Product details
Overview
JANTX1N6148US/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTX reliability level. It provides 13.7 V working standoff voltage (VWM), 17.10 V minimum breakdown voltage (V(BR)) at 65 mA, and clamps transients to 25.1 V at 59.8 A peak pulse current (IPP) for 10/1000 µs waveform - deployed in avionics power rail protection.
For engineers reviewing the JANTX1N6148US/TR datasheet, JANTX1N6148US/TR pinout, JANTX1N6148US/TR application, or JANTX1N6148US/TR equivalent, key selection criteria include its 1500 W peak pulse power rating, -55 °C to +175 °C junction temperature range, Category 1 metallurgical bonds, RoHS-compliant tin/lead terminations (non-RoHS version), and SQ-MELF "C" package compatibility with automated placement.
Technical Context
This TVS operates bidirectionally with no polarity marking and delivers robust ESD/EFT protection per IEC61000-4-2 and IEC61000-4-4, plus lightning-induced surge suppression per select IEC61000-4-5 levels. Its hard-glass construction and internal tungsten slugs enable stable performance under thermal cycling and radiation exposure.
Rated for 1500 W peak pulse power at 25 °C (10/1000 µs), it derates linearly above 150 °C case temperature to zero at 175 °C. Thermal resistance from junction to end cap is 5.0 °C/W, supporting high-reliability mounting on thermally managed PCBs with controlled copper pour.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.7 V - maximum continuous reverse/forward voltage before conduction begins; defines safe operating margin below clamping threshold. |
| V(BR) min | 17.10 V @ 65 mA - guaranteed minimum breakdown voltage ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 25.1 V @ 59.8 A - clamping voltage limits downstream circuit stress during 10/1000 µs transients. |
| PPP | 1500 W - peak pulse power handling capacity for short-duration surges without failure. |
| TJ Range | -55 °C to +175 °C - enables deployment in extreme environments including aerospace and downhole systems. |
| RθJEC | 5.0 °C/W - low thermal resistance supports reliable heat dissipation through end-cap solder joints. |
| αV(BR) | 0.085 %/°C - low temperature coefficient maintains stable breakdown voltage across operational temperature range. |
Pinout & Package
Package: SQ-MELF "C" (hermetically sealed voidless hard glass with tungsten slugs); terminals are tin/lead plated copper; no polarity marking; weight ≈ 1100 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | Identical terminal behavior in both directions; symmetric clamping enables placement without orientation constraints. |
| End Cap (both ends) | Thermal and electrical interface | Primary heat transfer path to PCB; also serves as current return path during clamping event. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional transient suppression | Enables single-device protection of AC-coupled or floating signal/power lines without polarity concerns. |
| Category 1 metallurgical bonds | Ensures mechanical integrity and low-resistance interconnects under shock, vibration, and thermal cycling. |
| Voidless hermetic seal | Prevents moisture ingress and long-term parameter drift in humid or corrosive environments. |
| MIL-PRF-19500/516 JANTX qualification | Validated reliability for mission-critical systems requiring zero-tolerance failure modes. |
| IEC61000-4-2/4-4/4-5 compliance | Meets international immunity standards for ESD, fast transient bursts, and lightning-induced surges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6148US | Higher reliability screening (JANTXV level), tighter parametric tolerances, and extended burn-in per MIL-PRF-19500/516. | Suitable for space-grade systems requiring enhanced lot traceability and radiation testing documentation. | Select when full JANTXV qualification and test reports are mandated by program requirements. |
| 1N6148AUS | Commercial-grade version; same electrical specs but no military qualification, no radiation hardness claim, and RoHS-compliant matte-tin terminations available. | Applicable in industrial or telecom infrastructure where cost sensitivity outweighs extreme environment demands. | Choose for non-military programs needing identical clamping performance without MIL-spec overhead. |
Compared with JANTX1N6148US/TR, JANTXV1N6148US adds screening rigor and documentation for space-critical use, while 1N6148AUS removes military qualification to reduce cost and enable RoHS compliance - all share identical VWM, VC, and PPP values.

FAQ
What is the clamping voltage of JANTX1N6148US/TR at its rated peak pulse current?
The JANTX1N6148US/TR has a maximum clamping voltage (VC) of 25.1 V when subjected to its rated peak pulse current (IPP) of 59.8 A under the standard 10/1000 µs waveform. This value is measured per MIL-PRF-19500/516 test conditions and guarantees consistent overvoltage limiting performance across qualified lots.
Is JANTX1N6148US/TR compatible with lead-free reflow processes?
JANTX1N6148US/TR uses tin/lead plated terminations and is rated for a maximum solder temperature of 260 °C for 10 seconds. While it supports standard SnPb reflow profiles, it is not RoHS-compliant; for lead-free assembly, the commercial-grade 1N6148AUS with matte-tin finish should be selected instead.
Does JANTX1N6148US/TR require orientation during PCB placement?
No - JANTX1N6148US/TR is a bidirectional TVS with no polarity marking and symmetric electrical characteristics. Its SQ-MELF "C" package allows placement in either orientation without affecting clamping behavior or circuit protection function.
What is the maximum steady-state power dissipation of JANTX1N6148US/TR at 25 °C ambient?
At TA = 25 °C, the JANTX1N6148US/TR has a steady-state power dissipation rating of 3.0 W. This value assumes adequate PCB thermal management; derating applies above 25 °C per Figure 4 in the datasheet, reaching zero at 150 °C case temperature.
How does JANTX1N6148US/TR meet IEC61000-4-5 surge immunity requirements?
JANTX1N6148US/TR suppresses lightning-induced surges per select levels of IEC61000-4-5 due to its 1500 W peak pulse power rating and 25.1 V clamping voltage, which limit induced voltages on protected lines to safe thresholds for downstream ICs. Its hard-glass construction ensures repeatable performance across multiple surge events.
