Product details
Overview
JAN1N6163AUS/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JAN level. It provides 56.0 V working peak standoff voltage (VWM), 71.3 V minimum breakdown voltage (V(BR)) at 20 mA, and clamps transients to 103.1 V at 14.5 A (10/1000 µs pulse), delivering 1500 W peak pulse power for lightning surge and ESD protection in avionics power rails.
For engineers reviewing the JAN1N6163AUS/TR datasheet, JAN1N6163AUS/TR pinout, JAN1N6163AUS/TR application, or JAN1N6163AUS/TR equivalent, key selection criteria include its military-grade reliability (JAN qualification), hard-glass SQ-MELF package, bidirectional clamping behavior, 103.1 V clamping voltage at rated IPP, and compatibility with IEC61000-4-2/4-4/4-5 transient immunity standards.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses internal Category 1 metallurgical bonds for high-reliability junction integrity. Its voidless hermetic glass construction ensures stable performance across -55 °C to +175 °C junction temperature range and eliminates moisture-induced failure modes common in plastic-packaged suppressors.
The device delivers 1500 W peak pulse power under 10/1000 µs waveform while maintaining 5.0 µA maximum standby current at VWM and 0.100 %/°C temperature coefficient of breakdown voltage - enabling predictable clamping behavior across wide thermal operating envelopes in aerospace and defense systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 56.0 V - Maximum continuous DC or repetitive peak reverse voltage the device blocks without conduction. |
| V(BR) min | 71.3 V @ 20 mA - Minimum voltage at which the device enters controlled avalanche breakdown, defining turn-on threshold. |
| VC @ IPP | 103.1 V @ 14.5 A (10/1000 µs) - Clamped voltage seen by protected circuit during worst-case surge event. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6163US | No "A" suffix → 5% higher VC (108.3 V), 5% lower V(BR) min (67.7 V), 5% lower IPP (13.8 A) | Reduced clamping margin and lower surge current handling; suitable only where tighter VWM tolerance is not required | Select JAN1N6163AUS/TR when guaranteed 71.3 V V(BR) and 103.1 V VC are mandatory for system-level compliance. |
| JANTX1N6163AUS | JANTX qualification level - additional screening beyond JAN (e.g., extended life test, lot acceptance test) | Higher cost and longer lead time; required only for programs specifying JANTX-level procurement | Choose JAN1N6163AUS/TR for standard JAN reliability without JANTX overhead unless contract mandates higher screening. |

FAQ
What is the clamping voltage of JAN1N6163AUS/TR and under what test condition is it specified?
JAN1N6163AUS/TR has a maximum clamping voltage (VC) of 103.1 V, measured at a peak pulse current (IPP) of 14.5 A using the standardized 10/1000 µs double-exponential surge waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is guaranteed per MIL-PRF-19500/516 test requirements.
Is JAN1N6163AUS/TR unidirectional or bidirectional, and how does that affect its circuit placement?
JAN1N6163AUS/TR is a bidirectional TVS with no polarity marking, meaning it conducts symmetrically for both positive and negative transients. This allows placement across any two nodes requiring transient suppression - such as power-to-ground or differential signal lines - without orientation constraints, simplifying layout and reducing BOM count versus unidirectional alternatives.
What does the "A" suffix in JAN1N6163AUS/TR signify compared to JAN1N6163US?
The "A" suffix in JAN1N6163AUS/TR indicates tighter electrical tolerances: it guarantees a minimum breakdown voltage of 71.3 V (vs. 67.7 V for the non-A version), a clamping voltage of 103.1 V (vs. 108.3 V), and a peak pulse current of 14.5 A (vs. 13.8 A). These tighter specs ensure more predictable and robust transient suppression in safety-critical designs.
Does JAN1N6163AUS/TR meet IEC61000-4-5 for lightning surge immunity?
Yes, JAN1N6163AUS/TR is explicitly rated for protection against secondary effects of lightning per select levels of IEC61000-4-5, enabled by its 1500 W peak pulse power rating and 10/1000 µs waveform capability. Its 103.1 V clamping voltage at 14.5 A ensures downstream circuitry remains within safe operating limits during 4 kV or higher combination wave surges.
What is the thermal resistance and maximum junction temperature specification for JAN1N6163AUS/TR?
JAN1N6163AUS/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W and a maximum junction/storage temperature range of -55 °C to +175 °C. This enables direct thermal coupling to the PCB via its end caps and supports operation in extreme environments such as aircraft bays, armored vehicle engine compartments, and space-based electronics.
