For engineers reviewing the JANTXV1N4626D-1/TR datasheet, JANTXV1N4626D-1/TR pinout, JANTXV1N4626D-1/TR application, or JANTXV1N4626D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification details critical for precision reference and ruggedized analog design.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 5.6 V at 250 mA test current, exhibiting a temperature coefficient of –0.020 %/°C to +0.040 %/°C and dynamic impedance of 1400 Ω at IZT. Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
Designed for high-reliability environments, JANTXV1N4626D-1/TR meets MIL-PRF-19500/435 requirements up to JANTXV level, features hermetically sealed DO-35 glass packaging, and delivers low noise density (≤4 μV/√Hz typical) - optimized for low-drift analog references and precision biasing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.6 V ±1% at 250 mA - enables precise voltage clamping and reference generation with tight initial accuracy. |
| Power Dissipation | 500 mW at 25 °C - supports stable operation in compact, unheatsinked analog circuits with linear derating above 50 °C. |
| Dynamic Impedance ZZT | 1400 Ω at IZT - ensures minimal output voltage variation under load current changes in feedback and reference paths. |
| Temperature Coefficient αVZ | –0.020 to +0.040 %/°C - provides predictable, low-drift regulation over –65 to +175 °C operating range. |
| Noise Density ND | ≤4 μV/√Hz at IZT - critical for low-noise analog references in instrumentation and signal conditioning stages. |
| Reverse Leakage IR | ≤4.0 μA at VR = 4.0 V - guarantees minimal quiescent current draw in high-impedance bias networks. |
| Max Zener Current IZM | 65 mA - defines safe continuous operating limit before thermal runaway under full-rated power conditions. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by band; banded end is positive during Zener regulation. Hermetically sealed, tin-lead plated leads solderable per MIL-STD-750 method 2026.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4626US-1 | 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 legacy board repair. | Select when automated placement and space-constrained layouts are prioritized over manual serviceability. |
| JANTXV1N4626-1 | Identical Zener voltage and qualification level, but ±5% tolerance instead of ±1%. | Higher initial voltage uncertainty requires tighter external compensation or calibration in precision references. | Choose only if cost sensitivity outweighs accuracy requirements and system-level trimming is available. |
Compared with JANTXV1N4626D-1/TR, the 1N4626US-1 offers identical regulation performance in a smaller footprint but eliminates field-replaceability, while JANTXV1N4626-1 trades 1% accuracy for lower unit cost - making JANTXV1N4626D-1/TR optimal for untrimmed, high-stability analog references where initial accuracy directly impacts system calibration burden.

FAQ
What is the Zener voltage tolerance of JANTXV1N4626D-1/TR?
JANTXV1N4626D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This tight tolerance ensures initial accuracy of 5.6 V within ±0.056 V at 250 mA test current, eliminating need for post-production calibration in many high-reliability analog designs.
Is JANTXV1N4626D-1/TR RoHS compliant?
No, JANTXV1N4626D-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions of this family; JANTXV-level parts retain tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability under extreme thermal cycling, and are exempt from RoHS restrictions under applicable defense exemptions.
What is the maximum operating temperature for JANTXV1N4626D-1/TR?
JANTXV1N4626D-1/TR has a junction and storage temperature range of –65 °C to +175 °C, validated per MIL-PRF-19500/435. Its thermal resistance junction-to-ambient is 300 °C/W on FR4 board, and it linearly derates from 500 mW at 25 °C to zero at 175 °C - supporting operation in high-temperature avionics and engine-mounted electronics.
How does the temperature coefficient of JANTXV1N4626D-1/TR affect long-term stability?
JANTXV1N4626D-1/TR exhibits a temperature coefficient of –0.020 %/°C to +0.040 %/°C, meaning its Zener voltage shifts by less than ±0.00224 V over a 40 °C change. This low TC, combined with metallurgical bond construction, ensures <0.1% total drift over –55 to +125 °C - critical for uncalibrated reference stability in field-deployed systems.
Can JANTXV1N4626D-1/TR be used as a replacement for JANTXV1N4626-1?
Yes, JANTXV1N4626D-1/TR can functionally replace JANTXV1N4626-1 in most circuits, but with improved accuracy: both share identical Zener voltage (5.6 V), JANTXV qualification, and DO-35 package, yet JANTXV1N4626D-1/TR adds ±1% tolerance versus ±5% for JANTXV1N4626-1 - delivering higher initial precision without layout or thermal changes.
