Product details
Overview
JAN1N6141AUS/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), 6.9 V working standoff voltage (VWM), 8.65 V minimum breakdown voltage (VBR @ 150 mA), and 13.4 V clamping voltage (VC @ 111.9 A). It delivers ESD/EFT protection per IEC61000-4-2/4-4 and lightning secondary-effect suppression in high-reliability aerospace and defense power interfaces.
For engineers reviewing the JAN1N6141AUS/TR datasheet, JAN1N6141AUS/TR pinout, JAN1N6141AUS/TR application, or JAN1N6141AUS/TR equivalent, this part supports critical transient suppression in MIL-PRF-19500/516-compliant systems where failure tolerance, radiation hardness, and thermal stability up to +175 °C are mandatory design requirements.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses internal Category 1 metallurgical bonds within a hard-glass, voidless hermetic seal-enabling stable performance under thermal cycling and radiation exposure. Its triple-layer passivation and tungsten slug construction ensure robust surge handling across -55 °C to +175 °C junction temperature range.
The device exhibits a low 0.06 %/°C temperature coefficient of breakdown voltage (αVBR) and linear derating of off-state power above 150 °C at the end cap (TEC). Thermal resistance from junction to end cap is 5.0 °C/W, supporting high-power transient absorption without thermal runaway in constrained layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6141AUS | Higher screening level (JANTXV vs JAN): includes extended temperature testing, 100% lot acceptance testing, and tighter parametric limits on VC and IPP. | Required for mission-critical avionics where failure modes must be statistically bounded per MIL-HDBK-217F. | Select JANTXV version when full burn-in, radiation lot acceptance, and zero-defect screening are mandated by system safety plan. |
| 1N6141AUS (commercial) | No MIL-PRF-19500/516 qualification; RoHS-compliant matte-tin plating available; VC and IPP tolerances relaxed per nomenclature note (5% higher VC, 5% lower IPP). | Suitable for industrial test equipment or non-safety-critical telecom infrastructure where cost and RoHS compliance outweigh military screening needs. | Choose commercial 1N6141AUS only for non-mission-critical designs with verified thermal margin and no radiation or extreme temperature requirements. |

FAQ
What is the clamping voltage of JAN1N6141AUS/TR under a 10/1000 µs surge?
The clamping voltage (VC) of JAN1N6141AUS/TR is 13.4 V when subjected to its rated peak pulse current of 111.9 A under a 10/1000 µs waveform. This value is measured per MIL-STD-883 Method 3012 and guaranteed across the full -55 °C to +175 °C junction temperature range. The consistent VC ensures predictable protection margins for downstream 15 V-rated components in JAN1N6141AUS/TR-based designs.
Is JAN1N6141AUS/TR compatible with lead-free reflow processes?
JAN1N6141AUS/TR is qualified for solder reflow at 260 °C for 10 seconds per MIL-STD-202 Method 210, making it compatible with standard lead-free reflow profiles. However, its tin/lead terminal plating means it is not RoHS-compliant; for RoHS applications, the commercial 1N6141AUS variant with matte-tin plating must be selected instead of JAN1N6141AUS/TR.
Does JAN1N6141AUS/TR require polarity-aware PCB layout?
No-JAN1N6141AUS/TR is a bidirectional TVS with no polarity marking and symmetric electrical characteristics. Both terminals perform identically as anode/cathode depending on transient polarity, eliminating orientation constraints during automated placement. This simplifies PCB layout, reduces assembly errors, and supports compact two-pad footprints in JAN1N6141AUS/TR implementations.
How does the temperature coefficient affect JAN1N6141AUS/TR performance in wide-temperature environments?
JAN1N6141AUS/TR has a breakdown voltage temperature coefficient (αVBR) of 0.06 %/°C, meaning VBR increases by ~5.2 mV/°C over its operating range. This low drift ensures stable clamping onset across -55 °C to +175 °C, preventing premature conduction at cold temperatures or insufficient protection at high temperatures in JAN1N6141AUS/TR deployments.
Can JAN1N6141AUS/TR be used in parallel for higher surge capacity?
Parallel use of JAN1N6141AUS/TR devices is not recommended due to parameter mismatch (VBR, VC) causing current imbalance and potential single-device overstress. For higher surge ratings, Microsemi specifies discrete higher-power variants (e.g., JAN1N6165AUS) rather than paralleling JAN1N6141AUS/TR units-ensuring reliable, tested performance in mission-critical JAN1N6141AUS/TR applications.
