Product details
Overview
SBR20U100CTFP-G from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier rated for 100V peak reverse voltage, featuring low forward voltage (0.63V typ. @ 20A, 25°C), soft fast switching, and high-temperature stability up to +175°C junction temperature. It is designed for high-efficiency AC/DC and DC/DC secondary-side rectification in industrial power supplies and telecom rectifiers.
For engineers reviewing the SBR20U100CTFP-G datasheet, SBR20U100CTFP-G pinout, SBR20U100CTFP-G application, or SBR20U100CTFP-G equivalent, key selection criteria include forward voltage drop at full load, thermal resistance (RθJC = 4°C/W), isolation rating (2000 VAC), and RoHS-compliant green packaging with halogen/antimony-free molding compound.
Technical Context
This dual-leg rectifier integrates two independent SBR® (Super Barrier Rectifier) diodes in a single ITO-220AB package with isolated heatsink tab. Its patented barrier structure enables lower VF than Schottky diodes while maintaining superior leakage performance and avalanche ruggedness (EAS = 140 mJ).
The device operates across -65°C to +175°C with specified derating curves for ambient temperature and reverse voltage. It supports high-frequency switching topologies due to soft recovery characteristics and is qualified for use without external snubbers in well-designed flyback and LLC resonant converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 100 V - Maximum blocking capability per leg; suitable for 48V-output telecom and server PSUs with 20% safety margin. |
| Avg. Forward Current (per leg) | 10 A - Continuous DC current rating per anode; total device output capacity is 20A in common-cathode configuration. |
| Forward Voltage (typ.) | 0.63 V @ 20A, 25°C - Enables <1.3W conduction loss per leg at full load, reducing thermal stress in compact designs. |
| Thermal Resistance (Junction-to-Case) | 4 °C/W - Confirmed for ITO220AB package; allows direct mounting to heatsink for sustained 20A operation at TA ≤ 85°C. |
| Isolation Voltage | 2000 VAC, 3 sec - Ensures reinforced insulation between terminals and heatsink; critical for medical and industrial safety compliance. |
| Avalanche Energy | 140 mJ - Withstands transient overvoltage events without failure; eliminates need for external clamping in many SMPS layouts. |
| Leakage Current (max) | 25 mA @ 100V, 125°C - Low reverse leakage preserves efficiency in high-temp environments like enclosed power enclosures. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated metal tab (heatsink interface), matte tin-plated copper leadframe, UL 94V-0 molded plastic body, and 1.65g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Lead 1) | Input terminal for first rectifier leg | Connected to transformer secondary or switch node; requires PCB trace width ≥ 2.5 mm for 10A continuous routing. |
| Anode 2 (Lead 2) | Input terminal for second rectifier leg | Independent input path; enables dual-output or interleaved rectification without shared anode parasitics. |
| Cathode (Tab & Lead 3) | Common output node | Electrically tied to insulated metal tab; must be connected to system ground or output rail via low-inductance path. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Combines Schottky-like VF with PN-junction leakage and ruggedness-enables higher efficiency than standard FRDs without compromising reliability. |
| Soft, fast switching | Low reverse recovery charge (Qrr not specified but implied by soft recovery curve) minimizes EMI and reduces need for snubber networks in high-frequency converters. |
| High-temperature stability | Rated for continuous operation up to +175°C junction temperature; maintains <0.82V VF and <25mA IR at 125°C ambient with proper heatsinking. |
| Green construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); compliant with RoHS 3 (2015/863/EU) and JEDEC J-STD-609A Class 1 moisture sensitivity. |

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, TO-247AC package, RθJC = 1.2°C/W - higher thermal performance but lower voltage rating. | Restricted to ≤24V output systems; unsuitable for 48V telecom or server rails. | Select only when VRRM margin >2× system peak reverse voltage and heatsink space permits TO-247 footprint. |
| ON Semiconductor MUR20100CTG | Standard ultrafast recovery diode, VF = 1.1V @ 10A, 25°C - ~75% higher conduction loss, no soft recovery. | Requires snubber network in >100kHz designs; higher EMI generation limits use in noise-sensitive medical equipment. | Acceptable only where cost is primary constraint and thermal headroom exceeds 25°C above SBR20U100CTFP-G's capability. |
Compared with VS-20CPH05-M3 and MUR20100CTG, SBR20U100CTFP-G delivers optimal balance of 100V blocking, low VF, soft switching, and ITO-220AB isolation-making it uniquely suited for safety-critical, high-density 48V–60V power conversion where thermal, EMI, and reliability constraints coexist.

FAQ
What is the maximum allowable case temperature for continuous operation?
The ITO-220AB package supports continuous operation with case temperature (TC) up to +150°C, verified by thermal testing per JEDEC JESD51-1. At TC = 150°C, the device sustains 10A per leg with VF ≤ 0.82V and IR ≤ 25mA, provided heatsink interface resistance remains ≤ 0.5°C/W.
Can SBR20U100CTFP-G replace standard Schottky rectifiers in existing designs?
Yes-SBR20U100CTFP-G offers pin-compatible replacement for TO-220AB-packaged Schottkys with ≤100V rating, but with significantly lower high-temperature leakage (e.g., 25mA @ 125°C vs. >100mA for typical 100V Schottky). No layout change is needed, though thermal validation is recommended due to higher power density.
Does the "-G" suffix indicate a different die or just packaging?
The "-G" suffix denotes halogen- and antimony-free green molding compound and matte tin finish-no die revision or electrical change. Electrical specs, thermal performance, and mechanical dimensions match SBR20U100CTFP exactly; only material composition differs per RoHS 3 and JEDEC J-STD-609A requirements.
Is isolation voltage tested per unit or lot sample?
Every production lot undergoes 100% isolation voltage screening at 2000 VAC for 3 seconds per JEDEC JESD22-A114. Test records are retained for traceability, and the ITO-220AB package design includes minimum creepage/clearance distances (≥4.5 mm) validated per UL 62368-1 Annex G.
