Product details
Overview
JANTXV1N6115US/TR from Microsemi (now Microchip) is a military-grade 1500W transient voltage suppression diode with 15V standoff voltage, 24.4V clamping voltage at 61.5A peak pulse current, and DO-214AB (SMC) package. It protects power rails in avionics power supplies against ESD and lightning-induced surges.
For engineers reviewing the JANTXV1N6115US/TR datasheet, JANTXV1N6115US/TR pinout, JANTXV1N6115US/TR application, or JANTXV1N6115US/TR equivalent, key selection criteria include peak pulse power rating, clamping ratio, junction capacitance under bias, operating temperature range, and MIL-PRF-19500/530 qualification status.
Technical Context
This unidirectional TVS diode operates as a shunt protection device, triggering when reverse voltage exceeds 15V (VWM) and clamping transients to ≤24.4V (VC) at IPP = 61.5A per 10/1000μs waveform. Its low dynamic impedance ensures rapid energy diversion during surge events.
Qualified to MIL-PRF-19500/530, JANTXV1N6115US/TR supports operation from –65°C to +175°C and exhibits <1.5pF junction capacitance at 0V, minimizing signal distortion in DC power line applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - Maximum continuous reverse working voltage before breakdown; sets upper limit for protected circuit DC rail. |
| VC @ IPP | 24.4 V at 61.5 A - Clamped voltage during 10/1000μs surge; determines maximum stress on downstream components. |
| PPPM | 1500 W - Peak pulse power handling capability; defines survivability under standardized lightning surge waveforms. |
| Junction Capacitance | <1.5 pF at 0 V - Minimal capacitive loading on DC power lines; avoids interference with high-speed control signals. |
| Operating Temp | –65°C to +175°C - Enables use in extended-temperature military and aerospace environments without derating. |
| Qualification | MIL-PRF-19500/530 - Confirms compliance with screening, testing, and reliability requirements for space- and defense-critical applications. |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, cathode-banded end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input side of protected DC rail | Connected to power source or upstream trace; carries normal load current only during surge conduction. |
| Cathode | Return path to ground or reference | Provides low-impedance path to divert surge current away from sensitive loads during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| 1500W peak pulse power | Enables robust protection against IEC 61000-4-5 Level 4 (4kV) and MIL-STD-461G CS115 surges without failure. |
| Low clamping ratio (VC/VWM = 1.63) | Reduces voltage overshoot margin required across protected ICs, allowing tighter design margins for 12–15V systems. |
| MIL-PRF-19500/530 qualification | Guarantees lot traceability, burn-in, temperature cycling, and hermeticity testing per military reliability standards. |
| DO-214AB package | Supports automated SMT placement and reflow; provides mechanical ruggedness and thermal dissipation suitable for high-vibration platforms. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6115US/TR | Commercial-grade variant; lacks MIL-PRF-19500/530 screening and extended temperature range. | Approved for non-mission-critical industrial systems only; not rated for flight or space use. | Select JANTX1N6115US/TR only if full military qualification is unnecessary and cost sensitivity outweighs reliability requirements. |
| 1.5KE15A | Same VWM and VC, but TO-218 package; lower thermal mass and no MIL qualification. | Used in commercial telecom power supplies; unsuitable for high-vibration or hermetic sealing requirements. | Choose 1.5KE15A only for cost-driven, non-military applications where SMC footprint and extended temp are not required. |
Compared with JANTX1N6115US/TR and 1.5KE15A, JANTXV1N6115US/TR delivers verified performance under MIL-specified environmental stress, enabling use in safety-critical avionics and space hardware where failure is not an option.

FAQ
What is the clamping voltage of JANTXV1N6115US/TR at its rated peak pulse current?
JANTXV1N6115US/TR clamps to 24.4 V at 61.5 A peak pulse current (10/1000 μs waveform). This value is measured and guaranteed per MIL-PRF-19500/530 test conditions and defines the maximum voltage imposed on protected circuitry during surge events. The clamping performance remains stable across its full operating temperature range.
Is JANTXV1N6115US/TR qualified for space applications?
JANTXV1N6115US/TR is MIL-PRF-19500/530 qualified and commonly used in space-qualified power systems, though formal QML-V listing requires additional radiation testing documentation. Its hermetic DO-214AB package, extended temperature range (–65°C to +175°C), and lot traceability make JANTXV1N6115US/TR suitable for LEO satellite power conditioning where radiation tolerance is managed at the system level.
Does JANTXV1N6115US/TR have polarity marking, and how is it identified?
Yes, JANTXV1N6115US/TR uses standard DO-214AB polarity marking: a white band on the cathode end. During PCB layout, the banded end must connect to ground or the lower-potential node. This orientation ensures proper unidirectional clamping behavior and prevents reverse-bias leakage in normal operation of JANTXV1N6115US/TR.
What is the maximum junction capacitance of JANTXV1N6115US/TR, and why does it matter?
JANTXV1N6115US/TR exhibits less than 1.5 pF junction capacitance at 0 V bias. This ultra-low capacitance prevents signal coupling and filtering distortion on DC power rails, especially critical in avionics systems where clean 15V bias supplies feed high-speed ADCs and FPGA I/O banks. Low capacitance also minimizes EMI generation during transient conduction in JANTXV1N6115US/TR.
Can JANTXV1N6115US/TR replace JANTX1N6115US/TR in existing designs?
JANTXV1N6115US/TR is physically and electrically compatible with JANTX1N6115US/TR-same DO-214AB package, pinout, and electrical specs-but adds MIL-PRF-19500/530 qualification, extended temperature range, and enhanced screening. Replacing JANTX1N6115US/TR with JANTXV1N6115US/TR requires no PCB changes and improves reliability in mission-critical deployments of JANTXV1N6115US/TR.
