The TO-46 header is one of the smallest TO-style headers for thermoelectric cooler (TEC) integrating. Thermoelectric coolers (TECs) on TO-46 are mainly used for VCSEL cooling and similar low-power semiconductor laser diodes, as well as in some types of optical sensors. Despite the very small space for TEC mounting (~1.2x2.3mm2), the number of thermoelectric coolers compatible with TO-46 in TEC Microsystems' standard product line is over three dozen.
TEC Microsystems uses TO-46 with 5 and 6pins, which is usually enough to for TEC, temperature sensor and LD chip. TO-46 headers have Au plating suitable for wire bonding (WB).
Two orientations of the TEC relative to the header pins are available. The thermoelectric cooler itself can be mounted on TO-46 header with WB pads for further bonding or connected to the header pins (by wire or solder drop). TEC is mounted on TO-46 by soldering (Sn-Ag-In, Tmelt=206ºC), thanks to this TO-46 based sub-assembly can withstand short term heat up to 200ºC in subsequent assembly steps.
The most common and typical TEC solutions with TO-46 based packages are shown in the table below. The total number of available configurations is much higher.
