| ZNI1000 TEMPERATURE SENSOR DESCRIPTION The ZNI1000 is a Ni thin film Resistance Temperature Detector (RTD), specified to DIN 43760. The high temperature coefficient offers higher signal outputs than other RTD's, which results in higher accuracy with smaller temperature changes. FEATURES * Resistance at 0 C: 1000 * SOT23 package * Available on 8mm tape SOT23 APPLICATIONS * Automotive electronic * Circuit protection * Temperature compensation * Temperature measurement PINOUT ORDERING INFORMATION DEVICE ZNI1000TA ZNI1000TC REEL SIZE 7" 13" TAPE WIDTH 8mm 8mm QUANTITY PER REEL 3,000 units 10,000 units Top View DEVICE MARKING * ZNI Pin 1 - Ni1000 Pin 2 - Ni1000 Pin 3 - need a good thermal contact for a short response time Issue 4 - April 2006 1 SEMICONDUCTORS ZNI1000 ABSOLUTE MAXIMUM RATINGS PARAMETER Continuous current Total power dissipation Operating temperature range Storage temperature range SYMBOL I CC P TOT T amb T stg LIMIT 4 20 -55 to +150 -55 to +150 UNIT mA mW C C ELECTRICAL CHARACTERISTICS PARAMETER Resistance 0C Resistance 100C Tolerance class B Tolerance class B SYMBOL R0 R 100 MIN TYP 1000 1618 (0.4+0.028 x T ) (0.4+0.007 x T ) MAX UNIT CONDITIONS T=0 C, I<1mA T=100 C, I<1mA -55 to 0C 0 to 150C CHARACTERISTICS ACCORDING TO DIN43760 Resistance at a given temperature R0 Resistance at 0 C B 6.650 x 10-6 T Temperature in C C 2.805 x 10-11 A 5.485*10-3 D -2.000 x 10-17 R(T) = R0 x (1 + A x T + B x T2 + C x T4 + D x T6) Issue 4 - April 2006 SEMICONDUCTORS 2 ZNI1000 Formula for temperature at a given resistance: T (R ) = a + bR + cR 2 + dR 3 coefficients: a.= -232.2 b.= 0.290 c.= -66.65 x 10-6 d.= -8.85 * 10-9 Tolerances: Class B +/- (0,4 + 0,007 *|T|) in range from 0 to 150C +/- (0,4 + 0,028 *|T|) in range from -55 to 0C R0 = 1000 Ohm at 0C operating -55 to +150C storage -55 to +150C R = 0,1 % after 1000 h at 150C typ. 1,2 mA; max. 5 mA Specification: Temperature range: Long Term stability: Measurement Current (DC): Self heating For accurate temperature measurement it's recommended to choose a small current in order to avoid self heating of the resistor. The temperature failure caused by the measurement current can be calculated with: T = P/EK where P = I * R is the heat power caused by the measurement current and EK is the self heating coefficient. The self heating coefficient for the Ni1000-SOT is EW=(1,7 0,3) mW/K (Air: 23C; no air flow) Issue 4 - April 2006 3 SEMICONDUCTORS ZNI1000 Issue 4 - April 2006 SEMICONDUCTORS 4 ZNI1000 PACKAGE OUTLINE PAD LAYOUT CONTROLLING DIMENSIONS IN MILLIMETERS APPROX CONVERSIONS INCHES PACKAGE DIMENSIONS Millimeters DIM A B C D F G 0.37 0.085 Min 2.67 1.20 Max 3.05 1.40 1.10 0.53 0.15 0.015 0.0034 Inches Min 0.105 0.047 Max 0.120 0.055 0.043 0.021 0.0059 DIM H K L M N Millimeters Min 0.33 0.01 2.10 0.45 Max 0.51 0.10 2.50 0.64 Inches Max 0.013 0.0004 0.083 0.018 Max 0.020 0.004 0.0985 0.025 0.95 NOM 0.0375 NOM 1.90 NOM 0.075 NOM (c) Zetex Semiconductors plc 2005 Europe Zetex GmbH Streitfeldstrae 19 D-81673 Munchen Germany Telefon: (49) 89 45 49 49 0 Fax: (49) 89 45 49 49 49 europe.sales@zetex.com Americas Zetex Inc 700 Veterans Memorial Hwy Hauppauge, NY 11788 USA Telephone: (1) 631 360 2222 Fax: (1) 631 360 8222 usa.sales@zetex.com Asia Pacific Zetex (Asia) Ltd 3701-04 Metroplaza Tower 1 Hing Fong Road, Kwai Fong Hong Kong Telephone: (852) 26100 611 Fax: (852) 24250 494 asia.sales@zetex.com Corporate Headquarters Zetex Semiconductors plc Zetex Technology Park Chadderton, Oldham, OL9 9LL United Kingdom Telephone (44) 161 622 4444 Fax: (44) 161 622 4446 hq@zetex.com These offices are supported by agents and distributors in major countries world-wide.
