Overview
The RB706D-40T146 is a Schottky barrier diode manufactured by ROHM Semiconductor. It features a single configuration in an SMD/SMT surface mount package, specifically the SOT-346-3 (SMD3) housing. The device utilizes silicon technology and supports a maximum operating temperature of +125°C. Key electrical parameters include a repetitive reverse voltage (Vrrm) of 40 V, a forward current (If) of 30 mA, and a forward voltage (Vf) of 370 mV at 1 mA. The reverse current (Ir) is specified at 1 µA at 10 V, with a peak forward surge current (Ifsm) capability of 200 mA.
Feature Summary
- Low forward voltage characteristics for improved efficiency
- Low reverse leakage current for reduced power loss
- High ESD strength for enhanced reliability
- Compact plastic encapsulation suitable for space-constrained designs
Applications
- Portable electronic devices
- Mobile phones
- Computer peripherals
Procurement Notes
Verify the specific suffix T146 against official ROHM documentation to confirm the reel quantity and tape specifications. Ensure the component meets RoHS requirements if applicable to your manufacturing standards. Cross-reference the datasheet revision date to confirm the technical parameters match your design constraints before finalizing procurement.
Selection Notes
Select this component for low-voltage rectification applications requiring minimal forward voltage drop. The SOT-346-3 package is appropriate for automated surface-mount assembly processes. Consider the 40 V reverse voltage rating when designing circuits with potential voltage spikes. Verify thermal management requirements based on the 125°C junction temperature limit.
Part Context
This part belongs to the RB706 series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by low VF and low IR performance. The RB706D variant specifically denotes the single diode configuration within this family, distinct from dual or common cathode arrangements found in other series members.
Replacement Considerations
Check for direct substitutes such as the RB706F-40 or RB706W-40, noting that these may utilize different packages like SOT-323 or EMD3. Verify pinout compatibility and electrical parameter equivalence before substitution.
