Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N4704 designation is utilized by multiple vendors including Motorola/NXP, Central Semiconductor, and Microchip. Ensure the suffix /TR indicates tape and reel packaging if required. Confirm the package type matches the DO-7 specification rather than DO-35 or DO-204AH variants found in other datasheets. Cross-reference electrical parameters such as leakage current and tolerance against the specific supplier's documentation to ensure compliance with design requirements.

Single Zener Diodes Selection Notes

Select this component when a 17 V Zener voltage with 500 mW power rating is required in a through-hole configuration. The DO-7 package offers a smaller footprint compared to conventional DO-204AA packages. Consider the low leakage current of 50 nA for sensitive analog applications. Verify that the ±5% tolerance aligns with the circuit's voltage regulation accuracy needs. Ensure the operating temperature range meets the environmental conditions of the target application.

Single Zener Diodes Part Context

The 1N4704 series comprises low-power Zener diodes ranging from 1.8 V to 200 V. These devices are commonly used in consumer electronics and industrial equipment for basic voltage clamping and reference tasks. The 1N4704 specifically targets the 17 V segment of this range. While originally associated with Motorola, Microchip Technology produces this part under the same JEDEC numbering system, maintaining compatibility with legacy designs.
