Product details

Overview

S3DHM6G from Taiwan Semiconductor is a 3A, 400V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.15V max forward voltage at 3A/25°C, 100A non-repetitive surge capability, and 150°C max junction temperature - deployed in AC/DC front-end stages of switching mode power supplies.

For engineers reviewing the S3DHM6G datasheet, S3DHM6G pinout, S3DHM6G application, or S3DHM6G equivalent, key selection criteria include repetitive peak reverse voltage (400V), thermal resistance (13°C/W junction-to-lead), reverse recovery time (1500ns), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance for industrial-grade power conversion designs.

Technical Context

This device is a single-die, glass-passivated standard recovery rectifier optimized for high-current, medium-voltage DC output stages. Its 1500ns reverse recovery time and 60pF junction capacitance reflect trade-offs favoring low conduction loss over ultra-fast switching.

Thermal performance is defined by R_θJL = 13°C/W and R_θJA = 47°C/W, supporting continuous 3A operation with appropriate PCB copper area. The DO-214AB (SMC) package enables automated placement and meets UL 94V-0 flammability rating.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L04S	400V V_RRM, 3A I_F, but faster t_rr = 60ns (ultrafast); higher V_F = 1.3V typical	Better suited for high-frequency PFC or resonant topologies where switching loss dominates	Select when EMI reduction or >100kHz operation is required; accept higher conduction loss
MBR340	40V V_RRM, Schottky construction, V_F = 0.55V typical, no reverse recovery	Only suitable for low-voltage DC-DC outputs (<40V), not line-referenced AC rectification	Use only in secondary-side low-V_OUT applications; not a voltage-compatible replacement for S3DHM6G

Compared with STTH3L04S and MBR340, the S3DHM6G delivers optimal balance of voltage rating, surge robustness, and thermal efficiency for 400V-class industrial SMPS front ends - where standard recovery characteristics and cost-effective packaging outweigh ultrafast or Schottky trade-offs.

FAQ

What is the maximum repetitive peak reverse voltage rating for S3DHM6G?

The S3DHM6G has a maximum repetitive peak reverse voltage (V_RRM) of 400 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version O2301). This rating defines the highest reverse voltage the diode can block repeatedly without avalanche breakdown under normal operating conditions, making it suitable for 230VAC input-derived DC bus applications with safety margin.

Does S3DHM6G have a RoHS-compliant and halogen-free construction?

Yes, the S3DHM6G is explicitly stated as RoHS compliant and halogen-free in the FEATURES section of the Taiwan Semiconductor documentation. The molding compound meets UL 94V-0, and terminals are matte tin plated - satisfying both environmental compliance and solderability requirements per J-STD-002 for lead-free assembly processes.

What is the reverse recovery time (t_rr) specification for S3DHM6G?

The S3DHM6G has a reverse recovery time (t_rr) of 1500 ns under the test condition of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, per the Electrical Specifications table. This value reflects its standard recovery behavior, distinguishing it from ultrafast or Schottky alternatives, and informs EMI filter and snubber design in 50–100 kHz SMPS topologies.

What package type does S3DHM6G use, and what are its key mechanical attributes?

The S3DHM6G uses the DO-214AB (SMC) surface-mount package, with dimensions documented in the Package Outline Dimensions drawing (HQ2SD07-DO214SMC-036 REV A). Key attributes include UL 94V-0 flammability rating, J-STD-020 Level 1 moisture sensitivity, JESD201 Class 2 whisker resistance, and cathode polarity indicated by a visible band - all verified in the Mechanical Data section.

Can S3DHM6G replace S3DM6G in an existing design?

Yes - S3DHM6G and S3DM6G are identical in electrical specifications, package, and marking; the "H" in S3DHM6G denotes Taiwan Semiconductor's internal revision or process code, not a functional change. Both share V_RRM = 400 V, I_F = 3 A, and DO-214AB (SMC) packaging, and are listed interchangeably in TSC's ordering matrix as valid codes for the same 400V variant.
