A3245
Description (continued)
patented magnetic-polarity-independence feature makes this device
an excellent replacement for reed switches, with improved ease of
manufacturing, because the A3245 does not require manufacturers
to orient their magnets. These devices allow simple on/off switching
in industrial, consumer, and automotive applications.
The A3245 is rated for operation between the ambient temperatures

–40°C and 85°C for the E temperature range, and –40°C to 150°C
for the L temperature range. The small geometries of the BiCMOS
process allow these devices to be provided in ultrasmall packages.
Package LH is an SOT23W, a miniature low-profile surface-
mount package. It is lead (Pb) free, with 100% matte tin plated
leadframe.
