The recommended soldering temperature for the BR34 is between 250°C to 260°C for a maximum of 2 seconds.
While the BR34 is suitable for general-purpose rectification, it's not recommended for high-frequency applications (>1 kHz) due to its relatively high reverse recovery time (trr) of 3 μs.
To ensure proper derating, follow the temperature derating curve provided in the datasheet. As a general rule, reduce the maximum average forward current (IF(AV)) by 1.5 mA/°C above 25°C.
Store the BR34 in a dry, cool place with a relative humidity of 60% or less. Avoid exposing the device to temperatures above 30°C or humidity above 80% for extended periods.
Yes, the BR34 can be used in parallel to increase the current rating, but ensure that each device has its own separate heat sink and that the current sharing is balanced to prevent overheating.
