BAV20-TR

Single Diodes Overview

The BAV20-TR is a small signal switching diode from Vishay Semiconductors, fabricated using silicon epitaxial planar technology. It features a hermetically sealed leaded glass DO-35 (DO-204AH) package with a black cathode band. The device supports a repetitive peak reverse voltage of 200 V and a continuous forward current of 250 mA. Key electrical characteristics include a maximum reverse recovery time of 50 ns, a typical forward voltage of 1 V at 100 mA, and a diode capacitance of 1.5 pF at 0 V and 1 MHz. It operates within a temperature range of -65 °C to +175 °C.

Single Diodes Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm packaging options such as tape and reel or ammopack configurations. Ensure that the component selection aligns with the required thermal resistance and junction temperature limits for the intended operating environment. Cross-reference the absolute maximum ratings with system constraints to prevent exceeding the specified power dissipation and surge current thresholds during operation.

Single Diodes Selection Notes

Select this component when high-voltage switching capabilities are required in a through-hole configuration. The 200 V repetitive peak reverse voltage rating distinguishes it from lower voltage variants within the same family. Consider the 50 ns reverse recovery time for applications demanding fast switching performance. Verify compatibility with the DO-35 footprint and ensure the operating temperature range meets the environmental requirements of the target assembly.

Single Diodes Part Context

This part belongs to the BAV17/BAV18/BAV19/BAV20/BAV21 series of small signal switching diodes. All members share identical physical packages and general structural features but differ in their reverse voltage ratings. The BAV20 specifically provides a 200 V rating, positioning it between the BAV19 (120 V) and BAV21 (250 V) variants for medium-to-high voltage switching tasks.

Single Diodes Replacement Considerations

Direct substitutes within the same series include BAV17, BAV18, BAV19, and BAV21, provided the voltage rating differences are acceptable for the circuit design. Other generic DO-35 packaged silicon switching diodes with comparable electrical specifications may serve as alternatives if pinout and thermal characteristics match.
