1N4099UR thru 1N4135UR (or MLL4099 thru MLL4135) and 1N4614UR thru 1N4627UR (or MLL4614 thru MLL4627) GLASS SURFACE MOUNT 0.5 WATT ZENERS

DESCRIPTION The 1N4099UR thru 1N4135UR and 1N4614UR thru 1N4627UR series of 0.5 watt glass surface mount DO-213AA Zener voltage regulators provides a selection from to 100 volts in standard 5% tolerances as well as tighter tolerances identified by different suffix letters on the part number. These are also available with an internal-metallurgical-bond option by adding a "-1" suffix (see separate data sheet) including JAN, JANTX, and JANTXV military qualifications. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

Surface mount equivalent to JEDEC registered 1N4099 thru 1N4135 and 1N4614 thru 1N4627 series Internal metallurgical bond option available by adding a "-1" suffix that also includes JAN, JANTX, and JANTXV qualifications per MIL-PRF-19500/435 (see separate data sheet for same part numbers with "-1" suffix) or DO-35 glass body axial-leaded Zener equivalents also available per JEDEC registration (see separate data sheet for part numbers 1N4099 thru 1N4135 and 1N4614 thru 1N4627 series
