S3B

Single Diodes Overview

The S3B is a general-purpose rectifier diode manufactured by onsemi, designed for surface-mount applications. It features a single diode configuration housed in an SMC (DO-214AB) package. The device supports a repetitive peak reverse voltage of 100 V and an average forward rectified current of 3 A. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 115 A at 8.3 ms single half-sine-wave and a reverse recovery time of 2.5 µs. The component operates within a junction temperature range of -55°C to 150°C.

Single Diodes Procurement Notes

Verify the specific ordering suffix against the official datasheet to ensure correct packaging and compliance status. Confirm that the requested variant matches the required RoHS and halogen-free specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a 100 V rating and 3 A continuous current capacity are required in a compact surface-mount form factor. Ensure the application's peak reverse voltage remains below the 100 V limit and that thermal management allows the junction temperature to stay within the 150°C maximum operating range for reliable long-term performance.

Single Diodes Part Context

This component belongs to onsemi's standard recovery diode portfolio, categorized under general-purpose rectifiers. It utilizes silicon technology and is designed for robust performance in industrial and consumer electronics. The SMC package provides a balance between current handling capability and board space efficiency compared to larger through-hole alternatives.

Single Diodes Replacement Considerations

Direct substitutes must match the 100 V reverse voltage, 3 A forward current, and SMC package outline. Verify equivalent reverse recovery time and thermal resistance parameters to ensure circuit compatibility without redesign.
