SRF2090H

Diode Arrays Overview

The SRF2090H is a dual Schottky rectifier manufactured by Taiwan Semiconductor. It features a common cathode configuration with two silicon elements housed in an ITO-220AA (TO-220AB) through-hole package. The device supports a maximum average forward rectified current of 10A per leg and withstands a repetitive peak reverse voltage of 90V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 200A, a maximum DC reverse leakage current of 300uA at rated voltage, and a maximum forward voltage drop of 0.92V at full load. It operates within a junction temperature range of -55°C to +150°C.

Diode Arrays Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and packaging variations. Ensure component authenticity through authorized channels. Confirm RoHS compliance status matches project requirements. Validate thermal management capabilities align with system heat dissipation limits before integration.

Diode Arrays Selection Notes

Select this component for applications requiring low forward voltage and high surge current handling. Compare thermal resistance values against available heatsinking options. Ensure the 90V reverse voltage rating exceeds peak circuit voltages with adequate margin. Consider the through-hole mounting style for mechanical robustness in vibration-prone environments.

Diode Arrays Part Context

This part belongs to the SRF series of Schottky rectifiers from Taiwan Semiconductor. It complements other variants like the SRS2090HRNG which uses a surface-mount D2PAK package. The series targets general-purpose power rectification where efficiency and reliability are prioritized over minimal footprint size.

Diode Arrays Replacement Considerations

Cross-reference with SBCT2090 from Diotec Semiconductor for similar specifications. Verify pin compatibility and thermal performance when substituting. Ensure voltage and current ratings meet or exceed original design requirements.
