1N5226BE3

Single Zener Diodes Overview

The Microchip Technology 1N5226BE3 is a 0.5 W glass axial-lead Zener diode in the DO-35 package. It provides a nominal Zener voltage of 3.3 V with a ±5% tolerance (B suffix). The device operates within a temperature range of -65°C to +175°C and features a maximum reverse current of 25 µA at 1.9 V, a Zener impedance of 28 Ω at 25 mA, and a negative temperature coefficient of -0.070 %/°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass axial-lead construction for reliable operation
• Inherently radiation hard per MicroNote 050
• Non-sensitive to electrostatic discharge (ESD)
• Minimal capacitance characteristics

Single Zener Diodes Applications

• Voltage regulation over broad operating currents and temperatures
• Reference voltage generation in electronic circuits
• Protection against voltage transients

Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'e3' confirms RoHS compliance and matte-tin plating as specified in the datasheet. Ensure the B suffix is present to guarantee the required 5% voltage tolerance. Confirm the manufacturer origin is Microsemi or its successor entity to ensure adherence to the documented JEDEC registration and screening standards.

Single Zener Diodes Selection Notes

Select this component when a stable 3.3 V reference is required in through-hole designs. The DO-35 package supports flexible axial-lead mounting. Consider the negative temperature coefficient for thermal stability requirements. Verify that the 0.5 W power dissipation rating meets the circuit's steady-state power needs without exceeding derating curves.

Single Zener Diodes Part Context

This part belongs to the 1N5221 through 1N5281B series of 0.5 W Zener Voltage Regulators. The series offers a wide selection from 2.4 to 200 volts. The 'e3' suffix indicates RoHS compliance, while the 'B' suffix specifies the standard 5% voltage tolerance.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available as MLL5221 to MLL5281B in the DO-213AA MELF style package. DO-7 glass body axial-leaded Zener equivalents are also offered by the manufacturer.
