1N5368B DIODE ZENER 47V 5W
The 1N5368B is a rugged, axial-leaded silicon Zener diode specified for a nominal Zener voltage of 47 V and a rated power dissipation of 5 W. Supplied in a DO-201AD molded plastic case, it’s built for applications requiring a stable reference or clamp at relatively high Zener voltages while withstanding substantial reverse power during transients. The device family covers a wide voltage range (5.1–200 V), and the 1N5368B is positioned toward the higher-voltage, medium-power end of that series.
Mechanically the diode features plated, solderable leads and a compact DO-201AD body, with thermal derating behavior shown for various lead-to-heatsink conditions in the datasheet. The part is designed for reliable thermal performance when mounted appropriately (lead length and heat-sink practices affect the allowable dissipation), and the datasheet gives thermal resistance and derating curves to help designers maintain safe junction temperatures.
Electrically the 1N5368B provides a predictable 47 V clamp/reference at the specified test current, with conservative impedance and leakage characteristics chosen to maintain voltage stability under load. Its limits on forward voltage, reverse leakage and storage/junction temperatures reflect a design aimed at long life and low leakage in high-voltage biasing, regulation, and protection roles. The datasheet emphasizes low leakage, high peak reverse dissipation capability and broad operating temperature range for dependable service.
