Introduction

The 1N5369BRLG is a Zener diode manufactured by ON Semiconductor. Designed for use in standard EIA and military temperature curves, this diode provides ESD and surge protection for low-voltage circuits. Its low on-state voltage, low thermal resistance and tight tolerances provide effective overvoltage and short circuit protection when used as a Zener diode in a variety of electronic circuits.

Application Field

The 1N5369BRLG is most commonly used as a Zener diode in low-voltage circuit protection, such as in computers, TVs, smartphones and other electronic devices. The diode is commonly used in precision voltage reference circuits, voltage limiters and transient voltage suppression circuits. It is also used as a switch in surge suppression circuits.

Construction

The 1N5369BRLG is constructed from a semiconductor die enclosed in standard plastic or ceramic packaging. It is available in different package types, including glass, epoxy and ceramic. The diode\'s highly conductive, high-purity semiconductor die helps reduce thermal resistance for improved voltage and current handling capabilities.

Working Principle

Zener diodes such as the 1N5369BRLG operate as a diode in the forward direction, but when the reverse applied voltage reaches or exceeds its Zener breakdown voltage, it conducts in reverse. Unlike other components, the Zener current is not limited by an internal resistance, and can be large if the applied voltage continues to increase.When the voltage across the diode is greater than the Zener voltage, a large current can flow and the diode becomes a short circuit, thus providing surge and transient protection. This short circuit current will not increase even if the voltage continues to increase, which prevents the voltage from getting too high and damaging the device.

Conclusion

The 1N5369BRLG is a reliable and cost-effective Zener diode designed for low-voltage circuit protection applications. It can be used as a switch in surge-limiting circuits, and its low thermal resistance ensures efficient and reliable voltage and current handling.
