1N5222B-G

Single Zener Diodes Overview

The Comchip Technology 1N5222B-G is a silicon unidirectional voltage regulator diode housed in a DO-35 glass axial leaded package. It provides a nominal Zener voltage of 2.5 V at a test current of 20 mA with a maximum dynamic impedance of 30 Ω and a maximum reverse leakage current of 100 µA. The device supports a maximum power dissipation of 500 mW, operates within a junction temperature range up to 175 °C, and features a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm compliance with RoHS standards and exact electrical tolerances. Ensure the ordering suffix matches the required packaging configuration, as standard bulk or tape-and-reel options may vary by distributor. Cross-reference datasheet revision dates to validate thermal resistance and power derating curves prior to final procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring a stable 2.5 V reference point in through-hole designs. Consider the 500 mW power dissipation limit and the negative temperature coefficient inherent to low-voltage Zener diodes when designing bias networks. Verify that the operating ambient temperature remains within the specified -65 °C to +175 °C junction range to maintain performance reliability.

Single Zener Diodes Part Context

This component belongs to the 1N5221B-G through 1N5267B-G series of axial leaded glass Zener diodes manufactured by Comchip Technology. The series covers a wide voltage range from 2.4 V to 75 V, all sharing the same DO-35 mechanical footprint and 500 mW power rating profile. This specific model represents the lower end of the voltage spectrum within this standardized product family.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5222B variants, such as those produced by Microchip Technology or Central Semiconductor Corp, provided they meet the identical 2.5 V nominal voltage, 500 mW power rating, and DO-35 package constraints.
