Microchip Technology, Inc. Single Bipolar Transistors 2N3499UB/TR

The 2N3498 through 2N3501 series consists of NPN silicon transistors designed for high-reliability and general-purpose medium power applications requiring high-frequency switching. The devices are available in TO-39 (TO-205AD), TO-5, and U4 surface-mount packages, with hermetically sealed kovar-based construction and nickel-plated leads. The 2N3499 variant features a collector-emitter voltage rating of 100 V, a collector current of 500 mA, and a thermal resistance junction-to-ambient of 175 °C/W. The series meets MIL-PRF-19500/366 qualifications for JAN, JANTX, JANTXV, and JANS levels, and RoHS-compliant versions are available for commercial grade. Operating junction temperature ranges from -65 °C to +200 °C.
