The 1N4904 is a 250 V Zener designed for application in voltage regulator and reference circuits, featuring 6 V breakdown voltage, 0.3 W power dissipation, and Zener balanced temperature coefficient to ensure stable regulation over temperature cycles.
Since the 1N4904 is a Zener diode, it operates with a reverse biased junction, meaning that – unlike a normal diode – it does not conduct with a forward voltage applied. Instead, when the applied voltage reaches the breakdown voltage, it begins to conduct in the reverse direction.
The breakdown voltage of the 1N4904 is 6 V, meaning any voltage over 6 V will cause the diode to conduct. This voltage can be adjusted by changing the series resistor. With the current kept constant, a higher value resistor will lead to a higher breakdown voltage and vice versa.
Once the current passes the breakdown voltage, the voltage across the diode remains constant, even if the current is further increased. This is why Zener diodes are often used in voltage regulator and reference circuits, where a stable voltage is required.
The 1N4904 also features a relatively low 0.3 W power dissipation, reducing the need for a heatsink up to a maximum of 5 mA. Temperature stability is also controlled by a relatively low 0.2%/K zener temperature coefficient.
Overall, the 1N4904 is a robust and affordable Zener diode designed for use in voltage regulator and reference circuits. With its 6 V breakdown voltage, 0.3 W power dissipation, and Zener balanced temperature coefficient, the 1N4904 is an ideal choice for applications where stable regulation over temperature cycles is required.
