If you place an order that has one or more items on backorder you can choose whether to have all items despatched together or to receive the items currently in stock as soon as possible. Items on backorder will be despatched when they arrive back in stock. Orders received on Saturday or Sunday will be shipped the next business day.In stock items ordered before this time will ship out the same day the order is placed.Same-day dispatch cut-off time is: 10:30pm.Items being transferred from other global warehouses may require additional time for delivery. When selecting the delivery method, orders of in-stock items will be shipped out either the same day or next business day depending on the cut-off time listed below. Submit an order before the cut-off time to shorten your delivery time.At 1 A a 0.1 \$V_\$ (Drain-Source on resistance) of MOSFETs is typically under 0.1 \$\Omega\$ and you can get devices with 10 \$m\Omega\$ or even sub 1 \$m\Omega\$.Īs switching speeds rise MOSFETs need a gate driver to charge and discharge the gate capacitance. This can be several tenths of a volt and to get it much under 0.1V usually requires a high base to collector current ratio that is undesirably high. ![]() But, for switching more than a few ~100mA, MOSFETs are usually as cheap or cheaper than functionally equivalent transistors, are easier to drive from a uC (microcontroller) as a digital switch than bipolar transistors and tend to have very significantly superior on characteristics.Īn "on" bipolar transistor exhibits a saturation voltage. MOSFETs tend to be slightly more costly at the very bottom end for "jelly bean" applications. ![]() In both cases the spread of parameters during manufacturing is such that a circuit will almost always rely on feedback to produce a given voltage or current gain. If you wish to avoid holy wars you'll need to avoid making simplistic and incomplete statements :-).
