Product details
Overview
KTY83/150,113 from NXP Semiconductors is a silicon-based positive temperature coefficient (PTC) temperature sensor in SOD68 (DO-34) axial-leaded glass package, with nominal resistance R25 = 1000 Ω ±5%, temperature coefficient TC = 0.76 %/K, and operating range from −55 °C to +175 °C. It delivers fail-safe behavior and near-linear resistance vs. temperature response for analog temperature monitoring in automotive engine control units, industrial motor windings, and power supply thermal protection circuits.
For engineers reviewing the KTY83/150,113 datasheet, KTY83/150,113 pinout, KTY83/150,113 application, or KTY83/150,113 equivalent, this page provides verified technical context, pin-level circuit roles, real-world use value per application, and two validated alternative parts with documented functional and application differences.
Technical Context
The KTY83/150,113 operates as a two-terminal passive resistive sensor requiring external bias current (typically 1 mA) to generate voltage proportional to temperature. Its PTC behavior ensures monotonic, predictable resistance increase over full −55 °C to +175 °C range, enabling direct analog readout without signal conditioning ICs.
Thermal time constant is 20 s in still air, 1 s in still liquid, and 0.5 s in flowing liquid - confirming suitability for both slow ambient monitoring and rapid fluid-temperature feedback. Maximum continuous sensor current is 10 mA at 25 °C, derating to 2 mA at 175 °C to limit self-heating error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| R25 | 950–1050 Ω at 25 °C; defines baseline resistance for calibration and scaling of analog temperature measurement circuits |
| TC | 0.76 %/K typical; enables accurate linearized temperature calculation over wide range using simple polynomial correction |
| R100/R25 | 1.65–1.69; confirms stable PTC ratio between 100 °C and 25 °C, critical for high-temperature fault detection thresholds |
| Tamb Range | −55 °C to +175 °C; supports under-hood automotive, industrial furnace, and high-reliability power electronics monitoring |
| τth (liquid) | ≤1 s in still liquid; allows responsive thermal feedback in coolant, oil, or transformer fluid sensing applications |
| Isen(cont) | 10 mA max at 25 °C; sets upper limit for excitation current to avoid >1 K self-heating error in precision measurements |
Pinout & Package
Package: SOD68 (DO-34), hermetically sealed glass axial-leaded package with 2 mm diameter body and 25.4 mm minimum lead length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (k) | Connected to lower-potential side of bias network; polarity-sensitive for correct forward-bias operation in series-sensing configurations |
| 2 | Anode (a) | Connected to higher-potential side of bias network; forms current path through silicon junction for resistance measurement |
Key Features
| Feature | Design Value |
|---|---|
| Fail-safe PTC behavior | Resistance increases monotonically with temperature - open-circuit failure mode alerts system before catastrophic overheating |
| Virtually linear R–T curve | ±1.31 K max error at 25 °C and ±6.55 K at 100 °C enables 2nd-order compensation instead of complex lookup tables |
| Long-term stability | ΔR25 ≤ 1 Ω drift after 10,000 h at 175 °C - ensures calibration integrity in mission-critical thermal shutdown systems |
| High-temperature capability | Rated to +175 °C ambient - suitable for direct mounting on IGBT heatsinks, motor stators, and exhaust gas recirculation valves |
Applications
| Automotive Engine Coolant Monitoring | Industrial Motor Winding Protection |
|---|---|
|
Use Scenario: Mounted in coolant reservoir or radiator hose to monitor real-time engine coolant temperature for ECU fan control and overheat shutdown. IC Role / Device Role / Timing Role: Passive resistive sensor providing analog voltage output proportional to coolant temperature via constant-current source. Use Value: R25 tolerance (±5%) and R100/R25 ratio (1.65–1.69) enable accurate 0–120 °C measurement with <±2 K error after 2-point calibration. |
Use Scenario: Embedded in motor winding insulation to detect abnormal heating during overload or phase-loss conditions. IC Role / Device Role / Timing Role: Two-terminal thermal transducer directly interfaced to comparator or ADC input of motor protection relay. Use Value: 175 °C max ambient rating and 1 s thermal time constant in oil allow rapid detection of winding hot spots before insulation breakdown. |
| Power Supply Thermal Foldback | Industrial Oven Temperature Feedback |
|
Use Scenario: Mounted on heatsink of SMPS MOSFETs to trigger current foldback when junction temperature exceeds safe limit. IC Role / Device Role / Timing Role: Analog temperature reference element in discrete op-amp comparator circuit that reduces output current above threshold. Use Value: Fail-safe PTC behavior ensures foldback activates even if bias resistor fails open - preventing thermal runaway. |
Use Scenario: Installed in oven wall or air duct to provide closed-loop temperature feedback to PID controller. IC Role / Device Role / Timing Role: Primary sensing element in analog temperature loop; resistance measured by Wheatstone bridge or ratiometric ADC. Use Value: Long-term stability (≤1 Ω drift at 175 °C/10,000 h) maintains oven setpoint accuracy over years of continuous operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PTC temperature sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| KTY83/120 | R25 = 980–1020 Ω; tighter initial tolerance (±2%) but lower max temp (150 °C) | Better accuracy at 25 °C, but unsuitable for >150 °C environments like exhaust manifolds or high-temp motors | Select when precision at room temperature outweighs extended high-temp coverage |
| TSI301-103 | R25 = 10 kΩ; 10× higher base resistance; same SOD68 package and 0.76 %/K TC | Enables higher signal voltage per mA bias, reducing noise sensitivity in long-wire industrial installations | Select when longer cable runs or noisy environments require improved SNR without changing PCB layout |
Compared with KTY83/150,113, KTY83/120 offers tighter R25 tolerance but sacrifices 25 °C of upper-range capability, while TSI301-103 retains identical thermal specs but scales resistance for better noise immunity - making each choice dependent on whether accuracy, temperature ceiling, or signal robustness dominates the design requirement.

FAQ
What is the maximum continuous operating current for KTY83/150,113 at 25 °C?
The maximum continuous sensor current for KTY83/150,113 is 10 mA at an ambient temperature of 25 °C. This limit ensures self-heating remains below 1 K, preserving measurement accuracy. At elevated temperatures - such as 175 °C - the rated maximum drops to 2 mA to maintain reliability and prevent accelerated aging of the silicon junction.
Does KTY83/150,113 require polarity-aware circuit design?
Yes, KTY83/150,113 has defined anode (pin 2) and cathode (pin 1) terminals and must be biased in forward direction for proper operation. Reversing polarity does not damage the device but causes non-monotonic resistance behavior outside its specified PTC range. Correct orientation ensures predictable, linearized temperature response across −55 °C to +175 °C.
How does the R100/R25 ratio of KTY83/150,113 impact high-temperature fault detection?
The R100/R25 ratio of 1.65–1.69 for KTY83/150,113 provides a stable, repeatable resistance increase at 100 °C relative to 25 °C - enabling reliable threshold detection in overtemperature protection circuits. This ratio's tight specification ensures consistent trip points across production lots, eliminating need for unit-specific calibration in safety-critical applications like motor winding monitoring.
Can KTY83/150,113 be used in flowing liquid environments?
Yes, KTY83/150,113 achieves a thermal time constant of 0.5 s in flowing liquid, making it suitable for real-time temperature monitoring in fuel lines, hydraulic systems, and cooling loops. Its hermetically sealed SOD68 glass package prevents moisture ingress, and the axial lead configuration allows direct insertion into threaded fittings or clamped mounting in pipe manifolds.
What is the resistance drift specification for KTY83/150,113 after long-term operation?
KTY83/150,113 exhibits ≤1 Ω resistance drift at 25 °C after 10,000 hours of continuous operation at 175 °C ambient - confirming exceptional long-term stability. This low drift preserves calibration integrity in applications such as industrial ovens or automotive transmission control units where recalibration is impractical, ensuring consistent performance over multi-year service life.
