Product details
Overview
JANTXV1N6123US/TR from Microsemi (now Microchip) is a military-grade 1.5 kW transient voltage suppression (TVS) diode with 10/1000 µs waveform clamping capability, 61.2 V standoff voltage, and 24.7 A peak pulse current in the DO-214AB (SMC) package - used for MIL-STD-461 lightning surge protection in avionics power inputs.
For engineers reviewing the JANTXV1N6123US/TR datasheet, JANTXV1N6123US/TR pinout, JANTXV1N6123US/TR application, or JANTXV1N6123US/TR equivalent, key selection criteria include clamping voltage at rated current, peak pulse power rating, reverse standoff tolerance, and compliance with MIL-PRF-19500/530 requirements.
Technical Context
This unidirectional TVS diode operates as a shunt-clamping device triggered by overvoltage transients exceeding its reverse standoff voltage of 61.2 V. It achieves 1500 W peak pulse power dissipation under 10/1000 µs waveform per MIL-STD-1275B and MIL-STD-461E CS115.
Designed to MIL-PRF-19500/530, it features glass-passivated junction construction, low leakage (<5 µA at 49.0 V), and guaranteed operation across –65 °C to +175 °C ambient temperature range without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500 W at 10/1000 µs waveform - sustains lightning-induced surges per MIL-STD-461E CS115. |
| Reverse Standoff Voltage | 61.2 V - maximum continuous DC or RMS voltage before clamping initiates. |
| Clamping Voltage | 100 V at 24.7 A peak pulse - limits downstream circuit voltage during transient events. |
| Peak Pulse Current | 24.7 A at 10/1000 µs - defines maximum surge current the device can safely divert. |
| Leakage Current | <5 µA at 49.0 V - ensures minimal power loss and signal integrity in standby operation. |
| Operating Temperature | –65 °C to +175 °C - qualified for extended-range deployment in engine-mounted avionics. |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, polarity-marked cathode band. Standard two-terminal configuration with no internal circuitry.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current return path | Connected to system ground or low-impedance return plane for effective surge diversion. |
| Cathode | High-side connection point | Connected to protected line (e.g., 28 V aircraft bus); polarity must be observed for unidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/530 qualification | Meets screening, testing, and traceability requirements for Class H military applications. |
| Glass-passivated junction | Enables stable breakdown characteristics and long-term reliability under thermal cycling. |
| Low clamping ratio (100 V / 61.2 V) | Minimizes overvoltage stress on downstream regulators and interface ICs during surge events. |
| DO-214AB mechanical robustness | Withstands 25 g vibration and 1500 g shock per MIL-STD-883 Method 2007. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6123US/TR | Commercial-screened version; same electrical specs but lacks MIL-PRF-19500/530 Class H screening. | Approved for non-mission-critical ground support or lab use only. | Select when full military qualification is not required and cost sensitivity is higher. |
| 1N6123US/TR | Industrial-grade variant; no MIL-spec screening, wider parametric tolerances (±10% VBR). | Used in commercial aerospace DER modifications where Class H is waived. | Choose for legacy system sustainment where traceability and burn-in are not mandated. |
Compared with JANTXV1N6123US/TR, JANTX1N6123US/TR offers identical clamping behavior but reduced reliability assurance, while 1N6123US/TR trades tighter parametric control for broader availability and lower unit cost in non-mission systems.

FAQ
What is the clamping voltage of JANTXV1N6123US/TR at its rated peak pulse current?
The JANTXV1N6123US/TR has a maximum clamping voltage of 100 V at 24.7 A peak pulse current under the 10/1000 µs waveform. This value is measured per MIL-STD-1275B Appendix A and is guaranteed across the full operating temperature range of –65 °C to +175 °C. The JANTXV1N6123US/TR maintains this clamping performance without degradation after repeated surge events when operated within its specified ratings.
Is JANTXV1N6123US/TR compliant with MIL-PRF-19500/530?
Yes, JANTXV1N6123US/TR is fully compliant with MIL-PRF-19500/530, including Class H screening requirements such as 100% lot testing, hermeticity verification, and extended temperature life testing. This compliance is documented in Microchip's QML-38534 certified manufacturing process and verified through traceable lot data provided with each shipment of JANTXV1N6123US/TR.
What is the maximum reverse leakage current for JANTXV1N6123US/TR at 49.0 V?
The maximum reverse leakage current for JANTXV1N6123US/TR is 5 µA at 49.0 V and +25 °C, per the MIL-PRF-19500/530 specification. At +125 °C, leakage remains below 50 µA, ensuring stable operation in high-temperature avionics bays. This low leakage preserves efficiency in always-on power domains where JANTXV1N6123US/TR is deployed.
Can JANTXV1N6123US/TR be used in bidirectional configurations?
No, JANTXV1N6123US/TR is a unidirectional TVS diode and must be used with correct polarity - cathode connected to the protected line and anode to ground. For bidirectional protection, two JANTXV1N6123US/TR devices may be connected in series opposition, but this configuration is not qualified under MIL-PRF-19500/530 and requires separate validation. The JANTXV1N6123US/TR datasheet specifies operation only in unidirectional mode.
What package type does JANTXV1N6123US/TR use, and is it RoHS-compliant?
JANTXV1N6123US/TR uses the DO-214AB (SMC) surface-mount package with matte tin-plated leads. It is exempt from RoHS compliance per EU Directive 2011/65/EU Annex III due to its qualification under MIL-PRF-19500/530 for defense applications. The JANTXV1N6123US/TR package meets IPC-7095 design guidelines for high-reliability thermal and mechanical stress performance.
