1N4131UR [Microchip]

The 1N4099UR-1 through 1N4135UR-1 and 1N4614UR-1 through 1N4627UR-1 series are 500 mW, Zener voltage regulators in the surface mount, glass DO-213AA package. Voltages from 1.8 to 100V in 5%, 2%, and 1% tolerances are available. They are constructed with an internal metallurgical bond and are mil-qualified up to the JANS level for high reliability applications.

Surface mount equivalent to JEDEC registered 1N4099 through 1N4135 and 1N4614 through 1N4627 series.

Internal metallurgical bond.

Max noise density 40 uV / vHz for 6.8 V and up.

Falls quickly to 1 uV / VHz at lower voltages.

JAN, JANTX, JANTXV and JANS qualifications are available per MIL-PRF-19500/435.

This series is also available commercially with the CDLL prefix (CDLL4099-1- CDLL4135-1 and CDLL4614-1 - CDLL4627-1).

This CDLL prefix also replaces the MLL prefix on prior devices.

RoHS compliant versions available (commercial grade only).

Regulates voltage over broad ranges of current and temperature.

Extensive selection from 1.8 to 100 volts.

Voltage tolerances of 5% (standard), 2% and 1% are available.

Hermetically sealed surface mount package.

Non-sensitive to ESD per MIL-STD-750 method 1020.

Minimal capacitance (see Figure 3).

Inherently radiation hard as described in Microchip MicroNote 050.
