Product details
Overview
JAN1N6151AUS/TR from Microsemi is a voidless hermetically sealed, bidirectional Transient Voltage Suppressor (TVS) qualified to MIL-PRF-19500/516 at JAN reliability level. It features a 18.2 V working peak standoff voltage (VWM), 22.8 V minimum breakdown voltage (V(BR)), 33.3 V clamping voltage (VC) at 45 A peak pulse current (IPP), and 1500 W peak pulse power for 10/1000 µs waveform - deployed in high-reliability military avionics power rail protection.
For engineers reviewing the JAN1N6151AUS/TR datasheet, JAN1N6151AUS/TR pinout, JAN1N6151AUS/TR application, or JAN1N6151AUS/TR equivalent, key selection criteria include its MIL-qualified JAN-level reliability, bidirectional clamping behavior, hard-glass SQ-MELF package, and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning-induced surge suppression.
Technical Context
This TVS operates bidirectionally with no polarity marking and uses internal Category 1 metallurgical bonds for radiation-hardened, high-reliability performance. Its voidless hermetically sealed hard-glass construction ensures stable V(BR) drift (αV(BR) = 0.09 %/°C) and withstands junction temperatures from –55 °C to +175 °C.
The device delivers 1500 W peak pulse power under 10/1000 µs waveform while maintaining 5 µA standby current (ID) at VWM and 33.3 V clamping across 45 A impulse - enabling robust secondary lightning surge suppression in aerospace power distribution units without polarity constraints.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6151US/TR | No JAN qualification; commercial-grade only, same electrical specs but no MIL screening or traceability | Acceptable for non-mission-critical industrial controls where cost outweighs reliability requirements | Select when full MIL-PRF-19500/516 compliance is not mandated and RoHS compliance is required |
| JANTX1N6151AUS/TR | Higher screening level (JANTX) with additional burn-in and parametric testing; identical VWM, VC, and PPP | Required for airborne platforms requiring extended life test data and lot traceability beyond JAN baseline | Choose when system certification demands enhanced reliability evidence beyond JAN-level screening |
Compared with JAN1N6151AUS/TR, 1N6151US/TR reduces procurement cost and enables RoHS compliance but forfeits military qualification, while JANTX1N6151AUS/TR adds screening rigor for longer field life - making JAN1N6151AUS/TR the optimal balance of certified reliability and supply chain accessibility for defense prime integrators.

FAQ
What is the clamping voltage of JAN1N6151AUS/TR and how is it validated?
JAN1N6151AUS/TR has a maximum clamping voltage (VC) of 33.3 V measured at 45 A peak pulse current under 10/1000 µs waveform per MIL-PRF-19500/516 test conditions. This value is confirmed in the official Microsemi T4-LDS-0278-1 datasheet, Page 3, Electrical Characteristics table. The clamping performance remains stable across –55 °C to +175 °C junction temperature, and JAN1N6151AUS/TR is screened to ensure VC consistency in every production lot.
Is JAN1N6151AUS/TR RoHS compliant?
No, JAN1N6151AUS/TR is not RoHS compliant. Per the Microsemi nomenclature guide, the "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N6151AUS/TR-e3); JAN-level parts use tin/lead plating per MIL-spec and retain lead content for solderability and reliability in high-temperature reflow profiles. JAN1N6151AUS/TR maintains full MIL-PRF-19500/516 qualification, which requires non-RoHS terminations.
What package type does JAN1N6151AUS/TR use and what are its mounting requirements?
JAN1N6151AUS/TR uses the SQ-MELF (Square-end-cap Metal Electrode Leadless Face) package - a hermetically sealed voidless hard-glass body with tungsten slugs and tin/lead-plated copper terminals. Mounting requires standard SMT reflow per JEDEC J-STD-020, with peak temperature up to 260 °C for 10 seconds. Pad layout follows Microsemi's recommended dimensions on Page 7, including optional center adhesive spot (0.090″ diameter) if mechanical reinforcement is needed.
How does JAN1N6151AUS/TR differ from the non-"A" version (e.g., JAN1N6151US/TR)?
JAN1N6151AUS/TR specifies tighter voltage tolerances: its minimum breakdown voltage (22.8 V) and clamping voltage (33.3 V) are 5% higher than the non-A version, while peak pulse current (45 A) is 5% higher. The "A" suffix also guarantees lower V(BR) variation and improved consistency for precision surge protection. JAN1N6151AUS/TR is explicitly listed in the datasheet's Electrical Characteristics table; JAN1N6151US/TR is not - confirming the "A" variant is the qualified, characterized version.
Does JAN1N6151AUS/TR require polarity-aware PCB layout?
No, JAN1N6151AUS/TR is a bidirectional TVS with no polarity marking and symmetrical terminal construction. Either end functions identically as anode or cathode depending on transient polarity, eliminating orientation constraints during placement. This simplifies layout in differential or AC-coupled circuits and avoids risk of reverse installation - a key advantage over unidirectional TVS devices like SMAJ18A.
