Product details
Overview
JAN1N4101C-1 from Microsemi is a 500 mW, 8.2 V ±2% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANTXV level per MIL-PRF-19500/435. It delivers stable voltage regulation across wide current and temperature ranges, with low dynamic impedance (200 Ω at 250 mA), minimal noise density (1 µV/√Hz), and radiation-hardened construction for aerospace and defense power-supply reference applications.
For engineers reviewing the JAN1N4101C-1 datasheet, JAN1N4101C-1 pinout, JAN1N4101C-1 application, or JAN1N4101C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), JANTXV reliability qualification, DO-35 axial-leaded hermetic packaging, thermal resistance (250 °C/W junction-to-lead), and low-noise performance critical for precision analog references and regulated bias networks.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining 8.2 V across its terminals when reverse-biased above breakdown with current between IZK (knee current) and IZM (maximum Zener current). Its metallurgical bond ensures mechanical stability under thermal cycling and shock, while hermetic glass sealing prevents moisture ingress and supports long-term parametric stability in harsh environments.
The JAN1N4101C-1 exhibits a positive temperature coefficient of +0.070 %/°C, enabling predictable drift compensation in multi-diode reference designs. Its low capacitance (<2 pF typical at 0 V) and minimal leakage (0.5 µA at 6.6 V) support high-frequency stability and low-error sensing in feedback loops of DC-DC converters and instrumentation amplifiers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4101US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads; RoHS-compliant matte-tin plating | Designed for automated SMT assembly; unsuitable for through-hole prototyping or manual repair | Select when board space is constrained and reflow soldering is available; verify thermal pad layout matches RθJL derating curve |
| JAN1N4101D-1 | Identical construction and qualification, but ±1% Zener voltage tolerance instead of ±2% | Used where tighter initial accuracy is required, e.g., calibration standards or metrology-grade references | Select only if ±1% tolerance is mandated; higher cost and longer lead time; no improvement in tempco or noise |
Compared with JAN1N4101C-1, the 1N4101US-1 offers identical regulation performance in a smaller footprint but requires SMT infrastructure, while JAN1N4101D-1 improves initial accuracy at the expense of availability and cost-neither is pin-compatible due to differing packages or tolerance-driven binning.

FAQ
What is the Zener voltage tolerance and test current for JAN1N4101C-1?
JAN1N4101C-1 has a nominal Zener voltage of 8.2 V with a ±2% tolerance, measured at a Zener test current (IZT) of 250 mA. This tolerance is achieved via post-manufacturing screening and binning, and the device maintains regulation within this band across its specified operating temperature range of –65 °C to +175 °C when properly heatsinked.
Is JAN1N4101C-1 suitable for surface-mount assembly?
No, JAN1N4101C-1 uses a DO-35 (DO-204AH) axial-leaded glass package and is intended for through-hole mounting. For surface-mount alternatives, consider the functionally equivalent 1N4101US-1 in DO-213AA package. Substituting JAN1N4101C-1 into an SMT footprint would require mechanical adaptation and invalidate its thermal and reliability ratings.
What does the "C" suffix signify in JAN1N4101C-1?
The "C" in JAN1N4101C-1 denotes a ±2% Zener voltage tolerance per the Microsemi part nomenclature. The full designation breaks down as: JAN = JANTXV reliability level, 1N4101 = JEDEC base type number (8.2 V), C = 2% tolerance, -1 = metallurgically bonded construction. This differs from JAN1N4101D-1 (±1%) and JAN1N4101-1 (±5%).
How is JAN1N4101C-1 qualified for high-reliability applications?
JAN1N4101C-1 is qualified to JANTXV level per MIL-PRF-19500/435, including rigorous screening: steady-state burn-in, temperature cycling (–65 °C to +150 °C), hermeticity testing (fine-and-gross leak), and electrical verification across temperature extremes. These tests ensure failure rates below 100 FIT for use in aerospace and defense systems with >10-year service life requirements.
What is the maximum Zener current (IZM) and how is it derived?
JAN1N4101C-1 has a maximum Zener current (IZM) of 40 mA, calculated from its 500 mW power rating and 8.2 V Zener voltage (P = V × I → I = 0.5 W / 8.2 V ≈ 61 mA), then conservatively derated to 40 mA to accommodate thermal resistance (RθJL = 250 °C/W) and ensure safe junction temperature rise under worst-case lead-length and ambient conditions.
