Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official Panjit documentation to confirm packaging details, as suffixes may indicate variations in reel size or tape specifications. Ensure compliance requirements match project needs, specifically checking for RoHS 2.0 and halogen-free status. Confirm the marking code D1 corresponds to the intended inventory tracking and identification protocols within your supply chain.

Single Zener Diodes Selection Notes

Select this component when a 3.3 V reference is required in a compact SOD-323 footprint. The 200 mW power rating suits low-power signal conditioning tasks. Verify that the 28 Ω impedance meets circuit sensitivity requirements. Consider the -55°C to +150°C operating range for environmental robustness. Compare leakage current limits against strict low-power standby designs.

Single Zener Diodes Part Context

This part belongs to the MMSZ5221BS ~ MMSZ5267BS series of surface mount silicon Zener diodes. The series covers voltages from 2.4 V to 75 V with a consistent 200 mW power dissipation capability. All devices share the SOD-323 plastic molded case and planar die technology. The series is designed for high-volume automated assembly in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers' SOD-323 Zener diodes rated for 3.3 V and 200 mW. Verify pinout compatibility and physical dimensions. Check if alternative parts meet the same 28 Ω impedance and 25 μA leakage specifications. Ensure thermal derating curves align with application constraints.
