1PMT5934CE3/TR13

Single Zener Diodes Overview

The Microchip Technology 1PMT5934CE3/TR13 is a surface-mount Zener diode rated at 24 V nominal voltage with ±5% tolerance. It operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 3.0 W when mounted to TAB 1 at 60 °C. The device features a maximum reverse current of 1 µA at 18.2 V, dynamic impedance of 19 Ω at 15.6 mA test current, and knee impedance of 500 Ω at 0.25 mA. Forward voltage is 1.2 V at 200 mA. Packaged in the Powermite DO-216 format on tape and reel.

Single Zener Diodes Feature Summary

• Surface mount packaging with full metallic bottom to eliminate solder flux entrapment
• Integral locking tab acts as heat sink for thermal management
• Compatible with automatic insertion equipment
• ESD rating exceeding 16 kV per human body model

Single Zener Diodes Applications

• Voltage regulation in surface mount circuits
• Clamping applications requiring high power handling
• Protection circuits utilizing integral heat dissipation

Single Zener Diodes Procurement Notes

Verify the specific suffix 'e3' indicates RoHS compliance and matte tin plating rather than standard leaded finish. Confirm the 'TR13' designation corresponds to the 13-inch tape and reel configuration containing 12,000 pieces. Ensure the component matches the DO-216 Powermite package dimensions and verify the manufacturer source against Microchip or authorized distributors.

Single Zener Diodes Selection Notes

Select this component when a 24 V reference requires 3 W power handling in a compact surface mount footprint. The design supports high-density mounting due to the low-profile package. Consider the thermal resistance of 30 °C/W from junction to TAB 1 for heat sinking requirements. Verify that the required tolerance aligns with the standard ±5% specification unless a tighter variant is needed.

Single Zener Diodes Part Context

This part belongs to the 1PMT5913B through 1PMT5956B series of 3.0 Watt Zener diodes. The series utilizes the Powermite surface mount package to provide higher power ratings compared to traditional axial equivalents. The numbering system correlates directly to the nominal Zener voltage value.

Single Zener Diodes Replacement Considerations

Check for direct equivalents within the 1PMT59xx series offering identical 24 V characteristics. Verify package compatibility with DO-216 footprints. Confirm thermal performance matches the 30 °C/W junction-to-tab resistance.
