Product details
Overview
JANTXV1N4615C-1 from Microsemi is a 2.0 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JANTXV1N4615C-1 datasheet, JANTXV1N4615C-1 pinout, JANTXV1N4615C-1 application, or JANTXV1N4615C-1 equivalent, key selection criteria include Zener voltage tolerance (2%), noise density (1 µV/√Hz), thermal resistance (250 °C/W), and military-grade reliability qualification.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 2.0 V at 250 mA test current, exhibiting a temperature coefficient of –0.075 %/°C and dynamic impedance of 1250 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation in the reverse-biased breakdown region, JANTXV1N4615C-1 maintains regulation across wide current ranges (IZK to IZM) with low leakage (IR ≤ 2.5 µA at VR = 1.0 V) and minimal capacitance-typical values fall below 10 pF per Figure 3 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.0 V ±2% at 250 mA - defines precise reference point for low-voltage biasing and calibration circuits. |
| Power Dissipation | 500 mW at TC = 25 °C - supports stable regulation in compact through-hole layouts with defined derating above 50 °C. |
| Zener Impedance ZZT | 1250 Ω at IZT = 250 mA - indicates moderate AC impedance affecting regulation stability under varying load currents. |
| Noise Density ND | 1 µV/√Hz at IZT - enables use in low-noise analog references where voltage ripple must be minimized. |
| Reverse Leakage IR | ≤2.5 µA at VR = 1.0 V - ensures minimal parasitic current draw in standby or high-impedance sensing nodes. |
| Temp Coefficient αVZ | –0.075 %/°C - provides predictable, negative drift over temperature for compensated reference designs. |
| Package | DO-35 (DO-204AH) - axial-leaded hermetic glass package rated for –65 to +175 °C operation. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded hermetically sealed glass package with cathode indicated by band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to circuit common; establishes return path for Zener current during regulation. |
| Cathode (banded end) | Regulated output node | Supplies stable 2.0 V reference when reverse-biased; polarity must be observed to avoid forward conduction. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTXV qualification | Validated for high-reliability aerospace and defense systems requiring extended temperature range and radiation hardness. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4615US-1 | Same 2.0 V/2% spec but in DO-213AA surface-mount package; no JANTXV qualification. | Lacks military reliability screening; suitable only for commercial industrial PCBs with space constraints. | Select when board area is critical and MIL-spec is not required. |
| JANTXV1N4615D-1 | Identical electrical specs but 1% Zener tolerance instead of 2%; same JANTXV qualification and DO-35 package. | Higher precision needed for metrology or laser diode bias where ±10 mV error is unacceptable. | Select when tighter voltage accuracy justifies higher cost and longer lead times. |
Compared with JANTXV1N4615C-1, the 1N4615US-1 trades military reliability for SMT compatibility, while JANTXV1N4615D-1 delivers improved voltage accuracy within the same qualified package-enabling trade-offs between precision, form factor, and qualification level.

FAQ
What is the Zener voltage tolerance of JANTXV1N4615C-1?
JANTXV1N4615C-1 has a Zener voltage tolerance of ±2%, meaning its regulated voltage falls within 1.96 V to 2.04 V at 250 mA test current and 25 °C. This tolerance is marked by the "C" suffix in the part number per Microsemi's nomenclature guide and is verified per MIL-PRF-19500/435 testing protocols.
Is JANTXV1N4615C-1 suitable for surface-mount assembly?
No, JANTXV1N4615C-1 uses the axial-leaded DO-35 (DO-204AH) package and is not compatible with standard SMT reflow processes. For surface-mount equivalents, consider the 1N4615US-1 in DO-213AA package-but note it lacks JANTXV qualification and military screening.
What is the maximum reverse leakage current for JANTXV1N4615C-1?
JANTXV1N4615C-1 specifies a maximum reverse leakage current (IR) of 2.5 µA at VR = 1.0 V, measured at 25 °C. This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1 and reflects tight control over junction quality in JANTXV-qualified units.
Does JANTXV1N4615C-1 require heatsinking in normal operation?
JANTXV1N4615C-1 does not require external heatsinking at 500 mW dissipation if lead length is maintained at 10 mm (3/8 inch) from the body, achieving RθJL = 250 °C/W. Derating begins linearly at 50 °C case temperature, reaching zero power at 175 °C per Figure 2 in the datasheet.
How is polarity identified on JANTXV1N4615C-1?
JANTXV1N4615C-1 uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the anode to achieve Zener regulation. Forward voltage is 1.1 V at 200 mA, confirming standard silicon PN junction behavior per Maximum Ratings table.
