MMBD1703WP

Overview

The MMBD1703WP is a general-purpose diode array manufactured by onsemi. It features two independent diodes connected in series within a single SOT-23 (TO-236) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 30 V and a continuous forward current of 50 mA. It is designed for high-speed switching applications with a typical reverse recovery time of 4 ns. The component operates reliably across an extended temperature range from -55°C to +150°C junction temperature, ensuring stability in demanding electronic circuits.

Feature Summary

• Dual diode configuration integrated into a compact surface-mount package
• High-speed switching capability with fast reverse recovery characteristics
• Extended thermal operating range suitable for harsh environments

Applications

• General-purpose signal rectification
• Clamping and protection circuits
• Logic level shifting interfaces

Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm package type and tape-and-reel specifications. Ensure compliance with RoHS directives and AEC-Q100 automotive qualification requirements if applicable to the target application environment. Cross-reference manufacturer part numbers to avoid counterfeit components during sourcing.

Selection Notes

Select this component when space-constrained designs require dual diode functionality in a small footprint. Consider the 30 V reverse voltage limit and 50 mA forward current rating to ensure adequate margin for circuit operation. Evaluate the 4 ns recovery time against switching frequency requirements to minimize power loss and signal distortion in high-speed digital or analog paths.

Part Context

This diode array belongs to onsemi's MMBD series of small-signal switching diodes. These devices are engineered for use in consumer electronics, telecommunications, and industrial control systems where reliable rectification and signal processing are required. The series emphasizes miniaturization and performance consistency across various manufacturing batches.

Replacement Considerations

Consult official substitution guides for compatible equivalents. Verify pinout compatibility and electrical parameter alignment before integrating alternative suppliers' parts into existing designs.
