Overview
JANS1N6160AUS/TR from Microsemi is a hermetically sealed, voidless, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANS reliability level. It delivers 1500 W peak pulse power (10/1000 µs), 42.6 V working standoff voltage (VWM), 53.2 V minimum breakdown voltage (V(BR)), and clamps to 77.0 V at 19.5 A peak pulse current - deployed in high-reliability military avionics power rail protection.
For engineers reviewing the JANS1N6160AUS/TR datasheet, JANS1N6160AUS/TR pinout, JANS1N6160AUS/TR application, or JANS1N6160AUS/TR equivalent, key selection criteria include its JANS-level qualification, 1500 W surge rating, bidirectional clamping behavior, -55°C to +175°C operating range, and SQ-MELF "C" package compatibility with automated SMT placement.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses hard-glass construction with internal Category 1 metallurgical bonds for radiation hardness and long-term reliability under thermal cycling. Its clamping voltage of 77.0 V at 19.5 A ensures predictable overvoltage limiting during IEC61000-4-5 lightning-induced surges.
The device exhibits a temperature coefficient of breakdown voltage (αV(BR)) of 0.095 %/°C and derates linearly above 150 °C junction temperature, with thermal resistance RθJEC = 5.0 °C/W enabling effective heat transfer to end caps in conduction-cooled layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 42.6 V - maximum continuous DC or repetitive peak reverse voltage before conduction begins; sets upper limit for protected circuit operating voltage. |
| V(BR) min | 53.2 V @ 20 mA - guaranteed minimum breakdown threshold; defines onset of avalanche conduction under controlled test conditions. |
| VC @ IPP | 77.0 V @ 19.5 A - clamping voltage during 10/1000 µs surge; determines worst-case voltage seen by downstream ICs during transient events. |
| PPP | 1500 W - peak pulse power handling capability for standard 10/1000 µs waveform; enables robust protection against lightning and EFT transients. |
| ID @ VWM | 5 µA - leakage current at rated standoff voltage; low enough to avoid loading sensitive bias networks or battery-powered circuits. |
| TJ Range | -55°C to +175°C - full military temperature range supported; validated for operation in harsh environments including aerospace and ground vehicle electronics. |
| RθJEC | 5.0 °C/W - junction-to-end-cap thermal resistance; allows direct thermal path design to heatsinked PCB pads or chassis mounts. |
Pinout & Package
Package: SQ-MELF "C" (hermetically sealed voidless hard glass with tungsten slugs); terminals are tin/lead plated copper; no polarity marking; square-end-cap geometry supports precise pick-and-place alignment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | Either terminal serves as anode or cathode depending on polarity of surge; symmetric clamping enables single-device protection of AC or floating DC lines. |
| End Cap (both ends) | Thermal interface & mechanical anchor | Primary heat dissipation path; requires soldered contact to thermally conductive PCB pads or metal chassis for sustained power handling. |
Key Features

FAQ
What is the maximum clamping voltage of JANS1N6160AUS/TR under a 10/1000 µs surge?
The JANS1N6160AUS/TR clamps to a maximum of 77.0 V when subjected to its rated 19.5 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is measured and guaranteed per Microsemi's T4-LDS-0278-1 specification sheet and defines the upper voltage limit imposed on protected circuitry during surge events.
Is JANS1N6160AUS/TR suitable for space applications?
Yes, JANS1N6160AUS/TR is inherently radiation-hardened per Microsemi MicroNote 050 and qualified to JANS level per MIL-PRF-19500/516, supporting total ionizing dose (TID) tolerance required for low-Earth orbit missions. Its voidless hermetic glass package and Category 1 metallurgical bonds further ensure reliability in vacuum and thermal cycling environments typical of spacecraft.
Does JANS1N6160AUS/TR have polarity markings?
No, JANS1N6160AUS/TR is a bidirectional TVS with no polarity marking - both terminals are functionally identical. This symmetry allows it to protect AC-coupled signals or floating DC rails without orientation constraints during assembly, simplifying layout and reducing risk of misplacement in high-density SMT designs.
What is the thermal resistance from junction to end cap for JANS1N6160AUS/TR?
The thermal resistance from junction to end cap (RθJEC) for JANS1N6160AUS/TR is 5.0 °C/W, as specified in the Absolute Maximum Ratings table. This low value enables efficient heat transfer from the silicon die through the tungsten slugs and glass body to soldered end-cap interfaces - critical for sustaining repeated surge events in conduction-cooled assemblies.
How does the "A" suffix in JANS1N6160AUS/TR affect its electrical parameters?
The "A" suffix in JANS1N6160AUS/TR denotes tighter voltage tolerances: it guarantees minimum breakdown voltage (V(BR)) ≥ 53.2 V, versus non-A versions which have 5% lower minimum V(BR). It also ensures 5% lower clamping voltage (VC) and 5% higher peak pulse current (IPP) compared to non-A variants - delivering more consistent and robust transient response.
