Maksimikollektoriemitterijännite

Maksimikollektoriemitterijännite, often abbreviated as Vce(max), is a crucial parameter for bipolar junction transistors (BJTs). It represents the maximum allowable voltage that can be applied between the collector and emitter terminals of the transistor while it is operating. Exceeding this voltage can lead to device breakdown, permanent damage, and unreliable performance.

This maximum voltage rating is a key specification found on a transistor's datasheet. It indicates the transistor's ability to withstand reverse bias conditions or high voltage swings without failing. The value of Vce(max) depends on various factors including the transistor's construction, doping levels, and the intended application. For instance, transistors designed for high-power or high-voltage switching applications will generally have a higher Vce(max) than those intended for low-power signal amplification.

Designers must ensure that the circuit's operating voltages never approach or exceed the specified Vce(max) to maintain the integrity and longevity of the transistor. This parameter is particularly important in switching circuits where the transistor might experience transient voltage spikes. Understanding and respecting the Vce(max) limit is fundamental for safe and effective transistor circuit design.
