2.7 V Zener, 500 mW — DO-35 axial
The 1N6310 is a 2.7 V Zener diode in a DO-35 axial-lead package, rated for 500 mW continuous power dissipation. The ±5% tolerance on the nominal voltage means the actual Zener voltage sits between 2.565 V and 2.835 V at the test current — tight enough for most reference and clamping applications in this voltage class. This makes the 1N6310 suitable for avionics, missile guidance, satellite, and downhole equipment where the junction sees extreme thermal cycling. Maximum Zener impedance (Zzt) is 30 Ohms at the test current — a moderate dynamic resistance that keeps the regulation slope within a few millivolts per milliamp of load change. Reverse leakage is specified at 60 µA max at 1 V reverse bias, confirming the junction blocks cleanly below the breakdown knee.
Active lifecycle — sourcing posture
The DO-35 axial package is a standard through-hole format — no special handling or moisture sensitivity. The part ships in bulk packaging as listed.
