BZX84C30VLYT116

Single Zener Diodes Overview

The BZX84C30VLYT116 is a single-channel Zener diode manufactured by ROHM Semiconductor, designed for constant voltage control applications. It features a nominal Zener voltage of 30 V with a tolerance range of 28 V to 32 V, tested at a current of 2 mA. The device supports a maximum power dissipation of 250 mW and operates within a junction temperature range up to 150 °C. Packaged in the standard SOT-23 (SSD3) surface-mount format, it measures 2.4 x 2.9 mm with a height of 1.15 mm. This component is classified as a standard-grade product and is not recommended for use in automotive equipment.

Single Zener Diodes Feature Summary

• Provides stable constant voltage regulation suitable for general electronic circuit protection and reference applications.
• Utilizes a compact SOT-23 surface-mount package to facilitate automated assembly and space-constrained designs.
• Engineered for high reliability under standard operating conditions without specific automotive qualification requirements.

Single Zener Diodes Applications

• General-purpose voltage regulation in consumer electronics
• Over-voltage protection circuits in industrial equipment
• Reference voltage sources in measurement instruments

Single Zener Diodes Procurement Notes

Verify that the application does not require automotive-grade certification, as this model is explicitly excluded from vehicle use. Confirm the ordering part number matches the required tape-and-reel quantity. Ensure design compatibility with the SOT-23 footprint dimensions and thermal characteristics specified in the official datasheet before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a standard 30 V Zener diode is required for non-automotive environments. It serves as a direct replacement for legacy BZX84C30VLFH variants while offering active supply status. Consider the 250 mW power limit and 2 mA test current when designing biasing networks to ensure accurate voltage clamping performance under expected load conditions.

Single Zener Diodes Part Context

This part belongs to the widely adopted BZX84 series of small-signal Zener diodes. It shares the same physical package and pinout configuration as other members in the family, allowing for flexible design choices across various voltage ratings. The 'LY' suffix indicates the specific voltage binning and packaging variant available through standard distribution channels.

Single Zener Diodes Replacement Considerations

BZX84C30VLFH is listed as Not Recommended for New Designs but remains available for existing customers. BZX84C30VLYFH is an active alternative with identical pinout and package specifications, ensuring seamless integration into current layouts without redesign.
