Product details
Overview
JAN1N4101C-1/TR from Microsemi is a 500 mW, 8.2 V ±2% tolerance, metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX level per MIL-PRF-19500/435, used for precision voltage regulation in military and aerospace power supply reference circuits.
For engineers reviewing the JAN1N4101C-1/TR datasheet, JAN1N4101C-1/TR pinout, JAN1N4101C-1/TR application, or JAN1N4101C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (200 Ω at 250 mA), noise density (1 μV/√Hz), temperature coefficient (+0.070 %/°C), and JANTX-level reliability qualification.
Technical Context
This device operates as a two-terminal reverse-biased voltage reference with a nominal Zener voltage of 8.2 V at 250 mA test current, exhibiting low dynamic impedance (200 Ω) and minimal capacitance (typical 46 pF). Its metallurgical bond construction ensures stable regulation across -65 °C to +175 °C junction temperature range.
The JAN1N4101C-1/TR delivers regulated output under varying load and temperature conditions with a positive temperature coefficient (+0.070 %/°C), enabling predictable drift compensation in analog reference designs. It is not a programmable or adjustable device - regulation occurs only in reverse breakdown mode with cathode band oriented toward higher potential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 8.2 V ±2% at 250 mA - defines precise regulation point for reference design stability |
| Power Dissipation | 500 mW @ 25 °C - supports continuous operation in compact axial-leaded layouts with linear derating above 50 °C |
| Dynamic Impedance ZZT | 200 Ω max at 250 mA - ensures minimal output voltage variation under load transients |
| Noise Density | 1 μV/√Hz - enables low-noise performance in precision analog references and sensor excitation |
| Temp. Coefficient αVZ | +0.070 %/°C - provides predictable, monotonic voltage drift for thermal compensation schemes |
| Reverse Leakage IR | 0.5 µA @ 6.3 V - guarantees tight regulation onset and low quiescent error in high-impedance bias networks |
| Junction Temp. Range | -65 °C to +175 °C - validated for extreme-environment operation in avionics and space-grade systems |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-leaded glass package with tin-lead plating; cathode indicated by single black band; weight ≈ 0.2 g; body diameter 1.42–2.29 mm, length 3.56–5.08 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lower-potential rail; must remain at lower voltage than cathode during regulation |
| Cathode | Regulated output node | Banded end; supplies stable 8.2 V when reverse-biased; requires current-limiting resistor in series |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTX qualification | Validated reliability for defense/aerospace use with full lot traceability and screening per military standards |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal cycling, ensuring long-term parameter stability |
| Low noise density (1 μV/√Hz) | Enables use in high-resolution ADC references and low-drift op-amp biasing without added filtering |
| Hermetic glass encapsulation | Prevents moisture ingress and parameter shift over decades in harsh environments |
| ±2% Zener tolerance (C suffix) | Reduces calibration burden in production test vs. standard ±5% parts; supports tighter system tolerances |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4101US-1/TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when board space is constrained and automated placement is available |
| JAN1N4101D-1/TR | Identical construction and qualification, but ±1% Zener tolerance (D suffix) instead of ±2% | Higher cost and longer lead time; justified only where system-level tolerance budget demands sub-2% reference accuracy | Select only if calibration budget requires < ±0.16 V absolute error at 8.2 V |
Compared with 1N4101US-1/TR and JAN1N4101D-1/TR, the JAN1N4101C-1/TR balances JANTX reliability, ±2% tolerance, and axial-leaded DO-35 compatibility - making it optimal for legacy military hardware upgrades and mixed-technology boards where leaded components coexist with SMT.

FAQ
What is the Zener voltage tolerance of JAN1N4101C-1/TR?
The JAN1N4101C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its actual breakdown voltage falls within 8.036 V to 8.364 V at 250 mA test current and 25 °C, enabling tighter system-level calibration than standard ±5% Zeners. The tolerance is verified per MIL-PRF-19500/435 screening.
Is JAN1N4101C-1/TR RoHS compliant?
No, JAN1N4101C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4101C-1e3); military-qualified parts like JAN1N4101C-1/TR retain tin-lead plating per MIL-STD-750 and are exempt from RoHS requirements due to reliability and solderability mandates for high-reliability applications.
What does the "TR" suffix indicate in JAN1N4101C-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JAN1N4101C-1/TR contains the same JANTX-qualified die and DO-35 package as JAN1N4101C-1, with identical electrical and reliability specifications - the only difference is packaging format for volume manufacturing.
What is the maximum Zener current IZM for JAN1N4101C-1/TR?
The maximum Zener current IZM for JAN1N4101C-1/TR is 40 mA, derived from its 500 mW power rating and 8.2 V nominal Zener voltage (P = V × I → I = 0.5 W / 8.2 V ≈ 61 mA, but datasheet specifies 40 mA as absolute maximum to maintain regulation integrity and thermal margin under worst-case derating).
How is polarity marked on JAN1N4101C-1/TR?
Polarity is marked by a single black cathode band on the glass body of JAN1N4101C-1/TR. The banded end is the cathode and must be connected to the higher-potential node for reverse-bias Zener operation; the unmarked end is the anode and connects to ground or lower potential. This marking complies with JEDEC DO-35 standards and MIL-PRF-19500/435 requirements.
