MINISMDE190-2

Overview

The Littelfuse MINISMDE190-2 is a surface-mount transient voltage suppression (TVS) diode designed for circuit protection. It features a standoff voltage of 19V and a breakdown voltage range of 21.1V to 23.4V. The device handles a peak pulse power of 1500W at the 10x1000µs waveform. It operates within a temperature range of -55°C to +150°C and utilizes a DO-214AC (SMC) package.

Feature Summary

• Provides robust clamping capabilities against high-energy transients
• Features glass passivated chip junction construction
• Includes built-in strain relief for mechanical stability

Applications

• ESD protection for data lines per IEC 61000-4-2 standards
• EFT protection for data lines per IEC 61000-4-4 standards
• Protection of sensitive electronic equipment from lightning-induced transients

Procurement Notes

Verify the specific part number suffix to confirm polarity and exact electrical characteristics, as Littelfuse TVS series often utilize suffixes to denote variations in breakdown voltage or configuration. Ensure the component meets RoHS compliance requirements if specified for your project. Cross-reference the datasheet for the specific variant to confirm the presence of built-in strain relief and correct package dimensions before finalizing procurement.

Selection Notes

Select this component when protecting circuits requiring 1500W surge capability in an SMC package. It is suitable for applications demanding fast response times and low leakage current. Consider the operating temperature range and the specific standoff voltage requirements of the protected line to ensure adequate margin against normal operating voltages while providing effective transient suppression.

Part Context

This component belongs to the LCE Series of low capacitance transient voltage suppression diodes. The series is engineered specifically to shield sensitive electronics from voltage spikes caused by lightning and other transient events. These devices are characterized by their high peak pulse power handling and fast response times, making them reliable choices for industrial and automotive circuit protection.

Replacement Considerations

Direct replacements must match the 1500W peak pulse power rating, SMC package footprint, and similar breakdown voltage ranges. Verify that substitute components also offer glass passivation and built-in strain relief to maintain equivalent reliability and mechanical performance in the target application.
