MTZJ10SA

Single Zener Diodes Overview

The MTZJ10SA is a hermetically sealed glass Zener diode manufactured by Taiwan Semiconductor Corporation. It operates within the DO-34 (JEDEC DO-204) through-hole package and provides a nominal Zener voltage of 9.66 V with a tolerance range of 9.41 V to 9.90 V. The device supports a maximum power dissipation of 500 mW at 25°C ambient temperature, tested at a current of 5 mA. It features pure tin-plated leads for solderability and maintains an operating junction temperature range from -55°C to +175°C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction with compression bonded design
• Corrosion-resistant external surfaces and readily solderable pure tin plated leads
• Polarity indicated by cathode band marking

Single Zener Diodes Applications

• Low voltage stabilizers or voltage references
• Adapters
• Lighting applications
• On-board DC/DC converters

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation before procurement. Suffixes such as A0, R0, G, and RG denote identical physical components but specify distinct packaging formats like Ammo Boxes or Reels. Confirm that the required voltage tolerance code matches the application needs, as these codes define the specific Zener voltage subdivision ranges.

Single Zener Diodes Selection Notes

Select this component based on the required Zener voltage stability and the need for hermetic sealing in harsh environments. Ensure the circuit design accommodates the 500 mW power dissipation limit and the specified test current of 5 mA. Verify that the DO-34 through-hole form factor aligns with the board layout requirements and that the lead spacing matches the target footprint dimensions.

Single Zener Diodes Part Context

This part belongs to the MTZJ series of 500mW Zener diodes produced by Taiwan Semiconductor. The series covers a wide selection of voltages ranging from 2V to 56V. All devices in this family share the same DO-34 glass package and hermetically sealed construction standards, providing consistent mechanical and environmental performance characteristics across different voltage ratings.

Single Zener Diodes Replacement Considerations

Direct substitutes include other MTZJ10 variants with different tolerance codes (e.g., MTZJ10B, MTZJ10C). Cross-manufacturer replacements must match the DO-34 package, 500 mW rating, and 9.66 V nominal voltage specifications.
