BAV170/ZLVL

Overview

The BAV170/ZLVL is a dual common cathode low-leakage switching diode manufactured by Nexperia, distributed under the NXP USA Inc. brand. It features an SOT-23 (SOT883) surface-mount package with three pins. Key electrical parameters include a peak repetitive reverse voltage of 85 V and a maximum forward current of 320 mA. The device exhibits a low reverse current of 3 pA and a forward voltage drop of 1.25 V at rated current. Operating temperatures range from -55 °C to +150 °C, with a typical recovery time of 3 µs.

Feature Summary

• Dual common cathode configuration for efficient circuit design
• Low leakage current characteristics suitable for precision applications
• High thermal stability with extended operating temperature range

Applications

• Signal switching in consumer electronics
• Protection circuits in automotive systems
• General purpose rectification in industrial equipment

Procurement Notes

Verify the manufacturer designation on official documentation, as Nexperia products are often distributed by NXP entities. Confirm the specific suffix ZLVL corresponds to the required tape and reel packaging format for automated assembly. Ensure compliance with RoHS directives and check for any regional supply restrictions before finalizing procurement orders.

Selection Notes

Select this component when low leakage current and fast switching speeds are critical. The SOT-23 package offers space efficiency for compact designs. Compare the 85 V reverse voltage rating against system peak voltages to ensure adequate margin. Consider the 320 mA forward current limit for load requirements.

Part Context

This component belongs to the BAV series of small-signal switching diodes. It serves as a standard solution for general-purpose switching tasks where low capacitance and high speed are not the primary constraints, but rather low leakage and robustness are needed. It complements other Nexperia diode families like BAS and BAT series.

Replacement Considerations

Direct substitutes include BAV170M or BAV170W from Nexperia, provided pinout and electrical ratings match. Verify package compatibility between SOT-23 variants. Cross-reference with other manufacturers' dual common cathode diodes only if specifications align precisely.
