1N5258B-T

Single Zener Diodes Overview

The Vishay General Semiconductor - Diodes Division 1N5258B-T is a silicon planar power Zener diode housed in the DO-35 (DO-204AH) axial through-hole package. It provides a nominal Zener voltage of 36 V with a standard tolerance of ±5%, indicated by the 'B' suffix. The device operates at a test current of 3.4 mA and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 100 nA, a dynamic impedance of 70 Ω, and a typical temperature coefficient of 0.093 %/K.
