Product details
Overview
JANS1N6141US/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), and 13.4 V clamping voltage (VC) at 111.9 A peak pulse current. It operates across –55 °C to +175 °C and is used in avionics power rail protection where failure tolerance and radiation hardness are mandatory.
For engineers reviewing the JANS1N6141US/TR datasheet, JANS1N6141US/TR pinout, JANS1N6141US/TR application, or JANS1N6141US/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANS qualification, bidirectional clamping behavior, 5.0 °C/W junction-to-end-cap thermal resistance, and compatibility with high-reliability PCB assembly under MIL-STD-202 and MIL-STD-750 test conditions.
Technical Context
This device implements a silicon avalanche diode structure optimized for fast response (<1 ns) to transient overvoltages, with triple-layer passivation and Category 1 metallurgical bonds ensuring mechanical robustness under thermal cycling and shock. Its bidirectional symmetry eliminates polarity concerns in AC-coupled or floating signal paths.
Designed for hard-glass SQ-MELF packaging, JANS1N6141US/TR uses tungsten slugs and tin/lead-plated copper terminals to sustain 260 °C solder exposure per EIA-481-B tape-and-reel handling. It meets IEC61000-4-2 (ESD), IEC61000-4-4 (EFT), and select IEC61000-4-5 lightning surge levels without derating in controlled thermal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.9 V - Maximum continuous reverse/forward voltage before conduction; sets minimum system operating margin for 12 V rail protection. |
| VC @ IPP | 13.4 V at 111.9 A - Clamped voltage during 10/1000 µs surge; defines maximum stress on downstream ICs. |
| PPP | 1500 W - Peak pulse power rating; enables suppression of high-energy transients without thermal runaway. |
| RθJEC | 5.0 °C/W - Junction-to-end-cap thermal resistance; supports direct heat sinking via end-cap mounting in conduction-cooled systems. |
| TJ/TSTG | –55 °C to +175 °C - Full military temperature range; validated for operation in jet engine bays and space-qualified electronics. |
| αV(BR) | 0.06 %/°C - Temperature coefficient of breakdown voltage; ensures stable clamping threshold across extreme ambient shifts. |
Pinout & Package
SQ-MELF (C-package) surface-mount hermetically sealed glass case with square-end-cap terminals; no polarity marking due to bidirectional symmetry; weight ≈1100 mg; dimensions: BD = 0.183–0.202 in (4.65–5.13 mm), BL = 0.205–0.245 in (5.21–6.22 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either end functions identically as conduction path during positive or negative transients; no orientation required during placement. |
| End Cap (both ends) | Thermal and electrical terminal | Provides primary heat dissipation path and low-inductance current return; requires full-surface solder contact for rated PPP performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6141US | Same electrical specs but qualified to JANTXV level; lower screening rigor than JANS (no radiation testing, reduced burn-in duration). | Approved for ground-based military systems with less stringent radiation or long-term reliability requirements. | Select when full JANS radiation hardness and 20-year shelf-life validation are not mandated. |
| 1N6141AUS (commercial) | Identical VWM, VC, and PPP, but lacks MIL-PRF-19500/516 qualification and RoHS-compliant matte-tin plating only. | Suitable for non-military industrial controls or test equipment where cost and lead time outweigh qualification needs. | Choose for prototyping or commercial derivatives where JANS traceability and extended temperature validation are unnecessary. |
Compared with JANS1N6141US/TR, JANTXV1N6141US offers faster procurement and lower cost for non-space applications, while 1N6141AUS provides identical clamping performance without military screening-enabling design reuse across commercial and defense variants with minimal requalification effort.

FAQ
What is the clamping voltage of JANS1N6141US/TR at its rated peak pulse current?
JANS1N6141US/TR has a maximum clamping voltage (VC) of 13.4 V at 111.9 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is guaranteed per MIL-PRF-19500/516 test conditions and reflects worst-case conduction across the full temperature range. The JANS1N6141US/TR maintains this clamping performance without degradation after repeated surge events when properly heatsunk via end-cap mounting.
Is JANS1N6141US/TR compatible with lead-free reflow processes?
JANS1N6141US/TR is rated for 260 °C solder temperature for 10 seconds, meeting J-STD-020 moisture sensitivity level 1 requirements. However, its standard termination is tin/lead (SnPb); RoHS-compliant matte-tin plating is only available on commercial-grade 1N6141AUS, not JANS1N6141US/TR. Therefore, JANS1N6141US/TR requires SnPb-compatible reflow profiles and is not qualified for Pb-free assembly unless explicitly re-qualified by the customer per MIL-STD-202 method 210.
Does JANS1N6141US/TR require polarity-aware PCB layout?
No-JANS1N6141US/TR is a bidirectional TVS with symmetrical avalanche characteristics, meaning either end functions identically as anode or cathode depending on transient polarity. The device carries no polarity marking, and PCB footprint design must accommodate rotation-invariant placement. This eliminates orientation errors during automated placement and simplifies layout for AC-coupled or floating circuits where voltage reversals occur.
How does the thermal resistance RθJEC of JANS1N6141US/TR impact its surge handling capability?
JANS1N6141US/TR specifies a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, enabling efficient heat transfer from the die to the PCB pads or heatsink through direct end-cap contact. This allows sustained 1500 W surge dissipation without exceeding the 175 °C maximum junction temperature-provided both end caps are fully soldered to thermally robust copper areas. Inadequate pad thermal mass increases effective RθJA, risking thermal runaway during repetitive surges.
What standards compliance is verified for JANS1N6141US/TR?
JANS1N6141US/TR is qualified to MIL-PRF-19500/516 for JANS reliability level and demonstrates compliance with IEC61000-4-2 (±15 kV air, ±8 kV contact ESD), IEC61000-4-4 (40 A/m EFT), and select IEC61000-4-5 (lightning surge) levels per test reports. It is also non-sensitive to ESD per MIL-STD-750 method 1020 and inherently radiation-hard per Microsemi MicroNote 050-verified data that applies specifically to JANS1N6141US/TR, not inferred from family-level claims.
