Engineering Selection Recommendations

The BAT54LSYL is a direct parametric equivalent to the BAT54LS-QYL. Both components are manufactured by Nexperia USA Inc. and share identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts may be based on inventory availability and moisture sensitivity level (MSL) requirements.

The BAT54LS-QYL carries an MSL rating of 3 (168 Hours), while the BAT54LSYL carries an MSL rating of 1 (Unlimited). For applications with extended storage periods or high-humidity environments prior to assembly, the BAT54LSYL offers superior moisture protection. Both parts maintain active product status and full compliance with ROHS3 and REACH regulations, ensuring long-term supply chain viability and regulatory acceptance.

Frequently Asked Questions (FAQ)

Q: Can BAT54LSYL be used as a direct replacement for BAT54LS-QYL?

A: Yes. The BAT54LSYL is a parametric equivalent with identical electrical ratings (30 V reverse voltage, 200 mA average rectified current, 800 mV forward voltage at 100 mA), reverse recovery time (5 ns), and mechanical packaging (SOD-882, DFN1006BD-2). Both parts are manufactured by Nexperia USA Inc. and carry ROHS3 compliance and REACH unaffected status.

Q: What is the difference between BAT54LS-QYL and BAT54LSYL?

A: The primary difference is the Moisture Sensitivity Level (MSL). The BAT54LS-QYL has an MSL rating of 3 (168 Hours), while the BAT54LSYL has an MSL rating of 1 (Unlimited). All other electrical and mechanical parameters are identical. The MSL difference affects storage and handling requirements prior to assembly.

Q: Are these parts suitable for automotive applications?

A: The BAT54LS-QYL carries AEC-Q100 automotive-grade qualification. The BAT54LSYL does not list AEC-Q100 qualification in the provided specifications. For automotive applications requiring AEC-Q100 certification, the BAT54LS-QYL is the specified choice.

Q: What is the SOD-882 package?

A: SOD-882 is a surface mount diode package, also referenced as DFN1006BD-2 in the supplier device package designation. This is a miniature form factor suitable for high-density PCB layouts.

Q: Can these diodes handle reverse voltage spikes above 30 V?

A: No. The maximum DC reverse voltage rating is 30 V. Operation above this rating will result in device failure. Circuit design must ensure reverse voltage stress does not exceed this specification.

Q: What is the typical forward voltage drop at operating current?

A: The maximum forward voltage is specified as 800 mV at 100 mA forward current. Actual forward voltage will be lower under typical operating conditions but must not exceed this maximum rating.
