1.5 Watt Plastic Surface Mount Zener Voltage Regulators
The 1SMA5913BT3 series offers 1.5 W plastic surface‑mount Zener diodes with a standard breakdown voltage range of 3.3 V to 68 V, Class 3 ESD rating (>16 kV), flat handling surface, low‑profile package and Pb‑free options. Features include top‑slide or bottom‑circuit‑board mounting and suitability as a replacement for MELF packages.
The datasheet lists electrical characteristics such as maximum power dissipation (1.5 W at 75 °C, 0.5 W at 25 °C), thermal resistance, operating temperature range (‑65 °C to +150 °C), and detailed Zener voltage versus current curves. Mechanical data, package dimensions, ordering codes and contact information are also provided.
