Product details

Overview

MBRF8100CT from Taiwan Semiconductor is a dual-die Schottky barrier rectifier in ITO-220AB package, rated for 8 A average forward current, 100 V repetitive peak reverse voltage, and 150 A surge current, with 0.85 V typical forward voltage at 4 A and 25°C - used in high-efficiency DC/DC converters and industrial SMPS.

For engineers reviewing the MBRF8100CT datasheet, MBRF8100CT pinout, MBRF8100CT application, or MBRF8100CT equivalent, key selection factors include its 100 V V_RRM, dual-common-cathode configuration, 6 °C/W junction-to-case thermal resistance, AEC-Q101 qualification option (H suffix), and compatibility with high-frequency switching topologies requiring low conduction loss.

Technical Context

This dual-diode Schottky rectifier integrates two independent anodes sharing a common cathode terminal, enabling full-wave rectification or parallel current handling in compact layouts. Its guard ring structure provides overvoltage protection, and the matte tin-plated leads meet J-STD-002 solderability standards.

Designed for operation from –55°C to +150°C junction temperature, it delivers 100 µA max reverse leakage at 25°C and 5 mA at 125°C under rated 100 V reverse bias, with 10,000 V/µs critical dv/dt rating ensuring robustness against fast transients in switching circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum non-repetitive reverse voltage the device blocks without breakdown
I_F	8 A - continuous average forward current per diode at case temperature ≤75°C
I_FSM	150 A - peak non-repetitive surge current (8.3 ms half-sine) the device withstands
V_F @ 4 A, 25°C	0.85 V - forward voltage drop per diode, directly determining conduction loss in power stage
R_θJC	6 °C/W - thermal resistance from junction to case, defining heatsink sizing requirement
T_J max	+150°C - maximum allowable junction temperature, setting thermal derating limits
I_R @ 100 V, 125°C	5 mA - reverse leakage per diode at elevated temperature and full rated voltage

FAQ

What is the maximum junction temperature rating for the MBRF8100CT?

The MBRF8100CT has a maximum junction temperature (T_J) of +150°C, allowing operation in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations. This rating is maintained across its full current and voltage operating range, provided thermal design respects the 6 °C/W junction-to-case resistance and mounting torque does not exceed 0.56 N·m.

Does the MBRF8100CT have AEC-Q101 qualification?

The standard MBRF8100CT is not AEC-Q101 qualified, but the MBRF8100CTH variant - with identical electrical and mechanical specifications - is fully AEC-Q101 qualified per Version J2105 documentation. The 'H' suffix denotes automotive-grade screening and test compliance, making MBRF8100CTH suitable for body electronics and infotainment power supplies.

What is the forward voltage of the MBRF8100CT at 8 A and 125°C?

The MBRF8100CT datasheet specifies forward voltage only at 4 A and 25°C (0.85 V typ). At 8 A and 125°C, V_F increases due to temperature and current effects; extrapolation from Fig.4 Typical Forward Characteristics shows ≈1.05–1.12 V. For precise system loss modeling, use the curve data or contact Taiwan Semiconductor for application-specific characterization of MBRF8100CT.

Can the MBRF8100CT replace the MBRF860CT in an existing design?

Yes, the MBRF8100CT can replace the MBRF860CT if the circuit operates below 100 V reverse voltage and thermal margins accommodate the slightly higher V_F (0.85 V vs. 0.70 V). However, the MBRF8100CT's higher V_RRM adds margin but does not reduce conduction loss - verify layout thermal relief and ensure the 100 V rating aligns with system overvoltage protection requirements before substitution.

What is the marking code for the MBRF8100CT on the device body?

The MBRF8100CT is marked "MBRF8100CT" on the device body per the official marking diagram in Version J2105 documentation. Additional markings include date code (YWW format), factory code (F), and green compound indicator (G), all conforming to ITO-220AB package standards defined by Taiwan Semiconductor.
