Poke-home Connector MCPCB
with thermistor for LZP emitter family
LZP-H0xxT1
4x6 configuration
Key Features
Poke-home connectors already mounted on the MCPCB for easy connections
1-channel configuration allows for easy driver control for LZP emitters
Very low Thermal Resistance for MCPCB adds only 0.1C/W
Zener Diodes for ESD protection
On-board thermistor for common constant current source with thermal feedback option
LuxiGen LZP Lens family (15 / 23 / 32) holders align with the MCPCB cutouts
Optional center die control for custom emitters
Description
The LZP-HxxxT1, MCPCB with three 2-pin poke-home connectors provides a convenient method to
connect LED Engins LZP emitters. One 2 pin poke-home connector supports 4 parallel strings of 6 die in
series; a second one is for connecting to the thermistor, and a third one is available for an optional
center die for custom emitters. Four recessed features allow the use of M3 or #4-40 screws to mount
the MCPCB to a heat sink. There are additional mounting holes for the complementary TIR lenses and
Zener diodes for enhanced ESD protection.

Note for Figure 1:
Unless otherwise noted, the tolerance = 0.2 mm. angle = 1
Slots in MCPCB are for M3 or #4-40 mounting screws. Maximum torque should not exceed 1N-m ( 8.9 lbf-in)
LED Engin recommends plastic washers to electrically insulate screws from solder pads and electrical traces.
LED Engin recommends using thermally conductive interface material when attaching the MCPCB to a heatsink
Use solid or stranded wires with gauge size, 18, 20, 22 or 24AWG. See section on Wire Insertion and Extraction for further
instructions.
