Product details
Overview
SBG3050CT-T-F from Diodes Incorporated is a 30A, 50V surface-mount Schottky barrier rectifier in D2PAK package, featuring low 0.70V forward voltage at 15A/25°C, 250A non-repetitive surge capability, and 1.5K/W junction-to-case thermal resistance-designed for high-efficiency free-wheeling and polarity protection in DC-DC converters.
For engineers reviewing the SBG3050CT-T-F datasheet, SBG3050CT-T-F pinout, SBG3050CT-T-F application, or SBG3050CT-T-F equivalent, key selection criteria include its 50V blocking rating, 30A average output current at TC=100°C, low thermal resistance for heatsink-mounted operation, and RoHS-compliant tin finish compatible with standard reflow profiles.
Technical Context
This dual-diode Schottky rectifier uses guard-ringed die construction to enhance transient robustness and reduce leakage under reverse bias. Its low forward voltage drop and fast switching (no minority-carrier storage) enable high-frequency operation in synchronous rectification and low-voltage inverters.
The device operates across –65°C to +150°C junction temperature range and exhibits 420pF typical junction capacitance at 4V reverse bias and 1MHz-critical for minimizing switching losses in high-speed power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for DC bus or flyback clamp voltage |
| IO @ TC=100°C | 30 A - Continuous average forward current when case temperature is held at 100°C using heatsink |
| VFM @ IF=15A, TC=25°C | 0.70 V - Forward voltage drop per diode; directly determines conduction loss (10.5W at 15A) |
| IFSM (8.3ms) | 250 A - Peak surge current handling; supports motor startup or capacitor charging transients |
| RJC | 1.5 K/W - Thermal resistance from junction to case; enables ~20W power dissipation with 30K ΔT to heatsink |
| Cj @ VR=4V, f=1MHz | 420 pF - Junction capacitance; impacts turn-off speed and EMI in hard-switched topologies |

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 VRRM, but TO-247 package; higher RJC (2.0K/W); 0.68V VF @ 15A | Requires larger PCB area and bolt-down heatsink; better for discrete heatsink mounting | Select when mechanical mounting constraints favor through-hole or higher surge margin is needed |
| ON Semiconductor MBR3050CT | Identical D2PAK package and pinout; 0.72V VF @ 15A; 200A IFSM (vs. 250A) | Lower surge rating may require derating in motor-start applications | Choose for legacy design continuity where 50A surge margin suffices |
Compared with VS-30CPH05-M3 and MBR3050CT, SBG3050CT-T-F delivers superior thermal performance (1.5K/W vs. 2.0K/W) and highest surge tolerance (250A), making it optimal for compact, high-transient industrial and automotive power stages where heatsink real estate is constrained.

FAQ
What is the maximum junction temperature for SBG3050CT-T-F?
The absolute maximum junction temperature is +150°C, with minimum operating temperature of –65°C. Derating begins above TC = 100°C per Figure 1 in the datasheet; sustained operation beyond 150°C risks irreversible parametric shift and bond-wire failure.
Is SBG3050CT-T-F suitable for use without a heatsink?
No-its 30A IO rating is specified only at TC = 100°C with effective heatsinking. Without thermal management, power dissipation exceeds safe limits even at 5A due to 1.5K/W RJC and 0.70V VF; board-level copper pours alone are insufficient for rated current.
Does SBG3050CT-T-F have a built-in thermal shutdown feature?
No-it is a passive rectifier with no integrated thermal protection circuitry. System-level thermal monitoring must be implemented externally via thermistors or controller-based temperature sensing on the heatsink or PCB near the D2PAK tab.
Can SBG3050CT-T-F be used in parallel configurations?
Yes, but requires matched forward voltage characteristics and symmetrical PCB layout. The dual-anode structure allows independent anode routing, and thermal coupling via shared cathode improves current sharing; however, individual current-sense resistors are recommended for precision balancing above 40A total.
