Overview
The GSAZ23C22 is a surface mount Zener diode from the GSAZ23Cxxx series manufactured by Good-Ark Semiconductor. It features a nominal Zener voltage of 22 V with a ±5% tolerance, tested at 5 mA. The device operates in an SOT-23 package and dissipates up to 300 mW. Key electrical parameters include a maximum reverse current of 100 nA at 17 V, a maximum Zener impedance (ZZK) of 55 Ω at 1 mA, and a typical temperature coefficient of 0.090 %/°C. The junction-to-ambient thermal resistance is 417 °C/W, supporting operation between -55°C and +150°C.
Feature Summary
- Tight voltage tolerance of ±5% for precise regulation
- MSL Class 1 compatibility for standard assembly processes
- Wide operating junction temperature range
Applications
- General voltage regulation circuits
- Mobile and handheld electronic systems
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and specific lot traceability requirements against project specifications before finalizing orders. Ensure packaging integrity matches storage guidelines.
Selection Notes
Select this component when a 22 V reference is required in compact designs. The SOT-23 footprint suits space-constrained layouts. Verify that the 300 mW power dissipation rating accommodates the expected thermal environment without exceeding the 417 °C/W thermal resistance limit.
Part Context
This part belongs to the GSAZ23Cxxx series, which provides a broad selection of Zener voltages ranging from 2.4 V to 51 V. All variants share identical physical dimensions and electrical testing conditions, differing primarily in breakdown voltage and associated marking codes.
Replacement Considerations
Cross-reference with other manufacturers offering SOT-23 Zener arrays with 22 V nominal voltage and 300 mW ratings. Verify pinout compatibility and ensure equivalent thermal resistance and tolerance specifications match the original design constraints.
