BAS16LPQ-7B Equivalent & Substitute Parts

Part Overview

The BAS16LPQ-7B is a general-purpose fast recovery diode manufactured by Diodes Incorporated, designed for surface mount applications in automotive-grade circuits. This component operates at 75 V DC reverse voltage with a 300 mA average rectified current rating and features a 4 ns reverse recovery time, making it suitable for high-speed switching applications. The device is packaged in a 0402 (1006 Metric) form factor and carries AEC-Q101 automotive qualification. The part is currently in active production status with ROHS3 compliance and REACH unaffected classification. Identifying equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and maintain performance specifications across manufacturing batches and procurement cycles.

Substitute Part Grouping Explanation

Substitution of the BAS16LPQ-7B is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for voltage rating, current capacity, switching speed characteristics, thermal performance, and package geometry. The substitution logic is based on the following key parameters:

Voltage - DC Reverse (Vr) (Max): 75 V Current - Average Rectified (Io): 300 mA Reverse Recovery Time (trr): 4 ns Package / Case: 0402 (1006 Metric) Mounting Type: Surface Mount Grade: Automotive Qualification: AEC-Q101

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No derating, performance trade-offs, or application re-qualification is required when substituting between equivalent parts within this grouping.
