Product details
Overview
JANTXV1N4627C-1/TR from Microsemi is a 500 mW, 6.2 V Zener voltage regulator diode in DO-35 glass axial-leaded package, qualified to JANTXV level per MIL-PRF-19500/435, with ±2% voltage tolerance, 1200 Ω dynamic impedance at 250 mA test current, and 5 µV/√Hz noise density - used for precision voltage reference and regulation in military-grade power supply monitoring circuits.
For engineers reviewing the JANTXV1N4627C-1/TR datasheet, JANTXV1N4627C-1/TR pinout, JANTXV1N4627C-1/TR application, or JANTXV1N4627C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (5 µV/√Hz), JANTXV reliability qualification, thermal resistance (250 °C/W junction-to-lead), and DO-35 mechanical compatibility with through-hole PCB layouts.
Technical Context
This device operates as a reverse-biased Zener regulator with metallurgically bonded construction for enhanced reliability and radiation hardness. Its 6.2 V nominal Zener voltage exhibits a temperature coefficient of –0.010 to +0.050 %/°C, enabling stable regulation across –65 to +175 °C junction temperature range.
The diode delivers 61 mA maximum Zener current (IZM) at rated 500 mW dissipation, with dynamic impedance measured at 1200 Ω under 250 mA test current (IZT). Reverse leakage is limited to ≤5 µA at VR = 5.0 V, and forward voltage is 1.1 V at 200 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±2% at 250 mA - ensures tight regulation tolerance for reference-critical analog subsystems. |
| Power Dissipation | 500 mW at TC = 25 °C - supports stable operation in compact, convection-cooled military enclosures. |
| Dynamic Impedance (ZZT) | 1200 Ω at IZT = 250 mA - defines output impedance under regulation, critical for ripple rejection in feedback loops. |

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/TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Requires rework of PCB layout for SMT assembly; eliminates through-hole mounting. | Select when board space is constrained and automated placement is required. |

FAQ
What is the Zener voltage tolerance of JANTXV1N4627C-1/TR?
JANTXV1N4627C-1/TR has a nominal Zener voltage of 6.2 V with a tolerance of ±2%, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified operating temperature range of –65 to +175 °C.
Is JANTXV1N4627C-1/TR RoHS compliant?
No, JANTXV1N4627C-1/TR is not RoHS compliant. Per the Microsemi datasheet T4-LDS-0245-2, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts, not for JAN, JANTX, JANTXV, or JANS qualified devices like JANTXV1N4627C-1/TR.
What does the "TR" suffix mean in JANTXV1N4627C-1/TR?
The "TR" suffix in JANTXV1N4627C-1/TR indicates tape-and-reel packaging per EIA-296 standard, intended for automated pick-and-place assembly. It does not affect electrical or reliability specifications - the underlying device remains identical to the bulk version JANTXV1N4627C-1.
What is the maximum Zener current rating for JANTXV1N4627C-1/TR?
JANTXV1N4627C-1/TR has a maximum Zener current (IZM) of 61 mA, derived from its 500 mW power rating and 6.2 V Zener voltage (P = V × I). This value assumes operation at 25 °C lead temperature; derating begins linearly at 50 °C and reaches zero at 175 °C per Figure 2 in the datasheet.
How is polarity marked on JANTXV1N4627C-1/TR?
JANTXV1N4627C-1/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking follows JEDEC DO-35 standards and is visible on the glass body near one lead.
