Product details
Overview
SSL33 M6G from Taiwan Semiconductor is a 3A, 30V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, designed for high-efficiency DC/DC conversion with low forward voltage (0.41 V at 3 A), high surge capability (100 A), and junction temperature up to 125°C. It serves as the primary output rectifier in compact AC/DC adapters and LED lighting power supplies.
For engineers reviewing the SSL33 M6G datasheet, SSL33 M6G pinout, SSL33 M6G application, or SSL33 M6G equivalent, key selection factors include its 30 V repetitive peak reverse voltage, 13°C/W junction-to-lead thermal resistance, moisture sensitivity level 1 compliance, and RoHS/halogen-free qualification for industrial and consumer power designs.
Technical Context
This Schottky rectifier uses a single-die construction optimized for low conduction loss in medium-voltage switching applications. Its 0.41 V forward voltage at 3 A and 25°C enables high efficiency in 12–24 V output SMPS stages, while the guard ring structure provides overvoltage robustness without sacrificing speed.
The device operates across –55°C to +125°C junction temperature range and delivers 100 A non-repetitive surge current under 8.3 ms half-sine conditions. Thermal performance is characterized on a 16 mm × 16 mm Cu pad PCB, with RθJA = 53°C/W and RθJC = 15°C/W.

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-3EY30-M3/57T | Same DO-214AB package, 3 A / 30 V, VF = 0.49 V @ 3 A - 0.08 V higher forward drop | Slightly lower efficiency in thermally constrained adapters; identical surge rating (100 A) | Prefer SSL33 M6G where <0.42 V VF is required for thermal margin or efficiency certification |
| ON Semiconductor SB330 | DO-214AA (SMB) package, 3 A / 30 V, VF = 0.52 V @ 3 A - larger VF, smaller footprint, RθJA = 65°C/W | Higher thermal resistance limits power density; suitable only for lower ambient or forced-air environments | Choose SSL33 M6G when board space allows DO-214AB and thermal performance is critical |
Compared with VS-3EY30-M3/57T and SB330, the SSL33 M6G offers the lowest forward voltage and best junction-to-lead thermal resistance in its voltage class, making it optimal for space-constrained, passively cooled 30 W+ adapters and LED drivers where efficiency and reliability are prioritized over minimal footprint.

FAQ
What is the maximum repetitive peak reverse voltage of the SSL33 M6G?
The SSL33 M6G has a maximum repetitive peak reverse voltage (VRRM) of 30 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2310). This rating defines the highest reverse voltage the device can block continuously without breakdown and applies directly to the SSL33 M6G variant within the SSL32–SSL34 family.
Does the SSL33 M6G meet RoHS and halogen-free requirements?
Yes, the SSL33 M6G is RoHS compliant and halogen-free, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet (Version K2310). These qualifications are verified per applicable JEDEC and IPC standards and apply to the full production lot of SSL33 M6G devices supplied by TSC.
What is the forward voltage specification for the SSL33 M6G at rated current?
The SSL33 M6G has a maximum forward voltage (VF) of 0.41 V at 3 A and 25°C, per the Electrical Specifications table in the official datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the upper limit for conduction loss in typical power supply designs using the SSL33 M6G.
Is the SSL33 M6G suitable for use in high-surge environments like motor drives?
The SSL33 M6G supports a peak forward surge current (IFSM) of 100 A for an 8.3 ms half-sine wave, making it suitable for moderate surge conditions such as capacitor-input filter charging in SMPS. However, it is not rated for repetitive motor-commutation surges or unclamped inductive kickback; dedicated TVS or snubber protection is recommended if used near motor control circuits with the SSL33 M6G.
What is the moisture sensitivity level (MSL) of the SSL33 M6G?
The SSL33 M6G has a moisture sensitivity level of MSL 1, per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and requires no baking prior to reflow soldering. This MSL rating is documented in the FEATURES section of the Taiwan Semiconductor SSL32–SSL34 datasheet (Version K2310) and applies to all units shipped as SSL33 M6G.
