Product details
Overview
SBR20A60CTB from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier in TO263 (D2PAK) package, rated for 60V peak reverse voltage and featuring low forward voltage drop (0.56V typ. @ 20A, 25°C), soft fast switching, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency output rectifier in DC-DC converters and AC-DC power supplies.
For engineers reviewing the SBR20A60CTB datasheet, SBR20A60CTB pinout, SBR20A60CTB application, or SBR20A60CTB equivalent, key selection criteria include forward voltage at high current and temperature, thermal resistance (RθJC = 2°C/W), leakage current stability up to +125°C, and TO263 mechanical compatibility with automated PCB assembly.
Technical Context
This dual-diode rectifier integrates two independent SBR® elements sharing a common cathode terminal, enabling synchronous half-wave or center-tapped full-wave configurations. Its patented super barrier structure delivers lower VF than Schottky diodes while maintaining superior high-temperature leakage performance.
Designed for operation up to +150°C junction temperature, it supports repetitive surge currents up to 180A (8.3ms half-sine) and exhibits soft recovery with minimal reverse recovery charge-critical for reducing EMI in high-frequency switch-mode power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage (VRRM) | 60 V - Maximum blocking capability per leg; defines maximum input/output differential in buck or flyback secondary-side rectification. |
| Average Forward Current (IO) | 20 A total (10 A per leg) - Continuous DC current rating per element at TA = 25°C with adequate heatsinking. |
| Forward Voltage (VF) | 0.56 V typ. @ 20A, 25°C - Directly reduces conduction loss and improves system efficiency in high-current power rails. |
| Thermal Resistance (RθJC) | 2 °C/W - Enables predictable junction-to-case temperature rise; supports compact thermal design with standard D2PAK heatsink pads. |
| Leakage Current (IR) | 100 µA max @ 60V, 125°C - Ensures stable blocking behavior under elevated ambient conditions in automotive under-hood applications. |
| Surge Current (IFSM) | 180 A (8.3ms) - Withstands inrush and transient overloads without degradation, critical for hot-plug and startup robustness. |
Pinout & Package
Package: TO263AB (D2PAK), surface-mount, single-row 3-terminal outline with exposed thermal pad. Case material is UL 94V-0 molded plastic; terminals are matte tin over copper leadframe, solderable per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode 1) | Input anode of first diode element | Connects to transformer secondary or switching node; carries full forward current during positive half-cycle. |
| Pin 2 (Cathode) | Common cathode connection for both diodes | Output node shared by both legs; requires low-inductance, high-current trace routing to minimize voltage overshoot. |
| Pin 3 (Anode 2) | Input anode of second diode element | Used in center-tapped topologies or dual-output configurations; electrically isolated from Pin 1 except through shared cathode. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Combines Schottky-like low VF with PN-junction-level thermal stability-enables 0.56V @ 20A/25°C and <100µA leakage @ 125°C. |
| Soft, fast switching | Low Qrr and controlled reverse recovery reduce EMI generation and snubber losses in >100kHz SMPS designs. |
| AEC-Q101 qualified | Validated for automotive under-hood use including temperature cycling, HTRB, and ESD testing-supports PPAP documentation. |
| Green, RoHS-compliant construction | Halogen- and antimony-free molding compound (<900ppm Br/Cl, <1000ppm Sb); lead-free matte tin terminations meet EU directives. |
Applications
| Automotive DC-DC Converters | Industrial AC-DC Power Supplies |
|---|---|
Use Scenario: 12V–48V bidirectional DC-DC conversion in 48V mild-hybrid vehicle architectures. IC Role / Device Role / Timing Role: Output synchronous rectifier replacing MOSFETs in secondary-side regulation, leveraging low VF to minimize conduction loss at 15–20A load. Use Value: Delivers >95% efficiency at full load while eliminating gate-drive complexity and body-diode conduction penalties. |
Use Scenario: Secondary-side rectification in 300W open-frame industrial power supplies with universal AC input. IC Role / Device Role / Timing Role: Dual-anode common-cathode configuration enables center-tapped transformer full-wave rectification without discrete diode pairing. Use Value: Reduces component count and layout area versus discrete dual-Schottky solutions while maintaining thermal margin up to +85°C ambient. |
| Telecom Server PSUs | LED Driver Secondary Rectification |
Use Scenario: High-density 48V input, 12V/54A output VRM in telecom rack-mounted servers. IC Role / Device Role / Timing Role: Primary output rectifier operating at 200–500kHz switching frequency with forced-air cooling. Use Value: Soft recovery minimizes voltage spikes across primary-side MOSFETs, reducing need for oversized RCD snubbers and improving overall power stage reliability. |
Use Scenario: Constant-current LED driver for outdoor signage with 36V output and 10–20A output current. IC Role / Device Role / Timing Role: Low-VF rectifier in flyback secondary path, directly influencing driver efficiency and thermal management requirements. Use Value: 0.56V forward drop at 20A lowers heat dissipation by ~1.2W vs. conventional 0.75V Schottky, extending heatsink life and reducing thermal derating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current, low-VF rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-20CPH06 | 60V, 20A, TO220 package; VF = 0.62V @ 20A, 25°C; RθJC = 2.5°C/W; not AEC-Q101 qualified. | Requires through-hole mounting and larger board area; suitable for non-automotive industrial use only. | Select when cost sensitivity outweighs surface-mount automation benefits and automotive qualification is unnecessary. |
| ON Semiconductor MUR2060CT | 600V, 20A ultrafast recovery rectifier in TO220; VF = 1.7V @ 20A; higher conduction loss but higher voltage rating. | Used where 600V blocking is required (e.g., PFC boost diodes), not direct replacement for 60V SBR applications. | Choose only if system requires >100V reverse voltage margin-otherwise conduction losses degrade efficiency significantly. |
Compared with VS-20CPH06 and MUR2060CT, SBR20A60CTB offers the lowest VF among 60V-rated 20A rectifiers in surface-mount form, combined with automotive qualification and thermal performance optimized for high-power density layouts.

FAQ
What is the maximum junction temperature for continuous operation?
The SBR20A60CTB has an operating junction temperature range of –65°C to +150°C. For continuous operation at rated 20A total current, thermal design must ensure TJ remains ≤150°C, typically requiring a heatsink or PCB copper area that maintains RθJA ≤ 16°C/W under worst-case ambient conditions.
Is SBR20A60CTB pin-compatible with standard TO263 dual-diode rectifiers?
Yes-SBR20A60CTB uses the standard TO263AB (D2PAK) 3-pin outline with Anode1–Cathode–Anode2 pin assignment. Its footprint matches industry-standard dual-diode D2PAK packages, including IPC-7351 compliant land patterns referenced in Diodes' AP02001 layout guide.
Does the "B" suffix indicate automotive qualification?
No-the "B" suffix denotes the TO263 (D2PAK) package variant. Automotive qualification (AEC-Q101) applies only to part numbers ending in "Q", such as SBR20A60CTBQ-13. The standard SBR20A60CTB is commercial-grade but shares identical electrical and thermal characteristics with its automotive counterpart.
How does SBR technology differ from Schottky and standard PN rectifiers?
SBR uses a proprietary barrier structure that achieves Schottky-like forward voltage (0.56V) while retaining PN-junction thermal stability-leakage stays below 100µA at 125°C, unlike Schottkys which exceed 1mA. It also avoids hard reverse recovery, offering softer switching than fast PN rectifiers like MUR series.
