The 1N5255B-TR is a silicon planar power Zener diode from Vishay Dale designed for voltage stabilization applications. It features a nominal Zener voltage of 28V with a tolerance of ±5%, and a maximum power dissipation of 500mW at a lead temperature of 25°C.
This through-hole device is housed in a DO-35 (DO-204AH) axial package weighing approximately 125mg. It offers a maximum dynamic impedance of 44Ω at the Zener test current, and a maximum reverse leakage current of 100nA at 21V. The forward voltage is specified at 1.1V maximum at 200mA.
The diode operates over a wide temperature range from -65°C to 175°C, with a junction-to-ambient thermal resistance of 300K/W. The molding compound is rated UL 94 V-0 for flammability, and the device can withstand a peak soldering temperature of 260°C.
