U: Lead-free (Sn 100%), halogen-free
Package abbreviation and IC packing specifications*1
M5T1: SOT-23-5, Tape
I4T1: SNT-4A, Tape
A4T2: HSNT-4 (1010), Tape
Output form and output logic*3
A: CMOS output, active "H"
B: CMOS output, active "L"

D: Nch open-drain output, active "L"
50 to 95, A0
(When detection temperature is +80°C, it is expressed as 80.
When detection temperature is +100°C, it is expressed as A0.)
*1. Refer to the tape drawing.
*2. The hysteresis temperature is selectable in 5°C, 10°C, 15°C, or 20°C.
However, if the detection temperature is +50°C, select the hysteresis temperature in 5°C or 10°C.
*3. For the DET pin output, selectable the output logic active "H" or active "L".
For the DET pin output, selectable the output form CMOS or Nch open-drain.
*4. Detection temperature (TDET) is settable in +50°C to +100°C, in +5°C step.
