Product details
Overview
JANS1N6151US/TR from Microsemi is a military-qualified, voidless hermetically sealed bidirectional Transient Voltage Suppressor (TVS) in SQ-MELF (C) package, with 18.2 V working standoff voltage (VWM), 22.8 V minimum breakdown voltage (V(BR)), and 33.3 V clamping voltage (VC) at 45.0 A peak pulse current (IPP) for 10/1000 µs waveform - deployed in avionics power rail protection.
For engineers reviewing the JANS1N6151US/TR datasheet, JANS1N6151US/TR pinout, JANS1N6151US/TR application, or JANS1N6151US/TR equivalent, key selection criteria include MIL-PRF-19500/516 JANS qualification level, 1500 W peak pulse power rating, bidirectional ESD/EFT/IEC61000-4-5 secondary lightning protection capability, and hard-glass hermetic construction for radiation-hardened environments.
Technical Context
This device operates as a bidirectional voltage-clamping protector with no polarity marking, relying on symmetrical avalanche breakdown across both terminals. Its Category 1 metallurgical bonds and voidless glass encapsulation ensure survivability under thermal cycling, mechanical shock, and ionizing radiation per MicroNote 050.
It delivers 1500 W peak pulse power (10/1000 µs) with 5.0 °C/W junction-to-end-cap thermal resistance, enabling robust transient suppression without derating in high-reliability PCB layouts where end-cap heatsinking is implemented. Standby current remains ≤5 µA at 18.2 V VWM up to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 18.2 V - maximum continuous DC or repetitive peak voltage applied without triggering conduction |
| V(BR) min | 22.8 V @ 50 mA - guaranteed avalanche onset threshold under standardized test current |
| VC @ IPP | 33.3 V @ 45.0 A - clamped voltage during full 1500 W transient, defining protected circuit's max overvoltage stress |
| PPP | 1500 W (10/1000 µs) - peak impulse energy handling capacity, critical for lightning-induced surge immunity |
| TJ range | –55 °C to +175 °C - operational envelope supporting extended-temperature military platforms |
| αV(BR) | 0.09 %/°C - predictable drift of breakdown voltage with temperature, enabling stable design margining |
| ID @ VWM | ≤5 µA - negligible leakage at rated standoff, preserving low-power system integrity |
Pinout & Package
SQ-MELF (C) surface-mount package: hermetically sealed voidless hard glass body with tungsten slugs and tin/lead-plated copper terminals; square-end-cap geometry enables precise automated placement and reliable solder joint formation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (bidirectional) | Transient conduction path | No polarity marking - symmetric terminals conduct equally in either direction during overvoltage events |
| End Cap (both ends) | Thermal interface | Primary heat dissipation path; RθJEC = 5.0 °C/W enables direct thermal coupling to PCB copper pour or metal core |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6151US | Same electrical specs but JANTXV qualification level; lower screen rigor than JANS (no radiation hardness verification) | Approved for ground-based military systems where TID tolerance is not required | Select when cost sensitivity outweighs space/avionics radiation requirements |
| 1N6151AUS | Commercial-grade version; identical VWM/V(BR)/VC/IPP but unqualified to MIL-PRF-19500/516 | Restricted to non-mission-critical industrial or test equipment | Choose only for prototyping or non-certified subsystems with full requalification path |
Compared with JANTXV1N6151US and 1N6151AUS, the JANS1N6151US/TR provides verified radiation hardness and full JANS-level screening - essential for flight-critical avionics and orbital payloads where single-event latchup or parametric drift cannot be tolerated.

FAQ
What is the clamping voltage of JANS1N6151US/TR at its rated peak pulse current?
The JANS1N6151US/TR has a maximum clamping voltage (VC) of 33.3 V at 45.0 A peak pulse current (IPP) for a 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuits during surge events and is measured under standardized conditions per MIL-PRF-19500/516. The JANS1N6151US/TR maintains this clamping performance across its full operating temperature range from –55 °C to +175 °C.
Is JANS1N6151US/TR suitable for space applications requiring radiation hardness?
Yes, the JANS1N6151US/TR is inherently radiation-hardened per Microsemi MicroNote 050, with verified tolerance to total ionizing dose (TID) ≥100 krad(Si). Its voidless hermetic glass package and Category 1 metallurgical bonds prevent degradation under proton and gamma irradiation. The JANS1N6151US/TR is routinely deployed in satellite payload power systems where single-event effects must be mitigated without derating.
Does JANS1N6151US/TR have polarity markings or directional requirements?
No, the JANS1N6151US/TR is a bidirectional TVS with no polarity markings or directional installation requirements. Its symmetrical avalanche structure allows it to clamp overvoltage transients equally in both directions, making it ideal for protecting AC-coupled interfaces, floating grounds, or battery terminals where reverse connection risk exists. The JANS1N6151US/TR functions identically regardless of orientation on the PCB.
What is the thermal resistance specification for JANS1N6151US/TR, and how does it impact layout?
The JANS1N6151US/TR has a junction-to-end-cap thermal resistance (RθJEC) of 5.0 °C/W. This low value indicates efficient heat transfer from the die to the end caps, which must be thermally anchored to large copper areas or heatsinks. For sustained operation near maximum power, PCB layout must provide ≥25 mm² of 2-oz copper per end cap, as specified in the pad layout drawing. The JANS1N6151US/TR derates linearly above 150 °C end-cap temperature.
How does JANS1N6151US/TR differ from commercial 1N6151AUS in screening and reliability?
The JANS1N6151US/TR undergoes full MIL-PRF-19500/516 JANS-level screening including burn-in, temperature cycling, and lot acceptance testing, plus radiation hardness validation. In contrast, 1N6151AUS is commercial-grade with identical electrical parameters but no military qualification or radiation data. The JANS1N6151US/TR is traceable to certified lots with 100% lot testing, whereas 1N6151AUS follows standard commercial quality flow.
