Overview
The BAV21W is a surface-mount switching diode housed in an SOD-123 plastic-encapsulated package. It features a peak repetitive reverse voltage of 200 V and an average rectified output current rating of 200 mA. The device exhibits a maximum reverse current of 0.1 µA at 200 V, a forward voltage drop up to 1.25 V at 200 mA, and a total capacitance of 5 pF. Its reverse recovery time is specified at 50 ns, supporting fast switching applications with a power dissipation capacity of 500 mW.
Feature Summary
- Low reverse current for efficient isolation
- Fast switching speed suitable for high-frequency circuits
- Surface mount package designed for automatic insertion
Applications
- General purpose switching applications
- High-speed signal routing
- Clamping and protection circuits
Procurement Notes
Verify the component marking code T3 against the datasheet to confirm the BAV21W variant. Ensure the supplier provides documentation confirming the SOD-123 package type and green molding compound status if required. Cross-reference the 200 V reverse voltage rating with circuit requirements before procurement.
Selection Notes
Select this component when a 200 V reverse voltage rating is necessary for general-purpose switching. The SOD-123 package offers space efficiency compared to larger through-hole alternatives. Consider the 50 ns reverse recovery time for high-speed digital or RF applications requiring fast transition times.
Part Context
The BAV21W belongs to the BAV19W~BAV21W series of switching diodes manufactured by GM Semi. These components are designed as low-cost, high-reliability solutions for general-purpose electronic circuits. The series shares identical physical packaging and thermal characteristics while differing primarily in their reverse voltage breakdown specifications.
Replacement Considerations
BAV19W and BAV20W are compatible within the same series but offer lower reverse voltage ratings of 120 V and 150 V respectively. Verify that the application voltage does not exceed the replacement part's maximum repetitive reverse voltage specification.
