MU4892 - SILICON UNIJUNCTION TRANSISTOR

Download the MU4892 datasheet PDF. This datasheet also covers the MU4891 variant, as both devices belong to the same silicon unijunction transistor family and are provided as variant models within a single manufacturer datasheet.

Key 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.

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.
