BRX44-BRX49
High-reliability discrete products
and engineering services since 1977
SILICON CONTROLLED RECTIFIER
FEATURES
Available as “HR” (high reliability) screened per MIL-PRF-19500, JANTX level. Add “HR” suffix to base part number.
Available as non-RoHS (Sn/Pb plating), standard, and as RoHS by adding “-PBF” suffix.

Note 1: VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate voltage; however, positive gate voltage shall not be applied concurrent with negative
potential on the anode. Blocking voltages shall not be tested with a constant current source such that the voltage ratings of the devices are exceeded.
