Product details
Overview
JAN1N3611/TR from Microsemi is a military-qualified, voidless-hermetically-sealed standard recovery glass rectifier diode rated for 200 V working peak reverse voltage, 1.0 A average forward current at 100°C, and 30 A non-repetitive surge current; it serves as a robust, radiation-hardened power conversion component in high-reliability DC power supplies and EMI-filtered rectification stages.
For engineers reviewing the JAN1N3611/TR datasheet, JAN1N3611/TR pinout, JAN1N3611/TR application, or JAN1N3611/TR equivalent, key selection factors include its MIL-PRF-19500/228 qualification, -65°C to +175°C operating temperature range, 38°C/W thermal resistance, controlled avalanche capability, and axial-leaded "A" package with cathode band polarity marking.
Technical Context
This diode operates as a unidirectional, standard-recovery (non-fast) rectifier with a typical forward voltage of 1.1 V at 1 A pulsed and maximum reverse leakage of 300 µA at 200 V and 25°C. Its internal Category I metallurgical bond and voidless-glass construction ensure hermetic reliability under thermal cycling and mechanical stress.
Designed for high-reliability environments, JAN1N3611/TR supports linear derating from 1.0 A at 100°C to 0.30 A at 150°C and withstands soldering at 260°C for 10 seconds. It exhibits controlled avalanche behavior with specified peak reverse power capability, enabling use in snubberless or energy-dissipative clamp circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage (VRWM) | 200 V - Maximum continuous reverse voltage the device blocks across full temperature range (-65°C to +175°C). |
| Average Forward Current (IO) | 1.0 A @ TA = 100°C - Sustained DC output current capability in open-frame, free-air conditions with 3/8″ lead length. |
| Forward Voltage (VF) | 1.1 V @ 1 A pulsed - Conduction loss baseline for efficiency estimation in low-frequency rectifier designs. |
| Reverse Leakage (IR) | 300 µA @ VRWM = 200 V, 25°C - Low leakage ensures minimal standby power loss and stable bias in precision hold circuits. |
| Surge Current (IFSM) | 30 A @ 8.3 ms half-sine - Withstands inrush and transient overloads without degradation, critical for input-stage protection. |
| Thermal Resistance (RθJL) | 38°C/W junction-to-lead - Enables direct thermal modeling using lead-mount heatsinking; no PCB copper pour required for basic derating. |
| Operating Temperature | -65°C to +175°C - Fully qualified for extended-range aerospace, downhole, and defense electronics without derating penalties. |
Pinout & Package
Package: Axial-leaded "A" package per T4-LDS-0190; hermetically sealed voidless hard glass case with tungsten slugs; cathode identified by painted band; Sn/Pb-plated copper leads; weight ≈ 500 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive input terminal for forward conduction | Connected to AC source or transformer secondary; must handle full surge current and thermal dissipation during conduction. |
| Cathode | Negative output terminal; marked with band | Delivers rectified DC output; polarity marking prevents reverse installation in high-reliability assemblies. |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic glass seal | Eliminates internal moisture and gas migration, ensuring >20-year shelf life and immunity to humidity-induced parameter drift. |
| Category I metallurgical bond | Provides mechanical integrity under shock/vibration up to 100 g and thermal cycling from -65°C to +175°C without bond fatigue. |
| Controlled avalanche capability | Enables safe operation under transient overvoltage without catastrophic failure-supports simplified snubberless flyback or clamp designs. |
| Radiation hardness | Qualified per MicroNote 050; suitable for low-dose-rate space applications where total ionizing dose (TID) exceeds 100 krad(Si). |
| MIL-PRF-19500/228 qualification | Guarantees screening, testing, and traceability per military standards-including lot acceptance tests, burn-in, and parametric verification. |
Applications
| Avionics Power Supply | Downhole Instrumentation |

Use Scenario: DC power generation from seeker gimbal motor back-EMF during guidance phase. IC Role / Device Role / Timing Role: Catch diode in regenerative braking path, dissipating kinetic energy as heat during rapid deceleration. Use Value: Controlled avalanche behavior allows predictable energy absorption without external snubbers-reducing BOM count and volume. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard-recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N3611 (commercial grade) | No MIL-PRF-19500/228 qualification; lower screening level; same electrical specs and package. | Not approved for flight-critical or mission-essential systems requiring traceable military screening. | Select only for ground-test prototypes or cost-sensitive non-mission hardware where full qualification is unnecessary. |
| JAN1N3612/TR | Higher VRWM (400 V) and VBR (480 V); identical thermal, surge, and temperature ratings. | Used where system-level reverse voltage margin exceeds 200 V-e.g., 28 V systems with 400 V transient clamping requirements. | Choose JAN1N3612/TR when design requires ≥300 V reverse margin but retains same footprint, thermal profile, and reliability class. |
Compared with JAN1N3611/TR, the commercial 1N3611 lacks military screening and traceability, while JAN1N3612/TR offers higher reverse voltage headroom without changing thermal management or layout-making it a direct upgrade path for voltage-margin-limited designs.

FAQ
What does the "JAN" prefix signify for JAN1N3611/TR?
The "JAN" prefix indicates Joint Army-Navy specification compliance and confirms that JAN1N3611/TR is fully qualified to MIL-PRF-19500/228. This includes rigorous screening-such as temperature cycling, steady-state life test, and parametric verification-ensuring performance stability across -65°C to +175°C. JAN1N3611/TR also carries full traceability to wafer lot and assembly batch, a requirement for mission-critical deployments.
Is JAN1N3611/TR compatible with lead-free soldering processes?
JAN1N3611/TR features Sn/Pb-plated copper leads and is rated for 260°C for 10 seconds-matching traditional tin-lead reflow profiles. It is not qualified for Pb-free soldering (e.g., SAC305 at 260°C peak), as the Sn/Pb finish may degrade or dewet. For RoHS-compliant designs, consult Microchip's qualified alternatives or verify compatibility via joint qualification testing before implementation.
Does JAN1N3611/TR support avalanche energy dissipation in clamp circuits?
Yes-JAN1N3611/TR is characterized for controlled avalanche operation with defined peak reverse power capability, as documented in Microsemi MicroNote 050. This enables reliable use in snubberless flyback transformers or inductive load catch circuits without external Zener clamps, provided pulse duration and repetition rate remain within datasheet limits for non-repetitive surge.
What is the thermal resistance value for JAN1N3611/TR, and how is it measured?
JAN1N3611/TR has a junction-to-lead thermal resistance (RθJL) of 38°C/W, measured with 3/8 inch (10 mm) lead length from the diode body. This value assumes axial lead mounting to a heatsink or PCB copper plane; it does not include PCB conduction or ambient-to-lead resistance. Designers should use this figure for junction temperature estimation when heatsinking directly to the leads-not the case.
Can JAN1N3611/TR be used in surface-mount designs?
No-JAN1N3611/TR is an axial-leaded through-hole device in the "A" glass package and is not suitable for SMT assembly. For surface-mount equivalents, Microsemi offers the 1N5614US–1N5622US series in MELF packages; however, those parts differ in qualification level and are not drop-in replacements for JAN1N3611/TR in MIL-spec applications.
