The 1N5939A is a 39V Zener diode from Microchip Technology, part of the 1N5913B-5956B series of 1.5 watt glass Zener diodes. It provides a Zener voltage of 39V with a tolerance of ±10% and a maximum impedance of 45Ω. The device can dissipate up to 1.5W steady-state power at a lead temperature of 85°C, or 1.25W at ambient temperature of 25°C. Forward voltage is 1.2V at 200mA, and reverse leakage current is 1µA at 29.7V.
The diode is housed in a through-hole DO-204AL (DO-41) axial-lead package, suitable for flexible mounting. It operates over a wide junction temperature range of -65°C to 175°C, with a thermal resistance of 60°C/W junction-to-lead and 120°C/W junction-to-ambient when mounted on FR4 board. The glass hermetically sealed construction offers enhanced reliability. The part is reported as RoHS3 compliant.
