Product details
Overview
1N3030C-1 from Microsemi is a 27 V, ±2% tolerance, 1 W hermetically sealed glass Zener diode in DO-41 package, rated for -55°C to +175°C operation, with 9.5 mA Zener test current, 35 Ω dynamic impedance at IZT, and 10 µA reverse leakage at 22.8 V. It serves as a precision voltage reference and regulator in high-reliability power supply feedback paths.
For engineers reviewing the 1N3030C-1 datasheet, 1N3030C-1 pinout, 1N3030C-1 application, or 1N3030C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), junction temperature range (-55°C to +175°C), DO-41 mechanical compatibility, MIL-PRF-19500/115 qualification level (JANTX), and radiation-hardened performance per MicroNote 050.
Technical Context
This device operates in reverse breakdown to maintain stable voltage across wide current (9.5 mA IZT to 35 mA IZM) and temperature (-55°C to +175°C) ranges. Its metallurgically bonded, double-plug DO-41 construction ensures hermetic sealing and low leakage (≤10 µA at VR = 22.8 V).
The 27 V nominal Zener voltage exhibits +0.096%/°C temperature coefficient and 35 Ω dynamic impedance at 9.5 mA, enabling predictable regulation in analog control loops and voltage-sensing circuits where stability under thermal stress is critical.

FAQ
What is the Zener voltage tolerance of the 1N3030C-1?
The 1N3030C-1 has a Zener voltage tolerance of ±2%, as indicated by the "C" suffix in its part number. This means its nominal 27 V Zener voltage falls within 26.46 V to 27.54 V at 9.5 mA test current and 25°C. The tighter tolerance reduces design margin requirements compared to ±5% (B suffix) or ±1% (D suffix) variants.
Is the 1N3030C-1 qualified to MIL-PRF-19500/115 standards?
Yes, the 1N3030C-1 is qualified to MIL-PRF-19500/115 at the JANTX level. This includes rigorous screening for vibration, thermal shock, and burn-in, confirming suitability for military and aerospace applications. The "JANTX" designation appears in the full part nomenclature and is documented in Microsemi T4-LDS-0285 Rev. 1.
What is the maximum reverse leakage current for the 1N3030C-1?
The 1N3030C-1 specifies a maximum reverse leakage current (IR) of 10 µA at VR = 22.8 V and 25°C. This low leakage ensures minimal error current in high-impedance reference circuits and contributes to stable regulation in battery-powered or low-quiescent-current systems.
Does the 1N3030C-1 have radiation-hardened characteristics?
Yes, the 1N3030C-1 is inherently radiation hard per Microsemi MicroNote 050, retaining electrical parameters after exposure to total ionizing dose (TID) up to 100 krad(Si). This property stems from its hermetic DO-41 glass package and metallurgical construction-not an add-on feature but intrinsic to the device physics.
What package type does the 1N3030C-1 use?
The 1N3030C-1 uses the DO-41 axial glass package with hermetic seal, tungsten slugs, and blue band marking the cathode. Its dimensions are BD = 0.080–0.107 inches, BL = 0.160–0.205 inches, and LL = 1.000 inches minimum, conforming to JEDEC standards and supporting manual or wave soldering at 260°C for 10 seconds.
