Overview
The MMBD1405A is a high-voltage general-purpose small-signal switching diode manufactured by onsemi. It features a dual common-anode configuration housed in an SOT-23-3 surface-mount package. Key electrical specifications include a peak reverse voltage of 200 V, a maximum forward current of 200 mA per diode, and a surge current rating of 2 A. The device exhibits a typical reverse recovery time of 50 ns, with a maximum forward voltage of 1.1 V at rated current and a leakage current of 100 nA. It operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Dual common-anode configuration for efficient circuit integration
- High voltage capability suitable for general-purpose switching applications
- Fast reverse recovery characteristics for signal processing
Applications
- General-purpose signal switching
- High-voltage rectification circuits
- Clamping and protection applications
Procurement Notes
Verify the specific suffix against official datasheets to confirm pinout and electrical tolerances. Ensure the component matches the required SOT-23-3 footprint and lead-free compliance standards. Cross-reference manufacturer part numbers with distributor listings to avoid counterfeit components. Confirm RoHS and REACH status for regulatory adherence in target markets.
Selection Notes
Select this component when a dual common-anode topology is required in a compact surface-mount form factor. The 200 V rating makes it suitable for higher voltage signal paths compared to standard low-voltage diodes. Consider the 50 ns recovery time for speed requirements and verify thermal management needs given the small package size and operating temperature limits.
Part Context
The MMBD1405A belongs to the MMBD14 series of small-signal switching diodes from onsemi. This series is designed for general-purpose applications requiring reliable performance in compact electronic designs. The component shares similar electrical characteristics with other variants in the family but differs in internal configuration, specifically offering a dual common-anode arrangement within a single SOT-23-3 package.
Replacement Considerations
Official substitutes include MMBD1401A, MMBD1403A, and MMBD1404A. Verify that the alternative part number matches the dual common-anode configuration and identical pinout before implementation.
