Overview
The RB228NS-40TL is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for switching power supplies. It features a dual anode common cathode configuration in a TO-263S (D2PAK) surface-mount package. Key electrical parameters include a maximum repetitive reverse voltage of 40 V and an average rectified forward current of 30 A. The device exhibits a low forward voltage of 770 mV at 15 A and a maximum reverse current of 10 mA at 40 V. It supports a forward surge current of 100 A and operates at junction temperatures up to 150°C.
Feature Summary
- Ultra-low reverse leakage current optimized for switching power supply applications
- Dual anode common cathode configuration enabling efficient circuit design
- Low forward voltage drop characteristics for improved energy efficiency
Applications
- Switching power supplies
- DC-DC converters
- General-purpose rectification in electronic equipment
Procurement Notes
Verify the specific suffix TL against official datasheets to confirm tape-and-reel packaging and quantity specifications. Ensure compatibility with RoHS directives and confirm that the component meets the intended application requirements, noting that standard-grade products may not be suitable for automotive use without explicit qualification data.
Selection Notes
Select this component when a 40 V rating and 30 A continuous current are required in a D2PAK package. Consider the 770 mV forward voltage and 10 mA reverse leakage limits for thermal management. Verify that the operating temperature range up to 150°C aligns with system constraints and that the surface-mount footprint fits the PCB layout.
Part Context
This part belongs to ROHM's RB228NS series of Schottky barrier diodes. The series is characterized by ultra-low reverse current and is packaged in the TO-263S form factor. These devices are engineered for high-efficiency rectification in compact power electronics, distinguishing them from standard rectifiers through their specialized low-leakage performance.
Replacement Considerations
Direct substitutes must match the 40 V reverse voltage, 30 A forward current, and TO-263S package. Verify equivalent forward voltage and reverse leakage specifications to ensure thermal and electrical performance parity. Cross-reference manufacturer-specific pinouts and thermal pad configurations.
