Product details
Overview
SBR30A100CTB-13 from Diodes Incorporated is a 30A dual common-cathode Super Barrier Rectifier in TO263AB (D2PAK) package, rated for 100V peak repetitive reverse voltage, with typical forward voltage of 0.78V at 15A/25°C and 0.85V at 15A/125°C, designed for high-efficiency DC/DC conversion in automotive power supplies and industrial SMPS.
For engineers reviewing the SBR30A100CTB-13 datasheet, SBR30A100CTB-13 pinout, SBR30A100CTB-13 application, or SBR30A100CTB-13 equivalent, key selection criteria include its ultra-low VF, AEC-Q101 qualification, soft-switching behavior, 180A non-repetitive surge rating, and thermal resistance of 3°C/W per leg - critical for thermally constrained high-current rectification.
Technical Context
This dual-diode rectifier integrates two independent SBR® elements sharing a common cathode terminal, enabling synchronous or interleaved full-wave configurations. Its trench-based Super Barrier structure delivers avalanche ruggedness (480mJ EAS, 8kW PARM) far exceeding standard Schottky diodes while maintaining low conduction loss.
The device operates across –65°C to +150°C junction temperature range, with leakage current limited to 10µA at 100V/125°C - significantly lower than comparable Schottkys - reducing thermal runaway risk in high-temperature environments such as under-hood automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum reverse blocking capability without breakdown; defines usable input voltage headroom in buck or flyback outputs. |
| IO (per leg) | 15 A - Continuous DC current per anode-cathode path at TC = +150°C; enables 30A total dual-leg output in parallel layout. |
| VF @ 15A/25°C | 0.78 V - Low conduction loss reduces I²R heating; improves system efficiency by ~0.5–1.2% vs. standard Schottky alternatives. |
| RθJC (per leg) | 3 °C/W - Enables direct heatsinking via exposed cathode tab; supports >20W dissipation per leg with modest thermal interface. |
| IFSM | 180 A - Withstands 8.3ms half-sine surge; protects against inrush and short-circuit transients in 12V/24V automotive systems. |
| EAS | 480 mJ - Avalanche energy rating confirms robustness during inductive switching events; eliminates need for external snubbers in many topologies. |
Pinout & Package
TO263AB (D2PAK) package with exposed metal cathode pad on underside for thermal and electrical connection. Three terminals: two anodes (A1, A2) and one common cathode (K).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | Anode 1 | First rectifying path input; electrically isolated from A2; connects to primary-side switch node in center-tapped or dual-output converters. |
| A2 | Anode 2 | Second rectifying path input; independent of A1; supports interleaved or redundant output designs. |
| K | Common Cathode | Shared output node; large copper slug provides low-inductance, low-resistance return path and primary thermal conduction path to PCB heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| Trench SBR® technology | Enables avalanche-rated operation (480mJ EAS) without degradation - critical for reliability in unregulated or transient-prone power rails. |
| Ultra-low VF at high temperature | 0.85V max at 15A/125°C - maintains efficiency in hot environments where conventional Schottkys suffer rapid VF rise and leakage escalation. |
| Soft, fast switching | Low reverse recovery charge (Qrr not specified but implied by soft recovery curve) minimizes EMI and voltage overshoot during turn-off in high-frequency SMPS. |
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, temperature cycling, and HAST - suitable for engine control units and ADAS power stages. |
Applications
| Automotive DC/DC Converters | Industrial SMPS Outputs |
|---|---|
Use Scenario: 12V-to-5V/3.3V step-down converter in infotainment head unit with 20A load requirement. IC Role / Device Role / Timing Role: Dual-leg synchronous rectifier replacing MOSFETs in secondary side; common-cathode configuration simplifies layout and reduces component count. Use Value: 0.78V VF at 25°C cuts conduction loss by ~35% vs. 40V Schottky, lowering thermal stress on PCB and enabling smaller heatsinks. | Use Scenario: 48V-to-12V telecom power supply operating continuously at 65°C ambient. IC Role / Device Role / Timing Role: Output rectifier in phase-shifted full-bridge topology; handles 15A per leg with shared cathode return. Use Value: 10µA IR at 100V/125°C prevents thermal runaway under sustained high-temp operation - unlike Schottkys that exceed 100µA at same condition. |
| Server PSU Secondary Side | Renewable Energy Inverter Auxiliary Supply |
Use Scenario: 12V auxiliary rail in 3kW server power supply with strict efficiency and footprint constraints. IC Role / Device Role / Timing Role: Dual-anode rectifier feeding parallel VRMs; leverages low RθJC (3°C/W) for direct board-level thermal management. Use Value: Exposed cathode tab allows direct mounting to internal copper plane, achieving <10°C ΔT at full load - eliminating discrete heatsink. | Use Scenario: Isolated gate driver supply in solar inverter IGBT module with wide ambient swing (–25°C to +85°C). IC Role / Device Role / Timing Role: Input rectifier for flyback-derived auxiliary supply; withstands repeated 180A surges during grid fault events. Use Value: 180A IFSM and 480mJ EAS ensure no failure during line dip recovery or inverter short-circuit shutdown sequences. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, high-reliability rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS30H100CG-TR | 30A dual Schottky in D2PAK; VF = 0.72V @ 15A/25°C but IR = 200µA @ 100V/125°C; no avalanche rating. | Lacks AEC-Q101 qualification and avalanche ruggedness; unsuitable for automotive transients or high-temp sustained loads. | Select only for cost-sensitive, non-automotive, <60°C ambient applications where leakage and surge immunity are non-critical. |
| MBR30H100CTG | 30A dual Schottky in TO220AB; VF = 0.79V @ 15A/25°C; RθJC = 4.5°C/W; no AEC-Q101 or soft-switching claim. | Higher thermal resistance limits power density; through-hole package increases assembly cost and reduces PCB routing flexibility. | Prefer only when legacy TO220 footprint must be retained or when tape-and-reel automation is unavailable for D2PAK. |
Compared with STPS30H100CG-TR and MBR30H100CTG, SBR30A100CTB-13 offers superior thermal performance (3°C/W), guaranteed avalanche survival (480mJ), and automotive qualification - making it the sole choice for thermally dense, mission-critical, or transient-heavy rectification where reliability outweighs marginal VF advantage.

FAQ
What is the maximum continuous current per anode at +150°C case temperature?
The SBR30A100CTB-13 supports 15A average forward current per anode at TC = +150°C, as specified in the Absolute Maximum Ratings table. This is derated linearly from 30A at TC = +25°C using the provided forward current derating curve (Figure 1), confirming 15A per leg at the upper thermal limit.
Does this part have a common-cathode configuration, and how is it implemented physically?
Yes - the SBR30A100CTB-13 integrates two independent anode terminals (A1, A2) bonded to a single, large-area cathode metal slug. The cathode is exposed on the underside of the TO263AB package and serves as both the electrical common node and primary thermal conduction path to the PCB heatsink.
Is the SBR30A100CTB-13 suitable for use in a synchronous rectification topology?
No - it is a passive rectifier, not a synchronous MOSFET controller or driver. However, its low VF and soft switching make it ideal as a high-performance replacement for synchronous FETs in cost- or complexity-constrained designs where gate drive timing and control overhead must be avoided.
How does the "Green" designation affect soldering and compliance?
The "-13-G" suffix denotes halogen- and antimony-free construction (<900ppm Br/Cl, <1000ppm Sb), fully compliant with RoHS 2015/863/EU. It uses matte tin over copper leadframe and is qualified for standard Pb-free reflow (260°C/30s), with no special soldering profile required beyond JEDEC J-STD-020 Level 1 moisture handling.
