Active production — 36 V, 500 mW Zener in DO-35
The 1N6013A: The ±10% tolerance on the 36 V nominal Zener voltage covers the full operating range; for a 36 V rail clamp, the actual breakdown sits between 32.4 V and 39.6 V.
Temperature range and leakage — -65°C to 175°C, 100 nA max
Operating from -65°C to 175°C, this diode suits high-temperature environments like engine-bay electronics or industrial sensor heads where standard 85°C or 125°C parts would derate.
Package and board integration — DO-35 axial, through hole
The DO-35 (DO-204AH) axial package with 0.020-inch diameter leads mounts into standard 0.035-inch plated through holes on a single-sided or double-sided board. Supplied in bulk — no tape-and-reel — so it is handled as loose parts for manual insertion or tube-fed for selective-wave soldering; the axial form factor is common in point-to-point wiring and breadboard prototyping.
Forward drop and impedance — 1.1 V at 200 mA, 130 Ω max
Maximum forward voltage is 1.1 V at 200 mA forward current — the diode conducts as a standard silicon rectifier in the forward quadrant, useful for reverse-polarity protection in low-current paths. Maximum Zener impedance (Zzt) is 130 Ω at the test current — this sets the dynamic resistance the load sees; a 36 V rail with 10 mA load variation shifts the output by about 1.3 V due to the impedance alone.
