Taiwan Semiconductor Corporation MBR1660HC0G

Overview

MBR1660HC0G from Taiwan Semiconductor is a 16A, 60V AEC-Q101-qualified Schottky barrier rectifier in TO-220AC package, featuring 0.75V max forward voltage at 16A/25°C, 150A surge current capability, and guard ring overvoltage protection-used in automotive-grade DC-DC converters and industrial SMPS.

For engineers reviewing the MBR1660HC0G datasheet, MBR1660HC0G pinout, MBR1660HC0G application, or MBR1660HC0G equivalent, key selection criteria include its 60V V_RRM, 3°C/W junction-to-case thermal resistance, AEC-Q101 qualification status, low VF for high-efficiency power conversion, and TO-220AC mechanical compatibility with standard heatsink mounting.

Technical Context

This single-die Schottky rectifier operates with a maximum junction temperature of 150°C and supports repetitive peak reverse voltages up to 60V. Its 150A non-repetitive surge rating (8.3ms half-sine) and 10,000 V/µs dV/dt rating enable robust operation in switching transients.

The device delivers 0.65V typical forward voltage at 16A and 125°C, enabling stable performance under elevated thermal conditions. Reverse leakage remains ≤10mA at 125°C and rated VR, supporting reliable blocking in high-temperature power stages.

FAQ

What does the 'H' and 'C0G' suffix mean in MBR1660HC0G?

The 'H' suffix indicates AEC-Q101 qualification per JESD22-A108 stress testing. 'C0G' denotes green compound (halogen-free per IEC 61249-2-21) and date code format (YWW). MBR1660HC0G is therefore an automotive-grade, environmentally compliant variant of the MBR1660 series with full traceability and reliability validation.

Is MBR1660HC0G pin-compatible with standard TO-220AC rectifiers?

Yes, MBR1660HC0G uses the industry-standard TO-220AC outline with anode–cathode–tab pinout and 2.54 mm lead pitch. It mates with standard TO-220AC sockets and heatsinks. The tab is cathode-connected, requiring electrical isolation if mounted to a grounded heatsink-consistent with all TO-220AC Schottky rectifiers.

What is the maximum junction temperature and how does it affect MBR1660HC0G derating?

MBR1660HC0G has a maximum junction temperature of 150°C. At 100°C case temperature, its average forward current derates to approximately 10A per the forward current derating curve. This allows sustained 16A operation only when case temperature is maintained ≤75°C via adequate heatsinking-critical for automotive under-hood deployment.

How does the guard ring in MBR1660HC0G improve reliability?

The integrated guard ring in MBR1660HC0G provides edge termination that suppresses premature avalanche breakdown during voltage transients. This enables the device to withstand 10,000 V/µs dV/dt without external snubbers and survive 150A surge events-key for automotive load-dump and industrial motor-drive noise immunity where MBR1660HC0G operates without additional protection circuitry.

Can MBR1660HC0G replace silicon PN rectifiers in existing designs?

Yes, MBR1660HC0G can directly replace 60V/16A silicon rectifiers such as 1N5408 or UF1606 in most cases, delivering lower forward voltage (0.75V vs. ~1.1V), reduced thermal load, and faster recovery. However, verify reverse leakage tolerance-MBR1660HC0G exhibits higher IR (≤500 µA at 25°C) than silicon devices, which may affect ultra-low-power standby circuits.
