Product details
Overview
JANS1N6141AUS/TR from Microsemi is a hermetically sealed, voidless, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANS level. It provides 6.9 V working standoff voltage (VWM), 8.65 V minimum breakdown voltage (V(BR)) at 150 mA, 13.4 V clamping voltage (VC) at 111.9 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform - deployed in aerospace power bus protection and avionics interface circuits.
For engineers reviewing the JANS1N6141AUS/TR datasheet, JANS1N6141AUS/TR pinout, JANS1N6141AUS/TR application, or JANS1N6141AUS/TR equivalent, key selection criteria include military-grade reliability (JANS qualification), bidirectional surge suppression capability, hard-glass package robustness, IEC61000-4-2/4-4/4-5 compliance, and thermal resistance of 5.0 °C/W junction-to-end cap.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses internal Category 1 metallurgical bonds for high-reliability interconnect integrity. Its voidless hermetic glass construction ensures long-term stability under thermal cycling and radiation exposure per MicroNote 050.
The device delivers 1500 W peak pulse power at 25 °C for 10/1000 µs transients, with linear derating above 150 °C end-cap temperature to zero at 175 °C. Standby current is limited to 100 µA at 6.9 V VWM, and clamping occurs at 13.4 V under 111.9 A IPP.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6141AUS | Same electrical specs but qualified to JANTXV level; lower screening rigor than JANS (no radiation test) | Approved for ground-based military systems where total ionizing dose (TID) is not a concern | Select when full JANS radiation hardness is unnecessary and cost reduction is prioritized |

FAQ
What is the clamping voltage of JANS1N6141AUS/TR under maximum surge conditions?
The JANS1N6141AUS/TR has a maximum clamping voltage (VC) of 13.4 V when subjected to its rated peak pulse current (IPP) of 111.9 A for a 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3013 and ensures downstream circuitry remains within safe operating limits during transient events. The JANS1N6141AUS/TR maintains this clamping performance across its full operating temperature range.
Is JANS1N6141AUS/TR suitable for space applications?
Yes, the JANS1N6141AUS/TR is inherently radiation-hardened per Microsemi MicroNote 050 and qualified to MIL-PRF-19500/516 at JANS level, which includes total ionizing dose (TID) testing. Its voidless hermetic glass package and Category 1 metallurgical bonds make the JANS1N6141AUS/TR appropriate for low-Earth orbit and deep-space missions where single-event effects and long-term parametric stability are critical.
What is the thermal resistance specification for JANS1N6141AUS/TR?
The JANS1N6141AUS/TR has a thermal resistance of 5.0 °C/W from junction to end cap (RθJEC), measured under standard test conditions. This parameter defines how efficiently heat transfers from the silicon junction to the external mounting surface and is essential for calculating safe pulse repetition rates and steady-state power dissipation. The JANS1N6141AUS/TR requires proper PCB thermal pad design per the manufacturer's recommended footprint to maintain this rating.
Does JANS1N6141AUS/TR have polarity markings?
No, the JANS1N6141AUS/TR is a bidirectional TVS diode with no polarity marking on the SQ-MELF package. Either end functions as anode or cathode depending on the instantaneous polarity of the transient event. This eliminates orientation errors during automated placement and simplifies board layout for symmetric protection schemes. The JANS1N6141AUS/TR's bidirectional behavior is intrinsic to its construction and verified per MIL-PRF-19500/516 test requirements.
What standards does JANS1N6141AUS/TR meet for ESD and surge immunity?
The JANS1N6141AUS/TR meets IEC61000-4-2 (ESD) up to Level 4 (15 kV air discharge), IEC61000-4-4 (EFT) at 4 kV, and IEC61000-4-5 (surge) for select coupling levels. These capabilities are enabled by its 1500 W peak pulse power rating and fast response time (<1 ns). Compliance is inherent to the JANS1N6141AUS/TR's design and confirmed through qualification testing per MIL-PRF-19500/516, not derived from external system-level validation.
