Microsemi Corp. Bipolar Transistors - BJT Jantxv2N3498/TR

The Jantxv2N3498/TR is a military-qualified NPN silicon transistor from the 2N3498 through 2N3501 series, designed for high-reliability and medium-power applications requiring high-frequency switching. It is housed in a TO-39 (TO-205AD) hermetically sealed package with a kovar base and nickel cap, measuring 7.75 to 8.51 mm in diameter and 6.10 to 6.60 mm in height. The device has 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. Operating junction temperature ranges from -65 to +200 °C. It is qualified per MIL-PRF-19500/366 at JANTXV level and features lead finishes compliant with military specifications. The series meets RoHS requirements in commercial grade variants, though this specific variant is not marked as RoHS compliant.
