Product details
Overview
SSL33HM6G from Taiwan Semiconductor is a 3A, 30V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, optimized for high-efficiency switching mode power supplies and DC-DC converters with low forward voltage (VF ≤ 0.41 V at 3 A, 25°C) and high surge capability (IFSM = 100 A). It features guard ring overvoltage protection and RoHS/halogen-free compliance.
For engineers reviewing the SSL33HM6G datasheet, SSL33HM6G pinout, SSL33HM6G application, or SSL33HM6G equivalent, key selection criteria include repetitive peak reverse voltage (VRRM = 30 V), junction temperature range (–55°C to +125°C), thermal resistance (RθJL = 13°C/W), moisture sensitivity level (MSL 1), and cathode-band polarity marking for reliable automated assembly and thermal management in compact power designs.
Technical Context
This Schottky rectifier uses a single-die construction with platinum-silicide or comparable low-barrier metallization to achieve fast recovery (no stored charge) and minimal switching loss. Its 30 V VRRM rating targets mid-voltage DC-DC stages where efficiency and thermal headroom are critical-e.g., 24 V input rails feeding 5 V/3.3 V point-of-load converters.
The device operates across –55°C to +125°C junction temperature, with RθJA = 53°C/W on a 16 mm × 16 mm Cu pad PCB, enabling stable performance in thermally constrained adapters and lighting drivers without forced airflow. Reverse leakage remains ≤200 μA at 25°C and ≤50 mA at 100°C under rated VR.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS33HE3/57T | VRRM = 30 V, IF = 3 A, VF ≈ 0.45 V @ 3 A - slightly higher forward drop; same DO-214AB package | Higher VF increases conduction loss in thermally limited USB-C adapters | Preferred where Vishay supply chain alignment or qualification history is required |
| ON Semiconductor SB330 | VRRM = 30 V, IF = 3 A, VF ≈ 0.49 V @ 3 A; RθJA ≈ 60°C/W - higher thermal resistance | Requires larger copper area or airflow to match SSL33HM6G's thermal performance | Acceptable for cost-sensitive, non-thermally constrained lighting modules |
Compared with SS33HE3/57T and SB330, SSL33HM6G delivers the lowest VF (≤0.41 V) and best thermal resistance (RθJL = 13°C/W), making it optimal for high-density, convection-cooled power stages where efficiency and board area are co-constrained.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of SSL33HM6G?
The SSL33HM6G has a VRRM of 30 V, meaning it reliably blocks up to 30 V of reverse voltage in repetitive operation. This rating is validated per JEDEC test conditions and defines its safe operating range in buck converter outputs or flyback secondary circuits where reverse voltage transients may reach 25–28 V. Exceeding 30 V risks avalanche breakdown and permanent damage to the SSL33HM6G.
Does SSL33HM6G require baking before SMT reflow due to moisture sensitivity?
No, SSL33HM6G does not require baking before reflow. It is rated MSL Level 1 per J-STD-020, indicating unlimited floor life at ≤30°C/60% RH. The device can be placed directly from tape-and-reel into standard lead-free reflow profiles without dry-pack storage or pre-bake cycles-reducing process complexity and cost in high-volume SSL33HM6G assembly lines.
What is the forward voltage (VF) specification for SSL33HM6G at 3 A and 100°C junction temperature?
The SSL33HM6G datasheet specifies VF only at TJ = 25°C (≤0.41 V at IF = 3 A); no typ/max VF value is provided at 100°C. However, typical Schottky VF decreases ~2 mV/°C, so VF at 100°C is estimated ~0.26–0.29 V. For design-critical thermal analysis, engineers should verify actual VF using the SSL33HM6G's Fig.4 (Forward Characteristics) curve at elevated temperature rather than extrapolating.
Is SSL33HM6G pin-compatible with SSL32HM6G or SSL34HM6G?
Yes, SSL33HM6G shares identical DO-214AB (SMC) package dimensions, pinout, and thermal pad layout with SSL32HM6G (20 V) and SSL34HM6G (40 V). All three use the same anode/cathode terminal configuration and marking convention (SL33 cathode band), enabling direct PCB footprint reuse across the SSL32–SSL34 family when adjusting VRRM for different input/output voltage margins.
What is the junction-to-lead thermal resistance (RθJL) of SSL33HM6G, and why does it matter?
The SSL33HM6G has RθJL = 13°C/W, measured from junction to lead under JEDEC-standard test conditions. This low value indicates efficient heat transfer from the silicon die directly into the PCB copper via the leads-enabling passive cooling in adapters and LED drivers without thermal vias or heatsinks. Designers use RθJL to calculate junction temperature rise above PCB temperature, ensuring SSL33HM6G stays within its 125°C TJ max limit.
