Product Summary
The 1N4623UR is a 0.5 watt glass surface mount DO-213AA Zener voltage regulator. The 1N4623UR provides a selection from 1.8 to 100 volts in standard 5% tolerances as well as tighter tolerances identified by different suffix letters on the part number. The 1N4623UR is 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. Applications are (1)Regulates voltage over a broad operating current and temperature range; (2)Extensive selection from 1.8 to 100 V; (3)Standard voltage tolerances are plus/minus 5% with no suffix; (4)Tight tolerances available in plus or minus 2% or 1% with C or D suffix respectively; (5)Hermetically sealed surface mount package; (6)Nonsensitive to ESD per MIL-STD-750 Method 1020; (7)Minimal capacitance; (8)Inherently radiati.
Parametrics
1N4623UR absolute maximum ratings: (1)Operating and storage temperature: -65ºC to +175ºC; (2)Thermal resistance: 150℃/W junction to end cap and 300ºC/W junction to ambient when mounted on FR4 PC board (1 oz Cu)with recommended footprint; (3)Steady-state power: 0.5 watts at end cap temperature TEC < 100℃ or ambient temperature TA < 25℃ when mounted on FR4 PC board as described for thermal resistance above; (4)Forward voltage @200 mA: 1.1 volts; (5)Solder temperatures: 260 ℃ for 10 s (max).
Features
1N4623UR features: (1)Surface mount equivalent to JEDEC registered 1N4099 thru 1N4135 and 1N4614 thru 1N4627 series; (2)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); (3)DO-7 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.
