Product details
Overview
JANTXV1N4961CUS/TR from Microsemi is a military-grade, voidless-hermetically sealed surface-mount Zener diode rated for 5 W power dissipation at 140 °C end-cap temperature. It provides precise 13 V nominal regulation at 100 mA test current (IZT), with ±1% voltage tolerance (C suffix), dynamic impedance of 3.0 Ω at IZT, and operates across –65 °C to +175 °C junction temperature range. It serves as a high-reliability voltage reference in radiation-hardened avionics power conditioning circuits.
For engineers reviewing the JANTXV1N4961CUS/TR datasheet, JANTXV1N4961CUS/TR pinout, JANTXV1N4961CUS/TR application, or JANTXV1N4961CUS/TR equivalent, this page delivers verified electrical parameters, MIL-PRF-19500/356 qualification status, thermal resistance (7 °C/W), surge current rating (16 A @ 8.3 ms), and hermetic glass package construction details critical for aerospace and defense design validation.
Technical Context
This device belongs to Microsemi's JANTXV-qualified 1N49xxUS series, featuring voidless hard-glass encapsulation with tungsten slugs and copper end caps with Sn/Pb finish. Its Category I metallurgical bond ensures mechanical robustness under thermal cycling and shock, while triple-layer passivation enhances long-term stability in high-humidity environments.
The JANTXV1N4961CUS/TR exhibits a temperature coefficient of ±0.08 %/°C at IZT, enabling stable regulation over wide ambient ranges. Its low dynamic impedance (3.0 Ω) and tight 1% tolerance support precision feedback loops in regulated DC-DC converters where output accuracy and load transient response are mission-critical.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4961DUS/TR | Same 13 V nominal, ±2% tolerance (D suffix), identical package and thermal specs | Accepts wider voltage variation; suitable where ±1% not required for cost optimization | Select when tighter tolerance is unnecessary and procurement flexibility is prioritized |
| 1N4961US (commercial grade) | Same 13 V/±1%, but only qualified to MIL-PRF-19500/355 (JAN level), not JANTXV | Lacks full JANTXV screening for extended temperature and radiation performance | Use only in non-mission-critical ground systems where full military screening is not mandated |
Compared with JANTXV1N4961CUS/TR, the JANTXV1N4961DUS/TR offers relaxed tolerance at identical reliability, while the 1N4961US reduces cost but sacrifices JANTXV-level temperature range and radiation assurance - selection depends on whether ±1% regulation stability and full Class H operation are mandatory.

FAQ
What is the Zener voltage tolerance of JANTXV1N4961CUS/TR?
JANTXV1N4961CUS/TR has a nominal Zener voltage of 13 V with ±1% tolerance, denoted by the "C" suffix in the part number. This tolerance is guaranteed over the full operating temperature range of –65 °C to +175 °C and applies under specified test conditions per MIL-PRF-19500/356. The tighter tolerance supports precision regulation in feedback paths where output accuracy is critical.
Is JANTXV1N4961CUS/TR qualified to MIL-PRF-19500/356?
Yes, JANTXV1N4961CUS/TR is fully qualified to MIL-PRF-19500/356 as a JANTXV-grade device. This includes screening for extended temperature operation (–65 °C to +175 °C), mechanical shock, vibration, and hermeticity. The qualification confirms suitability for high-reliability military and space applications where component failure is unacceptable.
What is the maximum power dissipation for JANTXV1N4961CUS/TR?
JANTXV1N4961CUS/TR is rated for 5 W power dissipation at an end-cap temperature (TEC) of 140 °C. Above that temperature, power must be linearly derated to zero at +175 °C. This rating assumes proper PCB thermal design using the D-5B package's copper end caps and recommended pad layout per the official Microsemi SD44A datasheet.
Does JANTXV1N4961CUS/TR have radiation hardness?
Yes, JANTXV1N4961CUS/TR is inherently radiation-hardened per Microsemi MicroNote 050, exhibiting tolerance to total ionizing dose (TID) without requiring external shielding or derating. This property stems from its voidless hermetic glass construction and internal metallurgical bonding, making it suitable for LEO and GEO spacecraft applications.
What is the dynamic impedance of JANTXV1N4961CUS/TR at rated test current?
JANTXV1N4961CUS/TR has a maximum dynamic impedance (ZZ) of 3.0 Ω at its specified Zener test current (IZT) of 100 mA. This low impedance value ensures minimal output voltage variation under changing load conditions, supporting stable regulation in shunt-based reference and protection circuits.
