Taiwan Semiconductor Corporation MBR1690HC0G

Overview

MBR1690HC0G from Taiwan Semiconductor is a 16A, 90V AEC-Q101-qualified Schottky barrier rectifier in TO-220AC package, featuring 0.85V max forward voltage at 16A/25°C, 150A surge capability, and guard ring overvoltage protection for automotive-grade power conversion.

For engineers reviewing the MBR1690HC0G datasheet, MBR1690HC0G pinout, MBR1690HC0G application, or MBR1690HC0G equivalent, this device supports high-efficiency SMPS, DC-DC converters, and adapter designs where low conduction loss, thermal robustness (R_θJC = 3°C/W), and AEC-Q101 reliability are critical selection criteria.

Technical Context

This single-die Schottky rectifier operates with unidirectional conduction and zero recovery time, eliminating switching losses typical of PN-junction diodes. Its guard ring structure enhances ruggedness against transient overvoltage events, while the matte tin-plated TO-220AC leads ensure J-STD-002 solderability.

The device sustains continuous forward current up to 16A at case temperature ≤75°C, derates linearly to zero at 150°C junction temperature, and withstands 10,000 V/µs voltage transients-enabling stable operation in fast-switching topologies like synchronous rectification and flyback converters.

FAQ

What is the maximum junction temperature rating for MBR1690HC0G?

The MBR1690HC0G has a maximum junction temperature (T_J) of +150°C, verified per AEC-Q101 stress testing. This allows operation in under-hood automotive environments and high-ambient industrial settings. Derating begins above 75°C case temperature, and thermal design must maintain T_J ≤150°C under worst-case load and ambient conditions. The MBR1690HC0G's R_θJC of 3°C/W supports this with appropriate heatsinking.

Is MBR1690HC0G pin-compatible with standard TO-220AC rectifiers?

Yes, MBR1690HC0G uses the industry-standard TO-220AC outline with anode–cathode–tab pinout and 2.54 mm lead spacing. It mates with standard TO-220AC sockets and PCB footprints. No layout changes are needed when replacing legacy TO-220AC Schottky or FRD rectifiers, provided thermal and electrical margins are validated. The MBR1690HC0G's marking "MBR1690" and "G" suffix confirm green/halogen-free and AEC-Q101 status.

Does MBR1690HC0G support high-frequency switching applications?

Yes, MBR1690HC0G supports high-frequency switching due to its zero reverse recovery time and 10,000 V/µs dV/dt rating. It is commonly used in 100–500 kHz SMPS and DC-DC converters where fast switching minimizes losses. The device's low junction capacitance (<200 pF at 4V) and guard ring design prevent oscillation and snap-off during hard commutation. MBR1690HC0G delivers stable performance without snubbers in properly laid-out layouts.

What does the "H" and "C0G" suffix mean in MBR1690HC0G?

In MBR1690HC0G, "H" indicates AEC-Q101 qualification per JESD22-A108, and "C0G" denotes halogen-free (IEC 61249-2-21) and RoHS-compliant green compound packaging. The "G" also confirms UL 94V-0 flammability rating. These suffixes are factory-coded and appear in the device marking. MBR1690HC0G thus satisfies both automotive reliability and environmental compliance mandates without requiring additional certification documentation.

How does MBR1690HC0G's forward voltage compare at elevated temperatures?

MBR1690HC0G's forward voltage decreases with rising junction temperature: it is 0.85V max at 16A/25°C and drops to 0.75V max at 16A/125°C. This negative temperature coefficient improves thermal stability in parallel configurations and reduces conduction loss at high ambient temperatures. The MBR1690HC0G's consistent V_F behavior across –55°C to +150°C ensures predictable power loss modeling in thermal simulations.
