BAV21W-TP

Overview

The BAV21W-TP is a small signal switching diode manufactured by Micro Commercial Components (MCC). It features a single silicon epitaxial planar configuration in an SOD-123 surface-mount package. Key electrical parameters include a maximum repetitive peak reverse voltage of 250 V and a forward current rating of 250 mA. The device exhibits a maximum reverse leakage current of 100 nA at 200 V, a typical forward voltage of 1.25 V at 200 mA, and a reverse recovery time of 50 ns. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Utilizes silicon epitaxial planar technology for general-purpose switching applications.
• Provides high voltage blocking capability with a 250 V peak reverse voltage rating.
• Designed for surface mount assembly using the compact SOD-123 package format.

Applications

• General purpose signal switching circuits
• High voltage rectification tasks
• Protection against reverse polarity in electronic systems

Procurement Notes

Verify the specific ordering suffix to confirm compliance requirements. The standard designation implies lead-free finish and RoHS compliance. Confirm the package type matches the target PCB footprint. Ensure the thermal management design accommodates the specified operating temperature range. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and current production status.

Selection Notes

Select this component when a robust single-diode solution is required for high-voltage environments. The SOD-123 package offers a balance between current handling capacity and board space efficiency. Consider the 50 ns reverse recovery time for moderate-speed switching applications. Evaluate the 250 V reverse voltage margin against circuit transient spikes to ensure reliable operation under varying load conditions.

Part Context

This component belongs to the BAV21 series of small signal diodes produced by MCC. The series includes variants with different voltage ratings and packaging options. The BAV21W-TP specifically denotes the 250 V version in the SOD-123 form factor. It serves as a discrete replacement for integrated dual-diode configurations in simple switching roles.
