BAW156/ZLR

Overview

The BAW156/ZLR is a dual diode array manufactured by NXP USA Inc., housed in a SOT-23 (TO-236AB) surface-mount package. It features a common anode configuration with standard epitaxial technology. Key electrical parameters include a maximum continuous reverse voltage of 75 V and a repetitive peak reverse voltage of 85 V. The device supports a repetitive peak forward current of 500 mA and a DC forward current of 160 mA. It exhibits low leakage current, typically 3 pA, and a typical switching time of 0.8 µs.

Feature Summary

• Low-leakage current performance suitable for sensitive circuits
• Medium-speed switching capability with typical 0.8 µs transition time
• Automotive-grade reliability through AEC-Q101 qualification

Applications

• Low-leakage current applications in surface mounted circuits
• General purpose rectification in compact electronic designs
• Automotive electronics requiring qualified components

Procurement Notes

Verify component status as obsolete on major distributor platforms before procurement planning. Confirm availability through authorized channels or alternative sourcing strategies due to end-of-life designation. Ensure compatibility with existing design specifications if substituting. Check RoHS compliance status for environmental regulations. Validate supply chain stability given the discontinued production status.

Selection Notes

Select this component for applications requiring low leakage and medium-speed switching in a small SOT-23 footprint. Consider the common anode configuration for circuit topology requirements. Evaluate the 75 V reverse voltage rating against system operating conditions. Assess the need for AEC-Q101 qualification if deploying in automotive environments. Note the obsolete status when planning long-term production runs.
