Product details
Overview
JANTXV1N6154AUS/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 standoff voltage (VWM), 31.4 V minimum breakdown voltage (V(BR)), and clamps transients to 45.7 V at 32.8 A peak pulse current (IPP) with 1500 W peak pulse power for 10/1000 µs waveform - deployed in avionics power rail protection.
For engineers reviewing the JANTXV1N6154AUS/TR datasheet, JANTXV1N6154AUS/TR pinout, JANTXV1N6154AUS/TR application, or JANTXV1N6154AUS/TR equivalent, this part delivers military-grade surge immunity, ESD/EFT compliance per IEC61000-4-2/4-4, and radiation-hardened reliability for critical aerospace and defense systems where failure is not an option.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses hard-glass construction with internal Category 1 metallurgical bonds for high-reliability junction integrity. Its thermal resistance junction-to-end cap is 5.0 °C/W, enabling stable operation across -55 °C to +175 °C junction temperature range.
The device meets MIL-PRF-19500/516 qualification requirements for JANTXV-level reliability and exhibits 0.095 %/°C temperature coefficient of breakdown voltage (αV(BR)), ensuring predictable clamping behavior under thermal stress in embedded military platforms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 25.1 V maximum continuous standoff voltage - defines highest DC/repetitive peak voltage before conduction begins. |
| V(BR) min | 31.4 V at 40 mA - guaranteed minimum breakdown threshold for reliable overvoltage triggering. |
| VC @ IPP | 45.7 V at 32.8 A - clamping voltage during 10/1000 µs surge, limiting downstream circuit stress. |
| PPP | 1500 W peak pulse power - sustains high-energy transients without failure under standard test conditions. |
| ID @ VWM | 5 µA maximum standby leakage - ensures minimal power loss and signal integrity in quiescent state. |
| TJ Range | -55 °C to +175 °C - supports operation in extreme environmental conditions typical of airborne and space-qualified systems. |
| αV(BR) | 0.095 %/°C - quantifies voltage drift with temperature, critical for precision clamping in wide-temperature deployments. |
Pinout & Package
Package: Hermetically sealed voidless hard-glass "C" (SQ-MELF) surface-mount package with tungsten slugs and tin/lead-plated copper terminals. Dimensions: BD = 0.183–0.202 in (4.65–5.13 mm), BL = 0.205–0.245 in (5.21–6.22 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | No polarity marking - symmetric terminals conduct equally in both directions during overvoltage events. |
| End Cap (glass body contact) | Thermal interface | Direct thermal path to PCB pad; RθJEC = 5.0 °C/W enables effective heat dissipation during surge events. |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic seal | Eliminates internal moisture ingress and interfacial delamination - essential for long-term reliability in humid or vacuum environments. |
| Category 1 metallurgical bonds | Ensures robust die-attach integrity under mechanical shock, vibration, and thermal cycling per MIL-STD-883. |
| Triple-layer passivation | Provides enhanced surface insulation and contamination resistance on the glass junction, reducing leakage and field-induced failure. |
| MIL-PRF-19500/516 JANTXV qualification | Validates performance across screening, life testing, and environmental stress profiles required for flight-critical hardware. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6154CUS/TR | Same electrical specs but non-A suffix: 5% higher clamping voltage (VC), 5% lower min V(BR), 5% lower IPP. | Less precise clamping margin; suitable only where tighter V(BR) tolerance is not required. | Select JANTXV1N6154AUS/TR when design requires guaranteed 31.4 V minimum breakdown and 45.7 V clamping. |
| JANTXV1N6153AUS/TR | Lower VWM (22.8 V), V(BR) min (28.5 V), and VC (41.6 V); same 1500 W PPP rating. | Better suited for 24 V nominal systems requiring tighter clamping headroom below 42 V. | Choose JANTXV1N6153AUS/TR for 24 V rail protection; retain JANTXV1N6154AUS/TR for 28 V systems needing ≥25.1 V standoff. |
Compared with JANTXV1N6154CUS/TR and JANTXV1N6153AUS/TR, the JANTXV1N6154AUS/TR offers the optimal balance of 25.1 V standoff, 31.4 V breakdown assurance, and 45.7 V clamping for 28 V avionics buses - making it the preferred choice where precise voltage margins and MIL-qualified reliability are jointly required.

FAQ
What is the clamping voltage of JANTXV1N6154AUS/TR at its rated peak pulse current?
The JANTXV1N6154AUS/TR has a maximum clamping voltage (VC) of 45.7 V when subjected to its rated 32.8 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is measured per MIL-PRF-19500/516 test conditions and guarantees that downstream circuitry remains within safe operating limits during surge events. The JANTXV1N6154AUS/TR maintains this clamping performance across its full -55 °C to +175 °C junction temperature range.
Is JANTXV1N6154AUS/TR RoHS compliant?
No, JANTXV1N6154AUS/TR is not RoHS compliant. Per the manufacturer's documentation, RoHS-compliant versions (marked with e3 suffix) are available only for commercial-grade variants of this family. The JANTXV1N6154AUS/TR uses tin/lead plating on copper terminals and is manufactured to meet MIL-PRF-19500/516 requirements, which permit leaded finishes for high-reliability applications. The JANTXV1N6154AUS/TR is intended for use in environments where military specifications supersede RoHS restrictions.
How does the "A" suffix in JANTXV1N6154AUS/TR affect its electrical parameters?
The "A" suffix in JANTXV1N6154AUS/TR indicates tighter voltage tolerances: it guarantees a minimum breakdown voltage of 31.4 V (vs. 5% lower for non-A parts), a maximum clamping voltage of 45.7 V (vs. 5% higher), and a higher rated peak pulse current of 32.8 A (vs. 5% lower). These tighter specifications make the JANTXV1N6154AUS/TR suitable for designs requiring precise overvoltage thresholds and robust surge handling - unlike the base 1N6154US or C-suffix variants.
What is the thermal resistance specification for JANTXV1N6154AUS/TR?
The JANTXV1N6154AUS/TR has a thermal resistance junction-to-end cap (RθJEC) of 5.0 °C/W. This parameter defines how effectively heat generated during surge conduction transfers from the silicon junction to the end-cap mounting surface. When soldered to adequately sized PCB copper pads, this low thermal resistance allows the JANTXV1N6154AUS/TR to sustain repeated 1500 W pulses without exceeding its 175 °C maximum junction temperature, supporting reliable operation in high-power transient scenarios.
Can JANTXV1N6154AUS/TR be used in bidirectional signal line protection?
Yes, JANTXV1N6154AUS/TR is explicitly designed as a bidirectional TVS with no polarity marking, making it suitable for protecting AC-coupled or differential signal lines such as RS-422, MIL-STD-1553, or CAN FD interfaces. Its symmetrical breakdown and clamping characteristics ensure equal protection against positive and negative transients. However, due to its 25.1 V standoff voltage, the JANTXV1N6154AUS/TR is best applied on power rails or high-voltage data lines - not low-voltage digital I/O.
