Overview
The MMBD1503A is a small signal diode manufactured by onsemi, housed in an SOT-23 (TO-236) package. It features a maximum repetitive reverse voltage of 200 V and an average rectified forward current of 200 mA. The device supports a non-repetitive peak forward surge current of up to 2.0 A for short pulses. Electrical characteristics include a breakdown voltage of 200 V at 5.0 µA reverse current, with a forward voltage ranging from 620 mV to 720 mV at 1.0 mA. Total capacitance is specified at 4.0 pF under zero bias conditions.
Feature Summary
- High voltage capability suitable for general-purpose switching applications
- Low total capacitance for high-frequency signal integrity
- Robust thermal performance with junction temperature ratings up to +150 °C
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 ensure correct shipping configuration and marking codes. Confirm that the component meets all required environmental compliance standards for the intended deployment environment before finalizing procurement decisions.
Selection Notes
Select this component when a compact silicon diode with high reverse voltage tolerance is required. Ensure the application current remains within the 200 mA average limit and verify that the operating temperature stays within the specified -55 °C to +150 °C range for reliable operation.
