Product details

Overview

SBR20150CT from Diodes Incorporated is a 20A dual common-cathode super barrier rectifier rated for 150V peak reverse voltage, featuring low forward voltage (0.79V @ 10A, 125°C), soft fast switching, and TO-220AB packaging. It serves as a high-efficiency output rectifier in AC/DC and DC/DC power supplies for industrial and telecom systems requiring reduced conduction loss and thermal stability up to +175°C.

For engineers reviewing the SBR20150CT datasheet, SBR20150CT pinout, SBR20150CT application, or SBR20150CT equivalent, key selection criteria include forward voltage at elevated temperature, surge current rating (150A IFSM), thermal resistance (2°C/W junction-to-case), and RoHS-compliant green packaging options.

Technical Context

The SBR20150CT integrates two independent 150V/10A rectifying elements in a single TO-220AB package with common cathode configuration, enabling synchronous or interleaved output stage designs. Its patented Super Barrier Rectifier (SBR®) structure replaces conventional PN junctions with a low-barrier Schottky-like metal-semiconductor interface combined with epitaxial doping control.

This architecture delivers lower VF than standard Schottkys while maintaining superior high-temperature leakage performance (≤10mA IR at 150V, 125°C) and soft reverse recovery-critical for reducing EMI in high-frequency switch-mode power supplies operating above 100kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
VRRM	150 V - Maximum non-repetitive reverse voltage per leg; defines safe blocking capability in flyback or boost topologies.
IO (per leg)	10 A - Continuous average forward current per anode; supports 20A total dual-leg output in parallel-configured supplies.
VF @ 10A, 125°C	0.79 V - Confirmed forward drop at full load and high ambient; enables <1.6W conduction loss per leg at 10A.
IFSM (8.3ms)	150 A - Non-repetitive surge rating; withstands inrush and short-circuit transients without bond-wire failure.
RθJC	2 °C/W - Junction-to-case thermal resistance (TO-220AB); allows direct heatsink mounting for >15W dissipation at ΔT = 30°C.
IR @ 150V, 125°C	10 mA - Max reverse leakage per leg; ensures minimal standby loss in offline adapters with high-voltage bias rails.

Applications

Server Power Supply

Industrial Motor Drive

Use Scenario: Secondary-side synchronous rectification in 80 PLUS Titanium-certified 1kW server PSUs.

IC Role / Device Role / Timing Role: Dual-leg output rectifier replacing two discrete Schottkys to reduce component count and layout area.

Use Value: 0.79V VF at 125°C cuts conduction loss by ~18% vs. standard 150V Schottky, improving full-load efficiency by 0.4–0.6%.

Use Scenario: DC bus freewheeling path in 3-phase IGBT inverter stages for HVAC compressors.

IC Role / Device Role / Timing Role: Common-cathode clamp diode handling regenerative energy during PWM dead-time intervals.

Use Value: 150A IFSM rating absorbs motor back-EMF spikes without derating; soft recovery prevents gate driver coupling noise.

Telecom Rectifier Module

LED Streetlight Driver

Use Scenario: Output rectification in -48V telecom rectifier modules operating in hot outdoor cabinets (TA up to 70°C).

IC Role / Device Role / Timing Role: High-current, high-reliability rectifier with proven 175°C junction rating for extended field life.

Use Value: 10mA max IR at 125°C ensures <50mW standby loss per leg-critical for meeting ETSI EN 300 132-2 standby power limits.

Use Scenario: Constant-current output stage in outdoor LED drivers exposed to wide ambient swings (-40°C to +85°C).

IC Role / Device Role / Timing Role: Dual-anode rectifier feeding buck converter input with inherent current sharing between legs.

Use Value: TO-220AB package enables direct bolt-on heatsinking; 2°C/W RθJC supports 20A continuous operation without forced air.

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-20CPH07	Same 150V VRRM, but higher VF (0.85V @ 10A, 125°C); TO-247AC package with higher RθJC (1.5°C/W).	Requires larger heatsink footprint due to TO-247 mechanical envelope; better suited for ultra-low-noise audio PSUs.	Select when lower EMI is prioritized over thermal density; verify PCB cutout compatibility.
ON Semiconductor MUR2015CT	Ultrafast recovery rectifier (trr ≈ 35ns), not SBR; higher VF (1.15V @ 10A, 25°C) and worse high-temp leakage (50mA @ 150V, 125°C).	Higher conduction loss and thermal stress in high-ambient environments; used where cost is primary constraint.	Choose only for legacy designs where SBR qualification is not required; expect ~1.2W extra loss per leg at 10A.

Compared with VS-20CPH07 and MUR2015CT, the SBR20150CT uniquely balances low VF, soft switching, and high-temperature reliability in a compact TO-220AB package-making it optimal for space-constrained, thermally aggressive power supplies where efficiency and EMI co-design are critical.

FAQ

What is the maximum junction temperature rating for SBR20150CT?

The SBR20150CT is rated for continuous operation up to TJ = +175°C, verified per JEDEC JESD22-A108. This rating is supported by its thermal resistance (RθJC = 2°C/W) and stable electrical parameters-including VF and IR-across the full temperature range, making it suitable for sealed or high-ambient environments.

Is SBR20150CT pin-compatible with standard TO-220AB dual-diode rectifiers?

Yes-SBR20150CT uses the industry-standard TO-220AB outline with Anode1–Cathode–Anode2 pin assignment (viewed from bottom). It replaces legacy parts like BYV26E or STTH1602CG without PCB modification, though layout review is recommended to confirm thermal pad clearance and heatsink isolation requirements.

Does SBR20150CT require a heatsink in 10A continuous operation?

Yes-a heatsink is required. At 10A per leg and 0.79V VF, power dissipation exceeds 7.9W per leg. With RθJC = 2°C/W and typical RθCA ≈ 10–20°C/W, junction temperature would exceed 125°C without heatsinking. A minimum 5°C/W heatsink is recommended for reliable 10A operation at TA = 50°C.

How does SBR20150CT differ from standard Schottky rectifiers in high-temperature operation?

Unlike conventional Schottkys, which exhibit exponential IR increase above 125°C, the SBR20150CT's patented barrier structure limits IR to ≤10mA at 150V/125°C-less than half that of comparable Schottkys. This preserves efficiency and prevents thermal runaway in high-ambient applications such as outdoor telecom or industrial enclosures.
