MMBD1202

Single Diodes Overview

The MMBD1202 is a small signal diode manufactured by onsemi, housed in a surface-mount SOT-23 package. It features a maximum repetitive reverse voltage of 100 V and an average rectified forward current rating of 200 mA. The device supports a non-repetitive peak forward surge current up to 2.0 A for microsecond pulses. Electrical characteristics include a maximum forward voltage of 1.0 V at 200 mA and a total capacitance of 2.0 pF at 1.0 MHz. Thermal performance specifies a junction-to-ambient resistance of 357 °C/W with a maximum operating junction temperature of 150 °C.

Single Diodes Procurement Notes

Verify the specific part number against official manufacturer databases to confirm current production status and availability. Ensure that sourcing channels are authorized distributors to guarantee component authenticity and traceability. Review the datasheet for absolute maximum ratings prior to integration to prevent overstress conditions during operation.

Single Diodes Selection Notes

Select this component when a dual-diode solution is required in a minimal surface-mount form factor. Evaluate the 100 V reverse voltage rating against circuit peak inverse voltages. Consider the thermal resistance and power dissipation limits relative to the expected ambient temperature and forward current loads in the target application design.

Single Diodes Part Context

This device belongs to the MMBD120x series of small signal diodes from onsemi, formerly Fairchild Semiconductor. The series includes variants such as MMBD1201 through MMBD1205, which share similar electrical specifications but may differ in internal connection topologies or pin configurations. These components are designed for general-purpose switching and rectification tasks in consumer and industrial electronics.

Single Diodes Replacement Considerations

Consult the official datasheet for the MMBD120x series to identify compatible substitutes with identical pinouts and electrical ratings. Verify that any alternative component matches the SOT-23 package dimensions and thermal characteristics to ensure mechanical fit and reliable performance.
