Product details
Overview
JANTX1N6169US/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), 98.8 V working standoff voltage (VWM), and 178.8 V clamping voltage (VC) at 8.4 A peak pulse current - deployed in avionics power rail protection and MIL-STD-461E transient-hardened interfaces.
For engineers reviewing the JANTX1N6169US/TR datasheet, JANTX1N6169US/TR pinout, JANTX1N6169US/TR application, or JANTX1N6169US/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JANTX qualification, Category 1 metallurgical bonds, -55°C to +175°C operating junction temperature, RoHS-compliant tin/lead termination (non-RoHS per standard), and absence of polarity marking due to bidirectional symmetry.
Technical Context
This device operates as a voltage-clamped, bidirectional surge protector with no intrinsic polarity - relying on symmetrical avalanche breakdown in both directions. Its hard-glass hermetic construction eliminates internal voids and supports radiation hardness per MicroNote 050, while tungsten slugs and Category 1 metallurgical bonds ensure mechanical and thermal robustness under shock, vibration, and thermal cycling.
It delivers 1500 W peak pulse power for 10/1000 µs transients per IEC61000-4-5 Level 3/4, clamps at ≤178.8 V under 8.4 A impulse, and maintains ≤5 µA standby current at 98.8 V standoff - enabling reliable protection of sensitive analog front-ends and digital control lines in high-reliability platforms without DC bias constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 98.8 V - maximum continuous reverse/forward voltage before conduction begins; sets upper limit for protected circuit's normal operating voltage. |
| VC @ IPP | 178.8 V at 8.4 A - clamping voltage during 10/1000 µs surge; defines worst-case overvoltage seen by downstream components. |
| PPP | 1500 W - peak pulse power handling capability; determines survivability against lightning-induced surges and EFT bursts. |
| TJ Range | -55°C to +175°C - qualified junction temperature range; enables deployment in engine bay, radar modules, and space-grade electronics. |
| RθJEC | 5.0 °C/W - thermal resistance from junction to end cap; informs heatsinking requirements when used in high-duty-cycle applications. |
| ID @ VWM | 5 µA - leakage current at rated standoff; ensures negligible loading on high-impedance signal paths or precision reference rails. |

IC Role / Device Role / Timing Role: Low-capacitance (<15 pF typical) bidirectional clamp across differential antenna feed lines prior to balun input. Use Value: Sub-5 µA leakage at 98.8 V VWM avoids gain compression or DC offset in ultra-low-noise amplifier stages. |
| Spacecraft Power Interface | Naval Radar Signal Conditioning |
Use Scenario: Input protection for satellite power management ICs subjected to single-event burnout (SEB) precursors and TID effects in LEO orbit. IC Role / Device Role / Timing Role: Radiation-hardened TVS placed upstream of PMIC enable pins to suppress secondary transients generated by particle strikes. Use Value: Inherent radiation tolerance per MicroNote 050 and -55°C to +175°C operation support unheated payload bays and deep-space thermal profiles. | Use Scenario: Surge suppression on analog sensor inputs (e.g., temperature, pressure) in shipboard radar cooling control systems exposed to salt fog and EMP. IC Role / Device Role / Timing Role: Standoff-rated clamp on 4–20 mA loop inputs interfacing with isolated ADCs in harsh marine environments. Use Value: 98.8 V VWM accommodates 24 V loop supply headroom while 5 µA leakage prevents loop current error beyond ±0.01% FS. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6169AUS | Commercial-grade version; same VWM, VC, and PPP but lacks MIL-PRF-19500/516 screening and JANTX-level traceability. | Approved for non-military industrial use only; not authorized for DoD or NASA programs requiring JANTX certification. | Select only if full military qualification is unnecessary and cost sensitivity outweighs long-term reliability assurance. |
| JANTXV1N6169US | Higher reliability screening level (JANTXV); includes extended burn-in, lot acceptance testing, and tighter parametric limits per MIL-PRF-19500/516. | Required for flight hardware, nuclear command systems, and other Class V mission-critical applications. | Choose when system-level failure risk mandates highest available screening - adds ~25% cost premium over JANTX. |
Compared with JANTX1N6169US/TR, the commercial 1N6169AUS reduces cost but forfeits military traceability and environmental screening, while JANTXV1N6169US enhances burn-in and test rigor for zero-defect mission assurance - making JANTX the optimal balance of certified reliability and program affordability.

FAQ
What is the clamping voltage of JANTX1N6169US/TR under a 10/1000 µs surge?
The JANTX1N6169US/TR has a maximum clamping voltage (VC) of 178.8 V at 8.4 A peak pulse current for a 10/1000 µs waveform. This value is guaranteed per MIL-PRF-19500/516 test conditions and defines the upper voltage limit imposed on protected circuits during standardized surge events. The JANTX1N6169US/TR achieves this performance using symmetric avalanche breakdown in its voidless hard-glass structure.
Is JANTX1N6169US/TR RoHS compliant?
JANTX1N6169US/TR is not RoHS compliant - it uses standard tin/lead termination per MIL-PRF-19500/516 requirements. RoHS-compliant matte-tin versions are available only in commercial-grade variants (e.g., 1N6169AUS). The JANTX1N6169US/TR retains leaded plating to ensure solder joint reliability under thermal cycling and mechanical shock in military deployments.
Does JANTX1N6169US/TR have polarity markings?
No, JANTX1N6169US/TR has no polarity marking because it is a bidirectional TVS device. Its symmetrical construction allows identical clamping behavior in both forward and reverse directions, eliminating the need for orientation-specific placement on PCBs. This feature simplifies assembly and reduces risk of misplacement in high-density layouts where the JANTX1N6169US/TR serves as primary surge protection.
What is the maximum steady-state power dissipation of JANTX1N6169US/TR at 25°C ambient?
The JANTX1N6169US/TR has a maximum steady-state power dissipation (PD) of 3.0 W at TA = 25°C, derating linearly to zero at 150°C case temperature. This rating applies to continuous DC or low-frequency AC stress and assumes adequate PCB copper area for thermal conduction. The JANTX1N6169US/TR is not intended for sustained power regulation - its design focus remains transient suppression, not steady-state dissipation.
How does JANTX1N6169US/TR differ from JANS1N6169US?
JANTX1N6169US/TR is qualified to MIL-PRF-19500/516 at JANTX reliability level, including group A and B testing, while JANS1N6169US meets the higher JANS level with additional group C (life test) and D (qualification) requirements, plus radiation hardness validation. The JANTX1N6169US/TR offers proven reliability for most flight and ground systems, whereas JANS is reserved for nuclear-hardened or deep-space applications where total ionizing dose (TID) tolerance exceeds 100 krad(Si).
