MMBD1703A

Overview

The MMBD1703A is a small signal diode from the MMBD1700 series, manufactured by onsemi. It features a maximum repetitive reverse voltage of 30 V and an average rectified forward current of 50 mA. The device supports a non-repetitive peak forward surge current of 250 mA with a pulse width of 1.0 second. Electrical characteristics include a breakdown voltage of 30 V at 5.0 µA reverse current, a total capacitance of 1.0 pF at 0 V reverse bias and 1.0 MHz, and a reverse recovery time ranging from 0.7 to 1.0 ns under specified test conditions.

Feature Summary

• High-speed switching capability with low reverse recovery time
• Low total capacitance for high-frequency applications
• Dual configuration in a compact SOT-23 package

Applications

• General purpose switching circuits
• Signal processing applications
• Clamping and protection circuits

Procurement Notes

Verify the manufacturer origin carefully, as the MMBD1700 series was originally developed by Fairchild Semiconductor. Ensure the specific revision (Rev. B1) matches design requirements. Confirm RoHS compliance status through official documentation before integration. Check for any obsolescence notices or lifecycle changes that may affect long-term supply stability.

Selection Notes

Select this component when a fast-switching diode with low capacitance is required in a small surface-mount package. The 30 V rating suits low-voltage signal paths. Compare performance against higher voltage variants like the MMBD1404A if system voltages exceed 30 V. Consider thermal derating curves for ambient temperature constraints.

Part Context

This part belongs to the MMBD1700 series of small signal diodes. The series includes variants such as MMBD1701, MMBD1703, MMBD1704, and MMBD1705, along with their 'A' suffix versions. These devices are designed for general-purpose switching and clamping applications in consumer electronics and industrial control systems.

Replacement Considerations

Direct substitutes within the same series include MMBD1701A, MMBD1704A, and MMBD1705A. Verify pinout compatibility and electrical parameters match exactly. Cross-reference with other manufacturers' equivalents only after confirming all absolute maximum ratings and dynamic characteristics align.
