Product details
Overview
JANTX1N6164US/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 62.2 V working peak standoff voltage (VWM), 77.9 V minimum breakdown voltage (V(BR)), and clamps transients to 112.8 V at 13.3 A peak pulse current (IPP) with 1500 W peak pulse power for 10/1000 µs waveform-used in avionics power bus protection.
For engineers reviewing the JANTX1N6164US/TR datasheet, JANTX1N6164US/TR pinout, JANTX1N6164US/TR application, or JANTX1N6164US/TR equivalent, key selection criteria include military-grade reliability, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and compliance with IEC61000-4-2/4-4/4-5 for ESD, EFT, and lightning-induced surge immunity.
Technical Context
This TVS operates bidirectionally without polarity marking and uses internal Category 1 metallurgical bonds within a hard-glass hermetic package to ensure radiation hardness and long-term stability under thermal cycling. Its clamping action begins at V(BR) ≥ 77.9 V and limits transient energy across both polarities up to 1500 W for standardized 10/1000 µs pulses.
The device exhibits a temperature coefficient of breakdown voltage αV(BR) = 0.100 %/°C and maintains ≤5 µA standby current (ID) at VWM = 62.2 V. Thermal resistance from junction to end cap is 5.0 °C/W, enabling robust operation up to +175 °C junction temperature with linear derating above +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 62.2 V maximum continuous standoff voltage-defines highest DC/repetitive peak voltage before conduction begins |
| V(BR) min | 77.9 V at 15 mA-guaranteed avalanche onset threshold under specified test current |
| VC @ IPP | 112.8 V at 13.3 A-maximum clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPP | 1500 W for 10/1000 µs-peak transient energy absorption capacity per single event |
| ID @ VWM | ≤5 µA-leakage current at rated standoff, ensuring minimal power loss in standby |
| RθJEC | 5.0 °C/W-thermal resistance from junction to end cap, critical for thermal design in high-power surges |
| TJ/TSTG | –55 to +175 °C-operating and storage range supporting extended military environmental profiles |
Pinout & Package
Package: SQ-MELF (C-package variant), voidless hermetically sealed hard-glass case with tungsten slugs and tin/lead-plated copper terminals. No polarity marking due to bidirectional symmetry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either end functions identically as conduction path during positive or negative transients |
| End Cap (both ends) | Thermal and mechanical interface | Primary heat dissipation path to PCB pad; defines RθJEC = 5.0 °C/W rating |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC lines or ungrounded differential buses without polarity concerns |
| Category 1 metallurgical bonds | Ensures bond integrity under shock, vibration, and thermal cycling-required for MIL-PRF-19500/516 qualification |
| Voidless hermetic seal | Prevents moisture ingress and internal corrosion over decades of field operation in harsh environments |
| IEC61000-4-5 compliance | Validated protection against lightning-induced surges up to select levels, reducing need for external filtering |
Applications
| Avionics Power Bus Protection | Military Radio Front-End |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6164US | No JANTX screening; commercial grade only; same electrical specs but no MIL-PRF-19500/516 qualification | Lacks military reliability testing-unsuitable for flight-critical or JANTX-mandated programs | Select only for cost-sensitive non-military prototypes or ground-test fixtures |
| JANTXV1N6164US | Higher screening level (JANTXV); includes burn-in, life test, and enhanced lot traceability per MIL-PRF-19500/516 | Required for space-grade or mission-critical systems where failure risk must be minimized beyond JANTX | Choose when program spec mandates JANTXV-level assurance or extended lifetime validation |
Compared with JANTX1N6164US/TR, the commercial 1N6164US omits military screening and traceability, while JANTXV1N6164US adds burn-in and life testing-making JANTX the balanced choice for defense electronics requiring certified reliability without full space-grade rigor.

FAQ
What is the clamping voltage of JANTX1N6164US/TR at its rated peak pulse current?
The JANTX1N6164US/TR has a maximum clamping voltage (VC) of 112.8 V when subjected to its rated peak pulse current (IPP) of 13.3 A under the standard 10/1000 µs waveform. This value is guaranteed per MIL-PRF-19500/516 test conditions and reflects worst-case conduction behavior during surge events. The JANTX1N6164US/TR maintains this clamping performance across its full operating temperature range.
Is JANTX1N6164US/TR RoHS compliant?
No, JANTX1N6164US/TR is not RoHS compliant. Per the manufacturer's nomenclature and datasheet, RoHS-compliant versions (marked with "e3") are available only for commercial-grade variants-not for JAN, JANTX, JANTXV, or JANS qualified parts like JANTX1N6164US/TR. The JANTX1N6164US/TR uses tin/lead plating on copper terminals to meet military solderability and reliability standards.
What does the "TR" suffix indicate in JANTX1N6164US/TR?
The "TR" suffix in JANTX1N6164US/TR denotes tape-and-reel packaging per EIA-481-B standard, intended for automated SMT placement. It confirms the part is supplied in industry-standard carrier tape with specified pocket dimensions, orientation, and reel quantities. The JANTX1N6164US/TR retains identical electrical and reliability specifications as the bulk or ammo-pack versions of the same JANTX-qualified device.
How does JANTX1N6164US/TR differ from the non-A version (e.g., JANTX1N6164US)?
The "A" in JANTX1N6164US/TR indicates tighter voltage tolerances: minimum breakdown voltage is 5% higher, clamping voltage (VC) is 5% lower, and peak pulse current (IPP) is 5% higher than the non-A version. The JANTX1N6164US/TR meets these A-version specs per datasheet Table on Page 3, whereas JANTX1N6164US would exhibit looser parametric bounds unsuitable for precision surge margining.
Can JANTX1N6164US/TR be used in place of axial-leaded 1N6164 parts?
No-JANTX1N6164US/TR is a surface-mount SQ-MELF (C-package) device, while axial-leaded 1N6164 variants use through-hole construction with different thermal paths and mounting mechanics. Though electrically similar, the JANTX1N6164US/TR requires reflow-compatible PCB pads and cannot be substituted without layout revision. Its RθJEC = 5.0 °C/W is defined relative to end-cap solder joints, not lead-frame thermal resistance.
