OKI-78SR-12/1.0-W36-C
Overview
The OKI-78SR-12/1.0-W36-C is a high-efficiency switching regulator designed to be a direct drop-in replacement for TO-220 package 7812 linear regulators. It converts an input voltage range of 15V to 36V into a fixed 12V output at up to 1A without the need for an external heatsink or additional components. This module significantly reduces heat dissipation and power loss compared to traditional linear solutions.
Why Choose This Part
This module provides a peak efficiency of 95.3%, which minimizes thermal energy waste and allows for a compact 3-SIP form factor without a bulky heatsink. It features integrated short-circuit protection and requires no external capacitors for operation, simplifying PCB layout and reducing total BOM count.
Applications
Key Specifications
Getting Started
To use this part, simply solder it into a standard three-pin TO-220 footprint, ensuring the input voltage remains between 15V and 36V. For horizontal mounting requirements, the OKI-78SR-12/1.0-W36H-C variant should be used. Ensure adequate airflow if operating at the full 1A output near the maximum 85 degrees Celsius ambient temperature limit.
