Product details
Overview
JANTX1N6170US/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) at 7.3 A peak pulse current. It operates from −55 °C to +175 °C and is used in high-reliability aerospace power rail protection.
For engineers reviewing the JANTX1N6170US/TR datasheet, JANTX1N6170US/TR pinout, JANTX1N6170US/TR application, or JANTX1N6170US/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANTX qualification, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and IEC61000-4-5 lightning surge compliance.
Technical Context
This TVS diode employs hard-glass construction with internal Category 1 metallurgical bonds to ensure robustness under repeated high-energy transients. Its bidirectional architecture provides symmetrical clamping without polarity sensitivity, enabling direct placement across unidirectional or AC-coupled signal/power lines.
The device delivers 1500 W peak pulse power at 10/1000 µs waveform while maintaining a low thermal resistance of 5.0 °C/W from junction to end cap. Its 0.105 %/°C temperature coefficient of breakdown voltage ensures stable clamping performance across the full −55 °C to +175 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 114.0 V - Maximum continuous DC or repetitive peak voltage the device blocks without conduction. |
| VC @ IPP | 206.3 V at 7.3 A - Clamped voltage during 10/1000 µs surge, defining worst-case overvoltage seen by protected circuitry. |
| PPP | 1500 W - Peak transient energy absorption capability, critical for lightning-induced secondary surges per IEC61000-4-5. |
| TJ/TSTG | −55 °C to +175 °C - Full military-grade temperature range supporting operation in avionics and space-qualified electronics. |
| RθJEC | 5.0 °C/W - Junction-to-end-cap thermal resistance, enabling accurate derating when mounted to heat-sinked metal substrates. |
| αV(BR) | 0.105 %/°C - Temperature coefficient of breakdown voltage, ensuring predictable VBR drift across extreme ambient conditions. |
Pinout & Package
Package: SQ-MELF (square-end-cap metal-encapsulated glass), hermetically sealed voidless hard-glass case with tungsten slugs and tin/lead-plated copper terminals. No polarity marking due to bidirectional functionality.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | Both terminals function identically; no DC polarity-enables symmetric placement across differential lines or AC rails. |
| End Cap (metal slug) | Thermal interface | Primary heat dissipation path; requires direct thermal contact to PCB copper pour or heatsink for sustained power handling. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals or floating DC buses without orientation constraints. |
| Category 1 metallurgical bonds | Ensures mechanical integrity and bond reliability under thermal cycling and shock/vibration in flight systems. |
| Voidless hermetic glass seal | Prevents moisture ingress and long-term parameter drift-critical for 20+ year mission lifetimes. |
| MIL-PRF-19500/516 JANTX qualification | Validates screening, testing, and traceability to meet DoD procurement requirements for Class H reliability. |
Applications
| Aerospace Power Distribution | Avionics Sensor Interface |
|---|---|
Use Scenario: Protection of 115 VAC aircraft bus feeders against lightning-induced transients per DO-160 Section 22. IC Role / Device Role / Timing Role: Bidirectional TVS placed across line-to-line and line-to-ground to clamp induced surges before they reach upstream converters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6169US/TR | VWM = 98.8 V, VC = 178.8 V @ 8.4 A, PPP = 1500 W | Lower clamping voltage suits 100 V nominal systems with tighter overvoltage margins. | Select when system maximum transient voltage must remain below 180 V under worst-case 10/1000 µs surge. |
| JANTX1N6171US/TR | VWM = 121.6 V, VC = 218.4 V @ 6.9 A, PPP = 1500 W | Higher standoff supports 125 VDC distribution busses; slightly reduced IPP. | Choose for 120 V nominal systems requiring higher continuous voltage margin before clamping onset. |
Compared with JANTX1N6170US/TR, JANTX1N6169US/TR offers lower clamping but reduced standoff, while JANTX1N6171US/TR extends voltage margin at the cost of 0.4 A lower peak current handling-both retain identical SQ-MELF packaging and MIL-PRF-19500/516 JANTX qualification.

FAQ
What is the clamping voltage of JANTX1N6170US/TR at its rated peak pulse current?
The JANTX1N6170US/TR has a maximum clamping voltage (VC) of 206.3 V when subjected to its rated 7.3 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is measured per MIL-PRF-19500/516 test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The JANTX1N6170US/TR maintains this clamping performance across its full operational temperature range.
Is JANTX1N6170US/TR RoHS compliant?
No, JANTX1N6170US/TR is not RoHS compliant. Per the manufacturer's nomenclature and datasheet, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants-not for JAN, JANTX, JANTXV, or JANS qualified parts like JANTX1N6170US/TR. This part uses traditional tin/lead plating on copper terminals to meet MIL-PRF-19500/516 solderability and reliability requirements.
What does the "JANTX" prefix indicate for JANTX1N6170US/TR?
Can JANTX1N6170US/TR be used in place of JANTX1N6170US without the "/TR" suffix?
Yes, JANTX1N6170US/TR is functionally identical to JANTX1N6170US-the "/TR" suffix indicates tape-and-reel packaging per EIA-481-B, while the base part number denotes the same electrical and mechanical specifications. Both share identical VWM, VC, PPP, thermal ratings, and MIL-PRF-19500/516 qualification. The JANTX1N6170US/TR variant is optimized for automated SMT placement, whereas the non-TR version may be supplied in bulk or ammo pack.
What is the maximum steady-state power dissipation of JANTX1N6170US/TR at 25 °C ambient?
The maximum steady-state power dissipation (PD) of JANTX1N6170US/TR is 3.0 W at TA = 25 °C, as specified in the Absolute Maximum Ratings table. This rating assumes adequate PCB thermal management; derating is required above 25 °C per the published steady-state derating curve (Figure 5), reaching zero dissipation at 150 °C ambient. The JANTX1N6170US/TR is not intended for continuous power regulation-its design focus is transient suppression.
