2M15Z

Single Zener Diodes Overview

The 2M15ZHA0 is a glass passivated junction silicon Zener diode manufactured by Taiwan Semiconductor. It utilizes the DO-204AC (DO-15) axial leaded package with matte tin plated leads. The device provides a steady-state power dissipation of 2.0W at a lead temperature of 75°C and supports a peak forward surge current of 15A for an 8.3ms single half sine-wave pulse. It operates within a junction temperature range of -55°C to +175°C and features typical leakage currents less than 1μA.

Single Zener Diodes Procurement Notes

Verify the specific suffix on the component marking, as prefixes or suffixes such as 'H' or 'G' indicate distinct packaging codes, halogen-free status, or AEC-Q101 automotive qualification levels. Confirm compliance with RoHS Directive 2011/65/EU and WEEE 2002/96/EC requirements during sourcing. Ensure the procurement documentation matches the exact manufacturer part number to avoid discrepancies in whisker test compliance or material composition.

Single Zener Diodes Selection Notes

Select this component when a robust through-hole Zener diode with high thermal stability is required. The DO-15 package offers superior power handling compared to smaller surface-mount alternatives. Verify that the circuit environment does not exceed the maximum operating junction temperature of 175°C. Consider the matte tin finish for solderability compatibility with standard assembly processes.

Single Zener Diodes Part Context

This component belongs to the Glass Passivated Junction Silicon Zener Diodes series from Taiwan Semiconductor. It is designed for general-purpose discrete semiconductor applications requiring reliable voltage clamping. The product line emphasizes environmental compliance and mechanical durability through its hermetically sealed glass construction.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the DO-204AC package, 2.0W power rating, and similar Zener voltage characteristics. Verify that any replacement maintains equivalent leakage current specifications and thermal resistance values to ensure circuit performance consistency.
