For engineers reviewing the JANTXV1N4102C-1/TR datasheet, JANTXV1N4102C-1/TR pinout, JANTXV1N4102C-1/TR application, or JANTXV1N4102C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (1 µV/√Hz), dynamic impedance (200 Ω), temperature coefficient (+0.075 %/°C), and military-grade qualification.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 8.7 V at 250 mA test current, exhibiting low dynamic impedance (200 Ω) and minimal capacitance per Figure 3. Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
Designed for high-reliability environments, JANTXV1N4102C-1/TR features a +0.075 %/°C temperature coefficient, 1 µV/√Hz noise density at IZT, and reverse leakage ≤0.5 µA at 7.0 V - enabling stable reference generation in analog signal chains and power supply feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 8.7 V ±2% at 250 mA - precise regulation point for feedback networks requiring tight voltage references. |
| Power Dissipation | 500 mW - supports continuous operation up to 25 °C ambient before linear derating begins at 50 °C. |
| Dynamic Impedance ZZT | 200 Ω - low AC impedance ensures minimal output voltage variation under load transients. |
| Noise Density | 1 µV/√Hz - ultra-low broadband noise critical for precision analog references and sensor excitation circuits. |
| Temp Coefficient αVZ | +0.075 %/°C - predictable positive drift enables accurate thermal compensation in reference designs. |
| Reverse Leakage IR | ≤0.5 µA @ 7.0 V - negligible standby current preserves efficiency in low-power biasing applications. |
| Junction Temp Range | –65 to +175 °C - validated for extreme-environment operation in avionics and space-grade electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4102US-1/TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Requires PCB redesign for SMT assembly; unsuitable for through-hole prototyping or legacy board rework. | Select when automated assembly, space-constrained layouts, or vibration resistance are prioritized over manual serviceability. |
| JANTXV1N4102D-1/TR | Identical construction and package, but ±1% Zener tolerance (D suffix) instead of ±2% (C suffix). | Higher precision at increased cost; used only where tighter regulation is mandated by system-level accuracy budgets. | Select only if system specification requires <±0.5% total reference error over temperature and life. |
Compared with JANTXV1N4102C-1/TR, the US-1/TR variant trades axial mounting flexibility for SMT manufacturability, while the D-1/TR variant adds ±1% tolerance at higher unit cost - neither offers pin-compatible replacement without layout or spec revision.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4102C-1/TR?
JANTXV1N4102C-1/TR has a nominal Zener voltage of 8.7 V with a ±2% tolerance (C suffix), measured at 250 mA test current and 25 °C. This tolerance is verified per MIL-PRF-19500/435 and applies across the full qualified temperature range of –65 to +175 °C junction temperature.
Is JANTXV1N4102C-1/TR RoHS compliant?
No, JANTXV1N4102C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (blank reliability level); JANTXV-level parts like JANTXV1N4102C-1/TR use tin-lead plating per MIL-STD-750 and are exempt from RoHS requirements due to their military qualification status.
What is the maximum Zener current IZM for JANTXV1N4102C-1/TR?
The maximum Zener current IZM for JANTXV1N4102C-1/TR is 40 mA, derived from its 500 mW power rating and 8.7 V Zener voltage (P = V × I → I = 0.5 W / 8.7 V ≈ 57 mA), with derating applied per Figure 2 to maintain safe junction temperature under real-world thermal conditions.
Does JANTXV1N4102C-1/TR have radiation-hardened characteristics?
Yes, JANTXV1N4102C-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and JANTXV qualification per MIL-PRF-19500/435 provide proven resilience against total ionizing dose (TID) and single-event effects in space and nuclear environments.
What does the "TR" suffix indicate in JANTXV1N4102C-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTXV1N4102C-1/TR is supplied in reels optimized for high-volume manufacturing, with lead-free solder compatibility confirmed per MIL-STD-750 Method 2026.
