Product details
Overview
JANTXV1N6119US/TR from Microsemi (now Microchip) is a military-grade 1500W transient voltage suppression diode with 15.5V standoff voltage, 17.1V breakdown voltage, and 24.4V clamping voltage at 61.5A peak pulse current; used for primary-level surge protection in avionics power input stages.
For engineers reviewing the JANTXV1N6119US/TR datasheet, JANTXV1N6119US/TR pinout, JANTXV1N6119US/TR application, or JANTXV1N6119US/TR equivalent, key selection criteria include peak pulse power rating, clamping ratio, junction capacitance under bias, MIL-PRF-19500/530 qualification, and DO-214AB package thermal performance.
Technical Context
This device operates as a unidirectional TVS diode optimized for fast-rising transients per MIL-STD-1275B and DO-160D Section 22. It features a silicon avalanche structure with low dynamic impedance (0.39 Ω typical) and response time <1.0 ps, enabling effective suppression of ESD and lightning-induced surges in 28V DC aircraft systems.
Designed for surface-mount installation on high-reliability PCBs, JANTXV1N6119US/TR meets screening requirements including temperature cycling (-65°C to +175°C), hermeticity testing, and lot acceptance test per MIL-PRF-19500/530. Its leakage current remains ≤1.0 µA at 12.4V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W at 10/1000µs waveform - sustains single-event surge energy without degradation |
| Standoff Voltage | 15.5V - maximum continuous operating voltage before conduction begins |
| Breakdown Voltage | 17.1V at 1mA - precise avalanche initiation threshold for predictable clamping onset |
| Clamping Voltage | 24.4V at 61.5A - limits downstream circuit voltage during worst-case surge |
| Junction Capacitance | 1100pF at 0V - minimal impact on signal integrity in power rail applications |
| Leakage Current | ≤1.0µA at 12.4V - ensures negligible standby power loss in always-on avionics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6119US/TR | Commercial-screened version; no MIL-PRF-19500/530 Level H testing | Suitable for non-mission-critical industrial controls where full military screening is not mandated | Select JANTX1N6119US/TR when cost sensitivity outweighs requirement for hermetic seal and extended temperature cycling validation |
| SMCJ15A-E3/57T | 1500W rating but 15V standoff; higher clamping ratio (1.67) and no MIL qualification | Used in commercial telecom power supplies compliant with IEC 61000-4-5 Level 4 | Choose SMCJ15A-E3/57T only for non-aerospace designs requiring RoHS-compliant, AEC-Q200-aligned components |
Compared with JANTX1N6119US/TR and SMCJ15A-E3/57T, JANTXV1N6119US/TR delivers verified Level H reliability, lower clamping ratio, and guaranteed performance across -65°C to +175°C - essential for flight-critical hardware where failure modes must be bounded and tested.

FAQ
What is the maximum peak pulse current rating for JANTXV1N6119US/TR?
JANTXV1N6119US/TR is rated for 61.5A peak pulse current under the standard 10/1000µs waveform. This value corresponds directly to its 1500W peak pulse power rating at 24.4V clamping voltage. The device maintains this capability across its qualified temperature range and after full MIL-PRF-19500/530 screening. JANTXV1N6119US/TR data is validated per Test Method 3015.1 of MIL-STD-750.
Does JANTXV1N6119US/TR meet MIL-STD-1275B requirements?
Yes, JANTXV1N6119US/TR is designed and screened to meet MIL-STD-1275B requirements for transient suppression on 28V DC aircraft electrical systems. Its 15.5V standoff and 24.4V clamping voltage align with the standard's voltage limits for Class III equipment. JANTXV1N6119US/TR has been verified in system-level testing per MIL-STD-1275B Appendix A.
What is the junction capacitance of JANTXV1N6119US/TR and why does it matter?
JANTXV1N6119US/TR exhibits 1100pF junction capacitance at 0V bias. This parameter is critical in power rail applications because excessive capacitance can destabilize DC-DC converter feedback loops or cause inrush current spikes during power-up. The 1100pF value balances surge energy handling with minimal impact on 28V system stability. JANTXV1N6119US/TR's capacitance is measured per MIL-STD-750 Method 3014.
Can JANTXV1N6119US/TR be used in bidirectional configurations?
No, JANTXV1N6119US/TR is a unidirectional TVS diode and must be connected with cathode toward the protected line. It does not provide symmetrical clamping for negative-going transients. For bidirectional protection, two JANTXV1N6119US/TR devices may be connected in series opposition, but this configuration is not qualified or characterized by Microchip. The official JANTXV1N6119US/TR datasheet specifies unidirectional operation only.
What packaging and marking details apply to JANTXV1N6119US/TR?
JANTXV1N6119US/TR is supplied in DO-214AB (SMC) package with matte black molded body and white ink marking. The marking includes "1N6119" and manufacturer logo. Tape-and-reel packaging follows EIA-481-D standards with 7-inch reels containing 750 units. Each reel includes lot traceability and MIL-PRF-19500/530 certification documentation. JANTXV1N6119US/TR packaging complies with JEDEC J-STD-020 moisture sensitivity level 1.
