Product details
Overview
JANTXV1N4983CUS/TR from Microsemi is a surface-mount, voidless-hermetically-sealed glass Zener diode rated for 5 W power dissipation at 140 °C end-cap temperature, with a nominal Zener voltage of 110 V ±2% (C suffix), dynamic impedance of 125 Ω at 12 mA test current, and maximum reverse leakage of 2 μA at 83.6 V - deployed in high-reliability military power regulation and voltage reference circuits.
For engineers reviewing the JANTXV1N4983CUS/TR datasheet, JANTXV1N4983CUS/TR pinout, JANTXV1N4983CUS/TR application, or JANTXV1N4983CUS/TR equivalent, this part delivers MIL-PRF-19500/356 qualified performance across -65 °C to +175 °C, with Category I metallurgical bonding, triple-layer passivation, and ESD immunity per MIL-STD-750 Method 1020.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, maintaining stable output voltage over wide current (12 mA to 930 mA) and temperature (-65 °C to +175 °C) ranges. Its voidless-glass hermetic seal and tungsten slug construction ensure long-term reliability under thermal cycling and radiation exposure.
The JANTXV1N4983CUS/TR exhibits a temperature coefficient of +0.100 %/°C at 12 mA, low dynamic impedance (125 Ω), and tight 2% voltage tolerance - enabling use in critical analog references where drift and noise must be minimized without active compensation.

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/TR | Same 110 V rating but ±5% tolerance (no C suffix); higher max leakage (5 μA at 83.6 V). | Suitable for non-critical biasing where tighter tolerance is unnecessary. | Select JANTXV1N4983CUS/TR when 2% initial accuracy and lower leakage are required for metrology-grade references. |
| CDLL110 | 110 V, ±5%, 5 W, plastic surface-mount package; no hermetic seal or MIL qualification. | Limited to commercial/industrial environments with benign temperature and humidity profiles. | Choose CDLL110 only for cost-sensitive, non-mission-critical designs where radiation hardness and -65 °C operation are not needed. |
Compared with JANTXV1N4983US/TR and CDLL110, the JANTXV1N4983CUS/TR uniquely combines 2% tolerance, hermetic voidless-glass construction, Category I bonding, and full MIL-PRF-19500/356 qualification - making it the sole option for flight-critical, radiation-exposed, or extended-temperature deployments.

FAQ
What is the Zener voltage tolerance of JANTXV1N4983CUS/TR?
The JANTXV1N4983CUS/TR has a nominal Zener voltage of 110 V with a ±2% tolerance, indicated by the "C" suffix per Microsemi's standard coding. This tighter tolerance is achieved through post-manufacture screening and is verified at 12 mA test current and 25 °C ambient. The JANTXV1N4983CUS/TR maintains this accuracy across its full operating temperature range.
Does JANTXV1N4983CUS/TR require derating above 140 °C?
Yes - JANTXV1N4983CUS/TR is rated for 5 W dissipation only at an end-cap temperature (TEC) of 140 °C. Above that, power must be linearly derated to zero at 175 °C junction temperature. Derating follows a slope of 0.0357 W/°C (5 W ÷ 140 °C), meaning at 150 °C TEC, maximum allowable power drops to 4.64 W. Thermal design must account for the 7 °C/W junction-to-end-cap resistance.
Is JANTXV1N4983CUS/TR compatible with lead-free solder reflow?
No - JANTXV1N4983CUS/TR features tin/lead (Sn/Pb) terminations and is not qualified for lead-free reflow profiles. Its end caps are specified with Sn/Pb finish, and the glass-to-metal seal is optimized for eutectic solder thermal profiles. Lead-free reflow (peak >260 °C) risks cracking the voidless glass envelope or degrading the metallurgical bond. Use only Sn63/Pb37 or equivalent eutectic processes.
What does the "JANTXV" prefix signify for JANTXV1N4983CUS/TR?
The "JANTXV" prefix on JANTXV1N4983CUS/TR denotes compliance with MIL-PRF-19500/356 Class V requirements: full lot traceability, 100% electrical screening, burn-in, and rigorous environmental testing including thermal shock, vibration, and hermeticity validation. It exceeds JANTX-level screening and is approved for spaceflight and nuclear applications where failure is unacceptable.
Can JANTXV1N4983CUS/TR be used in forward conduction mode?
Yes - JANTXV1N4983CUS/TR has a specified forward voltage of 1.50 V at 1.0 A, consistent with standard silicon PN junction behavior. However, its design intent and qualification are strictly for reverse-bias Zener regulation. Forward conduction is not screened or guaranteed for reliability; using it as a rectifier or switch violates its MIL-PRF-19500/356 qualification scope and voids warranty.
