Overview of Microsemi 50 Watt Zener Diodes
Microsemi, a prominent semiconductor manufacturer with operational bases in Lawrence, MA, USA, and Ennis, Co. Clare, Ireland, provides the datasheet for the series of 50 Watt Zener Diodes qualified per MIL-PRF-19500/358 standards. The series includes part numbers from 1N3305B through 1N3350B as well as from 1N4549B through 1N4556B. These diodes offer voltage regulation across a diverse voltage range from 3.9V to 200V, making them suitable for various application requirements with military-grade options including JAN, JANTX, and JANTXV levels of qualification.
Features of Zener Diodes
The diodes are encapsulated in an industry-standard DO-5 (DO-203AB) package, featuring internal solder bond construction and a hermetically sealed design which is impervious to environmental degradation and ensures long-term reliability. Additionally, they are non-sensitive to ESD as specified by MIL-STD-750 Method 1020, and inherently radiation-hardened as described in Microsemi MicroNote 050, offering durability suitable for high-stress applications.
Applications and Benefits
These diodes are designed to regulate voltage across broad operating currents and temperature ranges, offering standard voltage tolerances of +/- 5%, while tolerances of +/-10%, +/-2%, and +/-1% are available with differentiated suffixes on part numbers. With reverse polarity options and the proven capacity to withstand electrostatic discharge (ESD) and radiation effects, these components stand to benefit sophisticated electronic systems where reliability and precision are critical.
Maximum Ratings and Mechanical Specifications
They are robust, with maximum junction and storage temperatures ranging from -65°C to +175°C, power derating above 75°C, a forward voltage of 1.5 Volts at 10A, and thermal resistance as low as 2.0°C/W. The datasheet specifies the diodes’ physical attributes, including the hexagonal stud case, corrosion-resistant finish, 15 grams weight, and clarifies that standard polarity is anode to case whereas reverse polarity (cathode to case) is indicated with an R suffix in the part number. For optimal integration into systems, the manufacturer offers additional mounting hardware options and recommends consulting for details.
