Microchip Digital Output Temperature Sensor Through Hole Mount SMBus Serial-I2C ±3°C 5-Pin TO-220 TC74

Microchip TC74 digital output temperature sensor, model TC74, is engineered for reliable and accurate temperature measurement in industrial, laboratory, and embedded electronics applications. Its through-hole TO-220 package contains a 5-pin configuration allowing SMBus and Serial-I2C communications, providing an 8-bit digital temperature output.

The device operates at a minimal supply voltage range of 2.7V to 5.5V and supports wide ambient operating temperatures from -40°C to 125°C. Accuracy is tightly controlled at ±3°C over the full range, with enhanced ±2°C accuracy between 25°C and 85°C. This precision enables dependable thermal monitoring in HVAC, manufacturing controls, and environmental sensing equipment.

The TC74 sensor features solid-state temperature detection at 1°C resolution, converting sensor readings into digital data accessible via a simple 2-wire SMBus/I2C interface. Its low power consumption - 200 μA during normal operation and only 5 μA in standby mode - makes it suitable for battery-powered and energy-sensitive devices. The configuration register's SHDN bit allows efficient switching to standby, optimizing power management.

The sensor's small compact size (15.57mm height, 10.54mm length, and 4.7mm width) and standard TO-220 through-hole mounting package facilitate easy installation in various circuit boards and thermal management systems. The digital interface supports multi-drop and multi-zone temperature monitoring, useful for complex control and industrial automation systems.

The sensor outputs are delivered as 8-bit digital words for straightforward system integration. Low power consumption enhances suitability in portable and embedded devices. Wide supply voltage range supports diverse electrical environments.

Robust operating temperature range ensures reliability in harsh conditions. Small form factor eases PCB space constraints. SMBus/I2C interface simplifies communication protocols. The TO-220 package allows secure through-hole mounting.

Standby mode reduces power usage when sensing is not required.

This Microchip TC74 Temperature Sensor is widely applicable in industrial measurement, laboratory instrumentation, HVAC systems, manufacturing process monitoring, and other electronics requiring precise temperature feedback. Its reliable accuracy combined with a minimal power footprint makes it an ideal component for modern sensor applications.
