STTH1002CB

Diode Arrays Overview

The STTH1002CB is a dual ultrafast diode manufactured by STMicroelectronics, featuring two independent rectifiers within a single package. It is rated for a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 8 A per section (10 A total). The device exhibits a low forward voltage drop of 1.25 V at 10 A and a fast reverse recovery time of 35 ns. Designed for high-frequency applications, it supports junction temperatures up to 175 °C and offers low leakage current characteristics suitable for efficient power conversion.

Diode Arrays Procurement Notes

Verify the specific suffix 'CB' corresponds to the desired package type, typically DPAK or D²PAK, as packaging variations exist within the STTH1002 family. Confirm that the 200 V rating and 8 A per section current capacity align with your circuit requirements. Ensure compatibility with surface mount assembly processes if using the DPAK variant. Cross-reference datasheets from authorized distributors to confirm RoHS compliance status for the specific manufacturing batch.

Diode Arrays Selection Notes

Select this component when designing circuits requiring dual rectification in a compact footprint. It is appropriate for applications demanding faster switching speeds than standard rectifiers but where Schottky diodes may lack sufficient reverse voltage blocking capability. Consider the thermal management requirements associated with the 1.25 V forward drop at full load. Evaluate the trade-off between the 35 ns reverse recovery time and potential electromagnetic interference compared to slower devices.

Diode Arrays Part Context

The STTH1002 series belongs to STMicroelectronics' range of ultrafast recovery diodes designed for efficiency in power electronics. This specific part integrates two diodes, simplifying board layout for center-tapped configurations. It complements other STTH variants like the STTH1002C which may offer different package options such as TO-220AB. The series targets modern power supplies where size and switching speed are critical performance factors.

Diode Arrays Replacement Considerations

Check for direct equivalents such as the STTH1002C if package flexibility allows. Verify pinout compatibility before substituting with generic dual ultrafast diodes. Ensure replacement parts meet the same 200 V reverse voltage and 8 A current ratings. Confirm that alternative components maintain similar reverse recovery times to preserve circuit timing and efficiency.
