Taiwan Semiconductor Corporation S2MHR5G

Overview

S2MHR5G from Taiwan Semiconductor is a 2 A, 1000 V repetitive peak reverse voltage (V_RRM) standard surface-mount silicon rectifier diode in DO-214AA (SMB) package, featuring glass-passivated junction, low forward voltage drop (1.15 V at 2 A), and 50 A surge capability - used in AC/DC front-end rectification for industrial SMPS and LED drivers.

For engineers reviewing the S2MHR5G datasheet, S2MHR5G pinout, S2MHR5G application, or S2MHR5G equivalent, key selection criteria include verified V_RRM = 1000 V, I_F = 2 A continuous rating, trr = 1500 ns recovery time, R_θJA = 53 °C/W thermal resistance, and DO-214AA mechanical compatibility with automated SMT placement.

Technical Context

This standard recovery rectifier employs a single-die silicon PN junction with glass passivation for enhanced reliability under thermal cycling and humidity exposure. Its 150 °C maximum junction temperature and J-STD-020 Level 1 moisture sensitivity support reflow-compatible manufacturing without baking.

The device exhibits 30 pF junction capacitance at 4 V reverse bias and 125 µA reverse leakage at 125 °C - parameters critical for EMI filtering stability and high-temperature converter hold-up performance. Reverse recovery time of 1500 ns reflects standard (non-fast or ultrafast) switching behavior suitable for ≤100 kHz operation.

Key Specifications

Pinout & Package

DO-214AA (SMB) surface-mount package with cathode band marking; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance; UL 94V-0 molding compound; weight ≈ 0.090 g.

Equivalent & Alternatives

The following parts are listed as comparable options for similar standard recovery rectifier applications.

Compared with STTH2R06 and MUR220, the S2MHR5G delivers higher voltage blocking (1000 V) and standard recovery timing optimized for cost-sensitive, thermally robust industrial rectification - making it unsuitable as a direct replacement where fast recovery or lower V_RRM is required.

Availability

S2MHR5G is available at Aetrix Electronics and suitable for industrial SMPS, LED driver secondary stages, and AC/DC adapter input bridges requiring stable component supply with consistent DO-214AA packaging and 1000 V rating.

Supply support for S2MHR5G includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for S2MHR5G?

The S2MHR5G has a V_RRM of 1000 V, confirmed in the Absolute Maximum Ratings table of Taiwan Semiconductor's S2A–S2V datasheet (Version N2102). This rating applies across the full operating temperature range and defines the highest reverse voltage the S2MHR5G can block repeatedly without breakdown. It is critical for selecting appropriate safety margins in offline rectifier designs.

Does S2MHR5G have a fast or standard reverse recovery time?

The S2MHR5G has a standard reverse recovery time (trr) of 1500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is specified in the Electrical Specifications section and confirms the S2MHR5G is not a fast- or ultrafast-recovery diode. Its recovery behavior suits 50–100 kHz converter topologies where EMI constraints favor moderate switching speed.

Is S2MHR5G RoHS and halogen-free compliant?

Yes, the S2MHR5G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the official datasheet. The device uses matte tin-plated leads and UL 94V-0 molding compound, meeting environmental compliance requirements for commercial and industrial end equipment without exemptions.

What is the thermal resistance from junction to ambient (R_θJA) for S2MHR5G?

The S2MHR5G has a typical R_θJA of 53 °C/W when mounted on a standard FR-4 PCB with no added copper area, per the Thermal Performance table. This value assumes natural convection and defines the temperature rise above ambient per watt of power dissipated. For reliable operation at 2 A, thermal design must ensure junction temperature stays ≤150 °C using adequate copper pour or airflow.

What package type does S2MHR5G use, and what are its key mechanical properties?

The S2MHR5G uses the DO-214AA (SMB) surface-mount package, with polarity indicated by a cathode band. Key mechanical properties include UL 94V-0 flammability rating, J-STD-002 solderable matte tin leads, JESD 201 Class 2 whisker resistance, and approximate weight of 0.090 g. These attributes ensure compatibility with automated assembly and long-term reliability in industrial environments.
