FUNCTION PATH

How VUB116-16NOXT forms an inverter front end

A power path from three-phase rectification through DC-link braking, temperature sensing and heatsink transfer.

Rectify

Convert the three-phase AC input into the inverter DC-link supply through the diode bridge.

AC TO DC

Brake

Switch regenerative DC-link energy through the integrated 1200 V brake IGBT.

CHOPPER

Sense

Measure module temperature through the embedded NTC for supervisory protection.

THERMAL INPUT

Cool

Transfer semiconductor losses through the DCB-isolated copper base into the designed heatsink.

HEAT FLOW

APPLICATION 01

Variable-frequency drives

For integrated rectifier and brake front ends in industrial motor inverters.

APPLICATION 02

Compact DC-link assemblies

For PCB-mounted power stages that benefit from combined rectifier, IGBT, diode and NTC functions.

APPLICATION 03

Thermally supervised converters

For power electronics where temperature feedback is included in the protection strategy.

BUYER GUIDANCE

VUB116-16NOXT questions answered

Selection, integration, lifecycle and quotation guidance written for practical purchasing decisions.

Which power functions are integrated in Littelfuse IXYS VUB116-16NOXT?

The module combines a three-phase rectifier bridge, a brake IGBT, a brake diode and an NTC temperature sensor in one E2-Pack.

Which voltage domains define Littelfuse IXYS VUB116-16NOXT selection?

The rectifier has a 1600 V repetitive reverse rating, while the brake IGBT and diode use a 1200 V class. The actual circuit must remain within every static and dynamic limit.

How must Littelfuse IXYS VUB116-16NOXT be thermally integrated?

Use the official junction-to-case data, mounting recommendations, DCB-isolated base and application loss calculation to size the heatsink and interface material.

What role does the NTC play inside Littelfuse IXYS VUB116-16NOXT?

The integrated NTC provides a temperature-dependent resistance signal that can support converter monitoring, protection and thermal derating logic.

Which mechanical checks matter when replacing Littelfuse IXYS VUB116-16NOXT?

Confirm the E2-Pack outline, pin map, PCB hole pattern, 17 mm height, base flatness, mounting torque, creepage and air-clearance requirements.

How can a buyer confirm the exact Littelfuse IXYS VUB116-16NOXT being quoted?

Request clear marking and pin-side photos, quantity, date code, condition, destination and the official data sheet revision; the standard ordering code is 510755.

PEOPLE BEHIND THE PROCESS

Professional Team

Experienced judgment and patient communication support clearer automation purchasing decisions.

TEAM EXPERIENCE

Nearly 10 Years of Industry Experience

Our team members have an average of more than 10 years of industry experience. We have worked with customers worldwide, including those from India, Germany, Sweden, Italy, Russia, Venezuela, Israel, and many other countries. Throughout our careers, we have collectively completed over 3,000 orders and established long-term business relationships with customers across nearly 30 countries.

WORKING PRINCIPLEIdentify, verify and communicate.

We review model details, clarify condition and keep each purchasing step documented.

PRODUCT REVIEW

Professional Product Judgment

We can often identify a product’s manufacturer, series, configuration, and function from its model number or nameplate photo. We also understand how revisions, firmware, and specifications affect compatibility and whether an alternative model can be used safely.

In Practice

An Indian customer urgently needed a discontinued control module after several suppliers reported no stock. We identified its exact revision and function from the nameplate, checked compatible alternatives, and contacted factory and warehouse channels to locate matching inventory. After installation, the customer confirmed that the module operated correctly and later asked us to source additional spare parts.

CLEAR COMMUNICATION

Sincere and Patient Service

Our team treats every inquiry sincerely and answers every question patiently. Even for complex requests, we verify and respond to each detail instead of providing a rushed or uncertain answer.

In Practice

A German customer sent a mixed list of automation products and asked repeated questions about revisions, condition, photos, and delivery. Our team organized the requirements, checked every item, and replied point by point. The customer said our detailed communication made the purchasing decision easier and continued sending us new inquiries.
