Product details
Overview
JANTXV1N6148US/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 13.7 V working standoff voltage (VWM), 25.1 V clamping voltage (VC) at 59.8 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform, used in high-reliability military power rail protection.
For engineers reviewing the JANTXV1N6148US/TR datasheet, JANTXV1N6148US/TR pinout, JANTXV1N6148US/TR application, or JANTXV1N6148US/TR equivalent, key selection factors include its MIL-qualified reliability level, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and compatibility with EIA-481-B tape-and-reel handling.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses internal Category 1 metallurgical bonds within a hard-glass hermetic package. Its breakdown voltage is 17.10 V minimum at 65 mA test current, and it exhibits a temperature coefficient of 0.085 %/°C for V(BR).
The device delivers 1500 W peak pulse power under 10/1000 µs conditions while maintaining 10 µA standby current at VWM and derating linearly above 150 °C junction temperature. It meets IEC61000-4-2 (ESD), -4-4 (EFT), and select levels of -4-5 (lightning surge) standards.
Key Specifications

| VWM | 13.7 V - maximum continuous reverse/forward voltage before conduction begins |
| V(BR) min | 17.10 V @ 65 mA - guaranteed minimum breakdown threshold under specified test current |
| VC @ IPP | 25.1 V @ 59.8 A - clamped voltage during 10/1000 µs surge, defining worst-case rail excursion |
| PPP | 1500 W - peak transient energy absorption capability for standardized surge waveform |
| TJ range | –55 to +175 °C - operational junction temperature span supporting extended military environments |
| RθJEC | 5.0 °C/W - thermal resistance from junction to end cap, critical for power dissipation design |

Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6148US/TR | Commercial-grade version; same electrical specs but not MIL-qualified; RoHS-compliant matte-tin plating available | Lacks JANTXV screening; unsuitable for programs requiring MIL-PRF-19500 conformance | Select when cost-sensitive commercial designs require identical clamping performance without military screening |
| JANTXV1N6147US/TR | Lower VWM (12.2 V), lower VC (22.3 V), higher IPP (67.3 A); otherwise identical package and qualification | Better suited for 12 V nominal systems where tighter clamping margin is required | Choose for 12 V rail protection where lower clamping voltage improves system fault margin |
Compared with JANTXV1N6148US/TR, the commercial 1N6148US/TR offers identical electrical performance without military screening, while JANTXV1N6147US/TR provides tighter clamping for 12 V systems-both require review of VWM/VC alignment with protected circuit tolerances.

FAQ
What is the clamping voltage of JANTXV1N6148US/TR under standard surge conditions?
JANTXV1N6148US/TR has a maximum clamping voltage (VC) of 25.1 V when subjected to its rated 59.8 A peak pulse current (IPP) under the 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3013 and defines the upper voltage limit seen by downstream circuitry during surge events. The JANTXV1N6148US/TR maintains this clamping performance across its full operating temperature range.
Is JANTXV1N6148US/TR suitable for bidirectional signal line protection?
JANTXV1N6148US/TR is designed as a bidirectional TVS and can protect AC-coupled or differential signal paths where transients may occur in either polarity. However, its 13.7 V working standoff voltage makes it best suited for power rail protection rather than low-voltage data lines. For signal integrity, verify that 25.1 V clamping does not exceed absolute maximum ratings of protected ICs when used on JANTXV1N6148US/TR-protected interfaces.
Does JANTXV1N6148US/TR require special PCB layout considerations?
Yes. JANTXV1N6148US/TR relies on end-cap thermal conduction, so its PCB footprint must follow Microsemi's recommended pad layout in T4-LDS-0278-1: minimum 0.090" center adhesive spot (optional), controlled copper area for thermal mass, and clearance from adjacent components. Thermal resistance drops significantly with proper copper pour; inadequate layout risks exceeding 175 °C junction temperature during repeated surges.
How does the JANTXV qualification level affect the reliability of JANTXV1N6148US/TR?
JANTXV qualification subjects JANTXV1N6148US/TR to enhanced screening per MIL-PRF-19500/516, including extended burn-in, temperature cycling, and lot acceptance testing beyond standard JAN requirements. This results in demonstrated failure rates below 100 FIT for high-reliability applications. The JANTXV1N6148US/TR qualification is documented in Microsemi's QPL listing and supports DoD acquisition compliance.
Can JANTXV1N6148US/TR be used in RoHS-compliant assemblies?
JANTXV1N6148US/TR uses traditional tin/lead plating and is not RoHS compliant. Microsemi offers RoHS-compliant versions only for commercial-grade parts (e.g., 1N6148AUS/TR with e3 suffix). For programs requiring RoHS compliance, JANTXV1N6148US/TR must be replaced with a qualified alternative or approved under exemption; no lead-free variant exists for the JANTXV level.
