For engineers reviewing the JANTX1N4128D-1/TR datasheet, JANTX1N4128D-1/TR pinout, JANTX1N4128D-1/TR application, or JANTX1N4128D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (≤1 µV/√Hz), dynamic impedance (400 Ω at 250 mA), temperature coefficient (+0.100 %/°C), and MIL-qualified thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures stable Zener voltage under thermal cycling and radiation exposure, supporting operation across –65 °C to +175 °C junction temperature range.
It delivers 60 V regulation at 250 mA test current with 400 Ω dynamic impedance and ≤0.01 µA reverse leakage at 45.6 V, meeting MIL-PRF-19500/435 requirements for JANTX-level reliability including hermetic glass sealing and tin-lead plating per MIL-STD-750 method 2026.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4128US-1 | Same 60 V, 1% Zener voltage but in surface-mount DO-213AA package; no axial leads. | Used where automated SMT assembly and board space reduction are prioritized over through-hole serviceability. | Select when PCB layout requires SMT footprint and thermal profile allows reflow-compatible glass package. |
| JANTXV1N4128D-1 | Identical electrical specs but qualified to higher JANTXV reliability level with additional screening (e.g., burn-in, life test). | Required for mission-critical subsystems where failure probability must be <1 FIT and lot traceability includes full environmental stress screening. | Select when program specification mandates JANTXV-level screening beyond standard JANTX requirements. |
Compared with JANTX1N4128D-1/TR, the 1N4128US-1 offers identical regulation performance in a compact SMT form factor, while JANTXV1N4128D-1 adds enhanced screening for ultra-high-reliability deployments-neither is pin-compatible due to differing packages or screening levels.

FAQ
What is the Zener voltage tolerance of JANTX1N4128D-1/TR?
JANTX1N4128D-1/TR has a nominal Zener voltage of 60.0 V with ±1% tolerance, as indicated by the "D" suffix in its part number per Microsemi's nomenclature. This tight tolerance is verified at 250 mA test current and enables high-accuracy regulation without external trimming in critical reference circuits.
Is JANTX1N4128D-1/TR RoHS compliant?
No, JANTX1N4128D-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts-not for JAN, JANTX, JANTXV, or JANS qualified devices like JANTX1N4128D-1/TR, which retain tin-lead plating for solderability and reliability per MIL-STD-750.
What is the maximum reverse leakage current for JANTX1N4128D-1/TR?
The maximum reverse leakage current (IR) for JANTX1N4128D-1/TR is 0.01 µA at 45.6 V, as specified in the Electrical Characteristics table. This ultra-low leakage supports low-power, battery-operated systems where standby current must remain below nanoampere thresholds.
How does the temperature coefficient affect JANTX1N4128D-1/TR performance?
JANTX1N4128D-1/TR has a temperature coefficient of +0.100 %/°C, meaning its Zener voltage increases by 60 mV per °C rise in junction temperature. This predictable positive drift allows designers to compensate for thermal effects in closed-loop systems or select complementary components for zero-TC reference networks.
What packaging format does JANTX1N4128D-1/TR use?
JANTX1N4128D-1/TR uses the DO-35 (DO-204AH) axial-leaded glass package with hermetic sealing, tin-lead plated leads, and cathode identified by a black band. The "TR" suffix indicates tape-and-reel packaging per EIA-296 for automated assembly, containing standard reel quantities per factory specification.
