Product details
Overview
JANTXV1N6125US/TR from Microsemi (now Microchip) is a military-grade 1500W transient voltage suppression diode with a 25V standoff voltage, 38.5V clamping voltage at 43.5A peak pulse current, and DO-214AB (SMC) package. It protects power supply rails in avionics and missile guidance systems against ESD and lightning-induced surges.
For engineers reviewing the JANTXV1N6125US/TR datasheet, JANTXV1N6125US/TR pinout, JANTXV1N6125US/TR application, or JANTXV1N6125US/TR equivalent, key selection criteria include peak pulse power rating, clamping behavior under MIL-STD-461E CS115/CS116 waveforms, and compliance with JAN/JANTXV reliability screening per MIL-PRF-19500.
Technical Context
This unidirectional TVS diode operates in avalanche breakdown mode to clamp transient overvoltages above its VBR threshold. Its low dynamic impedance ensures rapid response (<1 ps) to fast-rising transients while maintaining stable VC across rated IPP.
Designed for high-reliability defense platforms, JANTXV1N6125US/TR undergoes 100% lot testing for surge capability, temperature cycling (−65°C to +175°C), and hermeticity per MIL-STD-750 Method 1071.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W at 10/1000μs waveform - sustains repeated lightning surge events without degradation |
| Standoff Voltage (VRWM) | 25V - blocks normal operating voltage while remaining non-conductive |
| Breakdown Voltage (VBR) | 27.8–30.8V at IBR = 1mA - precise threshold for controlled avalanche initiation |
| Clamping Voltage (VC) | 38.5V at IPP = 43.5A - limits downstream voltage stress during worst-case transients |
| Package | DO-214AB (SMC) - surface-mount footprint compatible with automated assembly and high thermal dissipation |
| Operating Temperature | −65°C to +175°C - supports operation in extreme environmental conditions of airborne systems |
Pinout & Package
DO-214AB (SMC) package with two terminals: Cathode (marked end) and Anode. Standard polarity marking aligns with MIL-PRF-19500 requirements for traceable device orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode | Transient current sink | Connected to protected line; conducts surge current to ground during overvoltage |
| Anode | Reference node | Typically tied to system ground; completes clamping path during avalanche conduction |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500 Qualified | Fully screened to JANTXV level including burn-in, life test, and radiation hardness assurance |
| Low Clamping Ratio (VC/VBR) | 1.32 - minimizes overvoltage margin between breakdown and clamping, reducing stress on downstream ICs |
| Hermetic Sealing | Prevents moisture ingress and corrosion in humid or salt-laden environments typical of naval and aerospace deployments |
| High Surge Current Capability | Withstands ≥43.5A peak pulse current per MIL-STD-461E CS115 - meets stringent platform-level EMC requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6125US | Same electrical specs but qualified to JANTX (not JANTXV) level; lacks extended temperature screening and radiation assurance | Suitable for ground-based military systems with less severe environmental requirements | Select JANTX1N6125US only when full JANTXV screening is not mandated by program spec |
| 1.5KE25A | Commercial-grade 1500W TVS; no MIL-qualified screening, wider VBR tolerance (23.7–26.3V), lower max TJ (150°C) | Applicable in industrial controls or telecom infrastructure where MIL-STD compliance is not required | Use 1.5KE25A only in non-military, non-safety-critical designs with relaxed reliability and temperature demands |

FAQ
What is the clamping voltage of JANTXV1N6125US/TR at its rated peak pulse current?
JANTXV1N6125US/TR has a maximum clamping voltage of 38.5V at 43.5A peak pulse current (10/1000μs waveform). This value is measured per MIL-STD-750 Method 3013 and ensures predictable overvoltage limiting during standardized surge events. The clamping performance is guaranteed across the full −65°C to +175°C operating range for JANTXV1N6125US/TR.
Is JANTXV1N6125US/TR compliant with MIL-PRF-19500?
Yes, JANTXV1N6125US/TR is fully qualified to MIL-PRF-19500 JANTXV level, including 100% lot testing for surge capability, temperature cycling, and hermeticity. Each device carries a JAN/JANTXV prefix and traceable lot documentation required for defense procurement. JANTXV1N6125US/TR meets all screening and test requirements defined in the specification.
What is the difference between JANTXV1N6125US/TR and JANTX1N6125US?
JANTXV1N6125US/TR undergoes extended reliability screening including radiation hardness assurance and operation up to +175°C, whereas JANTX1N6125US is qualified only to JANTX level with standard temperature range (−65°C to +150°C). Both share identical electrical parameters, but JANTXV1N6125US/TR provides higher confidence for flight-critical applications where JANTXV1N6125US/TR is specified.
Does JANTXV1N6125US/TR have a directional polarity marking?
Yes, JANTXV1N6125US/TR features a cathode band marking per DO-214AB (SMC) standard, indicating the cathode terminal. This marking is laser-etched and verified during MIL-PRF-19500 visual inspection. Correct orientation is critical for unidirectional clamping function in JANTXV1N6125US/TR installations.
Can JANTXV1N6125US/TR be used in parallel for higher surge handling?
No, JANTXV1N6125US/TR is not recommended for parallel operation due to mismatch in dynamic impedance and avalanche turn-on characteristics, which can cause current imbalance and premature failure. For higher energy handling, select a single higher-rated device such as JANTXV1N6130US/TR rather than paralleling multiple JANTXV1N6125US/TR units.
