1PMT4113/TR7

Single Zener Diodes Overview

The Microchip Technology 1PMT4113/TR7 is a surface mount low noise 1 watt Zener diode in the Powermite series. It features a nominal Zener voltage of 19V at a test current (IZT) of 250µA, with a maximum Zener impedance (ZZT) of 150 Ohms and a maximum reverse leakage current (IR) of 0.05µA. The device operates within a junction temperature range of -55°C to +150°C, dissipating up to 1.0W of steady-state power. It utilizes a DO-216 package with a full-metallic bottom for heat dissipation.

Single Zener Diodes Feature Summary

• Features a unique locking tab design that serves as an integral heat sink with very low thermal resistance junction-to-case.
• Includes a full-metallic bottom construction that eliminates the possibility of solder flux entrapment during assembly.
• Provides low noise density performance measured within a 1–3 kHz frequency bandpass filter at the specified test current.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-density and low-profile mounting on printed circuit boards
• Automatic insertion equipment integration

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging format and compliance status. Confirm RoHS compliance requirements match the intended application environment. Ensure procurement channels provide valid traceability for the component lot. Check for any product change notifications or lifecycle updates prior to finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a 19V reference is required in a surface mount configuration. Consider the 1W power handling capability and low thermal resistance for applications requiring efficient heat dissipation. Evaluate the low noise characteristics if signal integrity is critical in the regulated circuit. Verify that the DO-216 footprint matches the PCB layout constraints.

Single Zener Diodes Part Context

This part belongs to the Powermite surface mount low noise 1 watt Zener package series. It serves as a surface mount equivalent to JEDEC registered axial-leaded series such as 1N4099 through 1N4135, offering additional power handling capabilities within a compact form factor designed for modern automated manufacturing processes.

Single Zener Diodes Replacement Considerations

Surface mount equivalents include the 1N4113UR series in the DO-213AA package. Axial-leaded replacements are available in the 1N4099 through 1N4135 series. Verify pinout compatibility and thermal management requirements when substituting with these alternative packages.
