1

1 Features

1

•

AEC-Q100 qualified for automotive applications:

–

•

Silicon-based thermistor with a

Positive Temperature Coefficient (PTC)

•

Linear resistance change with temperature

–

Simplifies resistance-to-temperature

conversion

–

Decrease accuracy spread compared to non-

linear Negative Temperature Coefficient (NTC)

thermistor-based circuits across a wide

temperature range

•

10-k

Ω nominal resistance at 25°C (R25)

–

±1% maximum (0°C to 70°C)

•

Consistent sensitivity across temperature

–

6400 ppm/°C TCR (25°C)

–

0.2% typical TCR tolerance across

temperature (–40°C to 125°C)

•

Fast thermal response time:

3 Description

The

TMP61-Q1

series

of

small

silicon

linear

thermistors

are

designed

for

temperature

measurement, protection, compensation, and control

systems. Compared to traditional NTC thermistors,

the TMP61-Q1 device offers enhanced linearity and

consistent sensitivity across the full temperature

range. The TMP61-Q1 offers robust performance due

to device immunity to environmental variation and

built-in fail-safe behaviors at high temperatures. This

device is currently available in a 2-pin, surface-mount,

0402 footprint-compatible X1SON package.
