Product details
Overview
JANTX1N4627C-1/TR from Microsemi is a 6.2 V, ±2% tolerance, 500 mW axial-leaded Zener diode in DO-35 (DO-204AH) glass package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning and precision reference circuits.
For engineers reviewing the JANTX1N4627C-1/TR datasheet, JANTX1N4627C-1/TR pinout, JANTX1N4627C-1/TR application, or JANTX1N4627C-1/TR equivalent, key selection factors include its 6.2 V nominal Zener voltage at 250 mA test current, 1200 Ω dynamic impedance, 5 µA maximum reverse leakage at 5.0 V, ±2% voltage tolerance, and radiation-hardened metallurgical bond construction.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its internal metallurgical bond ensures stable junction characteristics across temperature extremes from –65 °C to +175 °C and supports operation under high-reliability military environmental stress profiles.
The JANTX1N4627C-1/TR exhibits a temperature coefficient of –0.010 to +0.050 %/°C and delivers 1 µV/√Hz noise density at low voltages-critical for analog reference stability in avionics sensor signal chains and regulated bias supplies where low-noise DC references are required.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4627US-1 | Same 6.2 V, ±2%, DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy board repair | Select when automated assembly and space-constrained layouts are prioritized over manual serviceability |
| JAN1N4627C-1 | Identical electrical specs but qualified only to JAN level (lower screening vs. JANTX) | Limited to non-critical subsystems where full JANTX burn-in and lot traceability are not mandated | Choose for cost-sensitive designs meeting baseline MIL-PRF-19500 requirements without extended reliability testing |
Compared with JANTX1N4627C-1/TR, the 1N4627US-1 offers identical regulation performance in a smaller footprint but eliminates field-serviceable axial mounting, while JAN1N4627C-1 reduces procurement cost and lead time at the expense of JANTX-level screening rigor and lot traceability.

FAQ
What is the Zener voltage and test current for JANTX1N4627C-1/TR?
JANTX1N4627C-1/TR has a nominal Zener voltage of 6.2 V measured at a test current (IZT) of 250 mA. This value is guaranteed within ±2% tolerance and represents the stable regulation point under specified thermal conditions per MIL-PRF-19500/435.
Is JANTX1N4627C-1/TR RoHS compliant?
No, JANTX1N4627C-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions. JANTX1N4627C-1/TR uses traditional tin-lead plating and meets MIL-PRF-19500/435 requirements for high-reliability applications where leaded finishes are permitted.
What does the "C" in JANTX1N4627C-1/TR signify?
The "C" in JANTX1N4627C-1/TR indicates a ±2% Zener voltage tolerance, per Microsemi's part nomenclature. Standard tolerance is ±5% (blank), "D" denotes ±1%, and "C" is the designated code for the tighter ±2% bin used in precision regulation applications.
What is the maximum power dissipation of JANTX1N4627C-1/TR at 25 °C?
JANTX1N4627C-1/TR has a rated average power dissipation of 500 mW at 25 °C case temperature. Power must be linearly derated starting at 50 °C ambient, reaching zero at 175 °C, per the thermal derating curve in the official datasheet.
How is polarity marked on JANTX1N4627C-1/TR?
JANTX1N4627C-1/TR uses a single black cathode band on the glass body to indicate polarity. For proper Zener regulation, the banded (cathode) end must be held positive relative to the anode end when reverse-biased in the circuit.
