This document is the absolute maximum ratings datasheet for the 1N/FDLL 914/A/B / 916/A/B / 4148 / 4448 small signal diodes.
This datasheet provides the absolute maximum ratings, thermal and electrical characteristics, and typical performance curves for the Fairchild 1N/FDLL series small‑signal diodes (914/A/B, 916/A/B, 4148, 4448). It includes limits such as reverse voltage, forward current, power dissipation, and storage temperature range, as well as detailed graphs of forward voltage versus current and temperature.
Additional sections cover diode packaging, color‑band marking, trademark information, and product status definitions (pre‑production, full production, obsolete). The document is intended for designers and engineers who need precise diode parameters for circuit design and reliability analysis. This manual is written in Chinese.
