1SMA5950HR3G

Single Zener Diodes Overview

The 1SMA5950HR3G is a surface mount Zener diode from the 1SMA5926–1SMA5956 series by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 110 V with a ±5% tolerance, operating within a range of 104.5 V to 115.5 V. The device has a maximum power dissipation of 1.5 W and utilizes a DO-214AC (SMA) package. Electrical characteristics include a test current of 3.4 mA, a maximum dynamic impedance of 300 Ω at the test current, and a leakage current not exceeding 0.5 µA at a reverse voltage of 83.6 V. The junction temperature range spans from -55 °C to +150 °C.

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the specific voltage designation within the 1SMA5926–1SMA5956 series. Confirm the suffix indicates compliance with RoHS directives and halogen-free requirements according to IEC 61249-2-21. Ensure the packaging format aligns with automated placement needs, typically supplied in tape and reel configurations.

Single Zener Diodes Selection Notes

Select this component based on the required 110 V regulation point and 1.5 W power handling capability. Consider the DO-214AC footprint constraints and the low leakage current specifications for sensitive circuits. Evaluate thermal derating requirements if operation exceeds standard ambient temperatures.

Single Zener Diodes Part Context

This part belongs to the 1SMA5926–1SMA5956 series of 1.5 W surface mount Zener diodes. The series covers a wide voltage range from 11 V to 200 V, offering standardized mechanical dimensions and electrical testing parameters across multiple voltage options within the SMA package family.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include parts with identical voltage ratings and package types. Cross-manufacturer replacements must match the 110 V nominal voltage, 1.5 W power dissipation, and DO-214AC physical dimensions.
