Product details

Overview

SSL32 M6G 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, adapters, and DC-DC converters with low forward voltage drop and high surge current capability.

For engineers reviewing the SSL32 M6G datasheet, SSL32 M6G pinout, SSL32 M6G application, or SSL32 M6G equivalent, key selection criteria include V_RRM = 20 V, I_F = 3 A, V_F ≤ 0.41 V at 3 A/25°C, I_FSM = 100 A, and thermal resistance R_θJA = 53 °C/W on standard PCB mounting.

Technical Context

The SSL32 M6G is a single-die, unidirectional Schottky rectifier designed for low-loss DC output rectification in high-frequency switching topologies. Its 20 V V_RRM, 3 A average forward current rating, and 0.41 V max forward voltage at rated current directly support compact, thermally constrained adapter and lighting power stages.

Thermal performance is defined by R_θJL = 13 °C/W and R_θJC = 15 °C/W under JEDEC-standard test conditions (16 mm × 16 mm Cu pad), enabling reliable operation up to T_J = 125 °C with minimal heatsinking in space-limited designs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	20 V - Maximum non-repetitive reverse voltage the device blocks without breakdown; sets upper limit for input/output voltage differential in buck or flyback secondary-side rectification.
I_F	3 A - Continuous average forward current at T_A = 25°C; defines steady-state power delivery capacity in SMPS output stage.
V_F (max)	0.41 V @ 3 A, 25°C - Low conduction loss enables >92% efficiency in 5–12 V output rails with minimal thermal rise.
I_FSM	100 A - Peak non-repetitive surge current for 8.3 ms half-sine; withstands inrush and transient overloads in AC/DC adapters.
T_J (max)	125 °C - Maximum junction temperature; allows operation in sealed enclosures or high-ambient industrial lighting environments.
R_θJA	53 °C/W - Thermal resistance from junction to ambient on standard PCB; determines required board copper area for thermal management.

Pinout & Package

Package: DO-214AB (SMC) - Surface-mount plastic case with cathode band marking, matte tin-plated leads, UL 94V-0 molding compound, and JESD201 Class 2 whisker resistance.

Pin/Terminal	Circuit Role	Design Meaning

Cathode (lead 2)	Forward current exit / reverse voltage reference	Connected to output capacitor and load; polarity marked by visible band; reverse leakage < 200 µA at 20 V/25°C ensures low standby loss.

Key Features

Feature	Design Value

Guard ring structure	Enhances edge termination robustness, improving reliability under voltage transients and partial discharge in lighting ballasts.
High surge current rating	I_FSM = 100 A supports repeated cold-start surges in universal-input adapters without degradation.
Moisture sensitivity level 1	No floor-life limitation or bake requirement before reflow; simplifies SMT line handling and reduces manufacturing cost.

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-M3/5BT	V_RRM = 20 V, I_F = 3 A, V_F = 0.45 V (max) @ 3 A - slightly higher forward voltage; same DO-214AB package.	Higher V_F increases conduction loss by ~0.12 W at full load; may require additional thermal margin in sealed adapters.	Select when Vishay supply chain alignment or qualification history is required; verify thermal derating at 125°C junction.
ON Semiconductor SB320-E3/57T	V_RRM = 20 V, I_F = 3 A, V_F = 0.52 V (max) @ 3 A - 27% higher V_F; same DO-214AB footprint but higher R_θJA (60 °C/W).	Lower efficiency and higher thermal resistance reduce usable output power in thermally constrained designs.	Acceptable for lower-duty-cycle or lower-ambient applications; not recommended for continuous 3 A at >60°C ambient.

Compared with VS-3EWH02-M3/5BT and SB320-E3/57T, the SSL32 M6G delivers the lowest V_F (0.41 V) and best thermal resistance (R_θJA = 53 °C/W), making it optimal for high-efficiency, high-power-density 20 V rectification where thermal headroom is limited.

FAQ

What is the maximum repetitive peak reverse voltage rating for SSL32 M6G?

The SSL32 M6G has a maximum repetitive peak reverse voltage (V_RRM) of 20 V, verified per Taiwan Semiconductor's K2310 datasheet revision. This rating defines the highest reverse-biased voltage the device can block continuously without avalanche breakdown, making it suitable for 12–20 V output applications such as USB-C PD and LED drivers. Exceeding 20 V risks irreversible junction failure.

Does SSL32 M6G meet RoHS and halogen-free requirements?

Yes, SSL32 M6G is RoHS compliant and halogen-free, as explicitly stated in the "Features" section of the official Taiwan Semiconductor datasheet (Version K2310). The device uses lead-free matte tin plating on leads and halogen-free molding compound, satisfying IPC-4101D and IEC 61249-2-21 standards for environmentally restricted electronics manufacturing.

What is the forward voltage drop of SSL32 M6G at rated current?

The SSL32 M6G exhibits a maximum forward voltage (V_F) of 0.41 V at I_F = 3 A and T_J = 25°C, per the "Electrical Specifications" table in the K2310 datasheet. This low V_F is measured under pulsed conditions (PW = 0.3 ms) and contributes directly to reduced conduction losses-approximately 1.23 W at full load-enabling efficient thermal design in space-constrained adapters.

Is SSL32 M6G suitable for high-surge applications like AC/DC adapter inrush?

Yes, SSL32 M6G supports a peak forward surge current (I_FSM) of 100 A for an 8.3 ms half-sine wave, as specified in the "Absolute Maximum Ratings" table. This rating enables reliable handling of cold-start inrush currents in universal-input AC/DC adapters without parametric shift or bond-wire fusing, provided PCB layout maintains adequate thermal mass and trace width.

What package type and marking code does SSL32 M6G use?

SSL32 M6G uses the DO-214AB (SMC) surface-mount package with cathode polarity indicated by a visible band. Its marking code is "SL32", consistent with Taiwan Semiconductor's ordering convention where "x" in SSL3x denotes voltage grade (20 V for SSL32). The device weighs approximately 0.210 g and features J-STD-002 solderable leads.
