Both devices achieve a typical transition frequency (ft) of 30MHz. Another advantage is the high linearity of hFE and also VBE. The 2SA1943N transistor enables a minimum DC Current Gain, hFE (1) of 80 (VCE = -5V and IC = -1A) and hFE (2) of 35 (VCE = -5V and IC = -7A), while the 2SC5200N hFE (1) of 80 (VCE = 5V and IC = 1A) and hFE (2) of 35 (VCE = 5V and IC = 7A). The 2SA1943N transistor has a maximum collector-emitter voltage rating of (VCEO) of -230V and continuous collector current rating (IC) of -15A, while the 2SC5200N has a maximum VCEO of 230V and an IC of 15A. This provides product designers with greater flexibility, whilst maintaining package power (Pc) at 150W.
The new 2SA1943N and 2SC5200N provide the same high quality sound output as the now-famous 2SA1943 and 2SC5200 but in a TO-3P(N) package and just three quarters of the width and length to reduce space consumption compared to the previous TO-3P(L) package.

When the transistor is and saturation the collector to emitter voltage is?Įxplanation: At saturation, the collector-to-emitter voltage is the minimum drop possible occurring due to the non-zero internal resistance of the BJT. Saturation Region In the saturation or linear region, the transistor will be biased so that the maximum amount of gate voltage is applied to the device which results in the channel resistance RDS(on being as small as possible with maximum drain current flowing through the MOSFET switch. Note also that the base-emitter junction is evident, acting like the diode that is actually is. In figure 5, this implies Vout is almost 0 volts, but actually about 0.2 volts. In saturation, the transistor appears as a near short circuit between the collector and emitter terminals. When the transistor is in saturation the collector to emitter voltage is? When in saturation, the current may be high, but Vce is very small, keeping the power dissipated by the transistor very low. When in cutoff, there is no current flow between collector and emitter thus P = Vce ∗ Ic = 0. When the transistor is either in saturation or cutoff modes, it dissipates little power. Saturation voltage, collector-emitter (VCE(sat)) The voltage between the collector and emitter terminals under conditions of base current or base-emitter voltage beyond which the collector current remains essentially constant as the base current or voltage is increased.
How is VCE saturation calculated?ĭetermine the voltage drop between the collector and emitter junctions (Vce) of the transistor using the formula Vce = Vcc – IcRc, where “Vce” is the collector emitter voltage “Vcc” is the supply voltage and “IcRc” is the voltage drop across the base resistor (Rb). A bipolar transistor becomes saturated when the base-emitter current reaches a maximum under conditions of changing bias. The term is used especially in applications involving diodes and bipolar transistor s. Saturation is the fully conducting state in a semiconductor junction. Since it cannot decrease further, the current IC cannot increase further. What is the collector to emitter voltage in saturation Mcq?Įxplanation: At saturation, the collector-to-emitter voltage is the minimum drop possible occurring due to the non-zero internal resistance of the BJT.
