DATA SHEET
HAL 2xy
Unipolar Sensors:
1.4. Operating Junction Temperature Range
The output turns low with the magnetic south pole on
the branded side of the package and turns high if the
magnetic field is removed. The sensor does not
respond to the magnetic north pole on the branded side.
The Hall sensors from Micronas are specified to the
chip temperature (junction temperature TJ).
K: TJ = −40 °C to +140 °C
Note: Due to power dissipation, there is a difference
between the ambient temperature (TA) and
junction temperature. Please refer to section
4.1. on page 15 for details.
Latching Sensors:
The sensors have a latching behavior and require a
magnetic north and south pole for correct functioning.
The output turns low with the magnetic south pole on
the branded side of the package and turns high with
the magnetic north pole on the branded side. The
output does not change if the magnetic field is
removed. For changing the output state, the opposite
magnetic field polarity must be applied.
Hall Sensor Package Codes
HALXXXPA-T
Temperature Range: K
Package: TQ for SOT89B-3
JQ for TO92UA-5/6
Unipolar Switching Sensors with Inverted Output
Sensitive to North Pole:
Type: 2xy
The output turns high with the magnetic north pole on
the branded side of the package and turns low if the
magnetic field is removed. The sensor does not
respond to the magnetic south pole on the branded-
side.
Example: HAL202JQ-K
→ Type: 202
→ Package: TO92UA-6
→ Temperature Range: TJ = −40 °C to +140 °C
1.3. Marking Code
Hall sensors are available in a wide variety of packag-
ing versions and quantities. For more detailed informa-
tion, please refer to the brochure: “Hall Sensors.
Ordering Codes, Packaging, Handling”.
All Hall sensors have a marking on the package
surface (branded side). This marking includes the
name of the sensor and the temperature range.
1.5. Solderability and Welding
Type
Temperature Range
K
During soldering reflow processing and manual
reworking, a component body temperature of 260 °C
should not be exceeded.

Device terminals shall be compatible with laser and
electrical welding. Please, note that the success of the
welding process is subject to different welding parame-
ters which will vary according to the welding technique
used. A very close control of the welding parameters is
absolutely necessary in order to reach satisfying
results. Micronas, therefore, does not give any implied
or express warranty as to the ability to weld the com-
ponent.
