CDLL5985 [Microchip]

Surface mount equivalents to JEDEC registered 1N5985 to 1N6031 series. Similar to operating current conditions of the BZX55 Pro Electron series of Zener products in Europe. Multiple voltage tolerances are available (see part nomenclature). Internal metallurgical bonds. High-reliability screened equivalents in reference to MIL-PRF-19500 are available. RoHS compliant versions available (commercial grade only). Regulates voltage over a broad operating current and temperature range. Extensive selection from 2.4 to 200 volts. Non-sensitive to ESD (MIL-STD-750, method 1020). Minimal capacitance (see Figure 2). Inherently radiation hard as described in Microchip "MicroNote 050".

The popular 1N5985BUR-1 thru 1N6031BUR-1 series of 0.5 watt Zener voltage regulators provides a selection from 2.4 to 200 volts in 10%, 5%, 2% and 1% tolerances.

These glass surface mount DO-213AA Zeners are also available in various military equivalent screening levels by adding a prefix identifier as described in the “part nomenclature” section.

Microchip also offers numerous other Zener products to meet higher and lower power applications.
