Product details
Overview
KTY83/110,113 from NXP Semiconductors is a silicon-based positive temperature coefficient (PTC) temperature sensor in hermetically sealed SOD68 (DO-34) axial-leaded glass package, delivering 990–1010 Ω resistance at 25 °C, ±1.31 K max temperature error at 25 °C, and 0.76 %/K nominal temperature coefficient - used for precision thermal monitoring in motor windings, power supply thermal protection, and HVAC control circuits.
For engineers reviewing the KTY83/110,113 datasheet, KTY83/110,113 pinout, KTY83/110,113 application, or KTY83/110,113 equivalent, key selection criteria include R25 tolerance, long-term drift under 175 °C stress, thermal time constant in liquid (<1 s), fail-safe PTC behavior, and compatibility with simple voltage-divider readout circuits.
Technical Context
The KTY83/110,113 operates as a two-terminal passive resistive sensor requiring external bias current (recommended 1 mA); its resistance increases monotonically and near-linearly with temperature across −55 °C to +175 °C ambient range. It exhibits fail-safe behavior - resistance rises with overtemperature, enabling direct detection without active circuitry.
Its thermal time constant is 1 s in still liquid and 0.5 s in flowing liquid, supporting rapid thermal response in immersion-sensing applications. Long-term stability is validated at ≤1 Ω resistance drift after 10,000 h at 175 °C ambient, confirming suitability for high-reliability industrial thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| R25 | 990–1010 Ω at 25 °C with 1 mA bias - defines baseline scaling for voltage-divider temperature measurement circuits. |
| Temperature Coefficient | 0.76 %/K typical - enables predictable, monotonic resistance increase per degree, simplifying linearization in analog front-ends. |
| R100/R25 Ratio | 1.65–1.69 - confirms stable PTC behavior at 100 °C, critical for overtemperature trip point calibration. |
| Max Temp Error | ±1.31 K at 25 °C - quantifies absolute accuracy for closed-loop thermal regulation within tight tolerances. |
| Thermal Time Constant | 1 s in still liquid - determines minimum sampling interval for dynamic thermal event capture in fluid-cooled systems. |
| Continuous Current Limit | 10 mA at 25 °C ambient - sets maximum bias current to avoid self-heating errors during measurement. |
| Operating Range | −55 °C to +175 °C - supports deployment in automotive engine bays, industrial motor housings, and power converter heatsinks. |

FAQ
What is the recommended bias current for accurate operation of the KTY83/110,113?
The KTY83/110,113 is specified for 1 mA continuous sensor current (Isen(cont)) to minimize self-heating error and ensure compliance with R25, TC, and temperature error specifications. At 25 °C ambient, up to 10 mA is permitted, but higher currents increase measurement uncertainty due to Joule heating - always verify thermal error budget in final layout. The KTY83/110,113 datasheet explicitly recommends 1 mA for temperatures above 100 °C.
Does the KTY83/110,113 require polarity-aware circuit design?
Yes - the KTY83/110,113 has defined anode (Pin 2) and cathode (Pin 1) terminals, and must be biased in forward direction to operate within its specified R-T characteristics. Reversing polarity may cause non-monotonic behavior or measurement drift. The KTY83/110,113 pinout requires Pin 1 (k) connected to ground or low-side reference and Pin 2 (a) connected to bias voltage through a current-limiting resistor.
How does the KTY83/110,113 compare to thermistors in terms of linearity and calibration effort?
The KTY83/110,113 delivers virtually linear resistance vs. temperature behavior with ±1.31 K max error at 25 °C and <±7.19 K at 175 °C, significantly outperforming NTC thermistors that require 3rd-order polynomial or lookup-table compensation. Its PTC nature and stable TC of 0.76 %/K reduce firmware complexity in microcontroller-based thermal monitoring systems using the KTY83/110,113.
Can the KTY83/110,113 be used in flowing liquid environments such as engine coolant or refrigerant loops?
Yes - the KTY83/110,113 is qualified for immersion in liquids with a thermal time constant of 0.5 s in flowing liquid, enabling rapid response to transient thermal events. Its hermetically sealed SOD68 (DO-34) glass package provides corrosion resistance and long-term reliability in chemically aggressive coolants. Mounting must ensure direct thermal contact, and the KTY83/110,113 must be operated within its −55 °C to +175 °C ambient range.
What is the long-term resistance stability of the KTY83/110,113 under continuous high-temperature stress?
The KTY83/110,113 demonstrates ≤1 Ω resistance drift after 10,000 hours of continuous operation at 175 °C ambient temperature - confirming exceptional long-term stability for mission-critical thermal monitoring. This drift specification directly supports calibration retention in industrial motor drives and power converters where field recalibration is impractical. The KTY83/110,113 data sheet validates this performance under IEC 60134 Absolute Maximum Rating conditions.
