Product details

Overview

JANTXV1N4627D-1/TR from Microsemi is a 1% tolerance, 6.2 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.

For engineers reviewing the JANTXV1N4627D-1/TR datasheet, JANTXV1N4627D-1/TR pinout, JANTXV1N4627D-1/TR application, or JANTXV1N4627D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (5 µV/√Hz), dynamic impedance (1200 Ω), temperature coefficient (–0.010 to +0.050 %/°C), and JANTXV-level qualification for extended temperature operation (–65 °C to +175 °C).

Technical Context

This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 6.2 V at 250 mA test current, exhibiting low noise density (5 µV/√Hz) and stable regulation across –65 °C to +175 °C junction temperature range. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and vibration stress.

The JANTXV1N4627D-1/TR features a cathode band marking for polarity identification and is designed for axial-leaded mounting on FR4 PCBs with 4 mm² copper pads. It delivers 500 mW average power dissipation at 25 °C, derating linearly to zero at 175 °C ambient per MIL-PRF-19500/435 requirements.

Zener Voltage (V_Z)	6.2 V ±1% at 250 mA - enables precise reference generation in analog circuits requiring tight voltage stability.
Power Dissipation (P_M(AV))	500 mW at 25 °C - supports continuous regulation in compact, convection-cooled designs without forced airflow.
Dynamic Impedance (Z_ZT)	1200 Ω max at 250 mA - limits output voltage variation under load transients in feedback references.
Noise Density (N_D)	5 µV/√Hz at 250 mA - critical for low-noise analog signal chains including precision ADC references and sensor excitation.
Temperature Coefficient (α_VZ)	–0.010 to +0.050 %/°C - ensures minimal drift over wide operating ranges in avionics and satellite power systems.
Reverse Leakage (I_R)	5.0 µA max at 5.0 V - guarantees low standby current in battery-backed or low-power hold-up circuits.
Junction Temperature Range	–65 °C to +175 °C - validated for deployment in extreme-environment military and space-grade electronics.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4627US-1TR	Same 6.2 V, 1% tolerance, but in DO-213AA surface-mount package; no axial leads.	Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention.	Select when board space is constrained and automated assembly is used; verify thermal pad layout matches R_θJL = 250 °C/W requirement.
JANTXV1N4627-1/TR	Same 6.2 V rating but ±5% tolerance; higher IR (5.0 µA vs. 5.0 µA) and identical ZZT (1200 Ω).	Acceptable where calibration compensates for initial tolerance; less suitable for untrimmed precision references.	Choose for cost-sensitive programs where post-calibration is standard; avoid in factory-set "no-trim" designs.

Compared with JANTXV1N4627D-1/TR, the JANTXV1N4627-1/TR offers lower cost but requires system-level tolerance budgeting, while the 1N4627US-1TR enables miniaturization at the expense of mechanical ruggedness and hand-soldering feasibility.

FAQ

What is the Zener voltage tolerance of JANTXV1N4627D-1/TR?

JANTXV1N4627D-1/TR has a Zener voltage tolerance of ±1%, specified per its "D" suffix in the MIL nomenclature. This corresponds to a 6.2 V nominal rating with actual V_Z ranging from 6.138 V to 6.262 V at I_ZT = 250 mA and T_C = 25 °C. The tight tolerance eliminates need for external trimming in calibrated reference designs.

Is JANTXV1N4627D-1/TR RoHS compliant?

No, JANTXV1N4627D-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 JANTXV-level qualified devices. The JANTXV1N4627D-1/TR uses tin-lead plating per MIL-STD-750 and retains legacy Pb content for solderability and reliability in high-reliability assemblies.

What is the maximum Zener current (I_ZM) for JANTXV1N4627D-1/TR?

The maximum Zener current I_ZM for JANTXV1N4627D-1/TR is 61.0 mA, derived from its 500 mW power rating and 6.2 V nominal Zener voltage (I_ZM = P_M(AV)/V_Z). This value assumes operation at 25 °C lead temperature; derating applies above 50 °C per MIL-PRF-19500/435 Figure 2.

How does the noise performance of JANTXV1N4627D-1/TR compare to lower-voltage Zeners?

JANTXV1N4627D-1/TR exhibits 5 µV/√Hz noise density at 250 mA, consistent with Microsemi's specification that noise falls rapidly below 6.8 V - e.g., 1N4625-1 (5.1 V) shows 2 µV/√Hz. This makes JANTXV1N4627D-1/TR among the lowest-noise options in the 6 V class, suitable for high-fidelity analog references where broadband noise directly impacts measurement resolution.

What is the thermal resistance from junction to lead (R_θJL) for JANTXV1N4627D-1/TR?

The thermal resistance from junction to lead (R_θJL) for JANTXV1N4627D-1/TR is 250 °C/W, measured with 10 mm (3/8 inch) lead length from the DO-35 package body. This value assumes standard mounting on FR4 with 4 mm² copper pads and is critical for calculating junction temperature rise under sustained 500 mW dissipation in conduction-cooled applications.
