Product details
Overview
JAN1N6151US/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), 18.2 V working standoff voltage (VWM), and 33.3 V clamping voltage (VC) at 45 A peak pulse current. It operates across –55 °C to +175 °C and is used in high-reliability avionics power rail protection.
For engineers reviewing the JAN1N6151US/TR datasheet, JAN1N6151US/TR pinout, JAN1N6151US/TR application, or JAN1N6151US/TR equivalent, key selection criteria include its MIL-PRF-19500/516 JAN-level qualification, bidirectional clamping behavior, glass-body thermal resistance (5.0 °C/W), and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and lightning surge immunity.
Technical Context
This device functions as a voltage-clamped shunt protector with symmetric bidirectional breakdown, enabling suppression of both positive and negative transients without polarity sensitivity. Its hard-glass construction uses internal Category 1 metallurgical bonds and triple-layer passivation to ensure robustness under repeated surge stress and radiation-hardened operation per MicroNote 050.
The JAN1N6151US/TR exhibits a temperature coefficient of breakdown voltage (αVBR) of 0.09 %/°C and linearly derates from full 1500 W pulse power at 25 °C to zero at 175 °C junction temperature. Standby current remains ≤5 µA at 18.2 V VWM, confirming low leakage in standby operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1500 W - sustains single high-energy surges without failure in aerospace power interfaces |
| Working Standoff Voltage (VWM) | 18.2 V - maximum continuous DC/repetitive voltage before conduction begins |
| Clamping Voltage (VC @ IPP) | 33.3 V at 45 A - limits transient overvoltage to safe levels for downstream 24 V logic or analog circuitry |
| Breakdown Voltage (VBR @ IBR) | 22.8 V at 50 mA - defines onset of avalanche conduction with tight tolerance control |
| Operating Temperature Range | –55 °C to +175 °C - supports deployment in engine bay, satellite payload, and missile guidance systems |
| Thermal Resistance (Junction-to-End Cap) | 5.0 °C/W - enables direct heat transfer to PCB copper or heatsink via end-cap mounting |
Pinout & Package

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-level screening (enhanced burn-in, life test, and lot acceptance); higher cost and longer lead time | Required for space-grade or critical flight hardware where extended reliability validation is mandated | Select when full JANTXV qualification documentation and traceability are contractually required |
| 1N6151AUS | Commercial-grade version; identical VWM, VC, and PPP ratings but no MIL-PRF-19500/516 qualification or radiation hardness data | Suitable for non-military industrial controls or test equipment where cost and availability outweigh qualification needs | Choose for prototyping or commercial derivatives where JAN-level screening is unnecessary |
Compared with JANTXV1N6151US and 1N6151AUS, the JAN1N6151US/TR delivers verified JAN-level reliability with documented MIL-PRF-19500/516 compliance and radiation hardness-making it the only option qualified for deployed tactical systems requiring DoD traceability and survivability under extreme environmental stress.

FAQ
What is the clamping voltage of JAN1N6151US/TR and how does it protect downstream circuitry?
The JAN1N6151US/TR has a maximum clamping voltage (VC) of 33.3 V at 45 A peak pulse current (10/1000 µs). This ensures that during a surge event, the voltage seen by protected components-such as 24 V-rated PMICs or microcontrollers-never exceeds 33.3 V, staying well within safe operating limits. Its fast response and symmetric bidirectional structure allow it to clamp both polarities equally, making JAN1N6151US/TR ideal for ungrounded or floating bus architectures common in avionics.
Is JAN1N6151US/TR RoHS compliant?
No, JAN1N6151US/TR is not RoHS compliant. Per Microsemi T4-LDS-0278-1 Rev. 2, RoHS-compliant versions (e3 marking) are available only for commercial-grade variants (e.g., 1N6151AUS), not for JAN-level parts. The JAN1N6151US/TR uses tin/lead plating on copper terminals and is manufactured to meet MIL-PRF-19500/516 requirements, which permit Pb-containing finishes for reliability-critical applications.
What does the "TR" suffix in JAN1N6151US/TR indicate?
The "TR" suffix in JAN1N6151US/TR denotes tape-and-reel packaging per EIA-481-B standard, enabling automated SMT placement. This differs from bulk or ammo-pack options and confirms the part is supplied in industry-standard carrier tape with sprocket holes, 12 mm tape width, and specified reel quantities. All electrical and reliability specifications of JAN1N6151US/TR remain identical to the base JAN1N6151US part.
How does JAN1N6151US/TR differ from the non-"A" version (e.g., JAN1N6151US)?
The "A" in JAN1N6151US/TR indicates tighter voltage tolerances: minimum breakdown voltage is 22.8 V (vs. 5% lower for non-A), clamping voltage is 33.3 V (vs. 5% higher for non-A), and peak pulse current is 45 A (vs. 5% lower for non-A). These improvements result from enhanced process control and screening-making JAN1N6151US/TR more precise and robust for mission-critical applications than the baseline JAN1N6151US.
Can JAN1N6151US/TR be used in place of axial-leaded 1N6151 parts?
No-JAN1N6151US/TR is a surface-mount SQ-MELF device, while axial-leaded 1N6151 parts use through-hole TO-204AA (DO-4) packaging. Although electrically similar, their mechanical form, thermal path, and PCB layout requirements differ significantly. Substituting JAN1N6151US/TR for an axial part requires redesigning the footprint, revalidating thermal performance, and verifying mechanical retention-so it is not a drop-in replacement.
