Product details
Overview
JANTXV1N6155US/TR from Microsemi is a military-qualified, voidless hermetically sealed bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF package, with 27.4 V working standoff voltage (VWM), 34.2 V minimum breakdown voltage (V(BR)), and 49.9 V clamping voltage (VC) at 30.1 A peak pulse current (IPP). It delivers 1500 W peak pulse power for 10/1000 µs transients and operates from −55 °C to +175 °C - deployed in avionics power bus protection and radar front-end surge suppression.
For engineers reviewing the JANTXV1N6155US/TR datasheet, JANTXV1N6155US/TR pinout, JANTXV1N6155US/TR application, or JANTXV1N6155US/TR equivalent, key selection criteria include MIL-PRF-19500/516 JANTXV qualification level, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning-induced surge immunity.
Technical Context
This TVS diode uses hard-glass hermetic construction with internal Category 1 metallurgical bonds to ensure radiation hardness and long-term reliability under thermal cycling and mechanical shock. Its bidirectional architecture provides symmetrical clamping for AC-coupled signal lines and ungrounded power rails without polarity concerns.
The device exhibits a temperature coefficient of breakdown voltage (αV(BR)) of 0.095 %/°C and linearly derates from full 1500 W pulse power at 25 °C to zero at 175 °C junction temperature, with thermal resistance from junction to end cap (RθJEC) fixed at 5.0 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 27.4 V - maximum continuous reverse voltage before conduction begins; defines safe operating margin below clamping threshold. |
| V(BR) min | 34.2 V @ 30 mA - guaranteed minimum breakdown voltage ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 49.9 V @ 30.1 A - clamping voltage limits transient energy delivered to protected circuitry during 10/1000 µs surge. |
| PPP | 1500 W - peak pulse power rating confirms robustness against high-energy lightning-induced surges per IEC61000-4-5. |
| TJ range | −55 °C to +175 °C - extended junction temperature range supports operation in harsh aerospace and defense environments. |
| RθJEC | 5.0 °C/W - low thermal resistance enables efficient heat transfer to PCB pads or heatsinking end caps. |
| ID @ VWM | 5 µA - ultra-low leakage current preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
Pinout & Package
SQ-MELF (Square End Cap Metal Electrode Leadless Face) package: hermetically sealed voidless hard-glass body with tungsten slugs and tin/lead-plated copper terminals; no polarity marking due to bidirectional symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient current path | Either terminal serves as anode or cathode depending on polarity of transient; no DC bias dependency. |
| End Cap (both ends) | Thermal interface & mechanical anchor | Direct thermal path to PCB pad; requires solderable surface area matching 0.205–0.245 inch length and 0.183–0.202 inch diameter. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables protection of AC-coupled interfaces (e.g., RS-485, MIL-STD-1553) without external polarity management. |
| Category 1 metallurgical bonds | Guarantees bond integrity under thermal shock and vibration, meeting MIL-PRF-19500/516 JANTXV reliability requirements. |
| Voidless hermetic seal | Eliminates moisture ingress and internal delamination risk over 20+ year field life in sealed avionics enclosures. |
| Triple-layer passivation | Prevents surface leakage and electrochemical migration under high humidity and salt fog exposure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6155AUS | Same electrical specs but supplied in bulk (non-tape/reel); lacks TR suffix indicating tape-and-reel packaging. | No difference in circuit function; differs only in logistics format for manual vs. automated assembly. | Select JANTXV1N6155US/TR for SMT pick-and-place production; choose JANTXV1N6155AUS for prototyping or low-volume hand-soldering. |
| 1N6155US/TR (commercial grade) | Identical package and electrical parameters but qualified only to commercial standards (not MIL-PRF-19500/516). | Not suitable for programs requiring JANTXV-level screening, burn-in, or radiation hardness documentation. | Use only in non-military industrial applications where cost sensitivity outweighs long-term reliability certification needs. |
Compared with JANTXV1N6155US/TR, JANTXV1N6155AUS offers identical performance in a non-reel format ideal for bench testing, while 1N6155US/TR provides lower-cost commercial-grade protection without military screening - making the JANTXV variant essential for programs demanding traceable lot-level test data and extended temperature validation.

FAQ
What is the clamping voltage of JANTXV1N6155US/TR at its rated peak pulse current?
The JANTXV1N6155US/TR has a maximum clamping voltage (VC) of 49.9 V when subjected to its rated peak pulse current (IPP) of 30.1 A under a 10/1000 µs waveform. This value is measured per MIL-PRF-19500/516 test conditions and guarantees consistent transient suppression performance across all JANTXV-screened lots of the JANTXV1N6155US/TR.
Is JANTXV1N6155US/TR suitable for bidirectional signal line protection?
Yes, JANTXV1N6155US/TR is inherently bidirectional due to its symmetrical avalanche structure and absence of polarity marking. It clamps both positive- and negative-going transients equally, making it ideal for protecting AC-coupled interfaces such as MIL-STD-1553, RS-422, and transformer-isolated Ethernet PHYs without requiring orientation verification during placement.
Does JANTXV1N6155US/TR meet IEC61000-4-5 for lightning surge immunity?
Yes, JANTXV1N6155US/TR is validated for protection against secondary effects of lightning per select levels of IEC61000-4-5, supported by its 1500 W peak pulse power rating and 49.9 V clamping voltage at 30.1 A. The device's hard-glass construction and Category 1 metallurgical bonds ensure sustained performance through repeated surge events required by that standard.
What is the maximum operating temperature for JANTXV1N6155US/TR?
The JANTXV1N6155US/TR supports a junction temperature range of −55 °C to +175 °C, verified per MIL-PRF-19500/516. Its thermal resistance from junction to end cap (RθJEC) is 5.0 °C/W, enabling reliable operation in sealed avionics enclosures and engine bay ECUs where ambient temperatures exceed 125 °C.
How does the "TR" suffix in JANTXV1N6155US/TR affect packaging and assembly?
The "TR" suffix in JANTXV1N6155US/TR indicates tape-and-reel packaging per EIA-481-B standard, optimized for automated SMT placement. This format ensures consistent orientation, controlled feeding, and ESD-safe handling - critical for high-yield manufacturing of defense-grade assemblies using the JANTXV1N6155US/TR.
