1SMB5913BT3 series 3 watt plastic surface mount Zener voltage regulators
The 1SMB5913BT3 series offers 3 W plastic surface‑mount Zener diodes with a voltage range of 3.3 V to 200 V, Class 3 (>16 kV) ESD protection, and a flat handling surface for accurate placement. Packages are void‑free, transfer‑molded plastic (CASE 403A) and are available in Pb‑free versions.
Electrical characteristics include maximum steady‑state power dissipation of 3 W at 75 °C, a maximum lead temperature of 260 °C for 10 s, and UL 94 V‑0 flammability rating. Detailed tables list Zener voltage, impedance, leakage current, and device markings for each part number, along with thermal resistance values and derating curves.
