Product details
Overview
MPXHZ6115A6T1 from NXP Semiconductors (formerly Freescale) is an absolute pressure sensor IC with monolithic silicon piezoresistive sensing element, on-chip bipolar op amp signal conditioning, and thin-film resistor networks. It delivers 4.7 V typical full-scale output at 5.0 V supply, ±1.5% accuracy over 0 °C to 85 °C, and operates across 15–115 kPa pressure range for engine manifold or barometric measurement.
For engineers reviewing the MPXHZ6115A6T1 datasheet, MPXHZ6115A6T1 pinout, MPXHZ6115A6T1 application, or MPXHZ6115A6T1 equivalent, this page provides verified technical context, pin-level design meaning, real-world use cases in automotive MAP and weather station systems, and validated alternative part options with documented functional differences.
Technical Context
The MPXHZ6115A6T1 integrates a vacuum-referenced silicon diaphragm with fluorosilicone gel isolation, enabling stable absolute pressure sensing in humid or chemically aggressive environments. Its ratiometric analog output scales linearly with supply voltage (4.75–5.25 V), and internal temperature compensation maintains performance from –40 °C to +125 °C.
Signal conditioning includes factory-trimmed offset (0.200 V typ. at min pressure) and full-scale span (4.500 V typ.), yielding 45 mV/kPa sensitivity. The device uses a super small outline package (Case 98ARH99066A) with 8-pin leadframe and chamfered corner pin-1 identification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 15–115 kPa absolute - matches standard atmospheric variation (85–105 kPa) and engine manifold vacuum/boost conditions. |
| Supply Voltage | 4.75–5.25 V DC - ratiometric operation ensures output scaling with MCU reference voltage for simplified ADC calibration. |
| Full-Scale Output | 4.700 V typical at 5.0 V supply - enables direct interface with 5 V ADCs without level-shifting or amplification. |
| Accuracy | ±1.5% of full-scale span (0–85 °C) - includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset errors. |
| Response Time | 1.0 ms (10% to 90%) - supports dynamic pressure monitoring in fast-cycling combustion or HVAC control loops. |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive locations and industrial outdoor enclosures. |
| Package | Super Small Outline Package (SSOP), Case 98ARH99066A - 10.79 × 10.79 × 2.54 mm footprint compatible with automated SMT assembly. |
Pinout & Package
MPXHZ6115A6T1 uses a thermoplastic (PPS) surface-mount super small outline package (Case 98ARH99066A), 8-pin, with chamfered corner denoting Pin 1. The package is media-resistant due to fluorosilicone gel encapsulation of die and wire bonds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | DNC | Do not connect - no internal connection; used only for mechanical orientation via chamfered corner. |
| Pin 2 | VS | Voltage supply input - must be regulated 4.75–5.25 V; powers internal op amp and sensing bridge. |
| Pin 3 | GND | Analog ground reference - requires low-impedance return path to minimize noise coupling into VOUT. |
| Pin 4 | VOUT | Analog output - ratiometric voltage proportional to absolute pressure (0.200 V at 15 kPa, 4.700 V at 115 kPa). |
| Pins 5–8 | DNC | Do not connect - electrically isolated; no internal bond wires or circuitry attached. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Validated from –40 °C to +125 °C - eliminates need for external thermal sensors or software correction tables in embedded systems. |
| Media-resistant construction | Fluorosilicone gel isolation - protects die against humidity, condensation, and common automotive fluids without requiring external housings. |
| High output signal level | 4.5 V full-scale span - reduces susceptibility to noise and simplifies anti-aliasing filter design versus millivolt-output sensors. |
| Monolithic integration | Silicon micromachined diaphragm + bipolar op amp + thin-film resistors - ensures long-term stability and eliminates inter-die drift. |
| Ratiometric transfer function | VOUT = VS × (0.009 × P − 0.095) - enables direct correlation between ADC reading and pressure, independent of supply tolerance. |
Applications
| Engine Manifold Absolute Pressure (MAP) | Weather Station Barometer |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXH6115A6T1 | No media-resistant gel; bare die exposed to environment - lower cost but unsuitable for humid or fluid-exposed installations. | Limited to dry-air or inert gas environments; not rated for automotive under-hood or outdoor weather exposure. | Select MPXH6115A6T1 only when media resistance is unnecessary and BOM cost is prioritized over long-term reliability. |
| MPXA6115A6T1 | Same pressure range and accuracy, but in larger small-outline package (Case 98ASB17756C) - 12.7 × 10.79 mm vs. 10.79 × 10.79 mm. | Requires larger PCB footprint; lacks fluorosilicone gel - less robust in high-humidity industrial settings. | Choose MPXA6115A6T1 if SSOP placement constraints prevent use of MPXHZ6115A6T1, and environmental sealing is handled externally. |
Compared with MPXH6115A6T1 and MPXA6115A6T1, the MPXHZ6115A6T1 uniquely combines super-small SSOP packaging, fluorosilicone media protection, and full automotive temperature qualification - making it the only option among the three suitable for unsealed, high-reliability MAP or barometric deployments.

FAQ
What is the pressure reference type of the MPXHZ6115A6T1?
The MPXHZ6115A6T1 is an absolute pressure sensor with a sealed vacuum reference cavity behind its silicon diaphragm. This means its output corresponds to pressure relative to perfect vacuum - critical for barometric readings and manifold absolute pressure (MAP) measurement where ambient variations matter. The MPXHZ6115A6T1 does not require external venting or atmospheric reference ports.
Does the MPXHZ6115A6T1 require external calibration components?
No, the MPXHZ6115A6T1 includes fully integrated on-chip temperature compensation and factory-trimmed offset and span. Its ratiometric output (VOUT = VS × (0.009 × P − 0.095)) eliminates the need for external resistors, op amps, or calibration EEPROM. Users only need a stable 5 V supply and basic RC filtering (e.g., 100 nF capacitor at VOUT) per the recommended application circuit in the MPXHZ6115A6T1 datasheet.
What is the maximum pressure rating for the MPXHZ6115A6T1?
The MPXHZ6115A6T1 has a maximum pressure rating of 400 kPa, well above its 15–115 kPa operating range. This 3.5× overpressure margin prevents damage during transient spikes, such as backfire events in engine manifolds or rapid valve actuation in industrial vacuum systems. Operation beyond 115 kPa will saturate the output but will not degrade long-term accuracy if within the 400 kPa limit.
Can the MPXHZ6115A6T1 be used in humid or outdoor environments?
Yes - the MPXHZ6115A6T1 features fluorosilicone gel encapsulation that isolates the silicon die and wire bonds from moisture, condensation, and common automotive fluids while transmitting pressure accurately. This makes it suitable for under-hood engine control, outdoor weather stations, and unsealed industrial enclosures where IP-rated housings are impractical. Its qualification across –40 °C to +125 °C further supports outdoor deployment.
What is the supply current consumption of the MPXHZ6115A6T1?
The MPXHZ6115A6T1 draws 6.0 mA typical and up to 10 mA maximum supply current at 5.0 V. This low quiescent current enables use in battery-powered weather stations or portable diagnostic tools without significant impact on runtime. The current remains stable across temperature and pressure - no additional biasing or current-limiting circuitry is required beyond standard decoupling capacitors.
