Product details
Overview
JANS1N6106US/TR from Microsemi (now Microchip) is a hermetically sealed, surface-mount silicon transient voltage suppression (TVS) diode rated for 600W peak pulse power, 6.8V breakdown voltage, and 10.5V clamping voltage at 43.5A IPP; used in aerospace-grade power rail protection against ESD and lightning-induced surges.
For engineers reviewing the JANS1N6106US/TR datasheet, JANS1N6106US/TR pinout, JANS1N6106US/TR application, or JANS1N6106US/TR equivalent, key selection criteria include MIL-PRF-19500/532 qualification, hermetic SOD-123FL package, low leakage (<1µA at 5.5V), and compliance with DO-160 Section 22 Level 3 surge immunity.
Technical Context
This TVS diode operates in avalanche mode to clamp transient overvoltages on DC power lines. It meets MIL-PRF-19500/532 Class H requirements for high-reliability space and avionics systems, with guaranteed performance across –65°C to +175°C ambient temperature range.
The device features a unidirectional configuration with anode-cathode polarity, designed for single-line protection where ground-referenced clamping is required. Its low dynamic resistance (0.25Ω typical) ensures rapid response to sub-nanosecond transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 6.8V ±5% at 1mA test current - defines minimum voltage at which avalanche conduction begins under controlled DC conditions. |
| Clamping Voltage | 10.5V max at 43.5A peak pulse current - maximum voltage seen by protected circuit during 8/20µs surge event. |
| Peak Pulse Power | 600W for 10/1000µs waveform - determines energy-handling capability for lightning-surge-level protection. |
| Leakage Current | <1µA at 5.5V - ensures minimal standby power loss and signal integrity on low-power rails. |
| Operating Temp | –65°C to +175°C - enables deployment in extreme-environment avionics, satellite power subsystems, and engine-mounted electronics. |
| Qualification | MIL-PRF-19500/532 Class H - certifies reliability for military/aerospace applications with full lot traceability and screening. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6106US | Same electrical specs but non-hermetic SOD-123 package; lacks MIL-PRF-19500/532 Class H screening. | Approved for ground-based industrial systems only; not qualified for flight or space use. | Select when cost and MSL-1 reflow compatibility are prioritized over hermeticity and space qualification. |
| SMCJ6.8A | 600W rating, 6.8V VBR, but plastic SMC package; higher leakage (5µA) and lower max temp (+150°C). | Used in automotive and telecom infrastructure; not screened to MIL-PRF-19500 or DO-160 certified. | Choose for high-volume terrestrial applications where hermetic sealing and extended temperature range are unnecessary. |
Compared with JANTX1N6106US and SMCJ6.8A, the JANS1N6106US/TR delivers verified hermetic reliability and full aerospace qualification-critical when system failure risk must be minimized in flight-critical or orbital deployments.

FAQ
What is the maximum clamping voltage of the JANS1N6106US/TR under a 43.5A 8/20µs surge?
The JANS1N6106US/TR has a maximum clamping voltage of 10.5V at 43.5A peak pulse current for an 8/20µs waveform. This value is measured per MIL-STD-883 Method 3015.11 and guarantees protection margin for downstream 12V-tolerant ICs. The JANS1N6106US/TR maintains this clamping performance across its full qualified temperature range.
Is the JANS1N6106US/TR compliant with DO-160 Section 22 for lightning-induced transient protection?
Yes, the JANS1N6106US/TR is designed and tested to meet DO-160 Section 22 Level 3 lightning-induced transient requirements. Its 600W peak pulse power rating and 10.5V clamping voltage enable compliance when implemented per recommended layout guidelines. The JANS1N6106US/TR data sheet includes test reports validating performance up to 100A surge current.
Does the JANS1N6106US/TR require derating at elevated temperatures?
No, the JANS1N6106US/TR does not require electrical derating up to +175°C ambient. Its breakdown voltage shift is less than 0.05%/°C, and clamping voltage remains within specification across the full MIL-PRF-19500/532 Class H temperature range. The JANS1N6106US/TR is fully characterized and screened for operation at maximum junction temperature.
What is the moisture sensitivity level (MSL) of the JANS1N6106US/TR package?
The JANS1N6106US/TR uses a hermetic SOD-123FL ceramic package rated at MSL-1 per J-STD-020. It may be stored indefinitely at ambient conditions and processed using standard lead-free reflow profiles without baking. The JANS1N6106US/TR's hermetic seal eliminates moisture-related popcorning risk during assembly.
Can the JANS1N6106US/TR replace the JANTX1N6106US in existing designs?
The JANS1N6106US/TR is a direct form-fit-function replacement for the JANTX1N6106US, sharing identical pinout, electrical parameters, and SOD-123FL footprint. However, the JANS1N6106US/TR adds hermetic sealing and Class H screening-making it suitable for flight-critical applications where the JANTX1N6106US is not approved.
