Product details
Overview
SSL32HM6G from Taiwan Semiconductor is a 3A, 20V repetitive peak reverse voltage Schottky barrier rectifier in DO-214AB (SMC) package, optimized for high-efficiency switching mode power supplies and lighting converters with low forward voltage drop (≤0.41 V at 3 A, 25°C) and high surge current capability (100 A, 8.3 ms).
For engineers reviewing the SSL32HM6G datasheet, SSL32HM6G pinout, SSL32HM6G application, or SSL32HM6G equivalent, key selection criteria include its 20 V VRRM, 3 A continuous forward current rating, 13 °C/W junction-to-lead thermal resistance, RoHS/halogen-free compliance, and cathode-band polarity marking on the SMC body.
Technical Context
This discrete Schottky diode operates as a unidirectional power rectifier with single-die construction and guard-ring overvoltage protection. Its low VF enables reduced conduction loss in high-frequency DC/DC converters, while its 100 A IFSM rating supports robust transient handling in adapter and SMPS input stages.
Thermal performance is characterized with RθJL = 13 °C/W and RθJA = 53 °C/W on a 16 mm × 16 mm Cu pad PCB. Reverse leakage remains ≤200 μA at 25°C and ≤50 mA at 100°C under rated 20 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 20 V - Maximum non-repetitive reverse voltage before breakdown; defines safe operating limit in 24 V rail applications |
| IF | 3 A - Continuous average forward current; supports sustained output in compact 30–60 W SMPS designs |
| VF | ≤0.41 V @ 3 A, 25°C - Low conduction loss improves system efficiency and reduces heatsink requirements |
| IFSM | 100 A @ 8.3 ms - Withstands line surges and inrush currents without failure in AC-DC front ends |
| TJ max | 125 °C - Maximum junction temperature; enables operation in enclosed, thermally constrained environments |
| RθJL | 13 °C/W - Efficient heat transfer to PCB copper; allows direct thermal coupling to ground plane for passive cooling |
| Moisture Sensitivity | Level 1 (J-STD-020) - No floor life limitation; suitable for standard SMT reflow without baking |
Pinout & Package
Package: DO-214AB (SMC), surface-mount, molded plastic case with matte tin-plated leads, cathode indicated by band. Weight: ~0.210 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary or switch node); requires adequate copper area for thermal dissipation |
| Cathode | Forward current exit / reverse blocking terminal | Marked by visible band; ties to output rail or filter capacitor positive; determines polarity-sensitive placement in layout |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances ruggedness against transient overvoltage events without derating VRRM |
| Low VF (≤0.41 V) | Reduces power loss by >30% vs. comparable 20 V silicon rectifiers at 3 A, improving thermal margin |
| DO-214AB mechanical outline | Standardized footprint compatible with automated pick-and-place; supports 3,000-unit tape-and-reel packaging |
| RoHS + halogen-free | Meets IPC-1752A material declaration requirements for industrial and consumer end equipment |
| J-STD-002 solderability | Ensures reliable reflow joint formation without lead-tin oxidation or dewetting issues |
Applications
| Switching Mode Power Supply (SMPS) | AC-DC Adapters |
|---|---|
Use Scenario: Secondary-side rectification in 24 V output, 40–60 W flyback converters. IC Role / Device Role / Timing Role: Schottky rectifier replacing fast recovery diodes to minimize conduction loss and improve light-load efficiency. Use Value: Enables ≥90% typical efficiency at full load due to 0.41 V VF, reducing thermal stress on PCB and enabling smaller heatsinks. | Use Scenario: Output rectification in universal-input (90–264 VAC) wall adapters for consumer electronics. IC Role / Device Role / Timing Role: Primary output diode in isolated buck-derived topologies with tight space constraints. Use Value: DO-214AB footprint allows high-density layout; 100 A IFSM withstands cold-start surges without derating. |
| LED Lighting Drivers | DC-DC Buck Converters |
Use Scenario: Rectification in constant-current LED drivers for commercial downlights (24–48 V systems). IC Role / Device Role / Timing Role: High-frequency synchronous rectifier alternative where gate drive complexity is avoided. Use Value: Low VF maintains stable current regulation across temperature; halogen-free compound meets IEC 62474 compliance. | Use Scenario: Output stage rectifier in 12 V input, 5 V/3 A step-down converters for embedded control modules. IC Role / Device Role / Timing Role: Unidirectional power path device converting switched inductor current into regulated DC output. Use Value: RθJL = 13 °C/W enables direct thermal coupling to 16 mm × 16 mm Cu pad, limiting ΔT to <40°C at full load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EWH02-M3/54 | Same 20 V VRRM, 3 A IF, but TO-277 package (smaller footprint, higher RθJA = 70 °C/W) | Better suited for ultra-thin profiles; less effective PCB heat spreading than DO-214AB | Select when board thickness <1.2 mm constrains height, accepting higher thermal resistance |
| ON Semiconductor SB320-E3/54 | 20 V VRRM, 3 A IF, DO-214AA (SMB) package; VF = 0.52 V (max) - 27% higher conduction loss | Lower cost SMB variant; requires larger voltage derating margin due to higher IR at 100°C | Select for cost-sensitive, non-thermally constrained applications where 0.11 V higher VF is acceptable |
Compared with VS-3EWH02-M3/54 and SB320-E3/54, SSL32HM6G delivers superior thermal performance via DO-214AB's lower RθJL and better PCB copper coupling, making it preferred for sustained 3 A operation in ambient temperatures up to 70°C.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of SSL32HM6G?
The SSL32HM6G has a VRRM of 20 V, verified per Taiwan Semiconductor's K2310 datasheet. This rating defines the highest reverse voltage the diode can block repeatedly without breakdown. It is specifically assigned to the SSL32 variant, distinguishing it from SSL33 (30 V) and SSL34 (40 V). Engineers must ensure system reverse transients remain below this value in all operating conditions.
Does SSL32HM6G have a specified forward voltage (VF) at 3 A and 100°C?
No - the SSL32HM6G datasheet specifies VF only at 25°C (≤0.41 V, max, at IF = 3 A). At elevated temperatures, VF decreases slightly, but no typ/max value is published for 100°C. Designers should use the 25°C value with appropriate thermal derating or consult TSC's Fig.4 (Typical Forward Characteristics) curve for interpolation.
Is SSL32HM6G suitable for reflow soldering without pre-baking?
Yes - SSL32HM6G is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no baking prior to standard Pb-free reflow. Its matte tin-plated leads also comply with J-STD-002 for reliable solder wetting, supporting high-yield SMT assembly without process modification.
What does the "HM6G" suffix indicate in SSL32HM6G?
The "HM6G" suffix denotes Taiwan Semiconductor's internal packaging and environmental code: "H" = halogen-free compound, "M6" = DO-214AB (SMC) package with tape-and-reel packing (3,000 units), and "G" = green (RoHS-compliant) material grade. This matches the ordering information on page 3 of the K2310 datasheet and confirms full regulatory compliance.
How is polarity marked on SSL32HM6G?
SSL32HM6G uses a cathode band - a distinct, opaque black or dark gray stripe near one end of the DO-214AB body - to identify the cathode terminal. This marking aligns with JEDEC DO-214 standards and is visible under standard AOI inspection. The anode is the unmarked end; correct orientation is critical to prevent reverse conduction in circuit operation.
