Overview
The RB085T-40HZC9 is a Schottky barrier diode manufactured by ROHM Semiconductor, designed for high-reliability applications. It features a dual anode common cathode configuration housed in a TO-220FN (3-pin) package. The device supports a maximum repetitive reverse voltage of 40V and an average rectified forward current of 10A. Key electrical characteristics include a maximum forward voltage of 0.55V at 5A and a maximum reverse current of 0.15mA at 40V. It operates within a junction temperature range up to +150°C and complies with AEC-Q101 automotive standards.
Feature Summary
- Dual anode common cathode configuration for flexible circuit integration
- Low reverse current design ensuring high reliability
- Automotive grade qualification compliant with AEC-Q101 standards
Applications
- Automotive power supply circuits
- DC-DC converter output rectification
- Free-wheeling diodes in motor control systems
Procurement Notes
Verify the specific suffix HZC9 against official ROHM documentation to confirm packaging details and compliance status. Confirm availability as this series may be designated for existing customers only. Ensure the procurement channel provides valid traceability for automotive-grade components. Check for RoHS compliance declarations in the latest datasheet revision before finalizing orders.
Selection Notes
Select this component when a low forward voltage drop and high surge current capability are required in a through-hole package. The common cathode arrangement simplifies bridge or synchronous rectifier designs. Verify that the 40V rating aligns with the system's peak inverse voltage requirements. Consider thermal management solutions given the 10A continuous current rating and TO-220FN package constraints.
Part Context
This part belongs to the RB085T series of Schottky barrier diodes from ROHM. The series is characterized by low leakage current and robust construction suitable for demanding environments. The RB085T-40HZC9 specifically denotes the 40V variant with automotive qualification and tube packaging. It serves as a high-efficiency replacement for standard silicon rectifiers in low-voltage, high-current applications.
Replacement Considerations
Direct substitutes include other ROHM RB085T variants with matching voltage ratings such as RB085T-60NZ or RB085T-90HZ, provided the reverse voltage margin is sufficient. Cross-manufacturer replacements must match the TO-220FN footprint, 10A current rating, and common cathode configuration. Verify AEC-Q101 compliance if the application requires automotive certification.
