Product details
Overview
JANS1N6163US/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 56.0 V working standoff voltage (VWM), 71.3 V minimum breakdown voltage (V(BR)) at 20 mA, 103.1 V clamping voltage (VC) at 14.5 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 JANS1N6163US/TR datasheet, JANS1N6163US/TR pinout, JANS1N6163US/TR application, or JANS1N6163US/TR equivalent, this part delivers military-grade transient suppression with Category 1 metallurgical bonds, triple-layer passivation, and -55°C to +175°C junction temperature operation - critical for launch vehicle power conditioning and satellite bus interfaces.
Technical Context
This TVS operates bidirectionally with no polarity marking and is designed for hard-switching DC power rails where lightning-induced surges (IEC61000-4-5 Level 3/4), ESD (IEC61000-4-2 ±15 kV air), and EFT (IEC61000-4-4 ±2 kV) must be clamped without failure. Its glass-encapsulated tungsten-slug construction ensures zero voids and stable thermal resistance (RθJEC = 5.0°C/W).
The device uses internal Category 1 metallurgical bonds and exhibits a +0.100%/°C temperature coefficient of breakdown voltage (αV(BR)), enabling predictable clamping behavior across extreme thermal excursions in orbital environments. It is RoHS-compliant only in commercial versions; JANS1N6163US/TR is non-RoHS per MIL-spec requirements.

FAQ
What is the maximum clamping voltage of JANS1N6163US/TR under a 10/1000 µs surge?
The JANS1N6163US/TR has a maximum clamping voltage (VC) of 103.1 V when subjected to its rated peak pulse current of 14.5 A under a 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3019 and is guaranteed across the full -55°C to +175°C junction temperature range. The JANS1N6163US/TR maintains this clamping performance without degradation after repeated surge events, supporting mission-critical power bus protection.
Is JANS1N6163US/TR RoHS compliant?
No, JANS1N6163US/TR is not RoHS compliant. As a JANS-level military-qualified part, it uses tin/lead plating per MIL-PRF-19500/516 requirements and is exempt from RoHS Directive 2011/65/EU Annex III. RoHS-compliant versions (e3 suffix) are available only in commercial-grade variants such as 1N6163AUS, which lack MIL-spec qualification and radiation hardness validation.
What does the "US" suffix indicate in JANS1N6163US/TR?
The "US" suffix in JANS1N6163US/TR denotes the SQ-MELF-style surface-mount "C" package - a voidless hermetically sealed hard-glass case with square end caps optimized for automated placement and conduction cooling. It distinguishes this variant from axial-leaded versions (e.g., JANS1N6163) and confirms compliance with Microsemi's mechanical drawing T4-LDS-0278-1 for military surface-mount TVS devices.
How is JANS1N6163US/TR qualified for space applications?
JANS1N6163US/TR is qualified to MIL-PRF-19500/516 at JANS level, including full lot acceptance testing per MIL-STD-883 (e.g., Method 1015 temperature cycling, Method 1021 burn-in, Method 1020 ESD sensitivity). It is documented in Microsemi MicroNote 050 as inherently radiation-hardened, with TID tolerance exceeding 100 krad(Si) and displacement damage resistance validated for LEO and GEO orbits - making JANS1N6163US/TR suitable for Class S spaceflight hardware.
What is the thermal resistance from junction to end cap for JANS1N6163US/TR?
The thermal resistance from junction to end cap (RθJEC) for JANS1N6163US/TR is 5.0°C/W, measured per MIL-STD-750 Method 1091. This low value enables efficient conduction cooling when mounted directly to a metal chassis or heatsink, supporting up to 3.0 W steady-state power dissipation at end-cap temperatures ≤150°C - critical for sustained operation in sealed avionics enclosures without forced airflow.
