BAS21HT1G

Single Diodes Overview

The BAS21HT1G is a high voltage switching diode from onsemi, housed in an SOD-323 package. It features a continuous reverse voltage of 250 V and a repetitive peak reverse voltage of 250 V. The device supports a peak forward current of 200 mA and a non-repetitive peak forward surge current of 2.5 A at 60 Hz. Electrical characteristics include a maximum reverse leakage current of 100 nA at 150°C and a typical reverse recovery time of 50 ns. Diode capacitance is typically 5.0 pF at 0 V reverse bias.

Single Diodes Feature Summary

• High voltage capability with 250 V reverse voltage rating for robust switching applications
• Automotive qualification including AEC-Q101 standards and PPAP capability for specialized site requirements
• Compliant with environmental standards as Pb-Free, Halogen Free, and BFR Free

Single Diodes Applications

• Automotive electronics requiring unique site control and quality assurance
• High voltage switching circuits in consumer and industrial equipment
• General purpose rectification where compact surface-mount packaging is required

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm tape and reel specifications, as quantities vary by variant. Ensure the NSV prefix is included if automotive qualification and specific site control changes are required for your application. Confirm RoHS compliance status matches your regulatory needs. Check date code orientation variations depending on manufacturing location during receipt inspection.

Single Diodes Selection Notes

Select this component when a 250 V reverse voltage rating is necessary in a small SOD-323 footprint. Consider the thermal resistance values if operating near junction temperature limits. Verify that the 50 ns reverse recovery time meets the speed requirements of your switching frequency. Ensure the forward current ratings align with your circuit's peak load demands.

Single Diodes Part Context

This part belongs to the BAS21H series of high voltage switching diodes manufactured by onsemi. It utilizes the SOD-323 surface-mount package, designated as CASE 477. The series is designed for general-purpose applications requiring reliable performance under high reverse voltage conditions while maintaining a low profile suitable for modern PCB layouts.

Single Diodes Replacement Considerations

Datasheet lists BAS21HT3G as an alternative variant within the same package type, differing primarily in tape and reel quantity specifications.
