The MASMLG85CA is a Transient Voltage Suppression (TVS) Diode designed to protect sensitive electronic components from damaging voltage spikes induced by outside sources or static electricity. This miniature device can be used in both military and commercial environments and excels in reliability and electro-static discharge (ESD) protection. It is configured for surface mount technology, making it ideal for compact units, and it features a low voltage clamping capability.

The MASMLG85CA is a unidirectional diode available in the SOD-123 package with a lead spacing of 0.98mm. It provides robust protection against transients and exhibits a low on-state resistance. The device provides a maximum reverse leakage current at stand-off voltage of 1µA and a surge capability of 23A (8/20µs) at 25°C. The device is ESD-protection capable with a rating of 8kV (HBM) at 25°C and 6.5kV (CDM). The glass passivated junction provides highly reliable protection from damaging voltage spikes.

The MASMLG85CA features a low clamping voltage of 11.2V, which helps to protect vulnerable circuits from variations in supply voltage. It also has an operating temperature range between -55°C and 125°C. When powered by a 5V source, the MASMLG85CA exhibits excellent tripping performance and reliable trigger current characteristic.

The leading edge design of the MASMLG85CA coupled with the SOD-123 package design, allows placement close to electronic components to ensure fast response time for efficient protection. The device also features a surge rating of 23A 8/20µs, which is suitable for protecting against high energy transients. The MASMLG85CA is suitable for use in automotive infotainment, electrical power supplies, and industrial controllers.

The working principle of the MASMLG85CA is based on voltage clamp behavior. Unidirectional Transient Voltage Suppressors (TVSs) are designed to react instantaneously to changes in voltage, reacting in nanoseconds to limit the peak voltage to a safe level. Under normal conditions, the voltage across the TVS is equal to the applied voltage. If the applied voltage exceeds the diode\'s reverse breakdown voltage, the TVS quickly clamps the applied voltage to the diode’s breakdown voltage. This voltage clamping action protects circuits from transients and suppressors ESD.

The MASMLG85CA also has an embedded Zener diode that can absorb electrostatic discharges up to 8kV (HBM). This diode protects components from short-duration voltage transients and other surges. The internal Zener diode is triggered when the voltage peak exceeds the diode\'s rated working voltage and absorbs the surge energy, limiting the voltage across the protected component. This device is designed with an optimized breakdown clamping voltage that provides excellent protection against ESD without sacrificing current carrying capability.

The MASMLG85CA is an ideal solution for protecting against high energy transients in both military and commercial applications. It features a very low voltage clamping capability, low on-state resistance, and a robust ESD protection capability. Its small size makes it ideal for use in space-constrained applications, and it is suitable for use in automotive, industrial, and electrical power supply applications. With its robust protection capabilities, the MASMLG85CA is an excellent choice for protecting vulnerable circuits from damaging voltage transients.
