The DL5248B-TP is a single Zener diode which is designed for usage in voltage regulating applications. This wide band gap Zener diode is designed to exhibit high stability of long-term performance, low internal capacitance and low operating current. It also provides low leakage current and fast switching time. With its wide range of operation, the DL5248B-TP is an ideal voltage regulating diode for a variety of applications.

Application Field and Working Principle of the DL5248B-TP

The primary application field for the DL5248B-TP Zener diode is for regulating the input voltage, allowing the downstream circuit to maintain good performance even with varying experiences in electrical loads. This diode can be used to in the protection of sensitive semiconductor devices, as well as resistive, capacitive and inductive loads. This Zener voltage regulator is also well suited for usage in LMOS logic circuits.

The DL5248B-TP functions by creating an arrangement in which a reverse-biased PN junction is subjected to a voltage potential greater than its breakdown characteristic. This causes a large amount of reverse current to flow. This reverse current moderates the voltage potential appearing across the junction terminals, thus maintaining the junction at a more constant voltage potential. The DL5248B-TP Zener has a Zener voltage range of 4.7 to 5.8V, capable of regulating a range of 21mA which can reach up to 200V.

The wide band gap provides thermal stability, allowing a reliable and constant operation even when exposed to temperatures from -55A°C to150A°C. It features a trimmable zener voltage and also allows a wide temperature coefficient range of 8°C to 12°C. It has very low power consumption with a maximum reverse current of 15.5 uA at 5.8V and a maximum power dissipation of 100mW at 25A°C. Additionally, its junction capacitance decreases with increasing frequency and allows very quick response time.

Usability of the DL5248B-TP

The DL5248B-TP Zener is perfect for applications where a wide temperature range, low power consumption and fast response times are required. As its Zener voltage is adjustable and its temperature coefficient is wide, it can be used in regulated power supplies, automatic equipment, and also in logic circuits, such as microprocessors and computers.

Additionally, due to its highly stable regulation characteristic and fast switching operations, it is used in a variety of communications and networking products, such as for modems, routers, switches and other networking equipment where low supply voltage is present.

This Zener is also used in audio/video equipment and systems, as its low internal capacitance and high stability delivers excellent noise and distortion-free performance.

Conclusion

The DL5248B-TP is an ideal Zener diode for voltage regulation applications in a wide variety of products due to its characteristics such as its adjustable Zener voltage, wide temperature coefficient, low power consumption and fast response times. It is ideal for usage in power supplies, logic circuits, communication equipment and audio/video systems.
