Engineering Selection Recommendations

All three parts—BYG20DHM3_A/I, BYG20D-E3/TR, and BYG20D-E3/TR3—are Active product status components manufactured by Vishay General Semiconductor - Diodes Division. Each part is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Selection Basis:

The BYG20DHM3_A/I and BYG20D-E3/TR3 are both supplied in Tape & Reel (TR) packaging format. The BYG20D-E3/TR is supplied in Cut Tape (CT) & Digi-Reel® format. Selection between these parts should be based on procurement requirements and assembly line compatibility with available tape and reel handling equipment.

All three parts demonstrate identical electrical performance across all specified parameters: 200 V reverse voltage rating, 1.5 A average rectified current, 1.4 V forward voltage drop at 1.5 A, 75 ns reverse recovery time, and 1 µA reverse leakage current at 200 V. The avalanche technology classification and fast recovery speed characteristics are consistent across all options.

Inventory availability differs among the three parts: BYG20DHM3_A/I has 716 pieces in stock, BYG20D-E3/TR has 4300 pieces in stock, and BYG20D-E3/TR3 has 3190 pieces in stock. Component selection may be influenced by supply chain requirements and lead time considerations.
