1N4730AW-TP

Overview

The MCC 1N4730AW-TP is a silicon planar power Zener diode with a nominal voltage of 3.9V and a maximum power dissipation of 1.0W at 25°C ambient temperature. It utilizes an SOD-123 surface-mount package, measuring approximately 2.85mm in length and 1.80mm in width. The device features a 5% voltage tolerance, a test current of 64mA, and a maximum reverse leakage current of 150µA at 11V. Thermal resistance from junction to ambient is rated at 100 K/W, supporting operation within a temperature range of -55°C to +150°C.

Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Designed in a low-profile surface-mount package for compact circuit integration
• Provides stable breakdown characteristics across a wide operating temperature range

Applications

• DC power supply voltage regulation
• Voltage reference circuits
• Overvoltage protection stages

Procurement Notes

Verify the specific suffix configuration when ordering, as the standard part includes RoHS compliance while halogen-free variants require an additional suffix. Confirm that the component meets moisture sensitivity level 1 requirements for your assembly process. Ensure sourcing channels are authorized distributors to guarantee genuine parts and full traceability, as unauthorized sources do not receive warranty coverage.

Selection Notes

Select this component for applications requiring a 3.9V reference in a surface-mount footprint. Consider the 100 K/W thermal resistance and derating curve if operating above 100°C ambient. Verify that the 150µA leakage current specification aligns with your circuit's precision requirements. Compare against through-hole alternatives if board space allows for different mounting styles.

Part Context

This component belongs to the 1N4729AW through 1N4761AW series, which covers a voltage range from 3.6V to 75V. All devices in this family share the same SOD-123 package dimensions and 1.0W power rating. The series provides extensive voltage selection options for designers needing standardized Zener voltages in a compact surface-mount form factor.

Replacement Considerations

Cross-reference with other manufacturers' 1N4730 equivalents in the SOD-123 package. Verify that substitute parts match the 3.9V nominal voltage, 1.0W power rating, and 5% tolerance. Check thermal resistance and leakage current specifications to ensure compatibility with existing circuit designs.
