Product details
Overview
JANTX1N4102C-1/TR from Microsemi is a 500 mW, 8.7 V ±2% metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4102C-1/TR datasheet, JANTX1N4102C-1/TR pinout, JANTX1N4102C-1/TR application, or JANTX1N4102C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), low dynamic impedance (200 Ω @ 250 mA), temperature coefficient (+0.075 %/°C), and hermetic DO-35 packaging for stable operation across -65°C to +175°C.
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 a positive temperature coefficient of +0.075 %/°C - critical for thermal stability in regulated reference circuits. Its metallurgical bond construction ensures low noise density (1 µV/√Hz) and minimal capacitance per Figure 3.
The JANTX qualification confirms compliance with MIL-PRF-19500/435 for high-reliability applications, including radiation-hardened environments per MicroNote 050. It is rated for 500 mW average power dissipation with linear derating from 25°C ambient to zero at 175°C on standard FR4 PCB layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 8.7 V ±2% at IZT = 250 mA - enables precise reference generation in analog monitoring and feedback loops. |
| Power Dissipation | 500 mW @ TL = 25°C, derated linearly to zero at 175°C - supports continuous operation in high-temp avionics enclosures. |
| Zener Impedance ZZT | 200 Ω max @ 250 mA - ensures tight regulation under varying load conditions without external compensation. |
| Reverse Leakage IR | 0.5 µA max @ VR = 7.0 V - minimizes quiescent current draw in battery-backed systems. |
| Temp Coefficient αVZ | +0.075 %/°C - provides predictable, monotonic drift for calibration-critical references. |
| Noise Density | 1 µV/√Hz - suitable for low-noise analog front-ends and precision ADC reference buffers. |
| Junction Temp Range | -65°C to +175°C - validated for extended-range operation in space-grade and engine-mounted electronics. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package; cathode indicated by band; banded end is anode when used in forward bias, but functions as cathode (positive terminal) during Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Zener cathode connection | Connected to higher potential node; reverse-biased operation requires this terminal to be more positive than cathode. |
| Cathode (non-banded end) | Zener anode connection | Connected to lower potential (e.g., ground or return path); establishes reference voltage at anode terminal. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTX qualification | Validated reliability for mission-critical aerospace and defense systems with full traceability and screening. |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal cycling, ensuring long-term parameter stability. |
| ±2% Zener voltage tolerance (C suffix) | Reduces need for post-production trimming in precision reference designs, lowering BOM and test cost. |
| Hermetic glass DO-35 package | Prevents moisture ingress and parameter drift over decades - essential for unattended field-deployed systems. |
| Low noise density (1 µV/√Hz) | Enables use in high-resolution sensor signal conditioning without added filtering or shielding. |

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 | Same electrical specs, but in surface-mount DO-213AA package; no axial leads. | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention. | Select when board space is constrained and automated assembly is used. |
| JAN1N4102C-1 | Identical electrical and mechanical specs, but qualified only to JAN level (less stringent screening than JANTX). | Approved for commercial/military hybrid systems where full JANTX screening is not mandated by program requirements. | Select when cost sensitivity outweighs need for extended burn-in and radiation testing. |
Compared with JANTX1N4102C-1/TR, the 1N4102US-1 offers footprint reduction at the expense of mechanical robustness, while JAN1N4102C-1 delivers identical performance with reduced reliability assurance - enabling trade-offs between lifecycle cost, assembly method, and mission assurance level.

FAQ
What is the Zener voltage tolerance of JANTX1N4102C-1/TR?
JANTX1N4102C-1/TR has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number. This is tighter than the standard ±5% (blank suffix) and supports precision reference applications without post-manufacturing calibration. The 8.7 V nominal value is guaranteed across the full operating temperature range when tested per MIL-PRF-19500/435.
Is JANTX1N4102C-1/TR RoHS compliant?
No, JANTX1N4102C-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for JANTX-qualified devices. The JANTX1N4102C-1/TR uses tin-lead plating per MIL-STD-750 and is intended for legacy and high-reliability programs where leaded finishes are required.
What does the "TR" suffix mean in JANTX1N4102C-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTX1N4102C-1/TR is supplied in reels for high-volume manufacturing, whereas the base part JANTX1N4102C-1 is typically supplied in bulk or ammo pack. Tape-and-reel configuration maintains full JANTX qualification and traceability.
What is the maximum Zener current IZM for JANTX1N4102C-1/TR?
The maximum Zener current IZM for JANTX1N4102C-1/TR is 6.7 mA, derived from its 500 mW power rating and 8.7 V Zener voltage (IZM = PM(AV)/VZ). This value assumes operation at 25°C ambient; actual usable current decreases with rising temperature due to linear derating per Figure 2 in the datasheet.
How is polarity marked on JANTX1N4102C-1/TR?
JANTX1N4102C-1/TR uses a single black band to mark the cathode terminal. During Zener regulation, the banded end must be connected to the more positive potential - i.e., it functions as the cathode despite the band conventionally indicating cathode in forward bias. This polarity marking is consistent across all DO-35 Zener diodes in the 1N4099–1N4135 family.
