Product details
Overview
JANTXV1N6162US/TR from Microsemi is a military-qualified, voidless hermetically sealed bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF package, rated for 1500 W peak pulse power (10/1000 µs), 51.7 V working standoff voltage (VWM), and 97.1 V clamping voltage (VC) at 15.4 A peak pulse current. It operates across –55 °C to +175 °C and is used in high-reliability avionics power rail protection.
For engineers reviewing the JANTXV1N6162US/TR datasheet, JANTXV1N6162US/TR pinout, JANTXV1N6162US/TR application, or JANTXV1N6162US/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANTXV qualification, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning surge immunity.
Technical Context
This TVS employs hard-glass construction with internal Category 1 metallurgical bonds to ensure radiation hardness and long-term reliability under thermal cycling and mechanical stress. Its bidirectional architecture provides symmetrical clamping without polarity marking, enabling placement flexibility on unidirectional or AC-coupled lines.
The device delivers stable breakdown at 64.6 V (min) with ±5% tolerance (A-suffix), temperature coefficient of 0.100 %/°C, and low standby leakage (<5 µA at VWM). It sustains 1500 W transient energy while maintaining clamping integrity up to TJ = 175 °C via direct junction-to-end-cap thermal path.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1500 W - withstands high-energy transients without degradation in aerospace power bus protection |
| Working Standoff Voltage (VWM) | 51.7 V - maximum continuous DC or repetitive peak voltage before conduction begins |
| Clamping Voltage (VC @ IPP) | 97.1 V at 15.4 A - limits downstream voltage during surge to protect 100 V-rated components |
| Breakdown Voltage (VBR min) | 64.6 V @ 20 mA - ensures reliable turn-on above normal operating rail with margin |
| Junction Temperature Range | –55 °C to +175 °C - supports operation in extreme environments including engine bays and space-grade enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6162AUS (commercial) | No MIL-PRF-19500/516 qualification; same VWM, VC, and PPP but lacks JANTXV screening | Suitable for ground-test equipment or non-flight prototypes where radiation hardness and extended temp range not required | Select only when full military screening and 175 °C operation are unnecessary |
| JANTXV1N6161US/TR | Lower VWM (47.1 V), lower VC (85.3 V), higher IPP (17.6 A); identical package and qualification level | Better suited for 24 V systems requiring tighter clamping margin below 100 V | Choose when system nominal voltage is ≤28 V and clamping headroom must be minimized |
Compared with JANTXV1N6162US/TR, the commercial 1N6162AUS omits military screening and high-temp validation, while JANTXV1N6161US/TR trades standoff voltage for enhanced clamping precision-making each optimal for distinct voltage-class and assurance-tier requirements.

FAQ
What is the clamping voltage of JANTXV1N6162US/TR at its rated peak pulse current?
The JANTXV1N6162US/TR has a maximum clamping voltage (VC) of 97.1 V at 15.4 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream component voltage rating selection in protected circuits. The JANTXV1N6162US/TR maintains this clamping performance without degradation after repeated surge events when mounted per recommended pad layout.
Is JANTXV1N6162US/TR suitable for bidirectional signal line protection?
Yes, JANTXV1N6162US/TR is inherently bidirectional due to its symmetrical avalanche structure and absence of polarity marking. It provides identical clamping behavior regardless of voltage polarity, making it appropriate for AC-coupled interfaces, differential buses, or any application where transient direction cannot be predicted-such as antenna feedlines or isolated sensor outputs. The JANTXV1N6162US/TR does not require orientation verification during assembly.
Does JANTXV1N6162US/TR meet IEC61000-4-5 for lightning surge immunity?
Yes, JANTXV1N6162US/TR is validated for protection against secondary effects of lightning per select levels of IEC61000-4-5, as stated in the official Microsemi documentation. Its 1500 W peak pulse power rating and low clamping voltage enable effective energy diversion for combination wave (1.2/50 µs voltage, 8/20 µs current) surges up to 6 kV open-circuit. The JANTXV1N6162US/TR achieves this while maintaining parameter stability after surge testing per test plan requirements.
What is the thermal resistance specification for JANTXV1N6162US/TR?
JANTXV1N6162US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, measured under standardized conditions. This low value reflects its hard-glass construction and tungsten slug design, enabling efficient heat transfer from the junction to the PCB pads. For sustained operation near maximum ambient temperatures, the JANTXV1N6162US/TR requires adequate copper area and optional adhesive bonding per the recommended pad layout to maintain junction temperature below 175 °C.
How does the JANTXV1N6162US/TR differ from the commercial 1N6162AUS variant?
JANTXV1N6162US/TR differs from 1N6162AUS in qualification level, screening, and temperature capability: it is fully qualified to MIL-PRF-19500/516 at JANTXV level-including extended temperature operation (–55 °C to +175 °C), radiation hardness, and rigorous lot acceptance testing. The 1N6162AUS is commercial-grade only, with narrower temperature range and no military screening. Both share identical electrical parameters and SQ-MELF packaging, but the JANTXV1N6162US/TR is the only version approved for flight hardware.
