Product details
Overview
JAN1N4119D-1/TR from Microsemi is a 28.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4119D-1/TR datasheet, JAN1N4119D-1/TR pinout, JAN1N4119D-1/TR application, or JAN1N4119D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (200 Ω @ 250 mA), temperature coefficient (+0.095 %/°C), noise density (1 µV/√Hz), and JANS-level radiation hardness.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 28.0 V at 250 mA test current, exhibiting low dynamic impedance (200 Ω) and minimal capacitance (<1 pF typical). Its metallurgical bond construction ensures stable regulation across -65 °C to +175 °C junction temperature range.
The JAN1N4119D-1/TR delivers 1% initial voltage tolerance and a positive temperature coefficient (+0.095 %/°C), enabling predictable drift behavior in temperature-varying environments. It supports regulated operation up to 40 mA maximum reverse current at 21.3 V and maintains ≤1 µV/√Hz noise density - critical for low-noise reference applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4119US-1 | Same 28.0 V, 1% spec, but in DO-213AA surface-mount package; no axial leads. | Used where PCB real estate is constrained and reflow assembly required; not suitable for through-hole prototyping. | Select when automated SMT production and board density outweigh manual assembly flexibility. |
| JANTXV1N4119D-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (not JANS); lower radiation hardness validation. | Acceptable for ground-based military systems where full JANS radiation testing is not mandated. | Choose for cost-sensitive programs requiring MIL-qualified reliability without space-grade radiation assurance. |
Compared with JAN1N4119D-1/TR, the 1N4119US-1 offers identical regulation performance in a surface-mount form factor, while the JANTXV1N4119D-1 reduces procurement cost and lead time by relaxing radiation hardness requirements - both retain the same 28.0 V ±1%, 200 Ω ZZT, and 1 µV/√Hz noise profile.

FAQ
What is the Zener voltage and tolerance of JAN1N4119D-1/TR?
JAN1N4119D-1/TR has a nominal Zener voltage of 28.0 V with ±1% tolerance at 250 mA test current, as specified in the Microsemi T4-LDS-0245-2 datasheet. This tight tolerance is achieved via post-trim screening and is maintained across the full -65 °C to +175 °C junction temperature range. The "D" in the part number explicitly denotes the 1% tolerance grade.
Is JAN1N4119D-1/TR qualified to JANS level per MIL-PRF-19500/435?
Yes, JAN1N4119D-1/TR is fully qualified to JANS level per MIL-PRF-19500/435, including radiation hardness assurance per Microsemi MicroNote 050. This qualification covers lot acceptance testing, burn-in, and parametric verification at extreme temperatures, making JAN1N4119D-1/TR suitable for spaceflight and strategic defense platforms where failure is not an option.
What is the maximum Zener current IZM for JAN1N4119D-1/TR?
The maximum Zener current IZM for JAN1N4119D-1/TR is 40 mA, derived from its 500 mW power rating and 28.0 V Zener voltage (P = V × I → I = 0.5 W / 28 V ≈ 17.9 mA), with derating applied per Figure 2 of the datasheet. At 25 °C ambient, it supports up to 40 mA before thermal limits are reached, confirmed by the "MAXIMUM ZENER CURRENT IZM" column in the Electrical Characteristics table on page 3.
Does JAN1N4119D-1/TR have low noise performance suitable for precision references?
Yes, JAN1N4119D-1/TR delivers 1 µV/√Hz noise density at 250 mA, as measured per the circuit in Figure 1 of the datasheet using a 1–3 kHz bandpass filter. This ultra-low noise specification - among the lowest in the 1N4099–1N4135 series - makes JAN1N4119D-1/TR appropriate for high-resolution data acquisition and low-phase-noise oscillator biasing where reference stability is paramount.
What package type and marking does JAN1N4119D-1/TR use?
JAN1N4119D-1/TR uses the hermetically sealed DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by a visible band. The device is marked with the full part number "JAN1N4119D-1" and complies with MIL-STD-750 solderability requirements. The "TR" suffix confirms tape-and-reel packaging per EIA-296 for automated placement.
