ZGL41-200A-E3/97

Single Zener Diodes Overview

The ZGL41-200A-E3/97 is a surface mount glass passivated power voltage-regulating diode manufactured by Vishay General Semiconductor. It operates within the GL41 (DO-213AB) plastic MELF package and provides a nominal Zener voltage of 200 V with a range of 190 V to 210 V at a test current of 3.7 mA. The device supports a maximum continuous forward voltage of 1.5 V at 0.5 A, a maximum surge current of 8000 mA, and a maximum reverse current of 1.0 μA. It features a low Zener impedance of 1.9 Ω at the test current and maintains an operating junction temperature range from -55 °C to +150 °C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details and base quantity requirements. Ensure compliance with RoHS standards and material categorization definitions provided in the datasheet. Confirm that the component meets the required whisker test standards if applicable to your design specifications.

Single Zener Diodes Selection Notes

Select this component when a high-voltage regulation capability near 200 V is required in a compact surface mount form factor. Consider the thermal derating characteristics for steady-state power dissipation above 75 °C lead temperature. Validate the surge current handling capabilities against potential transient events in the target circuit environment.

Single Zener Diodes Part Context

This part belongs to the ZGL41 series of surface mount glass passivated power voltage-regulating diodes. The series covers a wide range of Zener voltages from 100 V to 200 V, all sharing the same GL41 (DO-213AB) mechanical outline. The E3 designation indicates RoHS compliance, while the /97 suffix specifies the standard reel packaging format.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same family include ZGL41-100A through ZGL41-190A, which share identical mechanical dimensions and electrical characteristics except for the specific Zener voltage rating. Verify that the alternative part number's voltage range aligns with the circuit requirements before substitution.

Single Zener Diodes FAQ

What is the polarity indicator on the ZGL41-200A-E3/97?

A red band denotes the Zener diode and marks the positive end, which corresponds to the cathode.

How does the Zener voltage vary with temperature?

The typical Zener voltage exhibits a positive temperature coefficient, increasing as the junction temperature rises from -55 °C to +150 °C.
