Product details
Overview
JANTXV1N4983DUS/TR from Microsemi is a military-grade, hermetically sealed surface-mount Zener diode rated for 5 W power dissipation at 140 °C end-cap temperature, with nominal Zener voltage of 110 V ±5%, dynamic impedance of 125 Ω at 12 mA test current, and operating junction temperature range from –65 °C to +175 °C. It serves as a precision voltage reference and overvoltage clamp in high-reliability power regulation circuits for aerospace and defense systems.
For engineers reviewing the JANTXV1N4983DUS/TR datasheet, JANTXV1N4983DUS/TR pinout, JANTXV1N4983DUS/TR application, or JANTXV1N4983DUS/TR equivalent, key selection criteria include its voidless-glass hermetic package, Category I metallurgical bond, radiation-hardened construction per MicroNote 050, and compliance with MIL-PRF-19500/356 Class V screening.
Technical Context
This device operates in reverse-bias breakdown mode to maintain stable voltage across wide current (10%–50% of IZM) and temperature ranges. Its Zener voltage exhibits a temperature coefficient of +0.100 %/°C and is specified with ΔVZ ≤ 9.0 V between 10% and 50% of maximum Zener current (IZM = 1.2 A).
The "E" package (D-5B) uses tungsten slugs and copper end caps with Sn/Pb finish, enabling direct solder attachment without adhesive. Thermal resistance is 7 °C/W junction-to-end-cap, supporting reliable 5 W operation under controlled thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 110 V ±5% at IZT = 12 mA - defines regulated output voltage under nominal bias |
| Power Dissipation | 5 W @ TEC = 140 °C - maximum continuous power before thermal derating begins |
| Dynamic Impedance (ZZ) | 125 Ω @ IZT = 12 mA - low AC impedance ensures minimal voltage variation under load transients |
| Max Reverse Leakage (IR) | 2 μA @ VR = 83.6 V - confirms tight leakage control near 76% of VZ, critical for low-power bias networks |
| Temp Coefficient (αVZ) | +0.100 %/°C @ IZT - positive drift enables predictable compensation in temperature-stable references |
| Surge Current (IZSM) | 1.2 A @ 8.3 ms - supports transient overvoltage clamping without degradation |
| Junction Temp Range | –65 °C to +175 °C - enables operation in extreme environments including space and engine bays |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4983US | No TR suffix; bulk packaging instead of tape-and-reel; identical electrical specs and screening | Preferred for manual prototyping or low-volume hand-soldered assemblies | Select JANTXV1N4983US when automated pick-and-place is not required and inventory control favors loose components |
| 1N4983US | Commercial-grade (non-military) version; lacks JAN/JANTXV screening, radiation hardening, and Category I bond validation | Suitable only for non-critical industrial applications with ambient temperatures <125 °C | Choose 1N4983US only if MIL-PRF-19500/356 compliance, extended temperature operation, or radiation tolerance are not required |
Compared with JANTXV1N4983DUS/TR, JANTXV1N4983US offers identical performance in tape-and-reel form factor but requires alternate logistics handling, while 1N4983US sacrifices military reliability attributes for cost reduction in benign environments.

FAQ
What is the Zener voltage tolerance and test current for JANTXV1N4983DUS/TR?
JANTXV1N4983DUS/TR has a nominal Zener voltage of 110 V with ±5% tolerance, measured at a test current (IZT) of 12 mA. This tolerance reflects the standard military-grade specification per MIL-PRF-19500/356, and no tighter tolerance suffix (e.g., 'C' or 'D') is applied to this specific part number. The 12 mA IZT ensures stable regulation within the device's optimal dynamic impedance region.
Does JANTXV1N4983DUS/TR require heatsinking in 5 W operation?
JANTXV1N4983DUS/TR is rated for 5 W dissipation at an end-cap temperature (TEC) of 140 °C, with a junction-to-end-cap thermal resistance of 7 °C/W. Heatsinking is required to maintain TEC ≤ 140 °C under full 5 W load; without thermal management, junction temperature will exceed safe limits. PCB copper area and optional adhesive mounting per D-5B pad layout enhance thermal transfer.
Is JANTXV1N4983DUS/TR compatible with lead-free reflow processes?
JANTXV1N4983DUS/TR features Sn/Pb terminations and is not qualified for lead-free reflow. Its end-cap finish is incompatible with peak temperatures >220 °C typical of Pb-free profiles. For RoHS-compliant designs, consult Microchip's qualified lead-free alternatives or verify compatibility through joint qualification testing before deployment.
What does the "DUS/TR" suffix indicate in JANTXV1N4983DUS/TR?
The "DUS" denotes the D-5B (E) hermetic glass surface-mount package; "TR" indicates tape-and-reel packaging per EIA-481-B. This distinguishes JANTXV1N4983DUS/TR from bulk-packaged variants like JANTXV1N4983US. The suffix confirms both physical form factor and automated assembly readiness without altering electrical or screening specifications.
How does JANTXV1N4983DUS/TR perform under radiation exposure?
JANTXV1N4983DUS/TR exhibits inherent radiation hardness per Microsemi MicroNote 050, with verified tolerance to total ionizing dose (TID) levels exceeding 100 krad(Si). This behavior stems from its voidless-glass hermetic construction and Category I metallurgical bond, making it suitable for low-earth orbit and avionics applications where single-event effects and cumulative dose must be mitigated.
