Product details
Overview
JAN1N6145AUS/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), 9.9 V working standoff voltage (VWM), and 18.2 V clamping voltage (VC) at 82.4 A peak pulse current - deployed in avionics power bus protection and radar front-end ESD hardening.
For engineers reviewing the JAN1N6145AUS/TR datasheet, JAN1N6145AUS/TR pinout, JAN1N6145AUS/TR application, or JAN1N6145AUS/TR equivalent, key selection criteria include MIL-PRF-19500/516 qualification level (JAN), bidirectional clamping symmetry, glass-body thermal resistance (5.0 °C/W), and IEC61000-4-2/4-4/4-5 compliance for high-reliability transient suppression.
Technical Context
This device operates as a bidirectional avalanche diode with no polarity marking, leveraging Category 1 metallurgical bonds and triple-layer passivation to sustain repeated 1500 W transients without degradation. Its 9.9 V VWM and 12.35 V minimum breakdown voltage (VBR @ 100 mA) define precise overvoltage thresholding in DC power rails.
Thermal design relies on junction-to-end-cap resistance of 5.0 °C/W, enabling stable operation up to +175 °C junction temperature. It meets MIL-STD-750 Method 1020 for ESD insensitivity and exhibits inherent radiation hardness per MicroNote 050.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 9.9 V - Maximum continuous DC voltage applied without conduction; sets operating margin before clamping onset. |
| VC @ IPP | 18.2 V at 82.4 A - Clamped voltage during 10/1000 µs surge; defines worst-case rail excursion under fault. |
| Peak Pulse Power | 1500 W - Sustains lightning-induced surges per IEC61000-4-5 Level 3 without failure. |
| VBR min | 12.35 V @ 100 mA - Guaranteed avalanche initiation voltage; ensures consistent turn-on across temperature. |
| TJ/TSTG | –55 °C to +175 °C - Enables deployment in missile guidance systems and satellite power conditioning. |
| αV(BR) | 0.08 %/°C - Predictable VBR drift over temperature; supports stable protection thresholds in wide-temp environments. |
Pinout & Package
SQ-MELF (Square-End-Cap Metal Electrode Leadless Face) glass package with two symmetrical end-cap terminals; hermetically sealed, voidless construction; weight ≈ 1100 mg; RoHS-compliant matte-tin plating available only on commercial-grade variants.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6145AUS | Commercial-grade version; same VWM, VC, and PPP but lacks JAN-level screening and MIL-PRF-19500/516 qualification. | Approved for non-mission-critical industrial controls; not cleared for flight hardware or nuclear command systems. | Select when cost sensitivity outweighs mandatory military qualification and full radiation hardness is not required. |
| JANTX1N6145AUS | Higher screening level than JAN: includes extended burn-in, parametric lot acceptance testing, and tighter VBR limits (±5% vs JAN's ±10%). | Required for Class S spaceflight components and DoD Tier 1 avionics where failure probability must be <1×10−6. | Choose when system safety integrity level (ASIL D or DAL A) mandates enhanced process control and traceability. |
Compared with JAN1N6145AUS/TR, the commercial 1N6145AUS reduces procurement cost and lead time but forfeits MIL-qualified reliability evidence, while JANTX1N6145AUS adds screening rigor and tighter parametric bounds at higher unit cost and longer qualification cycles.

FAQ
What is the clamping voltage of JAN1N6145AUS/TR and how is it measured?
The clamping voltage (VC) of JAN1N6145AUS/TR is 18.2 V, measured at 82.4 A peak pulse current (IPP) using a standardized 10/1000 µs double-exponential waveform per IEC61000-4-5. This value reflects the maximum voltage seen across the device during surge conduction and is guaranteed across the full –55 °C to +175 °C junction temperature range. JAN1N6145AUS/TR maintains this clamping performance due to its Category 1 metallurgical bonds and voidless glass construction.
Is JAN1N6145AUS/TR RoHS compliant?
No, JAN1N6145AUS/TR is not RoHS compliant. Per the datasheet, RoHS-compliant matte-tin plating is available only on commercial-grade versions (e.g., 1N6145AUS), not on JAN-level qualified parts. The JAN1N6145AUS/TR uses traditional tin/lead plating over copper terminals to meet MIL-PRF-19500/516 solderability and reliability requirements, including compatibility with legacy military assembly processes.
What does the "A" suffix in JAN1N6145AUS/TR signify?
Per Microsemi's nomenclature, the "A" suffix in JAN1N6145AUS/TR indicates standard voltage tolerance: ±10% on VBR, ±5% on VC, and ±10% on IPP. Non-A versions (e.g., JAN1N6145US) have 5% higher VC, 5% lower minimum VBR, and 5% lower IPP. The "TR" denotes tape-and-reel packaging per EIA-481-B, and "JAN" specifies the lowest military reliability level per MIL-PRF-19500/516.
How does JAN1N6145AUS/TR differ from commercial 1N6145AUS in thermal performance?
JAN1N6145AUS/TR and commercial 1N6145AUS share identical thermal resistance (RθJEC = 5.0 °C/W) and junction temperature range (–55 °C to +175 °C), but JAN1N6145AUS/TR undergoes additional thermal cycling validation (MIL-STD-883 Method 1010) and burn-in to ensure stability under sustained thermal stress. The JAN1N6145AUS/TR's hermetic seal and Category 1 bonds prevent parameter drift after 1000 cycles between –55 °C and +125 °C.
Can JAN1N6145AUS/TR be used in bidirectional AC line protection?
Yes, JAN1N6145AUS/TR is inherently bidirectional and suitable for AC line protection where peak working voltage remains ≤9.9 V RMS (e.g., low-voltage sensor signal lines or auxiliary control circuits). Its symmetrical VBR and clamping behavior enable equal protection in both polarities. However, it is not rated for mains-voltage AC applications (e.g., 120/240 VAC) due to insufficient VWM; for such use, higher-VWM variants like JAN1N6169AUS (98.8 V) are specified.
