Product details

Overview

SBG3050CT-T from Diodes Incorporated is a 30A, 50V surface-mount Schottky barrier rectifier in D2PAK package, featuring low forward voltage drop (0.55V @ 15A, 25°C), high surge capability (250A peak), and thermal resistance of 1.5 K/W. It serves as a primary output rectifier in low-voltage DC-DC converters and free-wheeling diode in synchronous buck regulators.

For engineers reviewing the SBG3050CT-T datasheet, SBG3050CT-T pinout, SBG3050CT-T application, or SBG3050CT-T equivalent, key selection criteria include forward voltage at rated current, junction-to-case thermal resistance, peak repetitive reverse voltage, and surge current rating under 8.3ms half-sine waveform per JEDEC.

Technical Context

This dual-anode common-cathode Schottky rectifier uses guard-ring die construction for transient protection and operates with zero recovery time. Its low V_F and high I_O support high-efficiency power conversion in 12V–48V input systems.

Rated for continuous average output current of 30A at T_C = 100°C, it requires heatsink mounting to maintain junction temperature ≤150°C. Junction capacitance is 420 pF at 4V reverse bias and 1MHz, limiting use in >10 MHz switching applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - Maximum non-repetitive reverse voltage before breakdown; sets upper limit for DC bus or clamp voltage design
I_O	30 A - Average rectified current at case temperature 100°C; defines minimum heatsink requirement
V_FM	0.55 V @ 15A, 25°C - Forward voltage drop directly impacts conduction loss and thermal load in high-current paths
I_FSM	250 A @ 8.3ms - Peak surge rating determines robustness against inrush or fault currents without failure
R_JC	1.5 K/W - Thermal resistance from junction to case; used with heatsink R_CA to calculate max T_J
C_j	420 pF @ 4V, 1MHz - Junction capacitance affects reverse recovery noise and EMI in high-frequency switching nodes

Pinout & Package

D2PAK (TO-263) thermally enhanced surface-mount package with exposed copper drain pad for direct heatsink attachment. Molded plastic case meets UL 94V-0 flammability rating; terminals have bright tin finish, solderable per MIL-STD-202 Method 208.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Anode 1)	Input anode for first Schottky element	Connects to switching node (e.g., high-side FET drain) in half-bridge or buck converter
Pin 2 & 4 (Cathode)	Common cathode terminal	Shared output node; must be routed with low-inductance path to minimize voltage overshoot during commutation
Pin 3 (Anode 2)	Input anode for second Schottky element	Used in dual-output or interleaved topologies; electrically isolated from Pin 1 except through cathode

Key Features

Feature	Design Value
Guard-ring die construction	Improves transient voltage immunity and prevents edge breakdown during fast dv/dt events
Low forward voltage drop	Reduces conduction loss by ~30% vs. comparable silicon rectifiers at 15A, lowering thermal stress
High surge current rating	Withstands 250A non-repetitive surge, enabling use without additional overcurrent protection in many SMPS designs
Thermally optimized D2PAK	1.5 K/W R_JC allows 30A operation with modest heatsinking-critical for compact 1U server PSUs

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-30CPH05-M3	Same 50V V_RRM, but 0.62V V_F @ 15A and 2.0 K/W R_JC	Higher conduction loss and thermal resistance require larger heatsink area	Select when legacy footprint compatibility with TO-220AC is required over D2PAK thermal performance
ON Semiconductor MBR3050CT	Identical 50V/30A rating, but 0.70V V_F @ 15A and no guard ring; RoHS-compliant but not lead-free finish	Lower surge rating (200A) and higher V_F reduce efficiency margin in high-density designs	Prefer for cost-sensitive industrial applications where 0.15V higher V_F is acceptable

Compared with VS-30CPH05-M3 and MBR3050CT, SBG3050CT-T delivers superior thermal performance (1.5 vs. ≥2.0 K/W) and lower conduction loss (0.55V vs. ≥0.62V), making it optimal for space-constrained, high-efficiency 30A rectification where thermal management is critical.

FAQ

What is the maximum allowable case temperature for continuous 30A operation?

The datasheet specifies 30A average rectified current at T_C = 100°C. Operation above this temperature requires linear derating per Figure 1: at 125°C case temperature, maximum I_O drops to 22A. Exceeding 150°C junction temperature risks permanent degradation.

Can SBG3050CT-T be used in a single-anode configuration?

Yes - Pins 1 and 3 are electrically isolated anodes; either can be used independently with Pin 2 & 4 as common cathode. When using only one anode, the unused anode must be left floating or tied to cathode via external circuit, not shorted internally.

Is the D2PAK package compatible with standard reflow profiles for lead-free assembly?

Yes - the bright tin finish meets J-STD-020C Level 1 moisture sensitivity and is qualified for standard Pb-free reflow profiles (peak 260°C, 20–40 sec). The 1.7g mass and thermal mass of D2PAK require controlled ramp rates to avoid delamination.

Does SBG3050CT-T support bidirectional current flow?

No - it is a unidirectional Schottky rectifier. Current flows only from anode to cathode. Reverse conduction is blocked above 50V, and no reverse recovery charge is present due to majority-carrier operation, but it does not conduct in reverse direction under normal bias.
