Key Features
- 48 V nominal input (36 V to 75 V range) with 3.3 V regulated output at 30 A for robust intermediate bus power conversion
- 90.5% conversion efficiency reducing heat dissipation and improving system power density in 1/8-brick DC-DC modules
- Remote shutdown capability plus EN, IEC, and UL approvals enabling safe integration into regulated industrial and telecom power systems
Applications
The SQE48T30033-NDA0G is designed for intermediate bus power architecture in telecommunications equipment, data center servers, and industrial control systems where a 48 V bus must be converted to 3.3 V at up to 30 A. Its 90.5% efficiency and 1/8-brick form factor make it ideal for high-density power distribution boards requiring EN, IEC, and UL certified DC-DC modules. The remote shutdown feature adds flexibility for system-level power sequencing and protection in multi-rail designs.

Frequently Asked Questions
What is the input voltage range and output specification of the SQE48T30033-NDA0G?
The SQE48T30033-NDA0G accepts an input voltage range of 36 V to 75 V with a 48 V nominal, delivering a regulated 3.3 V output at up to 30 A. This 8-pin 1/8-brick DC-DC module is suited for 48 V bus architectures requiring stable 3.3 V rails in telecom, industrial, and data center power systems.
How does the 90.5% efficiency of SQE48T30033-NDA0G impact system thermal design?
With 90.5% conversion efficiency at its nominal 48 V input to 3.3 V at 30 A, the SQE48T30033-NDA0G dissipates approximately 10.5 W as heat under full load, minimizing thermal management requirements. This high efficiency reduces heatsink size and fan requirements in high-density 1/8-brick power module applications compared to lower-efficiency alternatives.
Which safety certifications does SQE48T30033-NDA0G carry and why does this matter for industrial designs?
The SQE48T30033-NDA0G carries EN, IEC, and UL approvals, making it suitable for regulated industrial, telecommunications, and commercial equipment requiring certified DC-DC power conversion. These certifications confirm compliance with international safety and electromagnetic standards, simplifying system-level certification when deploying the 48 V to 3.3 V 30 A module in global markets.
When should a designer choose SQE48T30033-NDA0G over a higher-output brick module for a 3.3 V rail?
A designer should choose SQE48T30033-NDA0G when the system load does not exceed 30 A on the 3.3 V rail and board real estate is constrained to the 1/8-brick footprint. For loads above 30 A, a quarter-brick or half-brick module would be more appropriate, but for 30 A or less the SQE48T30033-NDA0G provides 90.5% efficiency with remote shutdown in a compact 8-pin package.
