Product details
Overview
JANTXV1N6154US/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 25.1 V working peak standoff voltage (VWM), 31.4 V minimum breakdown voltage (V(BR)) at 40 mA, 45.7 V clamping voltage (VC) at 32.8 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform - deployed in avionics power bus protection.
For engineers reviewing the JANTXV1N6154US/TR datasheet, JANTXV1N6154US/TR pinout, JANTXV1N6154US/TR application, or JANTXV1N6154US/TR equivalent, key selection criteria include military-grade reliability (JANTXV), 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 operates bidirectionally with no polarity marking and uses internal Category 1 metallurgical bonds within a hard-glass hermetic package. Its clamping action begins at V(BR) ≥ 31.4 V and limits transient energy to ≤ 45.7 V at 32.8 A, enabling robust protection of downstream DC-DC converters and interface ICs against fast-rising surges.
Thermal performance is defined by junction-to-end-cap resistance of 5.0 °C/W and derating from 5.0 W off-state power at TEC = 150 °C to zero at 175 °C. Standby leakage remains ≤ 5 µA at 25.1 V VWM, ensuring minimal impact on low-power sensor rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 25.1 V - Maximum continuous reverse/forward voltage before conduction; sets operating margin for 24 V nominal systems. |
| V(BR) min | 31.4 V @ 40 mA - Guaranteed breakdown onset; ensures reliable triggering above system transients but below IC absolute max ratings. |
| VC @ IPP | 45.7 V @ 32.8 A - Clamped voltage during 10/1000 µs surge; defines worst-case stress on protected circuitry. |
| PPP | 1500 W - Peak impulse power handling; supports MIL-STD-461 CS115/116 and IEC61000-4-5 Level 4 surges. |
| ID @ VWM | ≤ 5 µA - Ultra-low leakage at rated standoff; avoids loading of high-impedance bias networks or precision references. |
| TJ range | –55 to +175 °C - Full military temperature operation; validated for engine bay, radar, and space-qualified platforms. |
Pinout & Package
Package: SQ-MELF (C-type) surface-mount glass body with square-end-cap terminals; hermetically sealed voidless construction; tungsten slugs; tin/lead-plated copper terminations; weight ≈ 1100 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Surge current path | No polarity marking - symmetric conduction in either direction; both ends serve as interchangeable surge entry points. |
| End Cap (both ends) | Thermal interface | Direct thermal path to PCB copper; RθJEC = 5.0 °C/W enables efficient heat dissipation during repetitive pulses. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating differential lines without polarity concerns. |
| Category 1 metallurgical bonds | Guarantees bond integrity under thermal cycling and mechanical shock - critical for aerospace vibration environments. |
| Voidless hermetic seal | Prevents moisture ingress and internal corrosion over 20+ year field life in humid or salt-laden deployments. |
| MIL-PRF-19500/516 JANTXV qualification | Validated screening includes burn-in, temperature cycling, and lot acceptance testing per military reliability standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6153US/TR | VWM = 22.8 V, V(BR) min = 28.5 V, VC = 41.6 V @ 36.0 A - lower clamping threshold and higher IPP. | Better suited for 20–24 V systems where tighter clamping margin is required before downstream overvoltage trip points. | Select when protecting 24 V rail logic with <40 V absolute maximum ratings; verify reduced thermal margin due to lower VWM. |
| JANTXV1N6155US/TR | VWM = 27.4 V, V(BR) min = 34.2 V, VC = 49.9 V @ 30.1 A - higher standoff and clamping, lower IPP. | Preferred for 28 V systems with higher transient headroom and less sensitive downstream components. | Choose for legacy 28 V military platforms where existing designs specify 27–30 V standoff; maintains same package and footprint. |
Compared with JANTXV1N6154US/TR, JANTXV1N6153US/TR offers tighter clamping at lower voltage but reduced surge headroom, while JANTXV1N6155US/TR trades clamping precision for broader system voltage tolerance - all share identical SQ-MELF packaging and JANTXV qualification.

FAQ
What is the maximum clamping voltage of JANTXV1N6154US/TR under standard test conditions?
The JANTXV1N6154US/TR has a maximum clamping voltage (VC) of 45.7 V when subjected to a 10/1000 µs surge waveform at its rated peak pulse current of 32.8 A. This value is measured per MIL-STD-883 Method 3012 and is guaranteed across the full –55 °C to +175 °C junction temperature range. The JANTXV1N6154US/TR maintains this clamping performance without degradation after multiple surge events within its specified PPP rating.
Is JANTXV1N6154US/TR suitable for bidirectional signal line protection?
Yes, JANTXV1N6154US/TR is inherently bidirectional and requires no polarity marking - it conducts symmetrically in both directions once V(BR) is exceeded. This makes the JANTXV1N6154US/TR ideal for protecting AC-coupled interfaces like RS-422, LVDS, or isolated CAN transceivers where voltage polarity reverses during normal operation. Its glass-body construction ensures consistent response regardless of surge direction.
Does JANTXV1N6154US/TR meet IEC61000-4-5 surge immunity requirements?
Yes, JANTXV1N6154US/TR is validated for protection against surges per IEC61000-4-5, including combination wave (1.2/50 µs voltage, 8/20 µs current) up to Level 4 (4 kV line-to-earth, 2 kV line-to-line). Its 1500 W peak pulse power rating and 45.7 V clamping voltage enable compliant system-level design when used with appropriate PCB layout and filtering. The JANTXV1N6154US/TR achieves this without external triggering circuitry.
What is the thermal resistance specification for JANTXV1N6154US/TR?
JANTXV1N6154US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, measured from the semiconductor junction to either end cap termination. This parameter governs heat transfer during surge events and supports steady-state power dissipation up to 5.0 W at TEC = 150 °C, derating linearly to zero at 175 °C. The JANTXV1N6154US/TR relies on direct end-cap soldering to large copper areas for optimal thermal performance.
How does JANTXV1N6154US/TR differ from commercial-grade 1N6154AUS?
JANTXV1N6154US/TR is screened to MIL-PRF-19500/516 JANTXV reliability levels - including extended temperature cycling, burn-in, and lot acceptance testing - whereas commercial 1N6154AUS meets only standard JEDEC specifications. The JANTXV1N6154US/TR also features voidless hermetic sealing and Category 1 metallurgical bonds not present in the commercial version. Both share identical electrical parameters, but only JANTXV1N6154US/TR is approved for flight-critical applications.
