1N4749UR [Microchip]

This surface mountable 1 watt Zener diode series is electrically equivalent to the 1N4728A thru 1N4764A registration in the DO-41 equivalent package except that it meets the JEDEC surface mount outline DO-213AB. It is an ideal selection for applications of high density and low parasitic requirements for voltage regulation. Standard voltage tolerance is +/- 5% with tighter tolerances available down to 1%. With its glass hermetic qualities, it may also be used for high reliability applications when required by a source control drawing (SCD).

Electrically similar to the JEDEC registered 1N4728 thru 1N4764 zener series.

Zener voltages available 3.3V to 100V.

Standard voltage tolerances are +/- 5% with “A” suffix and 10 % with no suffix identification.

Tight tolerances available in plus or minus 2% or 1% with C or D suffix respectively.

Options for screening in accordance with MIL-PRF-19500 for JAN, JANTX, JANTXV, and JANS are available by adding MQ, MX, MV, or MSP prefixes respectively to part numbers.

Surface mount equivalents also available as SMAJ4728A to SMAJ4764A and SMAJ4728A to SMAJ4764A.

RoHS Compliant devices also available by adding e3 suffix.

Plastic body axial-leaded Zener equivalents are also available as 1N4728A to 1N4764A.

Regulates voltage over a broad operating current and temperature range.

Wide selection from 3.3 to 100V.

Leadless package for surface mounting.
