Overview
The Good-Ark Semiconductor 1.5SMA5934A is a surface mount Zener diode housed in the DO-214AC (SMA) package. It provides a nominal Zener voltage of 24V with a tolerance range of 22.8V to 25.2V. The device supports a DC power dissipation of 1.5W and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum Zener impedance of 15.6Ω at an test current of 18.2mA, a reverse leakage current of 0.5µA at 5V, and a maximum forward voltage of 1.2V at 200mA.
Feature Summary
- Glass passivated chip construction for enhanced durability
- Built-in strain relief mechanism integrated into the molded plastic case
- Low inductance design suitable for high-frequency applications
- High peak reverse power dissipation capability
Applications
- Voltage stabilization circuits
- Signal clipping applications
- Protection against transient overvoltages
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number and date codes against official Good-Ark Semiconductor documentation. Ensure the receiving inspection confirms compliance with RoHS3 standards and validates that the physical markings match the specified device marking code. Confirm packaging integrity prior to soldering processes.
Selection Notes
Select this component when a precise 24V reference is required in a compact surface mount footprint. The 1.5W power rating allows for higher energy handling compared to standard small-signal diodes. Evaluate thermal management requirements based on the derating curve to ensure reliable operation under continuous load conditions within the specified temperature limits.
Part Context
This component belongs to the 1.5SMA59xxA series of surface mount Zener diodes manufactured by Good-Ark Semiconductor. The series covers a wide voltage range from 3.3V to 200V, all utilizing the DO-214AC package. This specific variant targets applications requiring stable voltage regulation with moderate power handling capabilities in space-constrained designs.
Replacement Considerations
Substitute parts must match the 24V Zener voltage, 1.5W power dissipation, and DO-214AC package dimensions. Verify that alternative manufacturers offer equivalent impedance and leakage specifications to maintain circuit performance without redesign.
