Overview
JANS1N6164US/TR from Microsemi is a hermetically sealed, voidless, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANS reliability level. It features a 62.2 V working peak standoff voltage (VWM), 77.9 V minimum breakdown voltage (V(BR)) at 15 mA, 112.8 V clamping voltage (VC) at 13.3 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform - deployed in high-reliability military avionics power rail protection.
For engineers reviewing the JANS1N6164US/TR datasheet, JANS1N6164US/TR pinout, JANS1N6164US/TR application, or JANS1N6164US/TR equivalent, this part delivers verified ESD/EFT/IEC61000-4-2/4-4/4-5 compliance, radiation-hardened construction per MicroNote 050, and Category 1 metallurgical bonding for mission-critical surge suppression where failure is not tolerable.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses hard-glass encapsulation with tungsten slugs for thermal robustness. Its internal Category 1 metallurgical bonds ensure mechanical integrity under thermal cycling and shock, while triple-layer passivation enhances surface stability in harsh environments.
The device is rated for junction temperatures from –55 °C to +175 °C and exhibits a temperature coefficient of breakdown voltage (αV(BR)) of 0.100 %/°C. Thermal resistance from junction to end cap (RθJEC) is 5.0 °C/W, enabling effective heat dissipation in surface-mount configurations on thermally managed PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 62.2 V - Maximum continuous DC or repetitive peak reverse voltage the device blocks without conduction. |
| V(BR) min | 77.9 V @ 15 mA - Minimum voltage at which the device enters controlled avalanche breakdown under specified test current. |
| VC @ IPP | 112.8 V @ 13.3 A - Clamped voltage during 10/1000 µs transient, limiting downstream circuit stress to safe levels. |
| PPP | 1500 W - Peak impulse power handling capability, defining survivability against lightning-induced surges per IEC61000-4-5. |

FAQ
What is the clamping voltage of JANS1N6164US/TR and how is it measured?
The JANS1N6164US/TR has a maximum clamping voltage (VC) of 112.8 V, measured at a peak pulse current (IPP) of 13.3 A using a standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuits during surge events and is guaranteed across the full qualified temperature range of –55 °C to +175 °C. The JANS1N6164US/TR maintains this clamping performance due to its hard-glass construction and Category 1 metallurgical bonds.
Is JANS1N6164US/TR RoHS compliant?
No, JANS1N6164US/TR is not RoHS compliant. Per the datasheet, RoHS-compliant matte-tin terminations are available only on commercial-grade versions (e.g., 1N6164AUS), not on JANS-qualified parts. The JANS1N6164US/TR uses traditional tin/lead plating to meet MIL-PRF-19500/516 solderability and reliability requirements, including compatibility with legacy military assembly processes.
Does JANS1N6164US/TR have polarity markings?
No, JANS1N6164US/TR does not have polarity markings because it is a bidirectional TVS. Its symmetrical construction allows either terminal to serve as anode or cathode depending on the polarity of the transient event. This eliminates orientation errors during placement and simplifies layout for AC-coupled or floating-rail protection schemes - a key feature confirmed in the "POLARITY" section of the mechanical packaging documentation.
What is the thermal resistance specification for JANS1N6164US/TR?
The JANS1N6164US/TR has a thermal resistance from junction to end cap (RθJEC) of 5.0 °C/W. This parameter is critical for calculating junction temperature rise during repetitive pulse operation and must be used with end-cap thermal interface design (e.g., copper pour area, thermal vias) to ensure TJ stays within the –55 °C to +175 °C rating. The value is measured per MIL-STD-750 Method 1022 and applies to the hermetically sealed glass package with tungsten slugs.
How does JANS1N6164US/TR differ from commercial 1N6164AUS?
JANS1N6164US/TR differs from 1N6164AUS in qualification level, screening, and construction assurance: it is fully qualified to MIL-PRF-19500/516 at JANS level, includes Category 1 metallurgical bond verification, radiation hardness per MicroNote 050, and voidless hermetic sealing with triple-layer passivation. The 1N6164AUS shares identical electrical specs but lacks military screening, traceability, and environmental hardening - making JANS1N6164US/TR mandatory for certified strategic systems.
