FAQ
What is the Zener voltage tolerance of JANTXV1N4119D-1/TR?
JANTXV1N4119D-1/TR has a nominal Zener voltage of 28.0 V with ±1% tolerance, denoted by the "D" suffix in its part number per MIL-PRF-19500/435 nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified temperature range when used within derated power limits.
Is JANTXV1N4119D-1/TR RoHS compliant?
No, JANTXV1N4119D-1/TR is not RoHS compliant. Per the manufacturer's documentation, RoHS-compliant versions (suffix "e3") are available only for commercial-grade variants-not for JAN, JANTX, JANTXV, or JANS reliability levels. The JANTXV1N4119D-1/TR uses traditional tin-lead plating per MIL-STD-750.
What does the "TR" suffix indicate in JANTXV1N4119D-1/TR?
The "TR" suffix in JANTXV1N4119D-1/TR indicates tape-and-reel packaging per EIA-296 standard, intended for automated pick-and-place assembly. It does not affect electrical specifications or reliability level-JANTXV1N4119D-1/TR retains full JANTXV qualification and DO-35 mechanical form factor.
How is polarity marked on JANTXV1N4119D-1/TR?
JANTXV1N4119D-1/TR uses a cathode band marking on the glass body to indicate polarity. For Zener regulation, the banded end must be biased positive relative to the anode-this is the standard reverse-bias configuration required to achieve 28.0 V breakdown conduction.
What is the maximum Zener current IZM for JANTXV1N4119D-1/TR?
The maximum Zener current IZM for JANTXV1N4119D-1/TR is 40 mA, derived from its 500 mW power rating and 28.0 V nominal Zener voltage (IZM = PM(AV)/VZ ≈ 17.9 mA), with margin added per Microsemi's published electrical characteristics table showing 40 mA as the rated maximum regulator current at 25 °C.
