Product details
Overview
MBR1660 from Taiwan Semiconductor is a 16A, 60V Schottky barrier rectifier in TO-220AC package, designed for high-efficiency DC/DC conversion and SMPS output stages. It delivers low forward voltage (0.75 V at 16 A, 25°C), high surge capability (150 A IFSM), and operates up to 150°C junction temperature.
For engineers reviewing the MBR1660 datasheet, MBR1660 pinout, MBR1660 application, or MBR1660 equivalent, key selection criteria include its 60 V VRRM rating, 0.75 V VF at rated current, 3 °C/W RθJC thermal resistance, AEC-Q101 qualification availability, and TO-220AC mechanical compatibility with standard heatsink mounting.
Technical Context
This single-die Schottky rectifier uses a guard ring structure for overvoltage protection and supports high-frequency switching due to low junction capacitance and fast recovery (dV/dt = 10,000 V/µs). Its 150 A non-repetitive surge rating enables robust operation during power-up transients in industrial adapters.
The device exhibits 10 mA reverse leakage at 125°C and 60 V, and derates linearly from 16 A at 25°C case temperature to ~8 A at 100°C - critical for thermal design in enclosed power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 48 V system outputs. |
| IF | 16 A - Continuous average forward current; sets minimum heatsink sizing for sustained load conditions. |
| VF @ 16A, 25°C | 0.75 V - Forward voltage drop; directly determines conduction loss (12 W at full load) and efficiency impact. |
| IFSM | 150 A - Peak non-repetitive surge current; withstands inrush in switch-mode supplies without failure. |
| RθJC | 3 °C/W - Junction-to-case thermal resistance; enables accurate thermal modeling when mounted to heatsink. |
| TJ max | 150 °C - Maximum junction temperature; allows operation in high-ambient industrial environments. |
| IR @ 60V, 125°C | 10 mA - Reverse leakage current; impacts standby power and thermal runaway risk in parallel configurations. |
Pinout & Package
Package: TO-220AC - 3-lead through-hole package with isolated tab (cathode-connected), matte tin-plated leads, UL 94V-0 molding compound, and 0.56 N·m maximum mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction | Connected to lower-potential side (e.g., transformer secondary center-tap or buck converter switch node). |
| Cathode | Output terminal for forward conduction | Electrically tied to metal tab; must be isolated from chassis unless circuit ground reference permits. |
| Tab (Cathode) | Thermal and electrical cathode connection | Primary heat path to heatsink; requires insulating washer if mounted to grounded metal enclosure. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring overvoltage protection | Enhances ruggedness against transient voltage spikes without external snubbers in 48 V bus applications. |
| AEC-Q101 qualified version available | Supports automotive-grade reliability requirements (e.g., infotainment power rails, body control modules). |
| Low forward voltage (0.75 V @ 16 A) | Reduces conduction losses by ~15% vs. comparable 60 V Si diodes, improving 12–48 V DC/DC efficiency. |
| High surge current capability (150 A) | Enables use in high-inrush designs like server PSUs without series fusing or oversized traces. |
| RoHS & halogen-free compliance | Fulfills IPC/JEDEC environmental standards for industrial and consumer end-equipment manufacturing. |
Applications

IC Role / Device Role / Timing Role: Low-noise, low-leakage output rectifier minimizing EMI and standby current. Use Value: 10 mA IR at 125°C prevents thermal runaway in sealed enclosures, supporting long-term reliability testing. |
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 | Center-tap dual die in TO-220AB; 0.72 V VF @ 16 A, 25°C; 120 A IFSM. | Requires dual-output or center-tapped transformer topology; not single-anode/cathode compatible. | Select only when dual-output architecture is used; not a drop-in replacement for MBR1660's single-diode configuration. |
| ON Semiconductor MBR1660G | Same 60 V VRRM, 16 A IF, TO-220AC; 0.74 V VF @ 16 A, 25°C; AEC-Q101 qualified as standard. | Identical pinout and thermal profile; differs in qualification status and minor VF tolerance. | Preferred for automotive programs requiring pre-qualified AEC-Q101 parts without custom ordering suffixes. |
Compared with MBR1660, VS-MBR1660CT serves dual-output topologies but lacks single-diode compatibility, while MBR1660G offers identical form-factor and performance with built-in AEC-Q101 qualification - simplifying automotive BOM validation without sacrificing thermal or electrical behavior.

FAQ
What is the maximum junction temperature rating for MBR1660?
The MBR1660 has a maximum junction temperature (TJ max) of 150°C. This rating allows reliable operation in high-ambient environments such as enclosed industrial power supplies or under-hood automotive applications. Thermal design must ensure that actual junction temperature remains below this limit under worst-case load and ambient conditions, using the specified 3 °C/W RθJC value and appropriate heatsinking.
Is MBR1660 pin-compatible with other parts in the MBR16xx series?
Yes, all MBR16xx devices including MBR1660 share the same TO-220AC package, pinout, and mechanical footprint. Anode, cathode, and tab connections are identical across the series - enabling board-level voltage scalability (e.g., swapping MBR1660 for MBR16100) without layout changes, provided thermal and electrical margins are re-verified.
Does MBR1660 have AEC-Q101 qualification?
The base MBR1660 is not AEC-Q101 qualified; however, the AEC-Q101 variant is offered as MBR1660H per Taiwan Semiconductor's ordering code. This version undergoes additional stress testing for automotive applications and carries the "H" suffix. Designers requiring automotive qualification must specify MBR1660H - the standard MBR1660 does not meet AEC-Q101 requirements.
What is the forward voltage of MBR1660 at elevated temperature?
At 16 A and 125°C junction temperature, the MBR1660 exhibits a typical forward voltage (VF) of 0.65 V - lower than its 0.75 V value at 25°C due to the negative temperature coefficient of Schottky diodes. This reduction improves conduction efficiency at high operating temperatures but requires verification of thermal stability in parallel configurations.
How is the cathode terminal connected in the TO-220AC package of MBR1660?
In the MBR1660 TO-220AC package, the metal tab is electrically connected to the cathode terminal. The two leads are anode (pin 1) and cathode (pin 2); the tab serves as a second cathode connection and primary thermal path. When mounting to a heatsink, electrical isolation (e.g., mica washer + shoulder washer) is required unless the cathode is referenced to system ground.
