponds to the standard JEDEC registered type without additional military screening prefixes or RoHS compliance suffixes unless explicitly required for the application environment.

Single Zener Diodes Selection Notes

Select this component when a 15 V regulation point is required within a low-power design constrained by the 0.5 W thermal limit. Ensure the circuit operates within the specified -65°C to +175°C temperature range and accounts for the positive temperature coefficient inherent to this voltage level.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5281B series of 0.5 watt Zener Voltage Regulators. The series offers a wide selection of voltages from 2.4 to 200 volts in standard 5% or 10% tolerances, housed in the common DO-35 glass axial-lead package.

Single Zener Diodes Replacement Considerations

Equivalent parts include other manufacturers' 1N5245A variants meeting the same JEDEC specifications. Surface mount equivalents are available in the MLL5221 to MLL5281B series using the DO-213AA MELF style package.
