MU4891-MU4894 High-reliability discrete products and engineering services since 1977 SILICON UNIJUNCTION TRANSISTOR 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. MAXIMUM RATINGS. Rating Symbol Value Power dissipation(1) PD 300 RMS emitter current IE 50 Peak pulse emitter current (2) iE 1.0 Emitter reverse voltage VB2E 30 Storage temperature range Tstg -65 to 150 Note 1: Derate 3mW/°C increase in ambient temperature. The total power dissipation must be limited by the external circuitry. VB2B1 = √(RBB · PD) Note 2: Capacitance discharge must fall to 0.37 Amp within 3.0ms and PRR ≤ 10PPS.
