Overview
The BAV21-T50A is a general-purpose switching diode manufactured by NXP Semiconductors. It is fabricated using planar technology and encapsulated in a hermetically sealed leaded glass SOD27 (DO-35) package. The device features a maximum repetitive peak reverse voltage of 250 V and a maximum average forward rectified current of 200 mA. It is designed for high-voltage applications requiring fast switching characteristics.
Feature Summary
- High voltage capability with 250 V reverse voltage rating
- Fast switching performance suitable for general-purpose applications
- Hermetically sealed leaded glass package for reliability
Applications
- General purpose switching circuits
- High voltage signal processing
- Clamping and protection applications
Procurement Notes
Verify the specific ordering suffix T50A to confirm the tape and reel packaging quantity and variant details. Ensure the DO-35 package style matches the design requirements. Confirm the manufacturer source is NXP Semiconductors or an authorized distributor like Nexperia, as part numbers may be shared across entities. Check for any specific handling instructions related to the hermetically sealed glass construction.
Selection Notes
Select this component when a robust, high-voltage switching diode is required in a through-hole DO-35 package. The 250 V rating provides significant headroom for standard logic and power supply lines. Consider the 200 mA current limit for load requirements. The planar technology ensures consistent electrical characteristics across temperature ranges.
Part Context
This diode belongs to the BAV20/BAV21 series of general-purpose switching diodes. These components are widely used in consumer electronics, industrial controls, and automotive systems where reliable high-voltage isolation and fast switching are necessary. The DO-35 package offers a compact footprint for through-hole mounting.
Replacement Considerations
Direct substitutes include the BAV20 variant if lower voltage ratings are acceptable. Verify pinout compatibility and thermal characteristics before substitution. Other manufacturers producing equivalent DO-35 silicon switching diodes with similar 250 V / 200 mA ratings may serve as alternatives.
