The MMBD2004S is a high voltage surface mount dual switching diode from Diodes Incorporated, housed in an SOT-23 package. It features a maximum repetitive peak reverse voltage of 300V and a forward continuous current rating of 225mA. The device exhibits a fast switching speed with a maximum reverse recovery time of 50ns and low leakage current of 100nA at 240V. It operates within a temperature range of -65°C to +150°C and is qualified to AEC-Q101 standards.
Verify the specific ordering suffix against official documentation to confirm packaging details and qualification status. Ensure compliance with RoHS directives and confirm moisture sensitivity levels prior to assembly. Cross-reference marking codes such as KA9 or KAE with datasheet specifications to validate authenticity and production date codes.
Select this component for designs requiring high voltage isolation in compact surface mount layouts. Evaluate thermal resistance and power dissipation limits under expected operating conditions. Consider the dual series structure for bridge configurations or polarity protection schemes where space constraints necessitate small form factors like SOT-23.
This part belongs to Diodes Incorporated's line of high voltage surface mount switching diodes. It is designed for automated insertion processes and offers lead-free plating with matte tin finish over alloy 42 leadframe. The device utilizes molded plastic green molding compound with UL flammability classification rating 94V-0.
MMBD2004SQ is the automotive-compliant variant available under a separate datasheet.
