SSCMNNN030PASA3

Pressure Sensors Transducers Overview

The Honeywell SSCMNNN030PASA3 is a TruStability series digital pressure sensor designed for board mounting applications. It measures absolute pressure with a working range of 30 PSI (206.84 kPa) and a maximum pressure rating of 60 PSI (413.69 kPa). The device features a piezoresistive silicon sensing element housed in an 8-SMD, J-lead package with no ports. It operates on a supply voltage of 3V to 3.6V and provides a 12-bit digital output via the SPI interface. Accuracy is specified at ±0.25%, and it includes integrated signal amplification and temperature compensation. The unit functions within a temperature range of -40°C to 85°C.

Pressure Sensors Transducers Feature Summary

• Integrated digital SPI interface providing 12-bit resolution data output
• Internal vacuum reference for accurate absolute pressure measurement
• On-chip signal conditioning including amplification and temperature compensation

Pressure Sensors Transducers Applications

• Industrial automation systems requiring precise pressure monitoring
• HVAC equipment control and diagnostics
• Medical devices utilizing low-pressure gas or liquid measurements
• Automotive engine management and emission control systems

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix code to confirm the communication protocol and package variant, as the base part number may correspond to multiple configurations. Ensure that the target application environment remains within the specified operating temperature range of -40°C to 85°C. Confirm that the system power supply stays within the 3V to 3.6V limit to prevent damage. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Pressure Sensors Transducers Selection Notes

Select this component when an absolute pressure reading is required rather than gauge or differential measurements. The SPI interface is suitable for microcontrollers supporting serial communication protocols. Consider the 8-SMD J-lead package for surface mount assembly processes. The ±0.25% accuracy meets requirements for general industrial sensing where high precision is needed without excessive cost. Evaluate the 30 PSI range against expected operational pressures to ensure adequate headroom.

Pressure Sensors Transducers Part Context

This sensor belongs to the TruStability SSC series from Honeywell Sensing and Productivity Solutions. The series focuses on miniaturized, digitally enabled pressure sensing solutions. These sensors integrate silicon piezoresistive technology with ASICs to deliver calibrated and compensated outputs. The family is designed for reliability in demanding environments, offering consistent performance across wide temperature ranges.

Pressure Sensors Transducers Replacement Considerations

Direct replacements must match the absolute pressure type, SPI interface, and 8-SMD J-lead package. Verify that substitute components support the same 3V to 3.6V supply voltage and 12-bit resolution. Cross-reference pinout compatibility to ensure seamless PCB integration without redesign.
