The BSS44 is a silicon epitaxial planar PNP transistor manufactured by STMicroelectronics. It is housed in a JEDEC TO-39 metal can package and is designed for high-current switching and power applications up to 5 A.
Key electrical specifications include a collector-emitter breakdown voltage (VCEO) of -60 V minimum, collector-base breakdown voltage (VCBO) of -65 V minimum, and emitter-base breakdown voltage (VEBO) of -6 V minimum. The collector current rating is -5 A. DC current gain (hFE) ranges from 30 to 70 depending on test conditions, with a transition frequency of 80 MHz.
The device offers a total power dissipation of 5 W at case temperature ≤25°C and 0.87 W at ambient temperature ≤25°C. Thermal resistance junction-to-case is 35 °C/W and junction-to-ambient is 200 °C/W. The operating junction temperature range is -65 to 200 °C.
Packaging is through-hole mounting with a TO-205AD / TO-39-3 metal can package and a lead pitch of 5.08 mm. The supplier device package is TO-39.

Estimated market price range - modelled values for guidance only, not live distributor offers.
The minimum collector-emitter breakdown voltage (VCEO) is -60 V at I_B=0, I_C=-50 mA.
The nominal collector current (IC) is -5 A.
The BSS44 is available in a TO-205AD / TO-39-3 metal can through-hole package (supplier device package TO-39).
The maximum operating junction temperature is 200 °C, and the storage temperature range is -65 to 200 °C.
The RoHS status is listed as RoHS3 Compliant, but this is unverified and has low confidence.
