We just came back from our CNY holiday,and we had a great holiday.^_^

Now we would like to take a monent to let you know our updated stock about diode M7 and LL4148 after CNY holiday.

Our Stock Notification:
LL4148 LL-34 T&R RoHS SPQ:2.5kpcs/reel 2kkpcs stock available
M7 DO-214AC T&R RoHS SPQ:5kpcs/reel    sold out

M7 is always best seller. Although we had sold out, but we will replenish it asap. If you still have request, pls feel free to contact us, and we will try our utmost to give you the quickest lead time. 

Pls kindly note there are only 2kkpcs LL4148 at present, and it will be sold out this month. Pls catch the last chance because our price is much more competitive with the stock available. 

Thank you for your kind attention and wait for your business cooperation soon. 

We will have a CNY holiday soon, but we have specially prepared below stock for you. Don't worry about the lead time during this period.

Pls feel free to conatct us even in CNY holiday. Our sales office will be only closed from 6th Feb to 10th Feb.

Different types of diodes have different parameters.We must understand the following main parameters:

4. Reverse Current
Diode reverse current is at a temperature and a predetermined maximum reverse voltage is applied, current flows through the diode reverse. The smaller the reverse current, the conductive performance of the tube in one direction, the better. It is noteworthy that the reverse current and temperature are closely related, the temperature is increased by about 1 0 ℃, the reverse current increases doubled. For example 2APl type germanium diode, at 25 ℃, the reverse current of 250μA, the temperature rises to 35 ℃, reverse current will rise to 500μA, at 75 ℃, its reverse current has reached 8mA, not only lost a single direction of the conductive characteristics, the tubes will overheat and damage. Than the germanium diode silicon diode has good stability at high temperatures.

5. Reverse Recovery Time
From the forward voltage becomes a reverse voltage, ideally instantaneous cut-off current can, in fact, there are generally a little time delay. Determine the amount of current cut-off delay, that is the reverse recovery time. Although it directly affects the switching speed of the diode, but not necessarily say that this value is small enough.

6. Maximum Power
Maximum power is applied across the diode voltage multiplied by the current flowing. This limit is especially important parameter for regulator diodes.
