Mechanical Dimensions (mm) Pin Out Pad Function 1 Cathode 2 Anode 3 Anode 4 Cathode 5 [2] Thermal 1 2 5 4 3 Figure 3: Package outline drawing. Notes for Figure 3: 1. Unless otherwise noted, the tolerance = ± 0.20 mm. 2. Thermal contact, Pad 5, is electrically connected to the Anode, Pads 2 and 3. Do not electrically connect any electrical pads to the thermal contact, Pad 5. LedEngin recommends mounting the LZ1-00NW05 to a MCPCB that provides insulation between all electrical pads and the thermal contact, Pad 5. LedEngin offers LZ1-10NW05 and LZ1-30NW05 MCPCB options which provide both electrical and thermal contact insulation with low thermal resistance. Please refer to Application Note MCPCB Options 1 and 3, or contact a LedEngin sales representative for more information.
