1SMA5913BT3 is a 1.5 watt plastic surface mount zener voltage regulator.
The 1SMA5913BT3 Series offers 1.5 W plastic surface‑mount Zener diodes with a breakdown voltage range of 3.3 V to 68 V, Class 3 ESD rating (>16 kV), low‑profile packaging and a flat handling surface for accurate placement. The series is available in standard and Pb‑free packages and is suitable as a replacement for MELF devices.
The datasheet details electrical parameters such as maximum power dissipation (4.0 W at 25 °C), operating temperature range (‑65 °C to +150 °C), thermal resistance values, and typical characteristic curves. Mechanical dimensions for the SMA CASE 403D‑02 package are listed, along with ordering information for tape‑and‑reel and bulk shipments.
