The 1N4554B is a Zener diode manufactured by Solid State Devices Inc (SSDI). It provides a nominal Zener voltage of 6.2V with a tolerance of ±10% and a power dissipation rating of 50W. The device exhibits a low Zener impedance of 0.14Ω, ensuring stable voltage regulation. Forward voltage is 1.5V at 10A, and reverse leakage current is 20µA at 2V.
The diode is housed in a rugged DO-203AB (DO-5) stud mount package, suitable for high-power applications requiring efficient heat dissipation. It supports an operating temperature range from -65°C to 175°C, making it suitable for extreme environments. The stud mount design allows for secure attachment to heatsinks.
Typical applications include voltage regulation, overvoltage protection, and reference voltage sources in power supplies and industrial equipment. The 1N4554B is RoHS3 compliant and REACH unaffected, with an MSL rating of 1 (unlimited).
