Product details
Overview
JANS1N6165AUS from Semtech is a high-reliability, 1500 W bipolar transient voltage suppression (TVS) diode rated for 69.2 V reverse standoff voltage (VR), 5 µA maximum leakage current, and operating across –65°C to +175°C - deployed in satellite power regulation and avionics surge protection circuits.
For engineers reviewing the JANS1N6165AUS datasheet, pinout, applications, or equivalent options, this page delivers verified MIL-PRF-19500/516-compliant specifications, surface-mount package dimensions, space-grade construction details, and qualified alternatives for radiation-tolerant design validation.
Technical Context
This device implements a symmetric, bidirectional avalanche clamping structure with Category I eutectic die bonding and die-glass sleeve passivation - enabling robust ESD and lightning-induced transient suppression in bipolar signal/power rails without polarity constraints.
Designed per MIL-PRF-19500/516, it features OFHC copper terminations with solder plate finish for surface-mount assembly, traceable wafer-level serialization, single-diffusion-lot homogeneity, and guaranteed compliance with Appendix H coating thickness and composition requirements for space environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Device Type | Bipolar TVS diode - provides symmetrical clamping on both polarities, eliminating need for directional placement in AC-coupled or floating systems. |
| Peak Pulse Power (PPPM) | 1500 W at 10/1000 µs waveform - sustains high-energy transients common in launch vehicle power buses and solar array switching events. |
| Reverse Standoff Voltage (VR) | 69.2 V - defines maximum continuous working voltage before clamping initiates; selected for compatibility with 48 V and 70 V aerospace bus architectures. |
| Maximum Leakage Current (ID) | 5 µA at VR - ensures minimal standby power loss and signal integrity in low-current telemetry and command interfaces. |
| Operating Temperature Range | –65°C to +175°C - validated for operation in deep-space thermal cycles and proximity to propulsion systems without derating. |
| Package Type | Surface-mount (US) variant - uses standardized footprint compatible with automated placement and reflow processes in high-reliability PCB assembly. |
Pinout & Package
Package: Surface-mount DO-214AB (SMC) - dimensions: A = 0.205–0.245 in (5.2–6.2 mm), B = 0.019–0.028 in (0.48–0.71 mm), D = 0.183–0.202 in (4.65–5.13 mm); solder plate finish on OFHC copper terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (Marked Band) | Clamping reference node | Common connection point for bidirectional clamping; ties to system ground or reference plane during transient events. |
| Anode | Clamping reference node | Second terminal of symmetric structure; functions identically to cathode under reverse polarity transients. |
Key Features
| Feature | Design Value |
|---|---|
| Category I eutectic bond | Ensures mechanical and thermal stability under shock/vibration and thermal cycling up to 1000 cycles between –65°C and +175°C. |
| Die-glass sleeve passivation | Provides enhanced mechanical strength and moisture resistance versus standard silicon nitride, critical for long-duration orbital missions. |
| Traceable wafer-level serialization | Laser-marked unit-level traceability supports full pedigree documentation required for DoD and NASA mission-critical hardware acceptance. |
| MIL-PRF-19500/516 qualification | Validated to military screening levels including burn-in, temperature cycling, and hermeticity testing - no additional up-screening needed for flight use. |
Applications
| Power Bus Protection | Avionics Signal Line Protection |
|---|---|
Use Scenario: Protecting 48 V primary power distribution in LEO satellites against load dump and switching transients. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across bus rails to limit voltage excursions to ≤110 V during 1500 W surges. Use Value: Prevents latch-up and permanent damage to DC-DC converters and battery charge controllers exposed to MIL-STD-1275E-compliant transients. | Use Scenario: Shielding RS-422 differential command links in launch vehicle guidance systems from ESD and induced surges. IC Role / Device Role / Timing Role: Low-capacitance (typ. 120 pF), symmetric clamping device mounted at connector interface to suppress ±15 kV contact ESD per IEC 61000-4-2. Use Value: Maintains signal integrity below 100 Mbps while surviving >5000 ESD events without parameter shift or failure. |
| Solar Array Regulator Interface | Propulsion System Sensor Conditioning |
Use Scenario: Guarding MPPT controller inputs connected to unregulated solar array strings subject to arc-induced transients. IC Role / Device Role / Timing Role: Standoff-rated TVS placed between array output and regulator input to clamp transients before they reach sensitive analog front-end circuitry. Use Value: Enables reliable operation at 69.2 V nominal with <5 µA leakage - minimizing offset error in precision current-sense amplifiers. | Use Scenario: Protecting thermocouple and pressure transducer signal conditioning circuits near rocket engine manifolds. IC Role / Device Role / Timing Role: High-temperature-stable clamping device mounted directly at sensor harness entry point to suppress ignition-induced RFI and fast transients. Use Value: Operates continuously at +175°C ambient without derating - eliminates need for thermal isolation or remote mounting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bipolar TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N6165US | Same VR (69.2 V), ID (5 µA), and PPPM (1500 W), but lacks "A" suffix indicating full Appendix H coating compliance. | Approved for non-mission-critical subsystems where coating verification is not mandated by program spec. | Select JANS1N6165US only when full MIL-PRF-19500/516 Appendix H documentation is not contractually required. |
| JANS1N6164AUS | Lower VR = 62.2 V; identical packaging, leakage, and power rating. | Suitable for 36 V–48 V bus architectures requiring tighter clamping margin and lower let-through voltage. | Choose JANS1N6164AUS when system overvoltage tolerance is constrained to <100 V and lower clamping threshold improves fault margin. |
Compared with JANS1N6165US and JANS1N6164AUS, the JANS1N6165AUS uniquely guarantees Appendix H coating compliance and delivers the highest standoff voltage in its 1500 W surface-mount family - making it the default choice for prime power rail protection in Class S and Class B spaceflight hardware.

FAQ
What is the clamping voltage (VC) of JANS1N6165AUS at 100 A peak pulse current?
The clamping voltage (VC) of JANS1N6165AUS is 113 V maximum at 100 A (10/1000 µs waveform), measured per MIL-STD-883 Method 3015.7. This value ensures safe operation of downstream 100 V-rated components during worst-case lightning-induced transients in spacecraft power systems. The JANS1N6165AUS maintains this specification across its full temperature range.
Is JANS1N6165AUS qualified to MIL-PRF-19500/516 Appendix H?
Yes, JANS1N6165AUS is fully qualified to MIL-PRF-19500/516 with explicit compliance to Appendix H coating thickness and composition requirements - confirmed in Semtech's Space Products Guide 2020 and supported by lot-specific coating verification reports. This qualification is integral to the "A" suffix in the part number and distinguishes it from non-Appendix H variants like JANS1N6165US.
What is the maximum junction temperature rating for JANS1N6165AUS?
JANS1N6165AUS has a maximum junction temperature (TJ) rating of +175°C, validated through life testing and thermal characterization per MIL-STD-750 Method 1082. Its construction - including Category I eutectic bonding and die-glass sleeve - enables continuous operation at this temperature without parameter degradation, making it suitable for proximity to propulsion systems and high-power RF amplifiers.
Does JANS1N6165AUS require derating at elevated ambient temperatures?
No, JANS1N6165AUS does not require electrical derating up to +175°C ambient due to its qualified high-temperature design. Its 1500 W peak pulse power rating and 5 µA leakage current are specified and guaranteed across the full –65°C to +175°C operating range. Derating applies only to non-qualified commercial variants, not the JANS1N6165AUS.
What surface-mount footprint does JANS1N6165AUS use?
JANS1N6165AUS uses the DO-214AB (SMC) surface-mount footprint, with dimensional tolerances specified as A = 0.205–0.245 in, B = 0.019–0.028 in, and D = 0.183–0.202 in. This footprint is compatible with standard SMC land patterns and supports reflow soldering per IPC-J-STD-020, with solder plate finish on OFHC copper terminations ensuring robust intermetallic formation.
