BZV55-B20,135

Single Zener Diodes Overview

The Nexperia BZV55-B20,135 is a low-power voltage regulator diode housed in a small hermetically sealed glass SOD80C surface-mounted device package. It belongs to the normalized E24 ±2% tolerance series, offering a nominal working voltage of 20 V with a range of 19.6 V to 20.4 V. The component features a total power dissipation capability of up to 500 mW and a non-repetitive peak reverse power dissipation of 40 W. Key electrical characteristics include a maximum differential resistance of 225 Ω at IZ=5 mA, a temperature coefficient ranging from 12.3 to 18.0 mV/K, and a diode capacitance of 60 pF.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental protection
• High precision ±2% voltage tolerance within the E24 series
• Low differential resistance for stable regulation performance

Single Zener Diodes Applications

• General voltage regulation functions
• Voltage reference circuits

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required packing quantity, as the -135 designation indicates tape and reel packaging. Confirm that the ±2% tolerance (B-series) aligns with design requirements rather than the standard ±5% variant. Ensure compatibility with SOD80C footprint dimensions during PCB layout verification.

Single Zener Diodes Selection Notes

Select this component when precise voltage stability is required due to its tight ±2% manufacturing tolerance. The SOD80C package offers a compact solution for high-density circuit designs where space is limited. Consider the thermal resistance characteristics if operating near the maximum power dissipation limits in free air conditions.

Single Zener Diodes Part Context

This part is a member of the Nexperia BZV55 series, which comprises 74 types covering nominal voltages from 2.4 V to 75 V. The series provides both ±2% (B-series) and ±5% (C-series) tolerance options in identical physical packages. The BZV55-B20 represents the specific 20 V variant within the high-precision subset of this widely used low-power zener diode family.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' SOD-80C packaged zener diodes rated for 20 V with ±2% tolerance. Verify that alternative components meet the same hermetic sealing standards and thermal resistance specifications to ensure equivalent performance in existing designs.
