100 V Zener — voltage regulation and thermal budget
The 1N6024B/TR: The 100 V nominal Zener voltage with ±5% tolerance means the regulation point sits between 95 V and 105 V — a tight enough window for clamping supply rails or providing a stable reference in a high-voltage bias circuit. Rated for 500 mW maximum power dissipation, the DO-35 axial body conducts heat through the leads into the board copper; the actual power handling depends on the trace width and ambient temperature, with the -65°C to 175°C junction range providing margin for military-temperature or engine-bay environments. The 500 Ohm maximum Zzt impedance at the Zener knee means the voltage shifts about 0.5 V per mA of Zener current — a 5 mA bias current keeps the regulation within the ±5% tolerance band across the full operating temperature.
Leakage and forward conduction — off-state and surge behavior
Reverse leakage is specified at 100 nA maximum at 76 V reverse voltage — 24 V below the nominal Zener point — so the standby power loss in a voltage-clamp application is negligible, under 10 µW.
DO-35 axial package — board integration
The DO-204AH (DO-35) axial-lead package with through-hole mounting suits point-to-point wiring or PCB insertion where the leads are bent and soldered into plated holes — the 0.020-inch lead diameter fits standard 0.040-inch drill sizes. Supplied in Tape & Reel format, the 1N6024B/TR variant is intended for automated insertion equipment; the reel quantity and lead form are set for machine handling, not hand assembly.
