MMBD1504

Overview

The MMBD1504A is a small signal switching diode manufactured by onsemi, 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 non-repetitive peak forward surge current capability of up to 2.0 A for short pulses. Electrical characteristics include a maximum forward voltage of 1.10 V at 200 mA and a total capacitance of 4.0 pF at 0 V reverse bias. Thermal resistance from junction to ambient is rated at 357 °C/W.

Feature Summary

• High voltage general-purpose switching capability with a 200 V breakdown rating
• Low parasitic capacitance suitable for high-speed signal applications
• Robust thermal performance allowing operation up to a 150 °C junction temperature

Applications

• General purpose signal switching circuits
• Protection against transient voltages in electronic interfaces
• Clamping and steering functions in low-power logic systems

Procurement Notes

Verify the specific ordering suffix when sourcing components, as variations such as D87Z or NSV prefixes indicate different packaging formats or automotive qualification standards. Confirm that the received part matches the exact data sheet revision and marking code to ensure compliance with the specified electrical limits and physical dimensions.

Selection Notes

Select this component for designs requiring a compact surface-mount solution with high reverse voltage tolerance. Ensure the application current remains within the 200 mA average limit and verify that the operating environment stays within the specified -55 °C to +150 °C temperature range for reliable long-term performance.

Part Context

This device belongs to the MMBD15 series of small signal diodes produced by onsemi. The series includes variants like MMBD1501A and MMBD1503A, which share similar packaging and fundamental switching characteristics but differ in specific internal configurations or marking codes.
