Product details
Overview
JANTXV1N6167US/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTXV level, with 86.6 V working standoff voltage (VWM), 104.5 V minimum breakdown voltage (V(BR)), and 151.3 V clamping voltage (VC) at 9.9 A peak pulse current (IPP). It delivers 1500 W peak pulse power for 10/1000 µs transients and operates across –55 °C to +175 °C junction temperature range, deployed in high-reliability military avionics power rail protection.
For engineers reviewing the JANTXV1N6167US/TR datasheet, JANTXV1N6167US/TR pinout, JANTXV1N6167US/TR application, or JANTXV1N6167US/TR equivalent, key selection criteria include its MIL-qualified bidirectional clamping behavior, hard-glass package robustness, Category 1 metallurgical bonds, IEC61000-4-2/4-4/4-5 compliance, and thermal resistance of 5.0 °C/W from junction to end cap.
Technical Context
This TVS diode operates bidirectionally without polarity marking and uses triple-layer passivation on a voidless hermetically sealed hard-glass case with tungsten slugs. Its clamping action begins at V(BR) ≥104.5 V under 12 mA test current and limits transient energy to ≤151.3 V at 9.9 A IPP for 10/1000 µs pulses.
The device features linear derating of off-state power above 150 °C end-cap temperature, with steady-state dissipation limited to 3.0 W at 25 °C ambient and 5.0 W up to 150 °C end-cap temperature. Thermal resistance junction-to-end cap is fixed at 5.0 °C/W, enabling predictable thermal design in conduction-cooled layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 86.6 V - maximum continuous reverse/forward voltage before clamping initiates; sets operating margin below breakdown |
| V(BR) min | 104.5 V @ 12 mA - guaranteed minimum voltage at which avalanche conduction begins; defines turn-on threshold |
| VC @ IPP | 151.3 V @ 9.9 A - clamped voltage during 10/1000 µs surge; determines protected circuit's maximum overvoltage exposure |
| PPP | 1500 W - peak impulse power handling for standardized 10/1000 µs waveform; defines single-event surge survivability |
| ID @ VWM | 5 µA - leakage current at rated standoff voltage; ensures minimal standby power loss and signal integrity |
| TJ Range | –55 °C to +175 °C - operational junction temperature span; supports deployment in extreme-environment military platforms |
| RθJEC | 5.0 °C/W - thermal resistance from junction to end cap; enables direct thermal path modeling in metal-core PCBs or chassis mounts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6166US/TR | Lower VWM (76.0 V), lower VC (137.6 V @ 13.3 A), same PPP (1500 W) and package | Better suited for 24–48 V systems requiring tighter clamping margin below 140 V | Select when system max operating voltage is ≤76 V and clamping headroom must be minimized |
| JANTXV1N6168US/TR | Higher VWM (91.2 V), higher VC (165.1 V @ 9.1 A), same PPP (1500 W) and package | Optimized for 72–110 V DC systems where higher standoff prevents false triggering on ripple | Select when nominal rail exceeds 86.6 V and transient amplitude justifies higher clamping ceiling |
Compared with JANTXV1N6167US/TR, JANTXV1N6166US/TR offers tighter clamping at lower voltage rails, while JANTXV1N6168US/TR extends standoff for higher-voltage systems-both retain identical MIL-qualified construction, thermal performance, and SQ-MELF footprint, enabling voltage-tiered design reuse without layout change.

FAQ
What is the clamping voltage of JANTXV1N6167US/TR and how is it measured?
The clamping voltage (VC) of JANTXV1N6167US/TR is 151.3 V, measured at 9.9 A peak pulse current (IPP) using a standardized 10/1000 µs double-exponential current waveform. This value represents the maximum voltage imposed on protected circuitry during surge events and is guaranteed per MIL-PRF-19500/516 test conditions. JANTXV1N6167US/TR maintains this clamping performance across its full operating temperature range.
Is JANTXV1N6167US/TR suitable for bidirectional signal line protection?
Yes, JANTXV1N6167US/TR is inherently bidirectional due to its symmetrical avalanche structure and lacks polarity marking. It provides identical clamping behavior on both terminals, making it ideal for protecting AC-coupled data lines, transformer-isolated interfaces, or floating DC rails where voltage polarity reversal may occur. JANTXV1N6167US/TR has been validated for IEC61000-4-2 ESD and IEC61000-4-4 EFT on differential pairs.
What is the thermal resistance specification for JANTXV1N6167US/TR and why does it matter?
JANTXV1N6167US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W, defining the primary heat conduction path from die to PCB pad or chassis mount. This parameter is critical for predicting steady-state temperature rise under continuous power dissipation and for designing conduction-cooled layouts in high-reliability enclosures. JANTXV1N6167US/TR leverages this low RθJEC to sustain 5.0 W off-state power up to 150 °C end-cap temperature.
Does JANTXV1N6167US/TR meet IEC61000-4-5 surge immunity standards?
JANTXV1N6167US/TR provides protection against secondary effects of lightning per select levels in IEC61000-4-5, specifically supporting Level 4 (4 kV line-to-earth, 2 kV line-to-line) when applied in properly designed circuits with appropriate series impedance. Its 1500 W peak pulse power rating and 151.3 V clamping voltage enable compliant system-level surge performance. JANTXV1N6167US/TR itself is not certified to IEC61000-4-5 as a standalone device but is engineered to meet its requirements in end-equipment implementations.
How does the JANTXV qualification level affect the reliability of JANTXV1N6167US/TR?
The JANTXV qualification level certifies JANTXV1N6167US/TR to MIL-PRF-19500/516 with enhanced screening including extended temperature cycling, hermeticity testing, and lot acceptance tests beyond standard JAN or JANTX levels. This ensures superior long-term reliability in mission-critical applications such as flight control, radar, and secure communications. JANTXV1N6167US/TR undergoes rigorous process controls and traceability protocols required for JANTXV-level procurement.
