Single Zener Diodes Procurement Notes

Verify that the suffix HR3G corresponds to the specific tape and reel packaging configuration defined by Taiwan Semiconductor. Confirm RoHS compliance and halogen-free status against IEC 61249-2-21 requirements during procurement. Ensure the ordering code matches the exact voltage designation within the 1SMA59xx series to avoid functional mismatches.

Single Zener Diodes Selection Notes

Select this component when a 30 V regulation point is required in a low-profile SMA package. The 1.5 W power rating supports moderate current handling in compact designs. Verify thermal derating curves for operation above 75°C ambient temperatures. Consider the low leakage current specification for high-impedance circuit applications.

Single Zener Diodes Part Context

This part belongs to the 1SMA5926–1SMA5956 series of 1.5 W surface mount Zener diodes manufactured by Taiwan Semiconductor. The series covers a wide voltage range from 11 V to 200 V. All devices share the same DO-214AC mechanical footprint and standardized marking codes, facilitating automated placement and inventory management across various voltage requirements.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 30 V nominal voltage, ±5% tolerance, and 1.5 W power dissipation in a DO-214AC package. Verify equivalent ESD ratings and leakage current specifications. Cross-reference manufacturer datasheets to ensure pinout compatibility and thermal performance alignment.
