Overview
The Microchip Technology 1N3033B-1/TR is a 1-watt glass case Zener diode qualified per MIL-PRF-19500/115. It features a hermetically sealed DO-41 package with tungsten slugs and metallurgically bonded construction. The nominal Zener voltage is 36 V at a test current of 7 mA, with a maximum dynamic impedance of 50 Ohms. It operates within a junction temperature range of -55°C to +175°C and exhibits a maximum reverse leakage current of 10 µA.
Feature Summary
- Hermetically sealed voidless hard glass package with tungsten slugs for high-reliability applications.
- Metallurgically bonded double plug construction ensuring structural integrity.
- Inherently radiation hard design suitable for demanding environments.
Applications
- Voltage regulation over broad operating current and temperature ranges.
- High-reliability military and aerospace electronic circuits.
- Reference voltage sources in radiation-hardened systems.
Procurement Notes
Verify the specific ordering suffix against the manufacturer's part nomenclature to confirm RoHS compliance status and exact qualification level (JAN, JANTX, or JANTXV). Ensure the procurement documentation explicitly references MIL-PRF-19500/115 qualification requirements. Confirm that the tape and reel packaging adheres to EIA-296 standards if applicable.
Selection Notes
Select this component when a 36 V breakdown voltage with 5% tolerance is required in a through-hole glass package. Consider the 1 W power dissipation limit and the -55°C to +175°C operating range. Verify that the 50 Ohm dynamic impedance meets circuit stability requirements. Compare against other series members like 1N3032B-1 or 1N3034B-1 if voltage adjustments are needed.
Part Context
This device belongs to the established 1N3016B-1 through 1N3045B-1 JEDEC registered series. It provides a wide selection of Zener voltages from 6.8 to 110 volts in the same DO-41 package form factor. The series is designed for applications requiring low reverse leakage currents and non-sensitive ESD characteristics.
Replacement Considerations
Equivalent parts include JAN1N3033B-1, JANTX1N3033B-1, and JANTXV1N3033B-1. These variants share identical electrical specifications but differ in reliability qualification levels. Commercial versions without the military prefix may also be compatible if environmental qualifications are not required.
FAQ
What is the maximum DC power dissipation rating?
The maximum DC power dissipation is rated at 1.0 W.
