Product details
Overview
JANTXV1N4619C-1/TR from Microsemi is a 3.0 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435, with ±2% voltage tolerance, 1600 Ω dynamic impedance at 250 mA test current, and 0.4 µA max reverse leakage at 2.4 V. It delivers stable voltage regulation in high-reliability analog reference and power supply feedback circuits.
For engineers reviewing the JANTXV1N4619C-1/TR datasheet, JANTXV1N4619C-1/TR pinout, JANTXV1N4619C-1/TR application, or JANTXV1N4619C-1/TR equivalent, key selection criteria include its MIL-qualified reliability grade, low-noise performance (1 µV/√Hz), tight 2% Zener tolerance, and thermal stability across –65 °C to +175 °C junction temperature range.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures mechanical robustness and long-term parameter stability under thermal cycling and radiation exposure.
It exhibits a negative temperature coefficient of –0.075 %/°C and maintains regulation over wide current ranges (IZK near knee to IZM = 87 mA), with noise density dropping to 1 µV/√Hz below 6.8 V - confirmed for JANTXV1N4619C-1/TR at its 3.0 V nominal Zener voltage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4619US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical mounting | Select when board space is constrained and automated SMT placement is available |
| JANTXV1N4619D-1/TR | Identical construction and package, but ±1% Zener tolerance instead of ±2% | Higher cost and longer lead time; justified only where tighter regulation accuracy is required in closed-loop feedback | Select only if system-level error budget demands <±15 mV absolute reference deviation |
Compared with JANTXV1N4619C-1/TR, the US-1 variant trades axial-leaded flexibility for SMT compatibility, while the D-1 variant improves voltage accuracy at the expense of cost and availability - both retain identical thermal, noise, and radiation performance.

FAQ
What is the Zener voltage tolerance for JANTXV1N4619C-1/TR?
JANTXV1N4619C-1/TR has a nominal Zener voltage of 3.0 V with a ±2% tolerance, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified operating temperature range of –65 °C to +175 °C.
Is JANTXV1N4619C-1/TR RoHS compliant?
No, JANTXV1N4619C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade versions (e.g., 1N4619C-1e3); JANTXV-level parts like JANTXV1N4619C-1/TR retain legacy tin-lead plating to meet MIL-PRF-19500/435 requirements and ensure solder joint reliability under thermal cycling.
What is the maximum Zener current IZM for JANTXV1N4619C-1/TR?
The maximum Zener current IZM for JANTXV1N4619C-1/TR is 87.0 mA, derived from its 500 mW power rating and 3.0 V nominal Zener voltage (P = V × I). This value is valid at 25 °C lead temperature and decreases linearly with rising temperature per the derating curve in Figure 2 of the datasheet.
Does JANTXV1N4619C-1/TR have radiation hardness certification?
Yes, JANTXV1N4619C-1/TR is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction and JANTXV qualification per MIL-PRF-19500/435 provide proven total ionizing dose (TID) tolerance and single-event effect (SEE) resilience for space and nuclear applications.
What does the "TR" suffix mean in JANTXV1N4619C-1/TR?
"TR" indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. JANTXV1N4619C-1/TR is supplied in reels with standardized orientation and spacing; this suffix does not affect electrical or reliability specifications - it is purely a packaging option.
