Product details
Overview
MBR1650 C0G from Taiwan Semiconductor is a 16A, 50V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage (0.75 V @ 16 A, 25°C), high surge current capability (150 A), and AEC-Q101 qualification option. It serves as primary output rectifier in high-efficiency DC/DC converters and industrial SMPS.
For engineers reviewing the MBR1650 C0G datasheet, MBR1650 C0G pinout, MBR1650 C0G application, or MBR1650 C0G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), junction-to-case thermal resistance (3 °C/W), reverse leakage (500 µA @ 25°C), and compatibility with high-frequency switching topologies requiring low conduction loss.
Technical Context
This single-die Schottky rectifier uses platinum-silicide or similar low-barrier metallization to achieve fast recovery (no stored charge) and minimal reverse recovery time. Its guard ring structure enhances ruggedness against transient overvoltage events common in automotive and industrial power rails.
The device operates across –55°C to +150°C junction temperature range and maintains stable forward voltage drop up to 125°C (0.65 V @ 16 A), enabling reliable performance in thermally constrained enclosures without forced air cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum reverse blocking voltage before breakdown; defines usable input/output voltage margin in 48 V systems |
| IF | 16 A - Continuous average forward current at case temperature ≤ 75°C; sets minimum heatsink requirement |
| IFSM | 150 A - Non-repetitive surge rating for 8.3 ms half-sine; supports inrush current handling in hot-plug circuits |
| VF | 0.75 V @ 16 A, 25°C - Low conduction loss reduces power dissipation by ~12 W vs. silicon diode at same current |
| RθJC | 3 °C/W - Thermal resistance from junction to case; enables direct mounting to chassis or heatsink without thermal interface pads |
| IR | 500 µA @ 50 V, 25°C - Low leakage preserves efficiency in standby mode and high-impedance bias networks |
Pinout & Package
Package: TO-220AC - Three-terminal through-hole package with isolated tab (cathode-connected), matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and 0.56 N·m maximum mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current entry point | Connected to unregulated or higher-potential rail; requires trace width ≥ 2.5 mm for 16 A continuous |
| Cathode | Output current exit point | Internally bonded to metal tab; electrically active and thermally conductive - must be insulated if mounted to grounded heatsink |
| Tab (Case) | Cathode terminal & thermal path | Provides primary heat conduction path; polarity marked on device body; not isolated from cathode |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring structure | Enhances avalanche ruggedness and prevents edge breakdown under transient overvoltage (e.g., load dump in 12 V automotive systems) |
| AEC-Q101 qualification option | Validated for automotive power modules requiring reliability under temperature cycling, mechanical shock, and humidity testing |
| Halogen-free construction | Complies with IEC 61249-2-21; eliminates corrosive halogen emissions during PCB reflow or end-of-life incineration |
| High IFSM/IF ratio (9.4:1) | Supports short-duration overload conditions without bond wire fusing - critical for PFC front-end and motor drive freewheeling paths |

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-MBR1650CT | TO-220AB package (dual common-cathode); 0.72 V VF @ 16 A, 25°C; 125 A IFSM | Requires dual-output or parallel-path designs; not single-diode drop-in replacement | Select when dual-cathode configuration matches existing layout or when lower VF justifies redesign |
| ON Semiconductor MBR1650CT | TO-220AB package; 0.74 V VF @ 16 A, 25°C; 120 A IFSM; no AEC-Q101 option | Lacks automotive qualification; slightly higher thermal resistance (3.5 °C/W) | Prefer for cost-sensitive industrial adapters where AEC-Q101 is unnecessary and thermal margin exists |
Compared with MBR1650 C0G, VS-MBR1650CT offers lower VF but demands dual-cathode circuit adaptation, while MBR1650CT trades AEC-Q101 and thermal performance for broader commercial availability - making MBR1650 C0G optimal for automotive-qualified, single-diode, thermally constrained designs.

FAQ
What is the maximum junction temperature rating for MBR1650 C0G?
The MBR1650 C0G has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating enables operation in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations when properly heatsinked. Derating curves confirm 16 A continuous current is sustainable up to 75°C case temperature.
Does MBR1650 C0G have AEC-Q101 qualification?
Yes, MBR1650 C0G is available in an AEC-Q101-qualified version denoted by the "H" suffix (e.g., MBR1650H). The qualification covers temperature cycling, mechanical shock, and humidity testing per AEC-Q101 Rev D. Standard MBR1650 C0G is not automatically qualified - only variants explicitly ordered with the H suffix meet automotive stress test requirements.
What is the forward voltage of MBR1650 C0G at elevated temperature?
At 16 A and 125°C junction temperature, the MBR1650 C0G exhibits a typical forward voltage of 0.65 V, per electrical specifications in the Taiwan Semiconductor datasheet. This represents a 0.10 V reduction from its 25°C value (0.75 V), confirming positive temperature coefficient behavior typical of Schottky diodes and supporting stable current sharing in parallel configurations.
Is the metal tab of MBR1650 C0G electrically isolated?
No, the metal tab of MBR1650 C0G is not electrically isolated - it is internally connected to the cathode terminal. The TO-220AC package used for MBR1650 C0G features a non-isolated tab, meaning the tab must be either left floating, insulated from the heatsink, or intentionally tied to the cathode net. This differs from TO-220AB or TO-220FP packages which may offer isolation.
What packaging options are available for MBR1650 C0G?
MBR1650 C0G is supplied in TO-220AC package, packed 50 units per tube. No tape-and-reel or tray options are specified in the official Taiwan Semiconductor ordering information. The "C0G" suffix denotes green (halogen-free) compound per IEC 61249-2-21, not capacitor dielectric - it is part of TSC's internal eco-compliance marking convention for this rectifier family.
