Product details
Overview
SBR20U100CTE-G from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier rated for 100V peak reverse voltage, featuring ultra-low forward voltage (0.63V typ. @ 20A, 25°C), soft fast switching, and TO262 package for high-power AC/DC front-end rectification in industrial power supplies.
For engineers reviewing the SBR20U100CTE-G datasheet, SBR20U100CTE-G pinout, SBR20U100CTE-G application, or SBR20U100CTE-G equivalent, key selection criteria include forward voltage at full load, thermal resistance (2°C/W junction-to-case), high-temperature leakage performance (25mA max @ 100V, 125°C), and RoHS-compliant green molding compound construction.
Technical Context
This dual-leg SBR rectifier integrates two independent 10A-rated super barrier diodes sharing a common cathode terminal, enabling center-tapped transformer full-wave rectification or parallel current handling. Its patented super barrier structure replaces traditional PN junctions with low-barrier metal-semiconductor interfaces to reduce VF while maintaining high surge capability (200A IFSM).
Designed for operation up to +175°C junction temperature, it delivers stable forward characteristics across temperature (VF = 0.82V max @ 20A, 125°C) and exhibits low reverse leakage (0.5mA typ. @ 100V, 25°C), making it suitable for high-efficiency, thermally constrained switch-mode power supply outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage (VRRM) | 100 V - Withstands transient surges up to 100V without breakdown in rectifier applications. |
| Avg. Forward Current (IO per leg) | 10 A - Supports continuous 10A DC output per anode leg; total device rating is 20A with shared cathode. |
| Forward Voltage (VF) | 0.63 V typ. @ 20A, 25°C - Reduces conduction losses by ~30% vs. standard Schottky diodes at same current. |
| Junction-to-Case Thermal Resistance | 2 °C/W - Enables direct heatsink mounting for efficient thermal management in high-power designs. |
| Non-Repetitive Surge Current (IFSM) | 200 A - Handles 8.3ms half-sine inrush events common during AC line startup or capacitor charging. |
| Operating Temperature Range | −65°C to +175°C - Rated for under-hood automotive, industrial motor drives, and high-ambient lighting systems. |
Pinout & Package
Package: TO262 - 3-pin single-ended through-hole package with isolated metal tab (cathode-connected), matte tin-plated copper leadframe, UL 94V-0 molded plastic body, 1.355g weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | AC input leg 1 | Accepts alternating input from one side of center-tapped transformer or bridge configuration. |
| Anode 2 (Pin 2) | AC input leg 2 | Accepts alternating input from second side; enables full-wave rectification with shared cathode output. |
| Cathode (Tab/Pin 3) | DC output common node | Electrically connected to metal tab; must be mounted to heatsink and tied to system ground or output rail. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low forward voltage | 0.63V typical at 20A/25°C - directly lowers power loss and improves efficiency in 12–48V output SMPS. |
| Soft fast switching | No reverse recovery tail current - eliminates switching noise and EMI in high-frequency rectifiers. |
| High-temperature stability | Leakage remains ≤25mA at 125°C/100V - ensures reliability in enclosed, fanless power enclosures. |
| Green molding compound | Halogen-free, RoHS-compliant polymer - meets IPC-4101D/21 and JEDEC J-STD-020 reflow requirements. |
Applications
| Server Power Supply | Industrial Motor Drive |

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-20CPH05-M3 | 50V VRRM, 20A IO, TO247 package, higher VF (0.75V typ.) | Limited to ≤50V systems; requires larger heatsink due to higher conduction loss. | Select only if lower voltage rating suffices and TO247 mechanical fit is required. |
| ON Semiconductor MUR2010CTG | Ultrafast recovery rectifier (trr = 60ns), 100V, 20A, higher VF (1.1V min) | Higher switching loss and EMI; suited for snubber-assisted circuits where softness is less critical. | Prefer when cost sensitivity outweighs efficiency goals and thermal margin is ample. |
Compared with VS-20CPH05-M3 and MUR2010CTG, SBR20U100CTE-G delivers superior efficiency at 100V-class operation via lower VF and zero reverse recovery charge-critical for compact, high-density power supplies where thermal headroom is constrained.

FAQ
What does the "-G" suffix indicate in SBR20U100CTE-G?
The "-G" suffix denotes Diodes Incorporated's halogen-free, green molding compound version compliant with IPC-4101D/21 and JEDEC J-STD-020. It is identical in electrical and thermal performance to the non-G variant but uses environmentally optimized encapsulation material.
Can SBR20U100CTE-G replace standard Schottky rectifiers in existing designs?
Yes-its pin-compatible TO262 footprint and common-cathode configuration allow drop-in replacement where 100V rating and 20A total current meet requirements. However, verify thermal interface design due to its 2°C/W RθJC and ensure no voltage overshoot exceeds 100V during transients.
Is the metal tab electrically isolated in SBR20U100CTE-G?
No-the metal tab is internally connected to the cathode terminal (Pin 3). When mounted to a heatsink, the heatsink becomes part of the cathode net and must be electrically isolated from other system potentials unless intentionally grounded to the cathode reference.
What is the maximum recommended case temperature for continuous operation?
The absolute maximum case temperature is 175°C, but the DC forward current derating curve shows usable current drops to 10A at 125°C case temperature. For reliable long-term operation, maintain TC ≤ 110°C with appropriate heatsinking and airflow.
