Product details
Overview
JANTXV1N6126US/TR from Microsemi (now Microchip) is a military-grade 500W transient voltage suppression diode rated for 180V standoff voltage, 200V breakdown voltage, and 224V clamping voltage at 20A peak pulse current; used in avionics power rail protection against ESD and lightning-induced surges.
For engineers reviewing the JANTXV1N6126US/TR datasheet, JANTXV1N6126US/TR pinout, JANTXV1N6126US/TR application, or JANTXV1N6126US/TR equivalent, key selection criteria include peak pulse power rating, clamping ratio, junction capacitance under bias, MIL-PRF-19500/530 qualification status, and DO-213AA package thermal performance.
Technical Context
This unidirectional TVS diode operates with a fast response time of <1.0 ps to transient overvoltage events and maintains stable clamping performance across -65°C to +175°C operating temperature range. Its silicon avalanche structure enables repeatable surge handling per MIL-STD-883 Method 3015.7.
The JANTXV1N6126US/TR complies with MIL-PRF-19500/530 Class V requirements and is tested for hermeticity, burn-in, and lot acceptance per MIL-STD-750 Method 1071. It exhibits low leakage current (<5 µA at 144V) and minimal capacitance (120 pF at 0 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6126US/TR | Non-verified screening level; lacks MIL-PRF-19500/530 Class V qualification and hermeticity testing | Acceptable for non-mission-critical ground test equipment where full MIL spec not mandated | Select only when cost sensitivity outweighs reliability assurance in flight-critical systems |
| 1N6126US/TR | Commercial grade; no military screening, wider parametric tolerances (±10% VBR), no temperature cycling validation | Limited to benign-environment industrial controls with ambient <85°C and no surge certification required | Not suitable for aerospace or defense deployment; use only in non-safety-related prototypes |
Compared with JANTX1N6126US/TR and 1N6126US/TR, the JANTXV1N6126US/TR delivers verified hermetic sealing, tighter VBR tolerance (±5%), and guaranteed operation at +175°C-critical for sustained reliability in sealed, high-temperature avionics bays.
