Product details
Overview
JANTXV1N3614 from Microsemi is a military-grade standard-recovery axial-lead glass rectifier diode rated for 800 V working peak reverse voltage, 1.0 A average forward current at 100°C, and 30 A non-repetitive surge current; it features voidless hermetic glass packaging with Category I metallurgical bond and is used in high-reliability power conversion circuits such as MIL-STD-461-compliant avionics power supplies.
For engineers reviewing the JANTXV1N3614 datasheet, JANTXV1N3614 pinout, JANTXV1N3614 application, or JANTXV1N3614 equivalent, key selection considerations include its 920 V minimum breakdown voltage, 1.1 V max forward voltage at 1 A pulsed, 300 µA max reverse leakage at 800 V, -65°C to +175°C operating temperature range, and radiation-hardened construction per MicroNote 050.
Technical Context
This diode operates as a unidirectional current-conducting device in AC-to-DC conversion stages, relying on standard recovery characteristics (trr not specified but typical for 1N36xx series is >500 ns) and controlled avalanche capability under transient overvoltage conditions. Its internal tungsten slug construction enables low thermal resistance (38°C/W junction-to-lead) and robust surge handling.
The JANTXV1N3614 is qualified to MIL-PRF-19500/228 Level JANTXV and employs a hermetically sealed voidless glass case with Sn/Pb-plated copper axial leads and cathode band polarity marking. It is not intended for high-frequency switching but excels in ruggedized linear and transformer-based power supplies where reliability outweighs speed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage (VRWM) | 800 V - Maximum continuous reverse voltage the diode sustains without breakdown in operation. |
| Minimum Breakdown Voltage (VBR) | 920 V @ 100 µA - Ensures margin against transient overvoltage events before avalanche onset. |
| Average Forward Current (IO) | 1.0 A @ TA = 100°C - Sustained DC output capability in convection-cooled rectifier designs. |
| Forward Voltage Drop (VF) | 1.1 V @ 1 A pulsed - Directly impacts conduction loss and thermal rise in power stage efficiency calculations. |
| Reverse Leakage Current (IR) | 300 µA @ VRWM = 800 V - Low leakage preserves efficiency in high-impedance bias networks and standby circuits. |
| Non-Repetitive Surge Current (IFSM) | 30 A @ 8.3 ms half-sine - Withstands inrush currents during cold-start of transformer-coupled supplies. |
| Junction Temperature Range | -65°C to +175°C - Enables deployment in extended-environment aerospace, downhole, and defense electronics. |

FAQ
What is the maximum working peak reverse voltage for JANTXV1N3614?
The JANTXV1N3614 has a maximum working peak reverse voltage (VRWM) of 800 V, as defined in MIL-PRF-19500/228 and confirmed in the T4-LDS-0190 datasheet. This rating applies across the full operating temperature range of -65°C to +175°C and represents the highest continuous reverse voltage the device can sustain without breakdown. Exceeding this value risks premature avalanche or parametric shift, especially under thermal stress.
Does JANTXV1N3614 have radiation-hardened characteristics?
Yes, the JANTXV1N3614 exhibits inherent radiation hardness due to its hermetic glass package, silicon die process, and metallurgical construction, as documented in Microsemi MicroNote 050. It is not individually tested to MIL-STD-883 Method 1019, but its design and qualification per MIL-PRF-19500/228 provide proven resilience to total ionizing dose (TID) in space and nuclear instrumentation applications.
What is the forward voltage drop of JANTXV1N3614 at rated current?
The JANTXV1N3614 has a maximum forward voltage drop (VF) of 1.1 V at 1 A pulsed current and 25°C case temperature, per the Electrical Characteristics table on page 3 of T4-LDS-0190. At elevated temperatures or DC conditions, VF decreases slightly due to negative temperature coefficient, but design margins should retain the 1.1 V value for worst-case power loss and thermal analysis of the JANTXV1N3614.
Can JANTXV1N3614 be used in surface-mount designs?
No, the JANTXV1N3614 is an axial-lead through-hole device in a hermetic glass "A" package and is not compatible with surface-mount assembly processes. For surface-mount equivalents, Microsemi offers the 1N5614US–1N5622US MELF series; however, those are commercial-grade and lack JANTXV qualification, so they are not drop-in replacements for JANTXV1N3614 in military or space applications.
What is the thermal resistance of JANTXV1N3614?
The JANTXV1N3614 has a thermal resistance of 38°C/W from junction to lead, measured at 3/8 inch (10 mm) lead length from the body, as specified in the Maximum Ratings section. This value assumes standard lead mounting and convection cooling; actual thermal performance depends on PCB copper area, lead bending, and ambient airflow. Derating curves in the datasheet must be applied for operation above 100°C ambient.
