Overview
The Microchip Technology 1N3335B is a high-power 50 W Zener diode with a nominal voltage of 62.0 V and a maximum dynamic impedance of 7 Ω at the test current of 200 mA. It operates within a junction temperature range of -65 °C to +175 °C and features a DO-5 (DO-203AB) metal-glass package with an anode-to-case standard polarity.
Feature Summary
- Hermetically sealed welded construction with internal solder bond design
- Inherently radiation hard per Microsemi MicroNote 050
- Non-sensitive to electrostatic discharge per MIL-STD-750 Method 1020
Applications
- Voltage regulation in broad operating current and temperature ranges
- High power dissipation applications requiring adequate mounting and heat sinking
- Military qualification environments utilizing JAN, JANTX, or JANTXV screening levels
Procurement Notes
Verify that the specific part number matches the required tolerance suffix, as the 'B' suffix indicates a +/- 5% Zener Voltage tolerance. Confirm whether standard anode-to-case polarity or reverse polarity (indicated by an 'R' suffix) is needed for the circuit design. Ensure the procurement documentation specifies the desired military screening level if applicable.
Selection Notes
Select this component when a 62 V breakdown voltage with tight +/- 5% tolerance is required. The device supports up to 50 W of DC power dissipation provided the case temperature remains below 75 °C. Consider the low thermal resistance of 2.0 °C/W maximum junction-to-hexagonal base for effective heat management in the final assembly.
Part Context
This device belongs to the JEDEC registered 1N3305 thru 1N3350B series manufactured by Microsemi's Scottsdale Division. The series provides voltage regulation across a broad range from 3.9 V to 200 V. These components are also available in various military qualifications including JAN, JANTX, and JANTXV per MIL-PRF-19500/358.
Replacement Considerations
Consult the manufacturer for surface mount equivalents. Verify compatibility with existing thermal management solutions due to the 50 W power rating and hexagonal stud mounting requirements.
