Performance Characteristics

Fast recovery: 50 ns reverse recovery, ideal for quick switching circuits

Low forward voltage drop reduces power loss

Low reverse leakage ensures efficiency and reliability

High operating temperature range provides durability in harsh environments

Application Environments

Switch-mode power supplies

Adapters and chargers

Rectification in AC-DC converters

Snubber circuits for power switching

Freewheeling diodes for inductive load switching

Consumer electronics, industrial control, automotive electronics

Selection Guidelines

Confirm voltage rating exceeds your circuit’s maximum reverse voltage

Ensure average forward current fits operational current needs

Check recovery time requirement for fast switching or high-frequency circuits

Match package type (SMA/DO-214AC) with PCB layout and production process

Consider environmental ratings (RoHS, REACH, operating temperature) for compliance

Usage Considerations

Allow for adequate heat dissipation during operation

Avoid exceeding maximum ratings for voltage and current

Observe correct polarity to prevent device failure

Ensure proper soldering of SMA package for reliable connection

Store in dry environments; moisture sensitivity level is 1 (no special handling)
