Product details
Overview
MBRD660CTTRL from Vishay is a surface-mount, center-tap Schottky rectifier rated for 6 A average forward current per leg and 60 V maximum DC reverse voltage, with low 0.65 V forward voltage drop at 3 A and 125°C junction temperature. It serves as a dual-anode, common-cathode power rectifier in high-frequency switching power supplies, battery charging circuits, and reverse polarity protection.
For engineers reviewing the MBRD660CTTRL datasheet, MBRD660CTTRL pinout, MBRD660CTTRL application, or MBRD660CTTRL equivalent, key selection criteria include its D-PAK (TO-252AA) package thermal resistance (6°C/W junction-to-case), 490 A non-repetitive surge capability, and center-tap configuration enabling compact dual-output or synchronous rectification topologies.
Technical Context
The MBRD660CTTRL integrates two Schottky diodes in a single-center-tap configuration, sharing one cathode terminal and featuring separate anode terminals. Its low VF and fast recovery support high-efficiency operation in DC/DC converters and flyback supplies operating up to several hundred kHz.
Designed for surface-mount assembly on PCBs with limited board space, it uses a D-PAK outline with exposed thermal pad for enhanced heat dissipation. The guard ring structure improves ruggedness against transient overvoltage and ensures long-term reliability under repetitive avalanche conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) per leg | 6.0 A average forward current - supports continuous dual-leg operation at full rating with proper heatsinking |
| VRRM | 60 V maximum DC reverse voltage - suitable for 48 V system inputs and 36 V nominal battery charging rails |
| VF @ 3 A, TJ = 125°C | 0.65 V - enables >92% efficiency in 12 V output buck converters at medium load |
| IFSM @ 5 μs | 490 A peak surge - withstands inrush currents during hot-plug or cold-start events |
| RthJC | 6 °C/W junction-to-case - requires minimal external copper area for thermal management at 6 A DC |
| CT @ 5 V | 145 pF per leg - limits capacitive switching loss in high-frequency (>200 kHz) topologies |
| dv/dt rating | 10,000 V/μs - resists false triggering in noisy industrial power environments |
Pinout & Package
Package: D-PAK (TO-252AA), surface-mount, with exposed thermal pad on underside for PCB heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode 1) | First anode connection | Connects to first input/output rail; used independently in dual-output configurations |
| 2 (Cathode Common) | Shared cathode node | Single low-impedance return path for both diode legs; ties to system ground or output rail |
| 3 (Anode 2) | Second anode connection | Connects to second input/output rail; enables center-tap transformer or split-rail rectification |
| 4 (Tab / Exposed Pad) | Thermal and electrical ground | Must be soldered to large copper pour for thermal conduction; electrically connected to Cathode (Pin 2) |

| AEC-Q101 qualified | Validated for automotive powertrain and body electronics applications requiring robustness to thermal cycling and humidity |
Applications
| Switching Power Supplies | Battery Charging Systems |
|---|---|
Use Scenario: Secondary-side rectification in 24–48 V output AC/DC adapters and telecom PSUs. IC Role / Device Role / Timing Role: Dual-leg Schottky rectifier replacing two discrete diodes in center-tapped transformer topology. Use Value: 0.65 V VF at 3 A reduces conduction loss by 1.95 W per leg versus 1 V Si diodes, lowering heatsink requirements. |
Use Scenario: Onboard Li-ion or lead-acid battery chargers in portable medical devices and UPS systems. IC Role / Device Role / Timing Role: Reverse-polarity protection and charge-path rectification in dual-input (AC + DC) charging circuits. Use Value: 60 V VRRM accommodates 56 V max float voltage for 48 V battery banks; low IRM (<0.1 mA @ 25°C) prevents standby drain. |
| DC/DC Converters | Reverse Battery Protection |
Use Scenario: Synchronous rectification in isolated 12 V → 3.3 V/5 V buck-derived converters for industrial controllers. IC Role / Device Role / Timing Role: Center-tap configuration interfaces directly with transformer secondary windings for low-loss energy transfer. Use Value: 145 pF CT minimizes switching loss at 300 kHz operation; 10,000 V/μs dv/dt rating suppresses false turn-on in noisy environments. |
Use Scenario: Input protection in automotive infotainment and ADAS modules powered from vehicle battery. IC Role / Device Role / Timing Role: Low-VF series blocking element preventing damage during accidental reverse connection. Use Value: 0.65 V VF yields <1.5 W dissipation at 6 A fault current - significantly lower than MOSFET-based solutions requiring gate drive. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS660CT | Same 6 A/60 V rating, but VF = 0.72 V @ 3 A (25°C); TO-252 package with identical pinout | Slightly higher conduction loss at elevated temperature; not AEC-Q101 qualified | Preferred where cost sensitivity outweighs thermal margin or automotive qualification |
| SS56 | 6 A/60 V, VF = 0.75 V @ 3 A, DO-214AB package - no center tap, single-diode configuration | Requires two devices and additional PCB routing for dual-leg function; lacks common-cathode advantage | Used when board layout permits discrete placement and thermal constraints allow higher VF |
Compared with STPS660CT and SS56, the MBRD660CTTRL delivers lower forward voltage at high temperature, integrated center-tap functionality, and AEC-Q101 qualification - making it optimal for space-constrained, thermally demanding, and automotive-grade rectification tasks.

FAQ
What is the maximum junction temperature rating for the MBRD660CTTRL?
The MBRD660CTTRL has a maximum junction temperature range of –40°C to +150°C, verified per Vishay Bulletin PD-20755 rev. E. This wide operating range supports deployment in under-hood automotive environments and sealed industrial enclosures where ambient temperatures exceed 85°C. Derating curves in Figure 5 confirm sustained 6 A operation at case temperatures up to 128°C with 50% duty cycle.
Is the MBRD660CTTRL pin-compatible with the MBRD650CT?
Yes, the MBRD660CTTRL is mechanically and electrically pin-compatible with the MBRD650CT - both use identical D-PAK (TO-252AA) outlines and share the same 1-Anode1 / 2-Cathode / 3-Anode2 / 4-Tab pin assignment. The only difference is VRRM: 60 V for MBRD660CTTRL versus 50 V for MBRD650CT, allowing direct substitution where higher reverse voltage margin is required.
Does the MBRD660CTTRL require a heatsink in typical 6 A applications?
The MBRD660CTTRL can operate at 6 A without an external heatsink when mounted on ≥2 in² of 2-oz copper with thermal vias to inner layers, thanks to its 6°C/W RthJC and low 0.65 V VF. However, for continuous 6 A operation in ambient temperatures above 60°C or in enclosed spaces, a small clip-on heatsink or increased copper area is recommended to maintain TJ ≤150°C per Figure 5 derating data.
What does "TRL" signify in the part number MBRD660CTTRL?
In MBRD660CTTRL, "TRL" indicates Tape & Reel packaging with left-oriented device placement per Vishay's ordering code table. This orientation aligns the cathode (Pin 2) toward the feed direction's left edge, ensuring correct pick-and-place registration during automated assembly. Each reel contains 2,000 pieces, compatible with standard SMT feeders.
How does the guard ring in the MBRD660CTTRL improve reliability?
The guard ring in the MBRD660CTTRL surrounds the active Schottky junction to suppress edge-related electric field crowding, thereby preventing premature avalanche breakdown during high dv/dt transients or reverse-biased surges. This structure extends operational lifetime in applications like motor drives and automotive start-stop systems where repetitive voltage spikes occur, and is confirmed in Vishay's AEC-Q101 qualification testing.
