1PMT5920BT3

Single Zener Diodes Overview

The onsemi 1PMT5920BT3 is a single unidirectional Zener diode in the POWERMITE (DO-216AA) surface-mount package. It features a nominal Zener voltage of 6.2 V with a tolerance range of 5.89 V to 6.51 V, tested at a current of 60.5 mA. The device provides a maximum DC power dissipation of 3.2 W when mounted with the cathode tab at 75°C, or 500 mW at 25°C ambient temperature. Key electrical parameters include a maximum dynamic impedance of 2 Ω and a reverse leakage current of 5 μA at 4.0 V. The component operates within a junction temperature range of -55°C to +150°C.

Single Zener Diodes Feature Summary

• Utilizes the POWERMITE package design featuring a full metallic bottom to eliminate solder flux entrapment during assembly.
• Incorporates integral locking tabs that function as an effective heat sink for thermal management.
• Offers a low-profile form factor with a maximum height of 1.1 mm and a compact footprint area of 8.45 mm².
• Provides high electrostatic discharge protection capability rated at 16 kV per the Human Body Model.

Single Zener Diodes Applications

• Protection circuits in cellular phones and portable electronic devices
• Voltage regulation in business machines and industrial equipment
• Consumer electronics requiring space-saving surface mount solutions

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging quantity; T1 indicates 3,000 units per reel while T3 denotes 12,000 units per reel. Confirm if the 'G' suffix is required for lead-free compliance. Ensure the procurement specification matches the exact voltage tolerance and test current requirements defined in the datasheet electrical characteristics table.

Single Zener Diodes Selection Notes

Select this component when a 6.2 V reference is needed in a DO-216AA footprint. Evaluate the thermal resistance from junction-to-tab (23 °C/W) against the application's heat dissipation needs. Consider the 60.5 mA test current requirement for accurate voltage regulation. Verify that the operating environment stays within the specified -55°C to +150°C temperature range.

Single Zener Diodes Part Context

This part belongs to the 1PMT59xxB series of 3.2 Watt Zener diodes manufactured by onsemi. The series covers a wide breakdown voltage range from 6.2 V to 47 V. These devices are designed to replace larger through-hole packages while maintaining similar thermal performance in a significantly smaller surface-mount profile.

Single Zener Diodes Replacement Considerations

Direct replacements within the same series include 1PMT5920BT1 (3,000 units/reel) and 1PMT5920BT3G (lead-free version). Cross-manufacturer equivalents in the DO-216AA package should be verified for matching power dissipation and impedance specifications.
