SOT-23
Semiconductor Group 1 03.97
Silicon Spreading Resistance Temperature Sensor in
Surface Mount Technology KT 130, KT 230,
KTY 13, KTY 23
Features
• Temperature dependent Resistor with Positive
Temperature Coefficient
• SMD plastic package for very small thermal time
constants
• Fast response
• High reliability due to multilayer gold contacts
• n-conducting silicon crystal
• Polarity independent due to symmetrical
construction
• Available selected in ±1% tolerance groups
1) ESD Class 1. When the temperature sensor is operated with long supply leads, it should be protected through
the parallel connection of a > 10 nF capacitor to prevent damage to the sensor through induced voltage peaks.
