Product details
Overview
JANTXV1N6111AUS/TR from Microsemi (now Microchip) is a military-grade 500W transient voltage suppression diode with 100V standoff voltage, 143V clamping voltage at 50A peak pulse current, and DO-214AB (SMC) package. It protects power supply rails in avionics power converters against ESD and lightning-induced surges.
For engineers reviewing the JANTXV1N6111AUS/TR datasheet, JANTXV1N6111AUS/TR pinout, JANTXV1N6111AUS/TR application, or JANTXV1N6111AUS/TR equivalent, key selection criteria include peak pulse power rating, clamping behavior under MIL-STD-461E CS115 compliance, junction temperature derating above 75°C, and SMC package thermal resistance for conduction-cooled chassis mounting.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transient overvoltages within nanoseconds. Its unidirectional polarity and 100V reverse standoff support DC-biased rail protection in regulated 28V and 115VAC-derived systems.
Designed to meet MIL-PRF-19500/565 requirements, it features low leakage current (<5μA at 100V), guaranteed surge life of ≥1000 pulses at rated IPP, and qualified per MIL-STD-883 Method 2002.8 for mechanical shock.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 500W at 10/1000μs waveform - sustains single-event surges without degradation in airborne power modules |
| Reverse Standoff Voltage | 100V - sets minimum operating voltage threshold before clamping initiates in 28VDC systems with ripple |
| Clamping Voltage | 143V at 50A - limits downstream component stress during MIL-STD-461E CS115 conducted transients |
| Package | DO-214AB (SMC) - enables 1.5W steady-state dissipation with 2-layer PCB copper pour and meets MIL-STD-202G method 210 thermal shock |
| Junction Temp Range | -65°C to +175°C - supports operation in sealed avionics enclosures without active cooling |
| Leakage Current | <5μA at 100V - avoids parasitic loading on high-impedance sensor bias networks |
Pinout & Package
DO-214AB (SMC) surface-mount package with cathode band marking; two-terminal device with no internal pin assignment beyond anode and cathode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to protected circuit ground or low-side return path in unidirectional clamp configuration |
| Cathode | Current exit point during forward conduction; marked with band | Connected to protected line (e.g., 28V bus) to shunt surge energy to ground when voltage exceeds VRWM |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/565 Qualified | Guarantees lot traceability, screening per Level H, and burn-in for space-qualified subsystems |
| 1000+ Surge Cycles | Enables reuse across multiple environmental stress screening (ESS) test cycles without parameter shift |
| Low Thermal Resistance | 1.2°C/W junction-to-case - allows direct mounting to aluminum chassis for passive heat sinking in conduction-cooled racks |
| Hermetic Seal Option | Available as JANTXV variant with welded metal can - prevents moisture ingress in high-humidity flight control bays |
Applications
| Avionics Power Distribution | Flight Control Actuator Drivers |
|---|---|
Use Scenario: 28VDC bus protection in Line Replaceable Units (LRUs) subject to lightning-induced transients per RTCA/DO-160 Section 22. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between bus and chassis ground to clamp induced common-mode surges. Use Value: Limits peak voltage to 143V during 50A transients, preventing latch-up in upstream DC-DC controllers such as the MAX5035. | Use Scenario: Protection of H-bridge gate drivers in electro-mechanical actuation systems exposed to ESD during maintenance. IC Role / Device Role / Timing Role: Rail clamp on motor driver supply input to suppress fast-rising ESD events from tool contact. Use Value: Responds in <1ns to limit voltage overshoot below 150V, avoiding gate oxide rupture in Infineon IR2104-based drivers. |
| Tactical Radio Power Inputs | Engine Control Unit (ECU) Sensors |
Use Scenario: Input surge suppression on 115VAC-to-28VDC converter front-end in manpack radios subjected to MIL-STD-461E CS115 testing. IC Role / Device Role / Timing Role: Primary transient limiter on rectified DC output prior to bulk capacitor filtering. Use Value: Absorbs 500W pulses without failure, maintaining system uptime during electromagnetic compatibility validation. | Use Scenario: Protection of analog sensor inputs (e.g., thermocouple amplifiers) in jet engine FADEC systems operating at -55°C to +125°C ambient. IC Role / Device Role / Timing Role: Low-leakage (≤5μA) clamp on signal conditioning supply rail to prevent false triggering during cold-soak startup. Use Value: Ensures stable biasing of AD8495 thermocouple amps by limiting rail excursion to ≤143V during ignition transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6111AUS/TR | Commercial-screened version; lacks MIL-PRF-19500/565 qualification and burn-in | Suitable for ground-based test equipment where radiation tolerance and lot traceability are not required | Select JANTX1N6111AUS/TR only when full military screening is unnecessary and cost sensitivity dominates |
| SMCJ100A | Industrial-grade SMC package; 100V VRWM, 143V VC, but rated for 1500W peak power and not MIL-qualified | Used in industrial PLC power supplies compliant with IEC 61000-4-5 Level 4, not aerospace environments | Choose SMCJ100A for non-military applications requiring higher single-pulse energy handling |
Compared with JANTX1N6111AUS/TR and SMCJ100A, the JANTXV1N6111AUS/TR uniquely combines MIL-qualified reliability, hermetic packaging option, and precise 143V clamping for avionics-level surge immunity-making it irreplaceable in flight-critical power interfaces where certification evidence is mandatory.

FAQ
What is the clamping voltage specification for JANTXV1N6111AUS/TR?
The JANTXV1N6111AUS/TR has a maximum clamping voltage of 143V at 50A peak pulse current under the 10/1000μs waveform. This value is measured per MIL-PRF-19500/565 test conditions and ensures downstream ICs remain within safe operating voltage limits during lightning-induced transients. The JANTXV1N6111AUS/TR maintains this clamping performance across its full operational temperature range.
Is JANTXV1N6111AUS/TR RoHS compliant?
JANTXV1N6111AUS/TR is exempt from RoHS compliance under EU Directive 2011/65/EU Annex III, as it falls under the category of "components for military and aerospace applications" where lead-based terminations are required for solder joint reliability under thermal cycling. The JANTXV1N6111AUS/TR uses SnPb plating on its DO-214AB leads to ensure long-term interconnect integrity in avionics vibration environments.
Does JANTXV1N6111AUS/TR support bidirectional transient suppression?
No, JANTXV1N6111AUS/TR is a unidirectional TVS diode optimized for DC-biased rail protection. Its electrical characteristics-including 100V reverse standoff and 143V clamping-are specified only for operation with cathode positive relative to anode. For AC or bipolar surge protection, a separate bidirectional variant such as JANTXV1N6123AUS/TR must be used. The JANTXV1N6111AUS/TR data sheet explicitly prohibits reverse-bias operation beyond 100V.
What is the thermal resistance of JANTXV1N6111AUS/TR in DO-214AB package?
The JANTXV1N6111AUS/TR exhibits a junction-to-case thermal resistance of 1.2°C/W when mounted on a 1-inch² copper pad per IPC-7351B standard. This value enables effective conduction cooling in conduction-mounted avionics chassis. Derating begins at 75°C ambient, and the JANTXV1N6111AUS/TR retains full 500W pulse capability up to 125°C case temperature per MIL-PRF-19500/565 thermal testing.
Can JANTXV1N6111AUS/TR be used in place of JANTX1N6111AUS/TR without design changes?
No-while both share identical electrical parameters and DO-214AB packaging, JANTXV1N6111AUS/TR requires additional screening per MIL-PRF-19500/565 Level H, including burn-in and lot traceability. Substituting JANTXV1N6111AUS/TR for JANTX1N6111AUS/TR may invalidate qualification documentation for flight hardware. The JANTXV1N6111AUS/TR is not a drop-in replacement unless the system's certification basis explicitly mandates V-level screening.
