Product details

Overview

MBR1690 C0G from Taiwan Semiconductor is a 16A, 90V Schottky barrier rectifier in TO-220AC package, featuring low forward voltage (0.85 V at 16 A, 25°C), high surge current capability (150 A), and junction-to-case thermal resistance of 3°C/W. It serves as primary output rectifier in high-efficiency DC/DC converters and industrial SMPS.

For engineers reviewing the MBR1690 C0G datasheet, MBR1690 C0G pinout, MBR1690 C0G application, or MBR1690 C0G equivalent, this page delivers verified electrical parameters, thermal performance data, AEC-Q101 qualification status, and direct alternative part comparisons for power supply design validation and component selection.

Technical Context

The MBR1690 C0G uses a single-die Schottky structure with guard ring overvoltage protection and matte tin-plated leads compliant with J-STD-002. Its 90 V repetitive peak reverse voltage (V_RRM) and 63 V RMS reverse voltage support mid-range industrial and automotive auxiliary power rails.

With maximum junction temperature of 150°C and thermal resistance R_θJC = 3°C/W, the device sustains continuous 16 A conduction under forced-air or heatsink-cooled conditions. Reverse leakage remains ≤300 µA at 25°C and ≤7.5 mA at 125°C, enabling stable operation in thermally demanding environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	90 V - Supports 48 V–72 V nominal input systems with 25% safety margin
I_F	16 A continuous - Delivers full-rated output current without derating up to T_C = 80°C
V_F	0.85 V max at 16 A, 25°C - Reduces conduction loss to ≤13.6 W per device in 12 V output stage
I_FSM	150 A peak (8.3 ms half-sine) - Withstands cold-start surges and transient load steps
R_θJC	3°C/W - Enables compact heatsink design; ΔT = 48°C rise at 16 A conduction
T_J max	150°C - Compatible with under-hood automotive ambient and industrial enclosure temperatures
I_R	≤300 µA @ 90 V, 25°C - Minimizes standby power loss in energy-sensitive adapters

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-MBR1690CT	TO-220AB dual common-cathode configuration; 0.82 V V_F typ at 16 A; 120 A I_FSM	Requires dual-output or parallel rectification layout; not single-anode replacement	Select only when dual-cathode topology matches existing PCB footprint and thermal design
ON Semiconductor MBR1690CT	TO-220AB package; 0.84 V V_F max at 16 A; 125 A I_FSM	Same pinout but different thermal path - tab is isolated, requiring separate cathode trace routing	Choose when isolation between cathode and tab is required for floating ground schemes

Compared with MBR1690 C0G, VS-MBR1690CT offers lower typical V_F but mandates dual-diode layout changes, while MBR1690CT provides tab isolation at the cost of 25 A lower surge rating - both require mechanical and thermal revalidation despite shared voltage/current ratings.

FAQ

What is the maximum junction temperature rating for MBR1690 C0G?

The MBR1690 C0G has a maximum junction temperature (T_J) of +150°C, validated across its full operating range. This rating enables reliable operation in enclosed industrial enclosures and under-hood automotive environments where case temperatures may reach 105°C. Derating curves confirm 16 A continuous current is sustainable up to 80°C case temperature, making MBR1690 C0G suitable for thermally aggressive deployments without active cooling.

Does MBR1690 C0G meet automotive qualification standards?

Yes - the MBR1690H variant is AEC-Q101 qualified, undergoing stress testing for temperature cycling, humidity, and mechanical shock per automotive reliability standards. The base MBR1690 C0G shares identical die and packaging but lacks formal AEC-Q101 certification documentation. For automotive applications requiring certified components, specify MBR1690H; for industrial use, MBR1690 C0G delivers identical electrical and thermal performance.

What is the forward voltage specification of MBR1690 C0G at elevated temperature?

At 16 A and junction temperature of 125°C, the MBR1690 C0G exhibits a maximum forward voltage (V_F) of 0.75 V. This represents a 11.8% reduction from its 25°C value (0.85 V), confirming stable conduction behavior across temperature. The lower V_F at high T_J improves efficiency in thermally saturated designs and reduces thermal runaway risk in paralleled configurations.

Is the metal tab of MBR1690 C0G electrically isolated?

No - the metal tab of MBR1690 C0G is internally connected to the cathode terminal (Lead 2). This TO-220AC configuration requires electrical isolation of the heatsink from system ground unless the cathode node is referenced to chassis. PCB layout must assign the tab pad to the cathode net and avoid accidental shorting to adjacent grounded planes or shields.

How does MBR1690 C0G compare to MBR16100 in terms of reverse leakage current?

At 25°C and rated 90 V reverse voltage, MBR1690 C0G specifies ≤300 µA reverse leakage (I_R), whereas MBR16100 (100 V rating) specifies ≤300 µA at 100 V. At 125°C, MBR1690 C0G leakage rises to ≤7.5 mA - identical to MBR16100's 125°C rating. Both devices use the same process technology; the 90 V version trades margin for slightly better leakage at room temperature, benefiting low-standby-power adapter designs.
