Datasheet SHT20P www.sensirion.com Version 4 – May 2014 7/10 6 Environmental Stability The SHT2x sensor series were tested based on AEC- Q100 Rev. G qualification test method where applicable. Sensor specifications are tested to prevail under the AEC- Q100 temperature grade 1 test conditions listed in Table 912. Sensor performance under other test conditions cannot be guaranteed and is not part of the sensor specifications. Especially, no guarantee can be given for sensor performance in the field or for customer’s specific application. Environment Standard Results13 HTOL 125°C, 408 hours Pass TC -50°C - 125°C, 1000 cycles Pass UHST 130°C / 85%RH / ≈2.3bar, 96h Pass THB 85°C / 85%RH, 1000h Pass HTSL 150°C, 1000h Pass ELFR 125°C, 48h Pass ESD immunity HBM 4kV, MM 200V, CDM 750V/500V (corner/other pins) Pass Latch-up force current of ±100mA with Tamb = 125°C Pass Table 5: Qualification tests: HTOL = High Temperature Operating Lifetime, TC = Temperature Cycles, UHST = Unbiased Highly accelerated Stress Test, THB = Temperature Humidity Biased, HTSL = High Temperature Storage Lifetime, ELFR = Early Life Failure Rate. For details on ESD see Sect. 4.1. If sensors are qualified for reliability and behavior in extreme conditions, please make sure that they experience same conditions as the reference sensor. It should be taken into account that response times in assemblies may be longer, hence enough dwell time for the measurement shall be granted. For detailed information please consult Application Note “Qualification Guide”. 7 Packaging 7.1 Packaging Type SHT2x sensors are provided in DFN packaging (in analogy with QFN packaging). DFN stands for Dual Flat No leads. The sensor chip is mounted to a lead frame made of Cu and plated with Ni/Pd/Au. Chip and lead frame are over molded by green epoxy-based mold compound. Please note that side walls of sensors are diced and hence lead 12 Sensor operation temperature range is -40 to 125°C (AEC-Q100 temperature grade 1). 13 According to accuracy and long term drift specification given on Page 2. frame at diced edge is not covered with respective protective coating. The total weight of the sensor is 25mg. 7.2 Filter Cap and Sockets For SHT2x a filter cap SF2 is available. It is designed for fast response times and compact size. Please find the datasheet on Sensirion’s web page. For testing of SHT2x sensors sockets, such as from Plastronics, part number 10LQ50S13030 are recommended (see e.g. www.locknest.com). 7.3 Traceability Information All SHT20 are laser marked with an alphanumeric, five- digit code on the sensor – see Figure 11. Figure 11 Laser marking on sensor. For details see text. The marking on the sensor consists of two lines with five digits each. The first line denotes the sensor type (SHT20). The first digit of the second line defines the output mode (D = digital, Sensibus and I2C, P = PWM, S = SDM). The second digit defines the manufacturing year (0 = 2010, 1 = 2011, etc.). The last three digits eventually represent an alphanumeric tracking code. That code can be decoded by Sensirion only and allows for tracking on batch level through production, calibration and testing – and will be provided upon justified request. Reels are also labeled, as displayed in Figure 12 and Figure 13, and give additional traceability information. Figure 12: First label on reel: XX = Sensor Type (20 for SHT20), O = Output mode (D = Digital, P = PWM, S = SDM), NN = product revision no., Y = last digit of year, RRR = number of sensors on reel divided by 10 (200 for 2000 units), TTTTT = Traceability Code.
