Product details
Overview
MBRAD10150H from Taiwan Semiconductor is a 10 A, 150 V Schottky barrier rectifier in ThinDPAK package, designed for low-loss freewheeling and reverse battery protection in automotive DC/DC converters. It features 200 A surge capability, 0.83 V forward voltage at 10 A/25°C, and AEC-Q101 qualification for under-hood use.
For engineers reviewing the MBRAD10150H datasheet, MBRAD10150H pinout, MBRAD10150H application, or MBRAD10150H equivalent, key selection criteria include junction-to-lead thermal resistance (2.5 °C/W), moisture sensitivity level 1 compliance, and cathode-band polarity marking - all critical for high-reliability automotive power design.
Technical Context
This Schottky rectifier uses a single-die construction optimized for high-frequency switching in automotive-grade power conversion. Its 150 V repetitive peak reverse voltage and 10 A average forward current rating support operation in 12 V/24 V battery systems with transient overvoltage tolerance.
The device delivers low conduction loss via a low 0.71 V typical forward voltage at 10 A and 125°C, while its 165 pF junction capacitance at 4 V enables efficient performance in inverter and freewheeling topologies up to several hundred kHz.

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-10BQ150-M3/45 | Same 10 A/150 V rating; VF = 0.82 V @ 10 A/25°C; RθJA = 15 °C/W (vs. 13 °C/W for MBRAD10150H) | Higher thermal resistance requires larger PCB copper area for equivalent power handling | Select when existing layout uses DO-214AB footprint and board rework is not feasible |
| ON Semiconductor SB10150T3G | Identical ThinDPAK package; VF = 0.85 V @ 10 A/25°C; IFSM = 175 A (vs. 200 A) | Lower surge rating may require derating in high-inductance motor drive applications | Select when supply chain diversification is prioritized and 175 A surge margin is sufficient |
Compared with VS-10BQ150-M3/45 and SB10150T3G, the MBRAD10150H offers superior thermal performance (2.5 °C/W RθJL) and higher surge robustness (200 A), making it preferred for thermally constrained automotive modules requiring long-term reliability under repeated transients.

FAQ
What is the maximum junction temperature rating for the MBRAD10150H?
The MBRAD10150H has a maximum junction temperature (TJ max) of +150 °C, validated per AEC-Q101 stress testing. This allows operation in under-hood environments up to +105 °C ambient when properly mounted on ≥25 mm² 2 oz copper thermal pad, with forward current derated linearly above +25 °C case temperature. The MBRAD10150H maintains stable electrical characteristics across this full range.
Is the MBRAD10150H suitable for reverse battery protection in 24 V systems?
Yes, the MBRAD10150H is explicitly rated for reverse battery protection in 24 V automotive systems. Its 150 V repetitive peak reverse voltage exceeds the -150 V requirement of ISO 16750-2 Pulse 4a, and its 2 mA max reverse leakage at 125°C ensures minimal standby current draw. The MBRAD10150H's cathode band marking simplifies correct orientation during automated placement.
Does the MBRAD10150H require moisture preconditioning before reflow soldering?
No, the MBRAD10150H has a moisture sensitivity level (MSL) of 1 per J-STD-020, meaning it can be stored indefinitely at ≤30 °C/60% RH and placed directly into reflow without baking. This eliminates process steps and reduces risk of popcorning during lead-free reflow, supporting high-yield SMT manufacturing. The MBRAD10150H's matte tin plating also ensures reliable solder wetting per J-STD-002.
What is the thermal resistance from junction to lead (RθJL) for the MBRAD10150H?
The MBRAD10150H has a typical junction-to-lead thermal resistance (RθJL) of 2.5 °C/W when mounted on an ideal heat sink, as specified in the thermal performance table. This value reflects conduction through the exposed cathode tab into PCB copper, enabling >8 W power dissipation with appropriate thermal pad design. The MBRAD10150H's low RθJL is a key differentiator versus alternatives with higher values.
How does the forward voltage of the MBRAD10150H vary with temperature?
The MBRAD10150H exhibits negative temperature coefficient behavior: VF decreases as junction temperature rises - e.g., 0.83 V max at 10 A/25°C drops to 0.75 V max at 10 A/125°C. This improves efficiency at elevated temperatures but requires thermal design to avoid runaway in parallel configurations. The MBRAD10150H's VF spec is guaranteed across the full -55°C to +150°C operating range.
