Product details
Overview
SBR30A100CTE from Diodes Incorporated is a 30A dual common-cathode super barrier rectifier in TO-262 package, rated for 100V peak reverse voltage and 0.67V typical forward voltage at 15A/125°C, delivering low conduction loss and soft switching in high-efficiency AC/DC front-end and DC/DC secondary-side rectification.
For engineers reviewing the SBR30A100CTE datasheet, SBR30A100CTE pinout, SBR30A100CTE application, or SBR30A100CTE equivalent, key selection criteria include per-leg 15A average current rating, 250A non-repetitive surge capability, thermal resistance of 3°C/W junction-to-case, and RoHS-compliant matte tin terminations on copper leadframe.
Technical Context
This dual-element rectifier integrates two independent 100V/15A SBR die in a single TO-262 thermally optimized package with common cathode configuration, enabling synchronous-like efficiency without gate drive complexity. Its patented super barrier structure replaces traditional PN junctions with metal-semiconductor interfaces to suppress leakage and reduce VF drift over temperature.
Designed for high-frequency switching topologies (e.g., LLC resonant, active clamp forward), it exhibits soft reverse recovery (no hard snap-off) and stable performance up to 175°C junction temperature, with IR ≤ 10mA at 100V/125°C - critical for hold-up time and standby loss optimization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage per leg; defines safe operating limit in bridge or center-tap configurations |
| IO (per leg) | 15 A - Continuous average forward current per anode-cathode path at TC = 100°C; enables compact heatsink design |
| VF @ 15A/125°C | 0.67 V - Confirmed typical forward drop under hot, loaded conditions; reduces conduction loss by ~25% vs. standard Schottky |
| IFSM | 250 A - Non-repetitive 8.3ms half-sine surge rating; supports inrush current handling in offline SMPS |
| RθJC | 3 °C/W - Junction-to-case thermal resistance per leg; allows direct mounting to heatsink for high-power density layouts |
| IR @ 100V/125°C | 10 mA - Max reverse leakage per leg at elevated temperature; ensures minimal standby power dissipation |
Pinout & Package
TO-262 package with 3-pin single-row straight lead configuration: Pin 1 = Anode 1, Pin 2 = Cathode (common), Pin 3 = Anode 2. Molded plastic case meets UL 94V-0 flammability rating; matte tin-plated copper leadframe ensures MIL-STD-202 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first rectifying element; connects to transformer secondary or switching node |
| Pin 2 | Cathode (Common) | Shared output node for both elements; routed to bulk capacitor or output rail with minimal inductance |
| Pin 3 | Anode 2 | Input terminal for second rectifying element; enables dual-output or center-tapped transformer interface |
Key Features
| Feature | Design Value |
|---|---|
| Super Barrier Technology | Replaces PN junction with engineered metal-semiconductor interface to achieve lower VF and higher Tj stability than Schottky |
| Soft Switching | No abrupt reverse recovery edge; eliminates EMI spikes and snubber losses in high-frequency converters |
| High-Temp Leakage Control | IR ≤ 10mA at 100V/125°C - maintains efficiency and reliability in sealed or high-ambient environments |
| RoHS & Green Molding | Lead-free matte tin finish and halogen-free epoxy option (-G suffix) meet industrial and automotive environmental compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-30CPH01-M3 | Same 100V/30A rating but uses trench Schottky architecture; VF = 0.72V @ 15A/125°C; RθJC = 4.5°C/W | Higher conduction loss and thermal resistance; requires larger heatsink area in space-constrained OBC designs | Prefer when legacy layout compatibility with TO-247 footprint is required over thermal performance |
| ON Semiconductor NRVB30100CTT4G | Standard Schottky dual; VF = 0.82V @ 15A/125°C; IR = 50mA @ 100V/125°C; no soft recovery | Higher leakage increases standby loss; hard recovery necessitates snubbers in >200kHz designs | Select only for cost-sensitive, low-frequency (<100kHz) applications where EMI filtering budget permits |
Compared with VS-30CPH01-M3 and NRVB30100CTT4G, SBR30A100CTE delivers 7% lower conduction loss, 33% better thermal resistance, and intrinsic soft switching - making it optimal for high-density, high-frequency, and thermally constrained power systems.

FAQ
What is the maximum junction temperature rating for SBR30A100CTE?
The absolute maximum junction temperature is +175°C, validated per JEDEC JESD22-A108. Operation at this limit requires strict thermal design: RθJA must be ≤ 11°C/W with 100°C ambient, and derating curves in Figure 1 mandate IO ≤ 10A at TC = 125°C.
Can SBR30A100CTE replace a standard Schottky rectifier in an existing design?
Yes, with verification of thermal margin and surge capability. Its common-cathode TO-262 pinout matches industry-standard dual rectifiers, but its lower VF and softer recovery may reduce snubber stress and improve efficiency - re-evaluate heatsink sizing and EMI filtering due to altered switching behavior.
Is the SBR30A100CTE suitable for automotive applications?
It meets AEC-Q101 stress test requirements for discrete diodes and is qualified for under-hood use up to 150°C ambient. However, Diodes Incorporated does not authorize its use in safety-critical automotive subsystems (e.g., ADAS, airbag control) without explicit written approval per their Life Support Policy.
What is the meaning of "SBR" in the part number?
"SBR" stands for Super Barrier Rectifier - Diodes Incorporated's proprietary technology that combines metal-semiconductor barrier engineering with epitaxial processing to achieve lower forward voltage and superior high-temperature leakage performance compared to conventional Schottky or PN rectifiers.
