1N5936P/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5936P/TR12 is a unidirectional voltage regulator diode with a nominal Zener voltage of 30 V. It operates within a junction and storage temperature range of -65 °C to +175 °C. The device provides a steady-state power dissipation of 1.5 W at a lead temperature of 85 °C, or 1.25 W at an ambient temperature of 25 °C. Electrical characteristics include a maximum dynamic impedance (ZZT) of 28 Ohms at the test current (IZT) of 12.5 mA, and a maximum reverse current (IR) of 750 µA at a reverse voltage (VR) of 22.8 V.

Single Zener Diodes Feature Summary

• Hermetically sealed voidless hard glass casing with tungsten slugs for high reliability
• Metallurgically enhanced internal contact design providing lower thermal resistance
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Inherently radiation hard construction

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High reliability applications requiring hermetic sealing
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify the specific suffix 'P' against official documentation to confirm plastic body construction versus standard glass packaging. Confirm RoHS compliance status as commercial grades may differ from military screening levels. Ensure the TR12 tape and reel configuration matches assembly requirements. Validate that the component meets the required JEDEC type number specifications for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a 30 V regulation point is required in an axial-leaded package. Consider the 1.5 W power rating and the -65 °C to +175 °C operating temperature range for harsh environments. Evaluate the 28 Ohm dynamic impedance for noise sensitivity. Compare against other tolerances if tighter voltage accuracy is needed, noting that different suffixes denote varying tolerance levels.

Single Zener Diodes Part Context

This part belongs to the 1N5913BG through 1N5956BG series of available axial-leaded 1.5 watt glass Zener diodes. The series offers a wide selection of voltages from 3.3 to 200 volts. While the base series utilizes glass encapsulation, the 'P' suffix indicates an optional plastic body variant. The series supports various screening levels, including reference to MIL-PRF-19500 for high-reliability needs.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5936BG for glass hermetic versions and 1N5936BP for plastic axial leads. Surface mount alternatives are available in DO-213AB, SMB, SMAJ, and Powermite packages within the same voltage series.
