TO-92 Mini
Semiconductor Group 1 1997-09-30
Silicon Spreading Resistance Temperature Sensor in
Miniature Leaded Plastic Package KT 110, KT 210,
KTY 11, KTY 21
Features
• Temperature dependent Resistor with Positive
Temperature Coefficient
• Miniature 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 (KTY-series)
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.
