Product details
Overview
HS2A M4G from Taiwan Semiconductor is a 2 A, 50 V high-efficiency surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring 1.0 V typical forward voltage at 2 A and 5 µA maximum reverse leakage at 25°C, used in compact AC/DC adapters and low-voltage SMPS secondary-side rectification.
For engineers reviewing the HS2A M4G datasheet, HS2A M4G pinout, HS2A M4G application, or HS2A M4G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), thermal resistance (80 °C/W), junction capacitance (50 pF), fast recovery time (50 ns), and RoHS/halogen-free compliance for consumer-grade power conversion designs.
Technical Context
This device is a single-die, glass-passivated, planar-junction silicon rectifier optimized for high-frequency switching operation. Its 50 V VRRM, 50 ns trr, and 50 pF CJ support efficient energy transfer in 50–100 kHz flyback and forward converters.
The DO-214AA (SMB) package enables automated placement and provides 80 °C/W junction-to-ambient thermal resistance. Cathode band polarity marking and matte tin-plated leads ensure reliable solderability per J-STD-002 and whisker resistance per JESD 201 Class 2.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR220 | 200 V VRRM, 1.15 V VF @ 2 A, 75 ns trr, DO-204AC (DO-15) through-hole package | Higher voltage rating but slower recovery and larger footprint; unsuitable for space-constrained SMB layouts | Select when higher reverse margin is needed and through-hole assembly is acceptable |
| Vishay VS-2EYH05-M3 | 50 V VRRM, 0.92 V VF @ 2 A, 35 ns trr, same DO-214AA (SMB) package | Lower VF and faster trr improve efficiency but require verification of JEDEC-compliant thermal performance at 2 A | Prefer for highest-efficiency 50 V rectification where layout reuse is critical |
Compared with MUR220 and VS-2EYH05-M3, HS2A M4G offers balanced trade-offs: lowest cost among SMB-packaged 50 V rectifiers, verified 80 °C/W thermal performance on standard FR4, and full halogen-free compliance-making it optimal for high-volume consumer adapter production.

FAQ
What is the maximum repetitive peak reverse voltage rating for HS2A M4G?
The HS2A M4G has a maximum repetitive peak reverse voltage (VRRM) of 50 V. This rating defines the highest reverse-biased voltage the device can block continuously without breakdown. It is validated per JEDEC test conditions and applies across the full operating temperature range of –55°C to +150°C. Designers must ensure peak reverse voltage in the application remains below this value with appropriate safety margin.
Does HS2A M4G support automated PCB assembly?
Yes, HS2A M4G supports automated placement using standard pick-and-place equipment. Its DO-214AA (SMB) package features symmetric lead geometry, matte tin-plated terminals compliant with J-STD-002, and meets IPC-7351B footprint standards. The 0.090 g weight and cathode band marking further enhance placement accuracy and optical recognition yield in high-speed SMT lines.
What is the typical forward voltage drop of HS2A M4G at rated current?
The typical forward voltage drop (VF) of HS2A M4G is 1.0 V at 2 A and 25°C junction temperature, measured under pulsed conditions (PW = 0.3 ms). This value reflects low conduction loss essential for maintaining high efficiency in low-voltage output stages. At elevated temperatures (e.g., 100°C), VF decreases slightly due to semiconductor physics, but system-level derating should follow the forward current derating curve in the HS2A M4G datasheet.
Is HS2A M4G compliant with environmental regulations?
Yes, HS2A M4G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants, and all materials meet EU Directive 2011/65/EU requirements. Lead finish is matte tin, and the device passes JESD 201 Class 2 whisker testing. These attributes make HS2A M4G suitable for export to EU, Japan, and other regulated markets.
How does the thermal performance of HS2A M4G affect PCB layout?
HS2A M4G has a junction-to-ambient thermal resistance (RθJA) of 80 °C/W on standard FR4 with minimum recommended pad layout. To sustain 2 A continuous current at 70°C ambient, the PCB must provide ≥1.5 cm² of 2-oz copper connected to both terminals. Reducing RθJA below 80 °C/W requires internal copper planes or thermal vias-designers should reference the DO-214AA suggested pad layout in the HS2A M4G datasheet to avoid thermal runaway.
