1N957B-992B (DO-35) 0.5W Zener Diodes datasheet, introducing the features and characteristics of the products.
This datasheet covers the 0.5 W silicon Zener diode series 1N957B‑1 through 1N992B‑1 in a DO‑35 (DO‑204AH) axial‑lead glass package. It lists the available voltage range from 6.8 V to 200 V, tolerance options, and the optional internal metallurgical‑bond version indicated by a “‑1” suffix.
Key electrical parameters such as Zener voltage, test current, impedance, reverse leakage and surge ratings are tabulated at 25 °C. Mechanical and packaging information includes dimensions, hermetic sealing, lead finish, and recommended soldering temperatures. Graphs illustrate power dissipation, temperature coefficients and capacitance versus voltage.
