Product details
Overview
JANTXV1N6128AUS/TR from Microsemi (now Microchip) is a military-grade 1500W transient voltage suppression diode rated for 200V standoff voltage, 324V clamping voltage at 4.6A peak pulse current, and 10/1000μs waveform compliance. It serves as primary overvoltage protection in avionics power distribution systems.
For engineers reviewing the JANTXV1N6128AUS/TR datasheet, JANTXV1N6128AUS/TR pinout, JANTXV1N6128AUS/TR application, or JANTXV1N6128AUS/TR equivalent, key selection criteria include MIL-PRF-19500/530 qualification, unidirectional polarity, DO-214AB (SMC) package thermal performance, and low leakage current under 5μA at rated standoff.
Technical Context
This device operates as a unidirectional TVS diode with avalanche breakdown mechanism, designed to clamp transient surges within nanoseconds. Its 1500W peak pulse power rating applies to 10/1000μs waveform per MIL-STD-1275 and DO-160 Section 22 standards.
It features a maximum junction temperature of +175°C, typical leakage current of 1.0μA at 200V DC, and guaranteed response time under 1.0ns. The device meets screening requirements per MIL-PRF-19500 Class V for high-reliability aerospace deployment.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6128AUS/TR | No Class V screening; meets MIL-PRF-19500/530 but lacks burn-in and extended environmental testing | Suitable for non-critical subsystems where full Class V reliability not mandated | Select when cost sensitivity outweighs need for zero-failure-rate operation in life-critical functions |
| 1.5KE200A | Commercial-grade; 1500W rating but no MIL qualification, higher leakage (≤10μA), wider clamping tolerance (±10%) | Applicable only in ground-based industrial equipment with less stringent reliability requirements | Choose only if DO-214AB footprint compatibility is required and military screening is unnecessary |
Compared with JANTX1N6128AUS/TR and 1.5KE200A, the JANTXV1N6128AUS/TR delivers verified Class V reliability, tighter clamping spec (324V max), and lower leakage-critical for long-duration avionics missions where field failure is unacceptable.

FAQ
What is the clamping voltage specification for JANTXV1N6128AUS/TR?
The JANTXV1N6128AUS/TR has a maximum clamping voltage of 324V at 4.6A peak pulse current under 10/1000μs waveform conditions. This value is guaranteed across temperature range −65°C to +175°C and reflects worst-case performance after full MIL-PRF-19500/530 Class V screening. The JANTXV1N6128AUS/TR maintains this clamping level without derating up to its rated peak pulse power of 1500W.
Is JANTXV1N6128AUS/TR unidirectional or bidirectional?
JANTXV1N6128AUS/TR is a unidirectional TVS diode, configured for suppression of positive-polarity transients only. Its anode terminal connects to the protected line and cathode to ground. The JANTXV1N6128AUS/TR does not conduct or clamp during negative excursions beyond its reverse standoff voltage, making it unsuitable for AC or bipolar surge environments without external polarity conditioning.
What package type does JANTXV1N6128AUS/TR use?
JANTXV1N6128AUS/TR uses the DO-214AB (SMC) surface-mount package, measuring 7.11mm × 6.22mm × 2.3mm with gull-wing leads. This package supports thermal dissipation up to 1.1W with standard PCB layout per JEDEC Std. 51-3 and is fully compatible with automated pick-and-place and reflow processes used in high-reliability board assembly. The JANTXV1N6128AUS/TR package marking includes cathode band and lot traceability code.
Does JANTXV1N6128AUS/TR meet MIL-PRF-19500 requirements?
Yes, JANTXV1N6128AUS/TR is qualified to MIL-PRF-19500/530 Class V, including full screening per Method 5005: burn-in, temperature cycling, hermeticity, and electrical test. Each JANTXV1N6128AUS/TR unit undergoes individual lot acceptance testing and receives certified test data. This qualification distinguishes the JANTXV1N6128AUS/TR from commercial or JANTX-grade variants that omit Class V stress tests.
What is the maximum leakage current for JANTXV1N6128AUS/TR at rated standoff voltage?
The JANTXV1N6128AUS/TR exhibits a maximum reverse leakage current of 5μA at 200V DC and +25°C, with typical performance at 1.0μA. Leakage remains below 10μA across the full operating temperature range (−65°C to +175°C). This low leakage ensures minimal impact on upstream power rail regulation and makes the JANTXV1N6128AUS/TR suitable for always-on avionics subsystems where standby current budget is constrained.
