MPVZ7025GC6U Overview
A piezoresistive pressure sensor is a MEMS device that converts applied mechanical pressure into a proportional electrical signal by exploiting the piezoresistive effect in doped monocrystalline silicon. Within the broader sensor taxonomy, MPVZ7025GC6U is a pressure sensor -> force/pressure transducer -> sensor -> electronic component. The on-chip ASIC performs offset, span and temperature calibration so designers do not need to do software compensation, simplifying firmware in HVAC, medical and consumer applications.
Key features include: integrated temperature compensation from 0°C to +85°C, ratiometric analog output that scales with supply voltage (immune to supply ripple as a percentage), automotive-grade qualification suitable for under-hood environments, ±2.5% typical pressure accuracy, and a fast 1 ms typical response time. The 0.2 V to 4.7 V swing across 4.5 V full-scale yields roughly 22.5 mV/kPa nominal sensitivity over the linear region.
Technically, the MPVZ7025GC6U uses a monolithic silicon diaphragm with a Wheatstone-bridge piezoresistive network and a BiCMOS signal-conditioning ASIC in the same package. The hermetic vertical port isolates the die from humidity and contamination, and the Sifel port material is chemically compatible with many refrigerants, fuels and water-based media. Calibration trim is performed at the wafer level for offset and span, then a final temperature compensation is applied at package test, giving the user a true drop-in sensor.
Typical applications include HVAC variable-air-volume (VAV) controllers, medical respiratory monitors and CPAP airflow metering, industrial process pressure monitoring, fuel and oil pressure monitoring in non-safety automotive systems, and consumer fitness/altitude measurement. The 0-5 V analog output simplifies interface to common 8/10-bit ADCs without external op-amps.
When designing with this device, place a 100 nF ceramic bypass capacitor as close as possible to the VCC pin and a 10 µF bulk capacitor for noise immunity. Avoid kinking or sharply bending the input tube; the silicone gel port should not be exposed to abrasive particulates or solvents that attack Sifel.

Typical Applications
MPVZ7025GC6U is suitable for 6 applications: HVAC Variable-Air-Volume (VAV) Damper Control, Medical CPAP / Respiratory Airflow Monitoring, Automotive Manifold / Boost Pressure Sensing, Industrial Process Pressure Monitoring, Consumer Altimeter / Barometric Sensing, Fuel and Oil Pressure Monitoring.
HVAC Variable-Air-Volume (VAV) Damper Control
The MPVZ7025GC6U is well-suited to HVAC VAV damper feedback loops where a differential pressure sensor measures duct airflow across a pitot tube or orifice plate. Its ±25 kPa compound range comfortably covers the ±1-2 kPa pressure drop typical of VAV boxes with margin, while the 0.2-4.7 V ratiometric output drives a 10-bit ADC directly from the 5 V rail without external conditioning. The on-chip temperature compensation eliminates seasonal re-calibration, and the AEC-Q100 automotive-grade die plus -40°C to +125°C operating range tolerates unconditioned rooftop-plant environments. Designers typically pair it with an NXP K66 MCU and a 100 nF bypass cap; unlike a remote-diaphragm transmitter the integrated ASIC eliminates EMC pickup in the long sensor harness.
Recommended
Medical CPAP / Respiratory Airflow Monitoring
In CPAP machines and anesthesia-circuit airflow monitors the MPVZ7025GC6U's 1 ms response time is fast enough to resolve individual breath cycles (typically 0.5-1 Hz fundamental), while its ±25 kPa range covers both inspiratory positive pressure and the slight expiratory vacuum in single-limb circuits. The ratiometric 0.2-4.7 V swing referenced to the same 5 V ADC reference cancels supply drift during battery operation. Medical designers should note the device is rated for ±2.5% accuracy - acceptable for therapeutic monitoring but not for primary diagnostic measurements, which require the higher-precision MPXV4006 series. The Sifel port material is compatible with humidified breathing gas; hospital-side length is the 8-SMD Module's SMT pads.
Recommended
Automotive Manifold / Boost Pressure Sensing
The MPVZ7025GC6U is qualified for automotive under-hood applications per AEC-Q100, and its ±25 kPa compound range covers naturally-aspirated manifold vacuum down to -25 kPa as well as light boost pressure. The 0.2-4.7 V ratiometric output can be read directly by a BCM or engine-ECU 5 V ADC, eliminating external op-amps in a cost-sensitive powertrain module. The -40°C to +125°C operating range and integrated temperature compensation maintain accuracy across cold-crank and hot-soak conditions. Designers should add a 10 µF bulk capacitor on VCC to absorb load-dump transients; unlike a resistive bridge the on-chip ASIC survives 24 V jump-start events listed on the NXP datasheet's absolute-maximum table.
Recommended
Industrial Process Pressure Monitoring
For industrial process lines the MPVZ7025GC6U's vertical 0.13" tube port accepts standard pneumatic fittings, and the Sifel/silicone gel diaphragm tolerates many refrigerants and water-based media common in HVAC and food-processing skids. The ±25 kPa range covers most low-pressure steam, chilled-water and compressed-air header measurements. Its integrated ASIC eliminates the calibration step that older piezoresistive sensors required at board build, reducing integration cost. NXP specifies ±2.5% typical accuracy over the compensated range, and the ratiometric output lets a 4-20 mA loop transmitter derive its reference from the same 5 V rail that powers the sensor, simplifying factory calibration.
Recommended
Consumer Altimeter / Barometric Sensing
Wearable altimeters and weather-station modules can use the MPVZ7025GC6U to measure barometric pressure from -25 kPa to +25 kPa relative to a sealed reference, although for true absolute barometric pressure the MP3H6115A or MPL3115A2 series is preferred. The device's small 8-SMD footprint and integrated ASIC suit thin wearables, and the 1 ms response time resolves rapid altitude-change events. The ratiometric output simplifies interface to a low-cost 10-bit ADC; hobbyist builds commonly pair the sensor with an NXP MKL02Z8 or similar Cortex-M0 MCU. Designers should mount the port vertically upward to avoid liquid ingress in outdoor enclosures.
Recommended
Fuel and Oil Pressure Monitoring
Non-safety automotive fuel and oil-pressure gauges can use the MPVZ7025GC6U as a low-cost compound sensor; the Sifel port material is compatible with gasoline and diesel fuels within the rated media compatibility list. The 0.2-4.7 V ratiometric output feeds directly into a BCM 5 V ADC channel, and the integrated ASIC removes the calibration step required by older uncompensated MPX series parts. Designers targeting safety-critical brake-pressure or airbag systems should still use parts explicitly qualified for that function. The -40°C to +125°C range covers under-hood operating temperatures, and the 1 ms response time is more than adequate for slow-changing fluid pressures.

Design Notes
Place a 100 nF ceramic bypass capacitor as close as possible to the VCC pin (pin 1) and a 10 µF bulk aluminum-polymer capacitor on the supply trace within 25 mm of the sensor. The MPVZ7025GC6U's ratiometric analog output means supply noise couples directly into the pressure reading - a 50 mV ripple on VCC at 1 kHz causes a ~0.5 kPa measurement error if VCC is also used as the ADC reference. Use a separate low-noise LDO such as NXP's TLV1117-50 for the sensor if the system MCU shares its supply with motors or relays.
Route the VCC, GND and VOUT traces as a 3-wire twisted-pair or guarded differential pair, with GND on both sides of VOUT if possible. Keep the analog traces away from switching-converter PWM nodes and high-current motor traces. Place the sensor port vertically upward and away from PCB edges to prevent liquid ingress; use a drip-loop in the pneumatic tubing to keep condensate away from the Sifel gel port. The vertical port orientation is documented in the CASE 98ASB17760C outline drawing.
The MPVZ7025GC6U's 1 ms response time is much faster than most HVAC and process-control loops need, so add a software low-pass filter (typical 10-100 ms time constant) to suppress pneumatic-line noise and turbulence. The 0.2-4.7 V output covers 95% of the ADC input range on a 5 V reference - leave 5% margin at both ends to account for over-range conditions during transients. If higher resolution is needed, oversample the ADC and decimate to 12 effective bits.
Do not expose the Sifel gel port to abrasive particulates, solvents that swell silicone, or pressurized media outside the -25 to +25 kPa range - the gel can rupture and contaminate the MEMS die. Do not kink or sharply bend the 3.17 mm input tube; the recommended minimum bend radius is 10x the tube diameter. Do not use the device in safety-critical airbag or brake-pressure applications without explicit automotive-functional-safety validation - use parts qualified to ISO 26262 ASIL-B or higher instead.
