Product details

Overview

MBR1660 from Diodes Incorporated is a 16A, 60V Schottky barrier rectifier in TO-220AC package, designed for low-voltage, high-frequency power conversion. It delivers 0.57V forward voltage at 16A and 125°C, supports 150A non-repetitive surge current, and features guard-ring die construction for transient protection-used in DC-DC converter output stages and polarity protection circuits.

For engineers reviewing the MBR1660 datasheet, MBR1660 pinout, MBR1660 application, or MBR1660 equivalent, key selection criteria include forward voltage drop at full load, thermal resistance (1.5°C/W junction-to-case), peak reverse voltage margin, surge capability under inductive switching, and RoHS-compliant tin-plated terminals for lead-free reflow compatibility.

Technical Context

The MBR1660 employs a planar Schottky barrier chip with integrated guard ring to suppress edge leakage and improve transient robustness. Its low V_F (0.57V @ 16A/125°C) minimizes conduction loss in high-current, low-voltage outputs such as 5V/12V server VRMs and industrial SMPS secondary-side rectification.

Thermal performance is optimized for heatsink-mounted operation: R_θJC = 1.5°C/W enables sustained 16A average current at T_C = 125°C. Capacitance (450pF @ 4V, 1MHz) and dV/dt rating (1000–10,000 V/s) support fast-switching flyback and synchronous rectifier auxiliary roles.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	60 V - Maximum repetitive reverse blocking voltage; sets safe operating limit in 48V system inputs or 36V battery backup rails.
I_O	16 A @ T_C = 125°C - Continuous DC output current capacity when case temperature is maintained at 125°C via heatsink.
V_FM	0.57 V @ I_F = 16A, T_C = 125°C - Confirmed conduction loss per device; determines efficiency impact in parallel or single-device 12V/15A outputs.
I_FSM	150 A (8.3ms half-sine) - Withstands inrush and short-circuit surge without bond-wire fusing in UPS or motor drive freewheeling paths.
R_θJC	1.5 °C/W - Enables thermal design with standard TO-220 heatsinks; 10°C rise per 6.7W dissipation at full load.
C_T	450 pF @ 4V, 1MHz - Limits high-frequency ringing in >100kHz converters; impacts EMI filter sizing in compact adapters.

Pinout & Package

Package: TO-220AC - 3-lead, single-ended vertical mounting package with isolated tab (cathode-connected), rated for 125°C case operation and UL 94V-0 flammability compliance.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Anode)	Anode connection	Input terminal for forward conduction; connects to transformer secondary or switch node in freewheeling path.
Pin 2 (Cathode)	Cathode connection	Output terminal; electrically tied to metal tab-must be insulated from chassis if cathode is not ground-referenced.
Tab (Cathode)	Common cathode terminal	Primary heat path and electrical cathode node; requires insulating washer when mounted to grounded heatsink.

Key Features

Feature	Design Value
Guard-ring die construction	Suppresses edge leakage and improves dv/dt immunity-critical for reliability in noisy industrial inverters.
Low V_F at high temperature	0.57V @ 125°C enables stable efficiency in thermally constrained enclosures without derating.
150A surge rating	Supports repeated cold-start surges in telecom power supplies without parametric shift or failure.
RoHS-compliant bright tin finish	Ensures solder joint integrity under lead-free reflow profiles (peak 260°C) without whisker risk.

Applications

DC-DC Converter Output Rectification

Polarity Protection Circuit

Use Scenario: Secondary-side rectification in 12V/15A isolated flyback or forward converter for industrial PLC power modules.

IC Role / Device Role / Timing Role: Uncontrolled rectifier conducting during transformer reset phase; replaces diode in synchronous rectifier auxiliary path.

Use Scenario: Reverse-voltage blocking in 24V DC input stage of factory automation I/O module.

IC Role / Device Role / Timing Role: Series-connected anode-in configuration preventing damage from accidental battery reversal or field wiring error.

Use Value: 60V V_RRM provides 2× margin over 24V nominal rail, ensuring survival during load dump transients up to 40V.

Freewheeling Diode in Motor Drive

Low-Voltage Inverter Output Stage

Use Scenario: Freewheeling path for 16A H-bridge gate driver supply in servo amplifier feedback loop.

IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during PWM off-time to maintain gate bias stability.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-MBR1660CT	TO-220AB package (dual-diode center-tap); 0.60V V_F @ 16A/25°C; same V_RRM, higher IR_M (0.5mA @ 25°C).	Requires dual-output or center-tapped transformer; unsuitable for single-anode freewheeling use.	Select only when dual-diode topology matches schematic and layout constraints.
ON Semiconductor MBR1660G	Same TO-220AC package; 0.62V V_F @ 16A/25°C; slightly higher R_θJC (1.7°C/W); identical surge rating.	Compatible pinout and thermal interface; validated in legacy telecom PFC front-end designs.	Prefer for cross-supply continuity where ON Semi BOMs already exist and 0.05V V_F penalty is acceptable.

Compared with MBR1660, VS-MBR1660CT offers dual-diode integration but sacrifices single-device flexibility, while MBR1660G trades marginal V_F increase for broader qualification history in telecom infrastructure-making Diodes' version optimal for new designs prioritizing lowest conduction loss at elevated temperature.

FAQ

Is MBR1660 suitable for surface-mount assembly?

No. The MBR1660 uses a through-hole TO-220AC package with leads designed for wave or hand soldering. It lacks SMD-compatible footprint or thermal pad structure. For SMT alternatives, consider Diodes' AP1660 (PowerDI5060) or Vishay's V16P60M, both rated 16A/60V in surface-mount packages.

What is the maximum recommended case temperature for continuous 16A operation?

The datasheet specifies I_O = 16A at T_C = 125°C. Operation above this temperature requires current derating per Figure 1: at 135°C case, max I_O drops to ~14.5A. Thermal design must ensure heatsink interface resistance keeps T_C ≤ 125°C under worst-case ambient and airflow conditions.

Does MBR1660 have avalanche rating?

No. As a Schottky rectifier, the MBR1660 lacks controlled avalanche capability. It relies on external clamping (e.g., TVS or RC snubber) for inductive switching transients exceeding its 60V V_RRM. Its guard-ring construction improves ruggedness but does not confer rated avalanche energy absorption.

Can MBR1660 replace a 1N5822 in a 3A/40V application?

Yes, but with significant overspecification: MBR1660 handles 16A/60V versus 1N5822's 3A/40V. Benefits include lower V_F (0.57V vs. ~0.55V at 3A), higher surge tolerance (150A vs. 80A), and superior thermal robustness. However, cost and board space may favor direct 1N5822 replacement unless future current scaling is planned.
