DZ23C47-G3-18

Overview

The Vishay DZ23C47-G3-18 is a silicon planar Zener diode from the DZ23-G series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 47 V with a standard tolerance of ±5 %. The device operates at a test current of 2 mA and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 50 nA at 38 V, a dynamic resistance of 97 Ω at 2 mA, and a temperature coefficient ranging from 10 to 12 x 10⁻⁴/°C.

Feature Summary

• Silicon planar construction for reliable voltage regulation
• ESD protection exceeding 8 kV (HBM) and 800 V (MM)
• Green commercial grade material compliance

Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Procurement Notes

Verify the specific ordering code suffix against project requirements. Confirm that the -18 suffix corresponds to the 10,000-unit reel format. Ensure compatibility with RoHS directives and material categorization standards before finalizing procurement orders.

Selection Notes

Select this component when a 47 V Zener voltage is required in a compact SOT-23 footprint. Evaluate thermal management needs as power dissipation drops significantly above ambient temperatures. Verify that the ±5 % tolerance meets circuit precision requirements.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, offering standardized E24 grading. The DZ23C47 variant specifically targets mid-range voltage regulation tasks within consumer and industrial electronics.

Replacement Considerations

Cross-reference with other manufacturers' SOT-23 packaged Zener diodes rated at 47 V. Ensure equivalent dynamic resistance and leakage current specifications are met for direct substitution.
