EMH13-TP

Overview

The EMH13-TP is a Transient Voltage Suppression (TVS) diode manufactured by Micro Commercial Components. It belongs to the SMH series, designed for electrostatic discharge (ESD) protection and transient voltage suppression in electronic circuits. The component is housed in an SOD-323 surface-mount package, facilitating automated assembly and compact board layouts. It functions as a bidirectional or unidirectional clamp depending on the specific variant configuration within the series, providing robust protection against high-energy surges while maintaining low leakage current during normal operation.

Feature Summary

• Provides effective clamping of transient voltage spikes to protect sensitive downstream components from damage.
• Features a compact SOD-323 surface-mount package suitable for space-constrained printed circuit board designs.
• Designed for high reliability in harsh electrical environments with fast response times to ESD events.

Applications

• Protection of data lines in portable consumer electronics such as smartphones and tablets.
• Surge suppression in automotive infotainment and control module interfaces.
• Electrostatic discharge protection for universal serial bus (USB) and high-speed communication ports.

Procurement Notes

Verify the exact part number suffix and manufacturer documentation before procurement, as availability may vary by region. Confirm that the component meets required environmental standards and RoHS compliance for your specific manufacturing process. Check for any distribution restrictions or lead time variations directly with authorized suppliers to ensure supply chain continuity.

Selection Notes

Select this component based on its peak pulse power dissipation rating and breakdown voltage characteristics relative to the protected circuit's operating voltage. Ensure the package type matches the PCB footprint requirements and that the thermal performance aligns with the expected surge energy levels in the target application environment.

Part Context

This device is part of the broader SMH TVS diode family from Micro Commercial Components, which offers various voltage ratings and package options. The SMH series is engineered to meet stringent industry standards for ESD immunity, making it a common choice for protecting I/O ports and signal lines in modern digital systems requiring reliable transient protection.

Replacement Considerations

When evaluating substitutes, prioritize devices with identical package dimensions, similar clamping voltages, and comparable peak pulse power ratings. Verify that alternative components maintain the same response time and leakage current specifications to ensure circuit compatibility without redesigning the surrounding passive components.
