Overview
The Microchip Technology 1N3315B is a high-power 50 W Zener diode within the 1N3305 through 1N3350B series. It provides voltage regulation with a nominal Zener voltage of 16.0 V at a test current of 780 mA. The device features a maximum dynamic impedance of 1.60 Ohms and a maximum reverse current of 10 µA. It operates within a junction temperature range of -65°C to +175°C and utilizes a DO-5 (DO-203AB) package.
Feature Summary
- Hermetically sealed welded metal and glass construction
- Internal solder bond design for reliability
- Inherently radiation hard characteristics
- ESD nonsensitive per MIL-STD-750 Method 1020
Applications
- High power voltage regulation
- Military and aerospace electronic systems
- Circuits requiring inherent radiation hardness
Procurement Notes
Verify the specific suffix configuration, as 'B' denotes a 5% tolerance while 'R' indicates reversed polarity. Confirm that the required thermal management supports the 50 W dissipation rating at the intended case temperature. Ensure the application environment aligns with the specified operating temperature range and radiation hardness requirements.
Selection Notes
Select this component when high power handling and ruggedness are critical. The DO-5 stud mount package facilitates direct heat sinking. Consider the +/- 5% tolerance if precision is required. Verify compatibility with the mounting hardware and insulators needed for the hexagonal base installation.
Part Context
This part belongs to the 1N3305 thru 1N3350B series of 50 Watt Zener diodes manufactured by Microsemi Scottsdale Division. These devices offer a broad voltage selection from 3.9 V to 200 V. They are designed for demanding applications where standard packages cannot handle the power dissipation or environmental stress.
Replacement Considerations
Equivalent parts include other 50 W Zener diodes in the DO-5 package with matching voltage and current ratings. Cross-reference with JAN, JANTX, or JANTXV qualified versions if military screening levels are necessary.
