The recommended operating temperature range for DB157S-T is -40°C to 150°C, although the datasheet only specifies the storage temperature range.
To ensure reliability, it's essential to follow proper derating guidelines, use a suitable heat sink, and ensure good thermal conductivity between the device and the heat sink.
Although not specified in the datasheet, Rectron Semiconductor recommends that the surge current should not exceed 2A for a duration of 10ms or less.
Yes, DB157S-T can be used in switching regulator applications, but it's essential to ensure that the device is properly snubbed to prevent voltage spikes and ringing.
The recommended resistor value for the DB157S-T zener diode depends on the specific application and the desired zener voltage. A general rule of thumb is to choose a resistor value that limits the zener current to 10-20mA.
