Product details
Overview
JANS1N6170US/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), 114.0 V working standoff voltage (VWM), and 206.3 V clamping voltage (VC @ 7.3 A). It operates across –55 °C to +175 °C and is used in high-reliability aerospace power bus protection.
For engineers reviewing the JANS1N6170US/TR datasheet, JANS1N6170US/TR pinout, JANS1N6170US/TR application, or JANS1N6170US/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANS qualification, Category 1 metallurgical bonds, triple-layer passivation, and IEC61000-4-5 lightning surge compliance for hardened avionics interfaces.
Technical Context
This device functions as a bidirectional voltage-clamping protector with no polarity marking, relying on symmetric avalanche breakdown in both directions. Its hard-glass SQ-MELF construction enables stable thermal resistance (RθJEC = 5.0 °C/W) and robust impulse handling up to 1500 W at 25 °C ambient.
It delivers ESD immunity per MIL-STD-750 Method 1020 and meets IEC61000-4-2 (ESD), -4-4 (EFT), and select levels of -4-5 (lightning-induced surges). Standby current is ≤5 µA at VWM, and temperature coefficient of V(BR) is +0.105 %/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 114.0 V - Maximum continuous reverse/forward voltage before conduction begins; defines safe operating window for protected circuitry. |
| VC @ IPP | 206.3 V @ 7.3 A - Clamped voltage during 10/1000 µs surge; limits transient stress on downstream components. |
| PPP | 1500 W - Peak pulse power rating for standardized 10/1000 µs waveform; determines surge energy absorption capability. |
| TJ/TSTG | –55 °C to +175 °C - Full military-grade junction and storage temperature range; supports operation in extreme environmental conditions. |
| RθJEC | 5.0 °C/W - Junction-to-end-cap thermal resistance; enables accurate thermal design for high-power pulse dissipation. |
| αV(BR) | +0.105 %/°C - Temperature coefficient of breakdown voltage; quantifies V(BR) drift over temperature for precision clamping stability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6170US | Same VWM, VC, PPP, and package; qualified to JANTXV level (lower screening rigor than JANS, no radiation assurance). | Approved for ground-based military systems but not spaceflight or nuclear-hardened platforms. | Select when full JANS screening is unnecessary and cost sensitivity is higher. |
| 1N6170AUS | Commercial-grade version; identical electrical specs but lacks MIL-PRF-19500/516 qualification and Category 1 bonds. | Restricted to non-safety-critical commercial avionics or test equipment where reliability requirements are relaxed. | Choose only for prototyping or non-mission-critical subsystems with controlled environment. |
Compared with JANTXV1N6170US and 1N6170AUS, the JANS1N6170US/TR provides verified radiation hardness, full JANS screening, and Category 1 metallurgical bonds-making it the sole option for flight-qualified spacecraft and nuclear-command electronics where failure is unacceptable.

FAQ
What is the clamping voltage of JANS1N6170US/TR at its rated peak pulse current?
The JANS1N6170US/TR has a maximum clamping voltage (VC) of 206.3 V at its rated peak pulse current (IPP) of 7.3 A for a 10/1000 µs waveform. This value is measured under standard test conditions per MIL-PRF-19500/516 and defines the upper voltage limit imposed on protected circuits during surge events. The JANS1N6170US/TR maintains this clamping performance across its full operating temperature range.
Is JANS1N6170US/TR suitable for bidirectional AC line protection?
Yes, the JANS1N6170US/TR is explicitly designed as a bidirectional TVS with no polarity marking, making it suitable for AC line protection such as 115 VAC aircraft bus interfaces. Its symmetric breakdown behavior ensures equal clamping in both directions, and its 114.0 V working standoff voltage allows safe operation across RMS AC peaks up to ~160 V. The JANS1N6170US/TR's SQ-MELF package supports reliable mounting in high-vibration environments typical of aviation systems.
Does JANS1N6170US/TR meet IEC61000-4-5 for lightning surge immunity?
Yes, the JANS1N6170US/TR provides protection from secondary effects of lightning per select levels of IEC61000-4-5, as documented in Microsemi's T4-LDS-0278-1 datasheet. Its 1500 W peak pulse power rating and 206.3 V clamping voltage enable effective suppression of combination wave surges (1.2/50 µs voltage, 8/20 µs current) commonly used in IEC61000-4-5 testing. The JANS1N6170US/TR's hermetic seal and Category 1 bonds further ensure consistent performance under repeated surge stress.
What is the thermal resistance specification for JANS1N6170US/TR?
The JANS1N6170US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, measured under standard conditions. This parameter reflects the device's ability to conduct heat from the silicon junction to the end-cap terminals, which interface directly with PCB copper. For thermal design, this value enables accurate calculation of junction temperature rise during repetitive pulse operation, especially critical in high-ambient environments like engine compartments where the JANS1N6170US/TR is deployed.
How does the JANS1N6170US/TR differ from commercial-grade 1N6170AUS?
The JANS1N6170US/TR differs from commercial-grade 1N6170AUS in three key ways: it is fully qualified to MIL-PRF-19500/516 Level JANS (including radiation hardness verification per MicroNote 050), uses Category 1 metallurgical bonds for mechanical robustness, and undergoes rigorous screening for space and nuclear applications. The 1N6170AUS shares identical electrical parameters but lacks military qualification, making the JANS1N6170US/TR the only choice for flight-certified systems where the JANS1N6170US/TR's proven reliability is mandatory.
