HS1AL M2G Equivalent & Substitute Parts

Part Overview

The HS1AL M2G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, classified as a fast recovery diode in the DO-219AB (Sub SMA) surface mount package. This component operates at 50 V DC reverse voltage with 1 A average rectified current capacity and features a 50 ns reverse recovery time, making it suitable for standard rectification applications requiring fast switching characteristics.

The HS1AL M2G maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the same package classification.

Substitute Part Grouping Explanation

Substitute parts for the HS1AL M2G are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain constant across all equivalent devices:

Voltage Rating: 50 V DC reverse voltage (Vr) maximum
Current Rating: 1 A average rectified current (Io)
Forward Voltage Drop: 950 mV maximum at 1 A forward current
Reverse Recovery Time: 50 ns (fast recovery classification)
Reverse Leakage Current: 5 µA at 50 V
Junction Capacitance: 20 pF at 4 V, 1 MHz
Package Classification: DO-219AB Sub SMA surface mount
Operating Temperature Range: -55°C to 150°C junction temperature

Parts meeting all these electrical and mechanical specifications are classified as parametric equivalents and direct substitutes. Packaging format variations (such as Cut Tape versus other supply formats) do not affect electrical compatibility.
