Open the catalog to page 5TDC-GP211 Overview TDC-GP21 is next generation's upgrade for TDC-GP2. It offers pin-to-pin and functional compatibility, several feature improvements and an extended functionality. Analog elements like a chopper stabilized comparator and analog switches simplify external circuits in a significant manner. In parallel, measurement quality is improved and operating current is reduced. The firepulse generator is extended, a new low-power 32 kHz oscillator driver is implemented and the temperature measuring unit is further improved. All in all, the TDC-GP21 is perfectly suited to design...

Moisture Sensitive Level (MSL) Based on JEDEC 020 Moisture Sensitivity Level definition the TDC -GP21 is classified as MSL 1. Soldering Temperature Profile The temperature profile for infrared reflow furnace (in which the temperature is the resin’s surface temperature) should be maintained within the range described below. Figure 2-9 Soldering profile acam messelectronic gmbh - Friedrich-List-Str.4 - 76297 Stutensee - Germany - www.acam.de
Open the catalog to page 22Maximum temperature The maximum temperature requirement for the resin surface, given 260ºC as the peak temperature of the package body’s surface, is that the resin surface temperature must not exceed 250ºC for more than 10 seconds. This temperature should be kept as low as possible to reduce the load caused by thermal stress on the package , which is why soldering for short periods only is recommended. In addition to using a suitable temperature profile, we also recommend that you check carefully to confirm good soldering results. Date Code: YYWWA: YY = Year, WW = week, A = Assembly site...
