Product details
Overview
JANTX1N6144AUS/TR from Microsemi is a military-qualified, voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) designed for high-reliability circuit protection. It features a 9.1 V working peak standoff voltage (VWM), 11.40 V minimum breakdown voltage (V(BR)) at 100 mA, 16.9 V clamping voltage (VC) at 88.8 A peak pulse current (IPP), and 1500 W peak pulse power (10/1000 µs). It is used in avionics power bus surge suppression where failure tolerance is critical.
For engineers reviewing the JANTX1N6144AUS/TR datasheet, JANTX1N6144AUS/TR pinout, JANTX1N6144AUS/TR application, or JANTX1N6144AUS/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANTX qualification, bidirectional clamping behavior, hard-glass SQ-MELF package robustness, and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning-induced transients.
Technical Context
This TVS operates bidirectionally with symmetrical avalanche characteristics, enabling protection of AC-coupled or floating signal/power lines without polarity concerns. Its internal Category 1 metallurgical bonds and voidless hermetic glass construction ensure stable performance across -55 °C to +175 °C junction temperature range and immunity to moisture ingress or thermal cycling degradation.
The device delivers 1500 W peak pulse power under standardized 10/1000 µs waveform conditions, with thermal resistance from junction to end cap rated at 5.0 °C/W. Standby current remains ≤20 µA at 9.1 V VWM, supporting low-leakage system-level standby modes in mission-critical platforms.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1.5KE9.1A | DO-201 package; 9.1 V VWM; 1500 W PPP; but only commercial-grade, non-hermetic epoxy construction. | Lacks MIL-PRF-19500 qualification, Category 1 bonds, and hermetic seal-unsuitable for flight hardware or long-life deployments. | Select only for cost-sensitive ground-test fixtures or non-mission-critical industrial controls. |
| SMCJ9.0A | SMD SMC package; 9.0 V VWM; 1500 W PPP; RoHS-compliant; but plastic encapsulation and lower TJ max (+150 °C). | Not qualified to MIL-PRF-19500; limited to commercial/industrial use; higher moisture sensitivity and thermal resistance. | Acceptable for automotive ECUs or telecom infrastructure where JANTX reliability level is not mandated. |
Compared with 1.5KE9.1A and SMCJ9.0A, JANTX1N6144AUS/TR provides verified hermeticity, extended temperature operation (+175 °C), and full military screening-making it the sole choice when field failure risk must be reduced to <1 FIT over 10⁶ device-hours.

FAQ
What is the maximum clamping voltage of JANTX1N6144AUS/TR under a 10/1000 µs transient?
The JANTX1N6144AUS/TR has a maximum clamping voltage (VC) of 16.9 V when subjected to its rated peak pulse current of 88.8 A under the standard 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3013 and is guaranteed across the full -55 °C to +175 °C operating temperature range. The JANTX1N6144AUS/TR maintains this clamping performance without degradation after repeated surge events due to its Category 1 metallurgical bond structure.
Is JANTX1N6144AUS/TR suitable for bidirectional signal line protection?
Yes, JANTX1N6144AUS/TR is inherently bidirectional and requires no polarity orientation during placement. Its symmetrical avalanche characteristics allow it to protect AC-coupled interfaces, differential buses like RS-485 or MIL-STD-1553B, and ungrounded power rails equally in both directions. The JANTX1N6144AUS/TR achieves this without internal series diodes or asymmetric doping, delivering matched clamping thresholds (<±2% variation) across both polarities.
Does JANTX1N6144AUS/TR meet IEC61000-4-5 for lightning surge immunity?
Yes, JANTX1N6144AUS/TR provides protection against secondary effects of lightning per IEC61000-4-5, including combination wave (1.2/50 µs voltage, 8/20 µs current) surges up to 1500 W. Its 16.9 V clamping voltage at 88.8 A ensures downstream circuitry remains below safe operating limits during Level 3 (2 kV line-earth, 1 kV line-line) and Level 4 (4 kV line-earth, 2 kV line-line) tests. The JANTX1N6144AUS/TR's hermetic construction prevents parameter shift after repeated IEC61000-4-5 stress cycles.
What is the thermal resistance specification for JANTX1N6144AUS/TR?
JANTX1N6144AUS/TR has a thermal resistance from junction to end cap (RθJEC) of 5.0 °C/W, measured per MIL-STD-750 Method 1071. This low thermal resistance enables efficient heat transfer from the silicon junction through the tungsten slug and glass body into the PCB pad. When mounted on a 1-inch² copper area, the JANTX1N6144AUS/TR supports continuous off-state power dissipation up to 5.0 W at end-cap temperature ≤150 °C, with linear derating to zero at 175 °C.
How does the "A" suffix in JANTX1N6144AUS/TR affect its electrical parameters?
The "A" suffix in JANTX1N6144AUS/TR denotes tighter voltage tolerances: it specifies minimum breakdown voltage (V(BR)) and clamping voltage (VC) without the ±5% shifts applied to non-A versions. Specifically, JANTX1N6144AUS/TR guarantees V(BR) ≥11.40 V and VC ≤16.9 V, whereas the non-A variant would have 5% lower V(BR) min and 5% higher VC max. This ensures predictable clamping margins in precision protection designs where worst-case voltage excursions must be bounded.
