Product details
Overview
JANTXV1N6159US/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTXV level. It provides 38.8 V working peak standoff voltage (VWM), 70.1 V clamping voltage (VC) at 21.4 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform - deployed in avionics power rail protection.
For engineers reviewing the JANTXV1N6159US/TR datasheet, JANTXV1N6159US/TR pinout, JANTXV1N6159US/TR application, or JANTXV1N6159US/TR equivalent, key selection criteria include military-grade reliability, bidirectional surge suppression capability, hermetic glass package integrity, and compliance with IEC61000-4-2/4-4/4-5 transient immunity standards.
Technical Context
This TVS operates bidirectionally without polarity marking and uses internal Category 1 metallurgical bonds within a hard-glass, voidless hermetic enclosure. Its breakdown voltage is 48.5 V minimum at 25 mA test current, with ±5% tolerance on VC and V(BR) for the "A" suffix variant.
Thermal resistance junction-to-end cap is 5.0 °C/W, enabling stable operation up to +175 °C junction temperature. Standby current is limited to 5 µA at VWM, and it supports ESD immunity per MIL-STD-750 Method 1020 without external sensitivity mitigation.
Key Specifications

| VWM | 38.8 V - maximum continuous reverse standoff voltage before conduction begins |
| V(BR) min | 48.5 V @ 25 mA - guaranteed minimum breakdown threshold under specified test current |
| VC @ IPP | 70.1 V @ 21.4 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPP | 1500 W - peak impulse power handling for transient suppression without failure |
| ID @ VWM | 5 µA - leakage current at rated standoff, minimizing standby power loss |
| αV(BR) | 0.095 %/°C - temperature coefficient defining V(BR) drift over operating range |
| TJ Range | −55 to +175 °C - full military temperature range for deployment in harsh environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6159AUS | Commercial-grade version; same electrical specs but no MIL-PRF-19500/516 qualification or JANTXV screening | Lacks burn-in, temperature cycling, and lot traceability required for defense programs | Select when cost-sensitive commercial aerospace or industrial designs accept reduced reliability assurance |
| JANTXV1N6158US/TR | Lower VWM (35.8 V) and VC (64.6 V); 23.2 A IPP - 3.0 V lower clamping headroom | Better suited for 24 V systems with tighter voltage margins; less margin for 28 V bus overshoot | Choose where lower clamping voltage is prioritized over 28 V bus compatibility |
Compared with JANTXV1N6159US/TR, 1N6159AUS offers identical electrical performance without military screening, while JANTXV1N6158US/TR trades 3.0 V higher clamping headroom for tighter 24 V system fit - making JANTXV1N6159US/TR optimal for 28 V avionics with margin-critical protection.

FAQ
What is the clamping voltage of JANTXV1N6159US/TR at its rated peak pulse current?
JANTXV1N6159US/TR has a maximum clamping voltage (VC) of 70.1 V at 21.4 A peak pulse current (IPP) for a 10/1000 µs waveform. This value is measured under standardized surge conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The clamping performance is guaranteed across the full −55 to +175 °C junction temperature range, and JANTXV1N6159US/TR maintains this specification after MIL-PRF-19500/516 JANTXV-level environmental screening.
Is JANTXV1N6159US/TR RoHS compliant?
No, JANTXV1N6159US/TR is not RoHS compliant. Per the manufacturer's documentation, RoHS-compliant versions (marked with e3 suffix) are available only for commercial-grade variants such as 1N6159AUS. The JANTXV1N6159US/TR uses tin/lead plating on copper terminals and is manufactured to meet MIL-PRF-19500/516 requirements, which permit leaded finishes for enhanced solder joint reliability in high-reliability applications.
What does the "JANTXV" prefix indicate for JANTXV1N6159US/TR?
"JANTXV" denotes the highest reliability screening level under MIL-PRF-19500/516, including extended burn-in, temperature cycling, mechanical shock, and lot acceptance testing. For JANTXV1N6159US/TR, this means guaranteed operation from −55 to +175 °C, traceable lot history, and qualification for use in space, aviation, and nuclear command systems where failure is not an option. It exceeds standard JAN and JANTX levels in both test severity and documentation rigor.
Can JANTXV1N6159US/TR be used in bidirectional AC signal paths?
Yes, JANTXV1N6159US/TR is inherently bidirectional and requires no polarity marking, making it suitable for AC-coupled signal lines, transformer-isolated interfaces, and differential bus protection. Its symmetrical IV curve ensures identical clamping behavior in both directions, with 38.8 V standoff and 70.1 V clamping regardless of voltage polarity. This characteristic is confirmed in the device's nomenclature section and electrical characteristics table, and JANTXV1N6159US/TR is routinely applied in MIL-STD-1553 and RS-422 receiver input protection.
What is the thermal resistance specification for JANTXV1N6159US/TR?
JANTXV1N6159US/TR has a thermal resistance junction-to-end cap (RθJEC) of 5.0 °C/W. This parameter defines how effectively heat generated during surge events transfers from the silicon junction to the end-cap mounting surface. It enables accurate thermal modeling for PCB layout - especially critical when multiple devices share a common heatsink or when operating near maximum ambient temperatures. The value is measured per MIL-STD-750 Method 1022 and applies to the SQ-MELF package configuration used by JANTXV1N6159US/TR.
