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.
The package styles available provide magnetically optimized
solutions for most applications. Package LH is an SOT23W, a
miniature low-profile surface-mount package, while package UA
is a three-lead ultramini SIP for through-hole mounting. Each
package is available in a lead (Pb) free version, with 100% matte
tin plated leadframes.
