• Features a full metallic bottom to eliminate solder flux entrapment during assembly.
• Includes integral locking tabs that act as efficient heat sinks for external thermal management.
• Designed for compatibility with automatic insertion equipment.
• Provides high ESD protection rated above 16kV per human body model.

Single Zener Diodes Applications

• Voltage regulation in low-profile circuit designs
• High-density surface mount mounting applications
• Automatic insertion equipment manufacturing

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm tolerance levels and compliance status. Confirm the manufacturer's current production status and availability through authorized channels. Ensure the procurement source provides valid traceability data. Check for any recent Product Change Notifications (PCN) or End-of-Life (EOL) announcements from Microsemi regarding this component series.

Single Zener Diodes Selection Notes

Select this component when a precise 3.6 V reference is required with tight tolerance specifications. The Powermite package is suitable for applications needing higher power handling than standard small-signal packages while maintaining a compact footprint. Consider the thermal resistance of 30°C/W junction-to-TAB1 for proper heat sinking requirements in the final design.

Single Zener Diodes Part Context

This part belongs to the 1PMT5913B through 1PMT5956B series of 3.0 Watt Zener diodes. These devices are designed as surface-mount equivalents to the JEDEC registered 1N5913B through 1N5956B axial-leaded series. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options available.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1PMT5914 variants with different tolerances such as 1PMT5914AE3 (±10%) or 1PMT5914DE3 (±1%). Equivalent axial-leaded parts include the 1N5914 series. Verify pinout compatibility and thermal performance when substituting with components from other manufacturers.
