The OTP-628D2 is a thermopile sensor in classic TO-46 housing.
The sensor is composed of 116 elements of thermocouple in series on a floating micro-membrane having an active area of diameter 545 μm.
The thermopile sensor provides nearly Johnson-noise-limited performance, which can becalculated by its ohmic series resistance.
A thermistor with a lead connected to ground is alsoprovided inside the TO package for ambient temperature reference.
