Product details
Overview
JANTX1N6162US/TR from Microsemi is a voidless hermetically sealed surface-mount bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JANTX level. It provides 51.7 V working peak standoff voltage (VWM), 64.6 V minimum breakdown voltage (V(BR)) at 20 mA, and clamps transients to 97.1 V at 15.4 A (10/1000 µs pulse), delivering 1500 W peak pulse power for lightning surge and ESD protection in avionics power interfaces.
For engineers reviewing the JANTX1N6162US/TR datasheet, JANTX1N6162US/TR pinout, JANTX1N6162US/TR application, or JANTX1N6162US/TR equivalent, key selection criteria include its military-grade reliability, bidirectional clamping behavior, hard-glass SQ-MELF package, and compliance with IEC61000-4-2/4-4/4-5 for high-integrity defense and aerospace systems.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses internal Category 1 metallurgical bonds for radiation-hardened performance per MicroNote 050. Its voidless hermetic glass construction ensures long-term stability under thermal cycling and humidity exposure in sealed enclosures.
It delivers 1500 W peak pulse power at 10/1000 µs waveform with 5.0 °C/W junction-to-end-cap thermal resistance, enabling robust transient suppression without derating in conduction-cooled mounting configurations. Standby current is limited to 5 µA at VWM, minimizing leakage in low-power standby circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 51.7 V - Maximum continuous reverse/forward voltage before clamping begins; sets operating margin for 48 V DC power rails. |
| V(BR) min | 64.6 V @ 20 mA - Confirmed breakdown threshold; defines onset of avalanche conduction during overvoltage events. |
| VC @ IPP | 97.1 V @ 15.4 A - Clamping voltage under 10/1000 µs surge; determines maximum stress on downstream ICs. |
| PPP | 1500 W - Peak pulse power rating; supports IEC61000-4-5 Level 3 (1 kV line-earth) surge immunity. |
| ID @ VWM | 5 µA - Ultra-low leakage at rated standoff; avoids loading sensitive reference or monitoring circuits. |
| TJ range | –55 °C to +175 °C - Full military temperature range; validated for engine bay and space-qualified electronics. |
| αV(BR) | 0.100 %/°C - Temperature coefficient of breakdown voltage; enables predictable clamping shift across thermal extremes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6162US/TR (commercial grade) | No MIL-PRF-19500/516 qualification; same electrical specs but lower reliability screening. | Acceptable for non-mission-critical ground-based industrial equipment with lower environmental stress. | Select only when JANTX-level burn-in, lot traceability, and radiation tolerance are not required. |
| JANTXV1N6162US/TR | Higher screening level (JANTXV): extended temperature testing, enhanced lot acceptance, tighter parametric limits. | Required for flight hardware, nuclear command systems, or applications demanding zero latent defects. | Choose when full JANTXV qualification-beyond JANTX-is mandated by program specification. |
Compared with JANTX1N6162US/TR, the commercial 1N6162US/TR reduces cost and lead time but sacrifices military reliability assurance, while JANTXV1N6162US/TR adds screening rigor for ultra-high-assurance platforms-neither is pin-compatible in qualification context, though all share identical SQ-MELF mechanical form.

FAQ
What is the clamping voltage of JANTX1N6162US/TR under a 10/1000 µs surge?
The JANTX1N6162US/TR clamps to a maximum of 97.1 V when subjected to a 15.4 A peak pulse current with a 10/1000 µs waveform. This value is measured and guaranteed per the datasheet's Electrical Characteristics table and defines the upper voltage limit imposed on protected circuitry during surge events. The JANTX1N6162US/TR maintains this clamping performance across its full –55 °C to +175 °C operating junction temperature range.
Is JANTX1N6162US/TR RoHS compliant?
No, JANTX1N6162US/TR is not RoHS compliant. Per the nomenclature section in the datasheet, the "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N6162AUS/TR), while JANTX-level parts retain tin/lead terminations to meet MIL-PRF-19500/516 solderability and reliability requirements. The JANTX1N6162US/TR uses standard SnPb plating over copper terminals.
Does JANTX1N6162US/TR require polarity-aware PCB layout?
No, JANTX1N6162US/TR does not require polarity-aware layout. As a bidirectional TVS, it has no anode or cathode designation-both ends are functionally identical. The device is marked with no polarity indicators, and its symmetric SQ-MELF package allows rotation during placement. This simplifies automated assembly and eliminates orientation errors in high-reliability PCB manufacturing for the JANTX1N6162US/TR.
What is the maximum steady-state power dissipation of JANTX1N6162US/TR at 25 °C ambient?
The JANTX1N6162US/TR has a steady-state power dissipation rating of 3.0 W at TA = 25 °C, as specified in the Maximum Ratings table. This value assumes adequate PCB copper area for thermal conduction; derating is required above 25 °C ambient per Figure 4 in the datasheet. At end-cap temperature (TEC) = 150 °C, the allowable power drops linearly to zero at TEC = 175 °C.
How does JANTX1N6162US/TR differ from the "A" suffix version (e.g., JANTX1N6162AUS/TR)?
The "A" suffix (e.g., JANTX1N6162AUS/TR) denotes tighter voltage tolerances: ±5% on V(BR) and VC, versus the base part's wider tolerance. The JANTX1N6162US/TR has no "A" suffix and therefore follows the standard tolerance band-confirmed in the Nomenclature section as having 5% higher VC, 5% lower minimum V(BR), and 5% lower IPP than the "A" version. Both share identical packaging and qualification level.
