Product details
Overview
JANTXV1N6157US/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 32.7 V working peak standoff voltage (VWM), 40.9 V minimum breakdown voltage (V(BR)) at 30 mA, and clamps transients to 59.1 V at 25.4 A peak pulse current (IPP) for 10/1000 µs waveform, delivering 1500 W peak pulse power in high-reliability military and aerospace power rail protection.
For engineers reviewing the JANTXV1N6157US/TR datasheet, JANTXV1N6157US/TR pinout, JANTXV1N6157US/TR application, or JANTXV1N6157US/TR equivalent, key selection criteria include its MIL-qualified reliability level, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), standoff-to-clamp voltage ratio (VWM/VC = 0.55), and compatibility with automated SMT placement via square-end-cap terminals.
Technical Context
This TVS operates as a bidirectional voltage-clamping device with no polarity marking, relying on symmetrical avalanche breakdown in both directions. Its hard-glass hermetic package incorporates internal Category 1 metallurgical bonds and triple-layer passivation to ensure robustness against ESD (per MIL-STD-750 Method 1020), EFT (IEC61000-4-4), and lightning-induced surges (IEC61000-4-5).
It delivers stable transient suppression across -55 °C to +175 °C junction temperature range, with 0.095 %/°C temperature coefficient of breakdown voltage (αV(BR)). Thermal performance is defined by junction-to-end-cap resistance (RθJEC = 5.0 °C/W), enabling predictable derating above 150 °C end-cap temperature per linear derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 32.7 V - Maximum continuous DC or repetitive peak reverse voltage before conduction begins; sets operating margin below clamping threshold. |
| V(BR) min | 40.9 V @ 30 mA - Minimum voltage at which avalanche breakdown initiates; defines lower bound of functional clamping window. |
| VC @ IPP | 59.1 V @ 25.4 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on protected circuitry. |
| PPP | 1500 W - Peak pulse power handling capability; enables protection against high-energy transients without failure. |
| ID @ VWM | 5 µA - Standby leakage current at rated standoff voltage; ensures minimal power loss and signal integrity in standby. |
| TJ Range | -55 to +175 °C - Operational junction temperature span; supports deployment in extreme environmental conditions. |
| RθJEC | 5.0 °C/W - Junction-to-end-cap thermal resistance; critical for calculating end-cap temperature rise under pulsed or steady-state power dissipation. |
Pinout & Package
Package: Hermetically sealed voidless hard-glass surface-mount case with tungsten slugs and square-end-cap terminals; dimensions per Microsemi T4-LDS-0278-1 Rev. 2 (BD: 0.183–0.202", BL: 0.205–0.245", ECT: 0.019–0.028").
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | No polarity marking; symmetric terminals conduct equally in either direction during overvoltage events. |
| End Cap (both ends) | Thermal interface & mechanical anchor | Primary heat transfer path to PCB; requires controlled solder joint geometry per pad layout spec (A1=0.310", A2=0.170"). |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal/power lines without polarity concerns. |
| Category 1 metallurgical bonds | Guarantees bond integrity under thermal cycling and mechanical shock, meeting MIL-PRF-19500/516 JANTXV reliability requirements. |
| Triple-layer passivation | Prevents moisture ingress and surface leakage paths, ensuring long-term stability in humid or contaminated environments. |
| Voidless hermetic seal | Eliminates internal delamination risk during reflow or field operation, preserving electrical characteristics over lifetime. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6157AUS | Commercial-grade version with same VWM (32.7 V), V(BR) (40.9 V), and VC (59.1 V), but not MIL-qualified. | Lacks JANTXV reliability screening, temperature cycling, and lot traceability required for flight hardware. | Select when cost-sensitive commercial designs require identical electrical specs without military certification. |
| JANTXV1N6156US/TR | Lower VWM (29.7 V), V(BR) (37.1 V), and VC (53.6 V); 28.0 A IPP rating vs. 25.4 A for JANTXV1N6157US/TR. | Better suited for 24 V systems where tighter clamping margin is needed, but less headroom for voltage tolerance drift. | Choose for 24 V rail protection where lower clamping voltage reduces stress on downstream 30 V-rated components. |
Compared with JANTXV1N6157US/TR, 1N6157AUS offers identical electrical performance at lower cost but no MIL qualification, while JANTXV1N6156US/TR trades 3 V higher standoff for 5.5 V lower clamping-enabling tighter protection windows in lower-voltage systems.

FAQ
What is the clamping voltage of JANTXV1N6157US/TR at its rated peak pulse current?
The JANTXV1N6157US/TR has a maximum clamping voltage (VC) of 59.1 V when subjected to its rated 10/1000 µs peak pulse current of 25.4 A. This value is measured under standardized test conditions per MIL-PRF-19500/516 and defines the upper voltage limit imposed on protected circuitry during surge events. The JANTXV1N6157US/TR maintains this clamping performance across its full operational temperature range.
Is JANTXV1N6157US/TR suitable for bidirectional signal line protection?
Yes, JANTXV1N6157US/TR is explicitly designed as a bidirectional TVS with no polarity marking and symmetrical avalanche characteristics in both directions. It is commonly used to protect AC-coupled interfaces, differential buses like MIL-STD-1553B, and floating power domains where voltage reversals may occur. Its 32.7 V standoff and 59.1 V clamping apply identically regardless of terminal orientation.
What does the "JANTXV" prefix indicate for JANTXV1N6157US/TR?
The "JANTXV" prefix certifies that JANTXV1N6157US/TR meets the highest reliability tier of MIL-PRF-19500/516, including extended temperature screening (-55 °C to +175 °C), rigorous lot acceptance testing, and full traceability. JANTXV qualification exceeds JANTX and JAN levels, making JANTXV1N6157US/TR appropriate for spaceflight, strategic weapons, and other zero-failure-tolerance applications.
How does the thermal resistance of JANTXV1N6157US/TR affect its steady-state power handling?
JANTXV1N6157US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, meaning each watt of steady-state power raises the junction temperature by 5 °C above the end-cap temperature. Its rated off-state power is 5.0 W up to 150 °C end-cap temperature, then linearly derated to zero at 175 °C. Proper PCB copper area and solder joint quality are essential to maintain safe thermal paths.
Does JANTXV1N6157US/TR comply with RoHS requirements?
No, JANTXV1N6157US/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants (e.g., 1N6157AUS), not for MIL-qualified JANTXV devices. The JANTXV1N6157US/TR uses tin/lead plating per military specification and retains lead content to ensure solder joint reliability under thermal cycling and mechanical stress.
