Product details
Overview
JAN1N3614/TR from Microsemi is a military-qualified, voidless-hermetically-sealed standard recovery glass rectifier diode rated for 800 V working peak reverse voltage, 1.0 A average forward current at 100°C, and 30 A surge current (8.3 ms), used in high-reliability power conversion stages of avionics power supplies and radiation-hardened DC/DC converters.
For engineers reviewing the JAN1N3614/TR datasheet, JAN1N3614/TR pinout, JAN1N3614/TR application, or JAN1N3614/TR equivalent, key selection criteria include its MIL-PRF-19500/228 qualification, Category I metallurgical bond, -65°C to +175°C operating temperature range, and controlled avalanche capability under transient overvoltage conditions.
Technical Context
This axial-lead, hard-glass rectifier uses tungsten slugs and Sn/Pb-plated copper leads to achieve low thermal resistance (38°C/W) and robust mechanical integrity. Its standard recovery time supports line-frequency rectification without excessive switching loss or EMI concerns.
The device operates with a maximum forward voltage of 1.1 V at 1 A (pulsed), leakage current ≤300 μA at 800 V, and minimum breakdown voltage of 920 V - all specified at 30°C case temperature per MIL-PRF-19500/228 test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 800 V - Maximum continuous reverse voltage the diode sustains across AC line inputs without breakdown. |
| VBR @ 100 μA | 920 V min - Ensures margin against transient overvoltage events in regulated power supplies. |
| IO @ 100°C | 1.0 A - Sustained DC output current capability in convection-cooled avionics enclosures. |
| VF @ 1 A (pulsed) | 1.1 V max - Limits conduction loss and self-heating during steady-state operation. |
| IR @ VRWM | ≤300 μA - Low leakage preserves efficiency in high-impedance bias networks and sensing circuits. |
| IFSM (8.3 ms) | 30 A - Withstands inrush currents from large input capacitors in MIL-spec power modules. |
| Junction Temp Range | -65°C to +175°C - Enables deployment in extreme environments including space-grade thermal cycling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N3613 | 600 V VRWM, 720 V VBR - 200 V lower reverse rating than JAN1N3614/TR. | Used where system peak voltage is limited to ≤650 V; not suitable for 800 V line-fed designs. | Select when derating margin allows lower VRWM to reduce cost or improve VF consistency. |
| 1N5614US | Surface-mount MELF package; same electrical specs but no hermetic seal; RoHS-compliant finish. | Preferred for automated SMT assembly; unsuitable for vacuum or high-humidity sealed enclosures. | Choose for commercial/mixed-use systems requiring volume production and reflow compatibility. |
Compared with JAN1N3614/TR, JAN1N3613 offers lower voltage headroom but identical thermal and surge performance, while 1N5614US trades hermeticity and radiation tolerance for SMT manufacturability - making JAN1N3614/TR irreplaceable in mission-critical aerospace deployments.

FAQ
What is the maximum junction temperature rating for JAN1N3614/TR?
JAN1N3614/TR has a junction and storage temperature range of -65°C to +175°C, verified per MIL-PRF-19500/228 screening. This enables operation in extreme thermal environments such as engine-mounted electronics or space-based power systems where ambient temperatures exceed 125°C. The 175°C upper limit reflects the device's tungsten-slug construction and voidless glass seal integrity.
Is JAN1N3614/TR suitable for use in radiation-intensive environments like low-Earth orbit?
Yes, JAN1N3614/TR is inherently radiation-hardened as documented in Microsemi MicroNote 050, supporting total ionizing dose (TID) tolerance up to 100 krad(Si). Its hermetic glass package and Category I metallurgical bond prevent parametric shift under proton and gamma exposure - making JAN1N3614/TR appropriate for satellite power subsystems and nuclear instrumentation where long-term reliability under radiation is mandatory.
Does JAN1N3614/TR have a controlled avalanche rating, and how is it applied in circuit design?
JAN1N3614/TR features controlled avalanche capability with defined peak reverse power limits, allowing safe energy absorption during inductive switching events. In practice, this permits use as a catch diode in relay drivers or snubberless flyback converters without external clamping - a key advantage over non-avalanche-rated rectifiers. The specification is validated per MIL-PRF-19500/228 test method 3014.
What packaging and marking details apply to JAN1N3614/TR?
JAN1N3614/TR uses an axial-lead "A" package with voidless hermetically sealed hard glass body, tungsten slugs, and Sn/Pb-plated copper leads. It is marked with a cathode band and body paint indicating the part number. Lead length ranges from 0.600 to 1.500 inches, and the device weighs approximately 500 mg. Dimensions conform to T4-LDS-0190 Rev. 1.
How does JAN1N3614/TR differ from commercial-grade 1N3614 variants?
JAN1N3614/TR is the military-qualified version per MIL-PRF-19500/228, featuring full lot traceability, extended temperature screening (-65°C to +175°C), burn-in, and mechanical vibration testing. Commercial 1N3614 lacks these screens, has narrower temp range (-65°C to +125°C), and no radiation hardness validation - making JAN1N3614/TR the only variant approved for flight-critical avionics and nuclear applications.
