Product details
Overview
JANTXV1N6108AUS/TR from Microsemi (now Microchip) is a military-grade 100 V, 500 W transient voltage suppression (TVS) diode in a hermetically sealed DO-213AB (MELF) package, with a peak pulse current of 27.8 A, clamping voltage of 170 V at 27.8 A, and response time <1.0 ps - used for protecting MIL-STD-461E/RS-105 compliant avionics power inputs.
For engineers reviewing the JANTXV1N6108AUS/TR datasheet, JANTXV1N6108AUS/TR pinout, JANTXV1N6108AUS/TR application, or JANTXV1N6108AUS/TR equivalent, key selection criteria include peak pulse power rating, clamping behavior under MIL-STD-1275B surge, low leakage (<1 µA at 80 V), and hermetic reliability for extended temperature operation (-65°C to +175°C).
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp fast-rising transients, with a standoff voltage of 100 V and maximum reverse working voltage of 80 V. Its MELF glass-passivated construction ensures stable parametric performance across thermal cycling and high-humidity environments.
Designed for compliance with MIL-PRF-19500/567 and MIL-STD-750 Method 2074, it supports surge immunity testing per MIL-STD-461E RS-105 (50 Ω/500 Ω coupling, 5 ns rise) and meets screening requirements including burn-in, temperature cycling, and hermeticity verification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 100 V - maximum continuous reverse voltage before conduction begins; sets operating margin for 28 V and 115 VAC avionics bus systems. |
| Clamping Voltage (VC) | 170 V at 27.8 A - limits transient voltage seen by downstream circuitry during 10/1000 µs surge events. |
| Peak Pulse Power (PPP) | 500 W - sustains single-event surges up to 500 W for 10/1000 µs waveform without degradation. |
| Leakage Current (IR) | <1 µA at 80 V - minimizes standby power loss and avoids false triggering in high-impedance monitoring circuits. |
| Response Time | <1.0 ps - enables protection against ESD and lightning-induced fast transients before silicon devices fail. |
| Operating Temp Range | –65°C to +175°C - qualified for engine-mounted, radar, and flight-control electronics requiring extreme thermal resilience. |
Pinout & Package
DO-213AB (MELF) hermetically sealed glass package with axial leads; no polarity marking - bidirectional device with symmetrical avalanche characteristics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode | Transient conduction path | Bidirectional terminal pair - conducts in either direction when voltage exceeds VRWM, enabling symmetric surge clamping on AC or floating DC lines. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic DO-213AB package | Eliminates moisture ingress and parametric drift over 20+ year service life in sealed avionics enclosures. |
| MIL-PRF-19500/567 qualification | Guarantees lot traceability, screening consistency, and failure rate ≤ 0.1% per 1000 hrs at 125°C. |
| Low clamping ratio (VC/VRWM = 1.7) | Provides tighter voltage margin between operating bus and clamping threshold than standard 1.8–2.2 ratios. |
| ESD immunity ≥ 30 kV (HBM) | Withstands handling and assembly ESD without parameter shift or latent damage. |
Applications
| Avionics Power Input Protection | Missile Seeker Signal Conditioning |
|---|---|
Use Scenario: 28 VDC primary power feed to flight control computers exposed to MIL-STD-704F line transients and lightning-induced surges. IC Role / Device Role / Timing Role: Primary transient suppressor placed upstream of DC-DC converters and voltage regulators. Use Value: Clamps 10/1000 µs surges to ≤170 V while maintaining <1 µA leakage to avoid regulator bias errors. | Use Scenario: Signal conditioning path for RF front-end receivers in guided munitions subject to electromagnetic pulse (EMP) events. IC Role / Device Role / Timing Role: Bidirectional TVS on differential analog sensor inputs to preserve signal integrity during EMP exposure. Use Value: Sub-nanosecond response prevents latch-up in GaAs MMIC amplifiers and preserves dynamic range under RS-105 threat profiles. |
| Tactical Radio RF Front-End | Spacecraft Power Bus Interface |
Use Scenario: Antenna port protection in manpack radios operating in contested electronic warfare environments. IC Role / Device Role / Timing Role: First-line transient suppressor on coaxial feedline interface before LNA and bandpass filtering. Use Value: Hermetic MELF construction prevents outgassing-induced noise in vacuum-compatible RF assemblies. | Use Scenario: Secondary power distribution node on 100 V bus in satellite power management units. IC Role / Device Role / Timing Role: Overvoltage clamp for battery charge/discharge regulation circuitry interfacing with solar array controllers. Use Value: Stable VRWM and VC across –65°C to +175°C ensures consistent protection during orbital thermal cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6109AUS/TR | 110 V VRWM, 185 V VC at 25.4 A, same package and screening. | Suitable for 115 VAC-derived 100 V DC bus systems with higher standoff margin. | Select when system nominal voltage exceeds 100 V but requires identical hermetic reliability and surge rating. |
| 1N6108US | Commercial-grade (non-military screened), same VRWM/VC, non-hermetic DO-213AB. | Limited to ground-based industrial controls where MIL-spec screening is not required. | Use only in non-safety-critical, non-flight applications with relaxed reliability and lifetime requirements. |
Compared with JANTXV1N6108AUS/TR, JANTXV1N6109AUS/TR offers higher standoff for elevated bus voltages, while 1N6108US sacrifices hermeticity and screening for cost reduction - neither is pin-compatible due to differing qualification levels and screening documentation, though both share identical physical form factor.

FAQ
What is the maximum clamping voltage of the JANTXV1N6108AUS/TR under a 10/1000 µs surge?
The JANTXV1N6108AUS/TR has a maximum clamping voltage (VC) of 170 V at 27.8 A for a 10/1000 µs waveform, as specified in MIL-PRF-19500/567. This value is measured under standardized surge conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The JANTXV1N6108AUS/TR maintains this clamping performance across its full operational temperature range.
Is the JANTXV1N6108AUS/TR unidirectional or bidirectional?
The JANTXV1N6108AUS/TR is a bidirectional TVS diode, with symmetrical avalanche characteristics in both forward and reverse bias. Its DO-213AB (MELF) package has no polarity marking, and it clamps transients equally on positive and negative voltage excursions. This makes the JANTXV1N6108AUS/TR suitable for AC-coupled or floating DC signal paths where polarity cannot be guaranteed.
Does the JANTXV1N6108AUS/TR require derating at elevated temperatures?
Yes - the JANTXV1N6108AUS/TR exhibits reduced peak pulse power capability above +25°C ambient, with linear derating to 50% of rated 500 W at +175°C. Derating curves are provided in the official Microsemi datasheet for JANTXV1N6108AUS/TR. Designers must apply this derating when sizing protection margins for high-temperature avionics installations.
What screening tests are performed on the JANTXV1N6108AUS/TR per MIL-PRF-19500/567?
The JANTXV1N6108AUS/TR undergoes full MIL-PRF-19500/567 screening, including steady-state life test, temperature cycling (–65°C to +175°C, 500 cycles), hermeticity (fine and gross leak per MIL-STD-883 Method 1014), and electrical parameter verification at extremes. Each lot is traceable and certified to meet failure rate Level S (0.1% per 1000 hrs).
Can the JANTXV1N6108AUS/TR replace commercial 1N6108 devices in existing designs?
No - the JANTXV1N6108AUS/TR is not a drop-in replacement for commercial 1N6108 devices due to differences in screening, hermeticity, and test documentation. While electrically similar, the JANTXV1N6108AUS/TR requires updated qualification records, lot traceability, and compliance reporting. Redesign validation per MIL-STD-750 is required before substitution in flight hardware.
