1PMT5953BE3/TR13

Single Zener Diodes Overview

The Microchip Technology 1PMT5953BE3/TR13 is a surface-mount Zener diode housed in the Powermite DO-216AA package. It provides a nominal Zener voltage of 150 V with a standard tolerance of ±5%. The device supports a maximum DC power dissipation of 3.0 watts when mounted to Tab 1 at 60°C, and operates within a junction temperature range of -55°C to +150°C.

Single Zener Diodes Feature Summary

• Features an integral metallic bottom that eliminates solder flux entrapment during assembly.
• Includes unique locking tabs that act as an integrated heat sink for thermal management.
• Designed for compatibility with automatic insertion equipment.

Single Zener Diodes Applications

• Voltage regulation in high-power surface mount circuits
• Protection against overvoltage transients
• Reference voltage generation in industrial electronics

Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' indicates lead-free compliance and confirm the 'TR13' designation corresponds to the 13-inch tape and reel packaging containing 12,000 pieces per manufacturer specifications. Ensure the procurement documentation matches the exact part number to avoid discrepancies in RoHS status or reel dimensions.

Single Zener Diodes Selection Notes

Select this component when a 150 V regulation point is required in a compact surface-mount footprint. The Powermite package offers superior thermal dissipation compared to standard plastic packages due to its full metallic bottom. Verify that the application environment accommodates the specified operating temperature range and that PCB layout allows for proper connection to the Tab 1 heat sink.

Single Zener Diodes Part Context

This component belongs to the 1PMT59xxB series of 3-watt Zener diodes manufactured by Microchip Technology (formerly Microsemi). The series spans voltages from 3.3 V to 200 V, utilizing the standardized DO-216AA Powermite package. These devices are engineered to bridge the gap between low-power SMD components and larger through-hole regulators.

Single Zener Diodes Replacement Considerations

Direct replacements include the non-E3 variant 1PMT5953A/TR13 or other 1PMT5953B variants. When substituting, verify that the alternative maintains the same DO-216AA footprint and thermal characteristics to ensure reliable mounting and heat dissipation.
