Product details

Overview

SBR20A200CTFP from Diodes Incorporated is a 20A dual common-cathode Super Barrier Rectifier rated for 200V peak reverse voltage, with typical forward voltage of 0.72V at 20A/25°C and 24ns reverse recovery time. It uses patented SBR® technology for soft switching and low conduction loss, and is housed in an ITO-220AB package with isolated heatsink mounting capability (2000V_AC isolation).

For engineers reviewing the SBR20A200CTFP datasheet, SBR20A200CTFP pinout, SBR20A200CTFP application, or SBR20A200CTFP equivalent, key selection criteria include its 20A total average output current, 180A non-repetitive surge rating, thermal resistance of 4°C/W (junction-to-case), RoHS-compliant green molding compound, and suitability for high-efficiency AC/DC front-end and DC/DC secondary-side rectification.

Technical Context

This dual-diode rectifier integrates two independent SBR die in a single ITO-220AB thermally enhanced package with electrically isolated tab. Its patented super barrier structure replaces traditional PN junctions with metal-semiconductor interfaces to reduce forward voltage while maintaining fast, soft recovery behavior-critical for reducing EMI in high-frequency SMPS designs.

The device operates across –65°C to +175°C junction temperature range and supports 10,000 V/μs voltage slew rate. Its 2000V_AC isolation between terminals and heatsink enables direct mounting to grounded chassis without insulating hardware, simplifying thermal management in industrial power supplies and telecom rectifiers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum repetitive reverse blocking voltage per leg; defines usable input voltage range in bridge or center-tap configurations.
I_O (Total)	20 A - Total average rectified output current; enables high-power secondary-side rectification in 300–500W SMPS designs.
V_F @ 20A/25°C	0.72 V - Low conduction loss reduces power dissipation by ~30% vs. standard Schottky diodes at same current.
t_rr	24 ns - Fast, soft reverse recovery minimizes switching losses and EMI generation in >100kHz converters.
R_θJC	4 °C/W - Junction-to-case thermal resistance; allows 10W dissipation at 40°C case rise, supporting compact heatsink integration.
V_AC Isolation	2000 V - Terminal-to-heatsink isolation rating; eliminates need for mica washers or silicone pads in grounded-chassis systems.
I_FSM	180 A - Peak surge current handling; sustains brief line transients or startup inrush without degradation.

Pinout & Package

Package: ITO-220AB - Thermally enhanced variant of TO-220 with electrically isolated metal tab (2000V_AC isolation), matte tin-plated copper leadframe, UL 94V-0 molded plastic body, and 1.65g mass.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Anode A)	Anode of first diode leg	Connects to transformer secondary or switching node; shares cathode with Pin 2 for common-cathode configuration.
Pin 2 (Cathode)	Common cathode node	Output terminal for both diodes; must be routed with low-inductance path to minimize voltage spikes during commutation.
Pin 3 (Anode B)	Anode of second diode leg	Enables dual-leg operation (e.g., full-wave center-tap rectification); electrically independent from Pin 1 except at shared cathode.
Tab (Heatsink)	Electrically isolated thermal interface	Provides mechanical mounting and thermal conduction path; rated for 2000V_AC isolation from all pins-no insulator required.

Key Features

Feature	Design Value
Patented SBR® technology	Combines Schottky-like low V_F with PN-junction-like leakage control-enables 0.1mA IR at 200V/25°C and 10mA at 125°C.
Soft, fast switching	24ns t_rr with controlled di/dt tail-reduces ringing and EMI without snubbers in 300kHz+ flyback or LLC designs.
High-temperature stability	Rated for continuous operation up to +175°C junction temperature-supports under-hood automotive and industrial ambient conditions.
Green molding compound	Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb)-meets IPC-4101D and JEDEC J-STD-609A standards for eco-compliance.
Lead-free & RoHS compliant	Matte tin finish on Cu leadframe-solderable per MIL-STD-202 Method 208; compatible with Pb-free reflow profiles.

Applications

Use Scenario: DC bus freewheeling and regeneration path in 3-phase IGBT inverter stages (e.g., HVAC compressors).

IC Role / Device Role / Timing Role: Clamp diode network providing low-loss return path for inductive kickback during PWM dead-time.

Use Value: 180A I_FSM withstands motor stall currents; 24ns t_rr prevents cross-conduction in 15kHz switching.

Telecom Rectifier

EV Onboard Charger

IC Role / Device Role / Timing Role: High-current bridge leg component in full-wave rectifier module with active PFC front-end.

Use Value: 2000V_AC isolation allows direct heatsink mounting to grounded rack chassis-reducing assembly cost and thermal interface resistance.

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-20CPH02-M3	200V, 20A, TO-247 package; VF = 0.75V @ 20A/25°C; trr = 35ns; no isolation rating.	Lacks 2000V_AC isolation; requires insulating hardware when mounted to grounded heatsinks.	Select when higher surge rating (250A IFSM) is prioritized over isolation and thermal resistance.
ON Semiconductor MUR2020CT	200V, 20A, TO-220AB package; VF = 0.92V @ 20A/25°C; trr = 60ns; standard ultrafast recovery.	Higher V_F increases conduction loss by ~2.5W; slower recovery raises EMI risk above 100kHz.	Select only for cost-sensitive, lower-frequency (<50kHz) applications where soft switching is not required.

Compared with VS-20CPH02-M3 and MUR2020CT, SBR20A200CTFP delivers superior thermal performance (4°C/W vs. 5.5°C/W), lower conduction loss, and integrated isolation-making it optimal for space-constrained, high-efficiency, grounded-chassis power systems operating above 100kHz.

FAQ

What is the maximum junction temperature rating for SBR20A200CTFP?

The absolute maximum junction temperature is +175°C, with continuous operation supported across the full –65°C to +175°C range. Derating begins at +125°C case temperature per Figure 4 in DS30992, where average forward current drops linearly from 20A at 25°C to 10A at 125°C case.

Does SBR20A200CTFP require thermal interface material when mounted to a heatsink?

No thermal interface material is required due to its ITO-220AB package's electrically isolated metal tab rated for 2000V_AC isolation. Direct metal-to-metal contact with the heatsink is sufficient for thermal transfer, eliminating insulating pads or pastes and reducing thermal resistance by up to 1.2°C/W.

How does the SBR® technology differ from standard Schottky rectifiers?

SBR® uses a proprietary metal-semiconductor barrier structure that achieves Schottky-level forward voltage (0.72V) while suppressing reverse leakage (0.1mA at 200V/25°C) and enabling soft, fast recovery (24ns). Standard Schottkys exhibit exponential leakage rise above 125°C and lack controlled recovery, causing EMI and voltage overshoot.

Can SBR20A200CTFP be used in place of TO-220AB-packaged rectifiers like SBR20A200CT?

Yes, but with mechanical and thermal distinctions: ITO-220AB has identical pinout and electrical specs but features an isolated tab and lower R_θJC (4°C/W vs. 2°C/W for TO-220AB). Mounting torque and hole alignment differ-refer to Diodes' ITO-220AB outline drawing (DS30992 page 4) before PCB layout.
