MMBD1504A

Overview

The onsemi MMBD1504A is a small signal switching diode housed in an SOT-23 (TO-236) surface-mount package. It features a maximum repetitive reverse voltage of 200 V and supports an average rectified forward current of 200 mA. The device exhibits a low reverse leakage current of 1.0 nA at 125 V and 10.0 nA at 180 V, with a total capacitance of 4.0 pF at 0 V bias. Operating junction temperatures range from -55 °C to +150 °C.

Feature Summary

• High-voltage capability for general-purpose switching applications
• Low reverse leakage current for improved circuit isolation
• Compact SOT-23 surface-mount footprint for space-constrained designs

Applications

• General-purpose signal switching circuits
• Voltage clamping and protection stages
• Logic level shifting interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and shipping quantity. Confirm RoHS compliance status and any automotive qualification prefixes if required by the design specifications. Ensure the component matches the exact data sheet revision for accurate electrical parameter validation.

Selection Notes

Select this component when a high-voltage rating of 200 V is required in a compact SOT-23 package. The low reverse leakage and capacitance make it suitable for precision switching tasks. Compare performance against other members of the MMBD150xA family based on specific leakage or speed requirements.

Part Context

This part belongs to the MMBD1501A/03A/04A/05A series of small signal diodes manufactured by onsemi. All variants share the same SOT-23 physical package and basic thermal characteristics but differ in specific electrical parameters such as leakage current and forward voltage drop.

Replacement Considerations

NSVMMBD1504ALT1G is a documented substitute within the same product family.
