Product details
Overview
JANS1N6162US/TR from Microsemi is a hermetically sealed, voidless, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANS level for space-grade reliability. It features a 51.7 V working standoff voltage (VWM), 64.6 V minimum breakdown voltage (V(BR)) at 20 mA, 97.1 V clamping voltage (VC) at 15.4 A peak pulse current (IPP), and 1500 W peak pulse power (10/1000 µs). It is used in radiation-hardened avionics power bus protection.
For engineers reviewing the JANS1N6162US/TR datasheet, JANS1N6162US/TR pinout, JANS1N6162US/TR application, or JANS1N6162US/TR equivalent, key selection criteria include its JANS-level military qualification, bidirectional clamping behavior, 1500 W surge rating, -55°C to +175°C operating range, and SQ-MELF "C" package compatibility with high-reliability PCB assembly.
Technical Context
This TVS operates as a bidirectional voltage-clamping device with no polarity marking, relying on symmetrical avalanche breakdown in both directions. Its hard-glass hermetic construction uses Category 1 metallurgical bonds and triple-layer passivation to ensure robustness against ESD (IEC61000-4-2), EFT (IEC61000-4-4), and lightning-induced surges (IEC61000-4-5).
Thermal performance is defined by a 5.0 °C/W junction-to-end-cap thermal resistance (RθJEC) and linear derating of off-state power above 150 °C end-cap temperature. The device is non-sensitive to ESD per MIL-STD-750 Method 1020 and inherently radiation-hardened per MicroNote 050.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 51.7 V - Maximum continuous reverse/forward voltage before conduction begins; sets system operating margin below clamping threshold. |
| V(BR) min | 64.6 V @ 20 mA - Minimum voltage at which avalanche breakdown initiates; defines turn-on consistency under transient stress. |
| VC @ IPP | 97.1 V @ 15.4 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected downstream circuitry. |
| PPP | 1500 W - Peak pulse power handling capability; enables protection against high-energy transients like lightning-induced surges. |
| TJ/TSTG | -55°C to +175°C - Full military temperature range; supports operation in extreme environments including spacecraft and jet engine bays. |
| αV(BR) | 0.100 %/°C - Temperature coefficient of breakdown voltage; ensures predictable V(BR) drift over wide thermal excursions. |
Pinout & Package
Package: SQ-MELF "C" (hermetically sealed voidless hard glass with tungsten slugs); terminals are tin/lead plated copper; no polarity marking; weight ≈1100 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Common terminal pair | Identical electrical behavior in either direction; no anode/cathode distinction required in layout or schematic symbol. |
| End Cap (both ends) | Thermal and electrical interface | Serves as primary heat path (RθJEC = 5.0 °C/W) and current return path; requires full-surface solder contact for thermal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal/power lines without polarity concerns. |
| JANS qualification per MIL-PRF-19500/516 | Guarantees screening, testing, and traceability for spaceflight and nuclear-hardened systems. |
| Voidless hermetic glass seal | Eliminates moisture ingress and internal delamination risks over decades of field operation in vacuum or humid environments. |
| Category 1 metallurgical bonds | Ensures mechanical and thermal stability under severe shock, vibration, and thermal cycling (e.g., launch and re-entry). |
Applications
| Aerospace Power Distribution | Rad-Hard Avionics Bus Protection |
|---|---|
Use Scenario: Protecting 28 V DC main bus in satellite power management units from load dump and switching transients. IC Role / Device Role / Timing Role: Bidirectional TVS clamping element placed across bus rails to limit voltage excursions to <97.1 V during 1500 W surges. Use Value: Prevents latch-up or burnout in downstream DC-DC converters and telemetry interfaces under MIL-STD-1275E conditions. | Use Scenario: Shielding FPGA I/O banks and ADC reference inputs in radiation-tolerant flight computers. IC Role / Device Role / Timing Role: Standoff-limited transient suppressor mounted directly at connector entry points to shunt ESD/EFT energy before it couples into sensitive logic. Use Value: Maintains signal integrity and prevents bit flips during ground handling and in-orbit particle events due to inherent radiation hardness. |
| Military Vehicle ECUs | Nuclear Instrumentation Systems |
Use Scenario: Safeguarding CAN bus physical layer transceivers in armored vehicle control modules exposed to ignition noise and EMP. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp on differential bus lines, leveraging symmetric V(BR) to preserve common-mode rejection. Use Value: Sustains >100,000 surge cycles without parameter shift-critical for mission-critical vehicle subsystems with no field service access. | Use Scenario: Protecting analog front-ends of neutron/gamma detectors in reactor monitoring systems. IC Role / Device Role / Timing Role: High-temperature-stable TVS on sensor bias rails operating continuously at 150 °C ambient inside containment vessels. Use Value: Delivers guaranteed clamping performance up to +175 °C junction temperature without derating loss-enabling simplified thermal design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6162US | Same electrical specs but qualified to JANTXV level (lower screening rigor than JANS); no radiation hardness documentation provided. | Approved for airborne platforms where full space-grade qualification is not mandated. | Select when cost and lead time are prioritized over TID/radiation assurance. |
| 1N6162AUS | Commercial-grade version; identical VWM/V(BR)/VC/IPP but lacks MIL-PRF-19500/516 qualification and radiation hardening. | Limited to ground-based test equipment or non-safety-critical industrial controls. | Choose only for prototyping or non-mission-critical deployments with full lifecycle traceability waived. |

FAQ
What does the "JANS" prefix indicate for JANS1N6162US/TR?
The "JANS" prefix certifies that JANS1N6162US/TR is qualified to MIL-PRF-19500/516 at the highest reliability level for space applications. This includes rigorous screening for radiation tolerance (per MicroNote 050), extended temperature operation (-55°C to +175°C), and full traceability of materials and processes-distinct from JAN, JANTX, or JANTXV variants.
Is JANS1N6162US/TR unidirectional or bidirectional, and how does that affect circuit placement?
JANS1N6162US/TR is a bidirectional TVS with no polarity marking. It clamps voltage transients equally in both directions, allowing placement across any two nodes-such as power/ground, differential signal pairs, or floating buses-without orientation constraints. This simplifies layout and eliminates risk of reverse installation.
What is the thermal resistance and mounting requirement for JANS1N6162US/TR?
JANS1N6162US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W. Effective heat dissipation requires full-surface solder contact on both end caps to the PCB copper; adhesive-only mounting is not sufficient. Pad layout must follow Microsemi's recommended dimensions (0.205" × 0.310") for mechanical and thermal reliability.
Does JANS1N6162US/TR comply with IEC61000-4-2 and IEC61000-4-5 standards?
Yes-JANS1N6162US/TR provides ESD protection per IEC61000-4-2 and surge immunity per IEC61000-4-5 (select levels), as confirmed in the official datasheet. Its 1500 W peak pulse power (10/1000 µs) and 97.1 V clamping voltage enable compliance with Level 4 ESD (±15 kV air, ±8 kV contact) and Class 3/4 surge waveforms in hardened systems.
Can JANS1N6162US/TR replace commercial 1N6162AUS in existing designs?
JANS1N6162US/TR shares identical electrical parameters (VWM = 51.7 V, V(BR) = 64.6 V, VC = 97.1 V) with 1N6162AUS but adds JANS-level screening, radiation hardness, and hermetic reliability. Physical form factor and soldering profile are identical; however, redesign validation is required for flight use due to differences in qualification scope and traceability-not just drop-in substitution.
