Product details
Overview
JANS1N6148US/TR from Microsemi is a military-qualified, voidless hermetically sealed bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF package, rated for 1500 W peak pulse power (10/1000 µs), 13.7 V working standoff voltage (VWM), and 25.1 V clamping voltage (VC) at 59.8 A peak pulse current - deployed in avionics power rail protection and MIL-STD-461E transient suppression.
For engineers reviewing the JANS1N6148US/TR datasheet, JANS1N6148US/TR pinout, JANS1N6148US/TR application, or JANS1N6148US/TR equivalent, key selection criteria include its JANS-level qualification per MIL-PRF-19500/516, Category 1 metallurgical bonds, -55°C to +175°C operating range, and IEC61000-4-5 lightning surge compliance.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses hard-glass construction with tungsten slugs for thermal robustness. Its breakdown voltage is 17.10 V at 65 mA (VBR), with a temperature coefficient of 0.085 %/°C and standby leakage ≤10 µA at VWM.
The device delivers 1500 W peak pulse power into a 10/1000 µs waveform, with thermal resistance junction-to-end cap at 5.0 °C/W. It is RoHS-compliant only in commercial versions; JANS1N6148US/TR retains SnPb terminations and is not RoHS-compliant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13.7 V - maximum continuous DC or repetitive peak reverse voltage before conduction begins |
| VBR @ IBR | 17.10 V at 65 mA - precise voltage threshold where avalanche breakdown initiates |
| VC @ IPP | 25.1 V at 59.8 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPP | 1500 W - peak transient energy handling capability under standard impulse waveform |
| ID @ VWM | ≤10 µA - ultra-low leakage ensures minimal standby power loss in high-impedance circuits |
| TJ/TSTG | -55°C to +175°C - extended temperature range supports operation in harsh military environments |
| αVBR | 0.085 %/°C - predictable VBR drift over temperature enables stable design margins |
Pinout & Package
SQ-MELF (Square-End-Cap Metal Electrode Leadless Face) package: hermetically sealed voidless hard glass body with tungsten slugs and tin/lead-plated copper terminals. Dimensions: BD = 4.65–5.13 mm, BL = 5.21–6.22 mm, ECT = 0.48–0.71 mm. No polarity marking; bidirectional operation requires no orientation during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional avalanche junction | Either end serves as anode or cathode depending on transient polarity; no dedicated pin assignment |
| End Cap (both ends) | Thermal and electrical interface | Directly contacts PCB pads for low-inductance surge path and heat dissipation via end-cap mounting |
Key Features
| Feature | Design Value |
|---|---|
| Voidless hermetic glass seal | Eliminates internal delamination risk under thermal cycling and humidity, ensuring long-term reliability in sealed enclosures |
| Category 1 metallurgical bonds | Guarantees bond integrity per MIL-STD-750 Method 2035, critical for radiation-hardened and high-vibration platforms |
| JANS qualification per MIL-PRF-19500/516 | Validated screening includes burn-in, temperature cycling, and lot acceptance testing for space- and defense-critical systems |
| Triple-layer passivation | Protects junction surface from contamination and moisture ingress, maintaining VBR stability over 20+ years in storage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6148US | Same VWM, VBR, VC, and PPP; qualified to JANTXV level (lower screening rigor than JANS) | Lacks full JANS radiation hardness validation and extended life test requirements | Select when full JANS qualification is not mandated but MIL-PRF-19500/516 compliance is required |
| 1N6148AUS (commercial) | Identical electrical specs; RoHS-compliant matte-tin terminations; no MIL-PRF-19500/516 qualification | Not suitable for flight hardware or nuclear-hardened systems; limited to ground-test or non-safety-critical use | Select for cost-sensitive prototyping or commercial subsystems where military screening is unnecessary |
Compared with JANTXV1N6148US and 1N6148AUS, JANS1N6148US/TR provides the highest assurance of performance under extreme thermal, radiation, and mechanical stress - essential for launch-critical and strategic defense electronics where failure is not an option.

FAQ
What is the clamping voltage of JANS1N6148US/TR and how is it verified?
The clamping voltage (VC) of JANS1N6148US/TR is 25.1 V measured at 59.8 A peak pulse current under a 10/1000 µs waveform per MIL-STD-750 Method 3019. This value is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0278-1 Rev. 2. JANS1N6148US/TR maintains this clamping performance across its full operating temperature range (-55°C to +175°C) due to its hard-glass construction and Category 1 metallurgical bonds.
Is JANS1N6148US/TR RoHS compliant?
No, JANS1N6148US/TR is not RoHS compliant. It uses traditional tin/lead (SnPb) plating on copper terminals per MIL-PRF-19500/516 requirements for JANS-level devices. RoHS-compliant matte-tin terminations are available only on commercial-grade variants such as 1N6148AUS, which lack military qualification.
What does the "TR" suffix indicate in JANS1N6148US/TR?
The "TR" suffix in JANS1N6148US/TR denotes tape-and-reel packaging per EIA-481-B standard, enabling automated SMT placement. The device is supplied in hermetically sealed reels with proper moisture sensitivity labeling and dry-packaging per MIL-STD-1288, consistent with JANS handling requirements.
How does JANS1N6148US/TR differ from the non-"A" version 1N6148US?
JANS1N6148US/TR has tighter tolerances: its VC is 5% lower, minimum VBR is 5% higher, and IPP is 5% higher than the non-A version. For example, the non-A 1N6148US would have VC ≈ 26.4 V instead of 25.1 V. These differences are defined in the Nomenclature section of T4-LDS-0278-1 Rev. 2.
Can JANS1N6148US/TR be used in place of JANTXV1N6148US?
JANS1N6148US/TR is not a drop-in replacement for JANTXV1N6148US due to stricter screening, additional radiation hardness validation, and extended life testing per JANS requirements. While electrically identical, JANS1N6148US/TR requires full requalification if substituted in a JANTXV-qualified design - especially for flight or nuclear applications where process traceability and test coverage differ.
