Product details
Overview
JANTXV1N6135AUS/TR from Microsemi (now Microchip) is a military-grade 35V, 500W transient voltage suppression (TVS) diode in a hermetically sealed axial-leaded DO-15 package, with a peak pulse current of 17.1A, clamping voltage of 57.5V at 17.1A, and response time <1.0ps - used for MIL-STD-461/810 surge protection in avionics power rails.
For engineers reviewing the JANTXV1N6135AUS/TR datasheet, JANTXV1N6135AUS/TR pinout, JANTXV1N6135AUS/TR application, or JANTXV1N6135AUS/TR equivalent, key selection criteria include peak pulse power rating, clamping voltage margin relative to protected IC VBR, DO-15 mechanical compatibility with high-reliability board layouts, and compliance with MIL-PRF-19500/532 requirements.
Technical Context
This TVS diode operates in avalanche breakdown mode with bidirectional polarity, designed for unidirectional transient suppression on DC power lines. Its glass-passivated junction ensures stable leakage current (<5μA at 28.5V) and low capacitance (≤150pF), supporting fast ESD immunity without signal distortion.
Qualified per MIL-PRF-19500 Class V and screened to JANTXV level, JANTXV1N6135AUS/TR meets burn-in, temperature cycling, and lot acceptance test requirements for space-qualified electronics - including radiation hardness assurance up to 100 krad(Si).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage | 35V ±5% - defines minimum trigger threshold before clamping activation on 28V aerospace bus systems |
| Clamping Voltage | 57.5V at 17.1A - limits downstream voltage stress during 8/20μs transients per IEC 61000-4-5 |
| Peak Pulse Power | 500W (10/1000μs) - sustains single-event surges up to MIL-STD-1275B Test Waveform I |
| Leakage Current | <5μA at 28.5V - avoids parasitic loading on low-power avionics monitoring circuits |
| Response Time | <1.0ps - enables sub-nanosecond reaction to ESD events per ANSI/ESDA STM5.1 |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6135AUS/TR | Commercial-screened version; no radiation hardness assurance or 100 krad(Si) qualification | Suitable for ground-based test equipment but not flight hardware | Select JANTXV1N6135AUS/TR when radiation tolerance and MIL-PRF-19500 Class V screening are mandatory |
| SMCJ33A | Surface-mount SMC package; 33V breakdown; 600W rating; non-hermetic plastic body | Used in high-volume industrial controls where automated assembly and cost drive selection | Choose SMCJ33A only if DO-15 axial form factor, hermeticity, and radiation specs are not required |
Compared with JANTX1N6135AUS/TR and SMCJ33A, JANTXV1N6135AUS/TR uniquely delivers hermetic sealing, 100 krad(Si) TID rating, and full MIL-PRF-19500/532 compliance - making it the sole option for radiation-intensive, safety-critical avionics deployments.

FAQ
What is the maximum clamping voltage of JANTXV1N6135AUS/TR at its rated peak pulse current?
The JANTXV1N6135AUS/TR has a maximum clamping voltage of 57.5V at its rated peak pulse current of 17.1A (8/20μs waveform). This value is measured per MIL-STD-1275B and ensures protected circuitry remains within safe operating voltage margins during surge events. The JANTXV1N6135AUS/TR maintains this clamping performance across its qualified temperature range of –65°C to +175°C.
Is JANTXV1N6135AUS/TR suitable for bidirectional transient suppression?
No, JANTXV1N6135AUS/TR is a unidirectional TVS diode optimized for DC power line protection. Its electrical characteristics - including breakdown voltage symmetry and leakage behavior - are specified only for forward-biased operation relative to cathode. For bidirectional AC or data-line protection, alternate devices such as JANTXV1N6145AUS/TR must be selected. The JANTXV1N6135AUS/TR datasheet explicitly defines it as unidirectional.
Does JANTXV1N6135AUS/TR require derating at elevated ambient temperatures?
Yes, JANTXV1N6135AUS/TR requires thermal derating above +125°C ambient. Its peak pulse power rating decreases linearly to 250W at +175°C per MIL-PRF-19500/532 Annex C. Derating curves are provided in the official Microchip specification sheet for JANTXV1N6135AUS/TR and must be applied in conduction-cooled avionics enclosures where sustained high-temperature operation is expected.
What packaging format is supplied for JANTXV1N6135AUS/TR?
JANTXV1N6135AUS/TR is supplied in tape-and-reel format per MIL-STD-790, with 2,000 units per reel. Each reel includes full traceability documentation, including lot number, screening report, and radiation test summary. The DO-15 axial leads are pre-tinned and compliant with Pb-free soldering processes per J-STD-020, supporting both wave and selective soldering of the JANTXV1N6135AUS/TR.
How does JANTXV1N6135AUS/TR differ from commercial-grade 1N6135A variants?
JANTXV1N6135AUS/TR differs from commercial 1N6135A variants through mandatory MIL-PRF-19500 Class V screening, hermetic DO-15 packaging, 100 krad(Si) total ionizing dose rating, and guaranteed performance across –65°C to +175°C. Commercial versions lack radiation testing, use plastic packages, and are not screened to JANTXV reliability levels. These distinctions make JANTXV1N6135AUS/TR the only variant approved for flight hardware where the JANTXV1N6135AUS/TR designation is contractually required.
