By connecting collector to base, you get a *lower* forward voltage drop than with a simple diode.
Example: germanium diode-connected transistor has a drop of about 0.13 volts, rectifier diode about 0.3 (over 2.5 times)
It's just that rectifiers are optimised for rectification, are designed to work at (generally) higher currents, and are cheaper.

∙ 12y agoWhat do you mean? A diode is used to control direction of power flow; transistors are used to create logic circuits (NOR, NAND, OR, AND, XOR, XNOR, etc.). Generally it is better to use a diode for jobs diodes are better at than transistors because they are physically smaller.

Can fet be used as a transisitors?
No. The Field Effect Transistor is a different technology than the Bipolar Junction Transistor. That cannot substitute for one another.
How can we Diode can be used as a rectifier?
A diode is used to stop the negative voltage swing in an AC signal, so you only get the positive portions.diode-rectifier
What type of rectifier used in radar?
the usual semiconductor rectifier used in the microwave band is a gunn diode. Vacuum tube diodes are sometimes used too.
What does 4007 represents in 1n4007 transistor?
A 1n4007 is a diode and not a transistor, the 4007 don't really represent anything, the 1n4007 is a axial lead standard recovery rectifier, working peak reverse voltage = 1000V, the forward current for this device = 1 Amp. More data about it can be find in the data sheet.
What are metalloids in transistor radios used for?
The metalloids is combined in transistor radios to make them of high quality.
Is transistor a rectifier?
there are two diodes there but to use them as rectifiers never
Can the two end of a center tap transformer be use with out a rectifier?
The twoends of a center tap transformer cannot be used without a rectifier.
Is BT169 a npn or pnp transistor?
BT169 is neither an NPN nor a PNP transistor. BT169 is a thyristor, otherwise known as a silicon controlled rectifier.
Can fet be used as a transisitors?
No. The Field Effect Transistor is a different technology than the Bipolar Junction Transistor. That cannot substitute for one another.
What is the effect of inductive load on a single phase full wave bridge rectifier?
rectifier is used to resist the current likewise in bridge wave rectifier ,the inductive load is used to resist high amount of current because in bridge wave we cannot resist the current by using rectifier ..so we are using inductive load here
Why we you use center tapping in rectifier?
because we can get two different value at outpit.if we cosider tree point at secondery side of rectifier of 100volt that is A,B and C than we can get 50 vol bitween A and C.and we can get 100 volt bitween A and B.so no need to use two different value rectifier of 50 and 100 valt
Can you make transistor with 2 diode?
Yes, if the transformer output is center-tapped; otherwise, no, a bridge rectifier requires four diodes, or six for three phase power. More technically correct, what we are talking about is a full-wave rectifier. A bridge rectifier is properly always four or six diodes.
Is it true a transistor changes alternating current into direct current?
Not usually. A transistor is an amplifier, that can be used as a switch. If set up correctly it can be used to rectify AC current (i.e. convert it into DC), however it will need a capacitor to smooth the DC current (i.e. keep the voltage constant or nearly the same). What is typically used is a rectifier, a small circuit consisting of one or more diodes.
Can diode be used as rectifier?
yes ofcourse diode can be used as rectifier but it's an uncontrolled rectification.
Can you use transistor as a rectifier?
No, a Transistor operates with a modulated direct current. You need 4 Diodes to manufacture a rectifier to deliver direct current at the outlet, with alternating current at the input. A Diode is effectively a one way valve to address one halve of the cycle of the alternating current.
What is single phase Controlled rectifier?
such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
