Product details
Overview
MBRAD5100H from Taiwan Semiconductor is a 5 A, 100 V Schottky barrier rectifier in ThinDPAK package, designed for low-loss freewheeling and reverse battery protection in automotive DC/DC converters and car lighting systems, with AEC-Q101 qualification and 120 A surge capability.
For engineers reviewing the MBRAD5100H datasheet, MBRAD5100H pinout, MBRAD5100H application, or MBRAD5100H equivalent, key selection factors include forward voltage at 5 A (0.77 V typ @ 25°C), junction-to-lead thermal resistance (2.3 °C/W), TJ max (150°C), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky rectifier uses a single-die construction optimized for high-frequency switching in automotive power supplies. Its low VF (0.63 V max @ 5 A, 125°C) and low CJ (94 pF @ 4 V) minimize conduction and switching losses in DC/DC topologies.
The ThinDPAK package enables high-current handling with low thermal resistance: RθJL = 2.3 °C/W with ideal heatsink and RθJA = 13.6 °C/W on 2" × 3" × 0.25" aluminum plate, supporting continuous 5 A operation under defined board-level cooling conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Continuous Forward Current) | 5 A - supports sustained output current in compact DC/DC converters without forced air cooling |
| VRRM (Repetitive Peak Reverse Voltage) | 100 V - suitable for 48 V automotive systems with margin against load dump transients |
| IFSM (Surge Current, 8.3 ms) | 120 A - withstands inrush and fault currents in reverse battery protection circuits |
| VF (Forward Voltage @ 5 A, 25°C) | 0.77 V max - reduces conduction loss vs. silicon diodes, improving efficiency in high-duty-cycle operation |
| TJ max (Maximum Junction Temperature) | 150 °C - enables operation in under-hood environments per AEC-Q101 stress requirements |
| RθJL (Junction-to-Lead) | 2.3 °C/W - allows direct PCB copper pour heat transfer to chassis or heatsink, critical for thermal management |
| CJ (Junction Capacitance) | 94 pF @ 4 V - limits switching noise and EMI in >100 kHz converter designs |
Pinout & Package
Package: ThinDPAK (JEDEC TO-252 variation AE), surface-mount, matte tin-plated leads, polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Input current terminal | Connected to input rail or inductive switch node; carries full forward current during conduction |
| 2 (Cathode) | Output current terminal | Connected to ground or return path; must be routed over large copper area for thermal dissipation |
| 3 (Exposed Pad / Drain Tab) | Thermal & electrical cathode extension | Internally connected to cathode; soldered to PCB thermal pad to achieve RθJL = 2.3 °C/W performance |
Key Features

Applications
| Automotive DC/DC Converters | Reverse Battery Protection |
|---|---|
Use Scenario: Step-down conversion from 12 V or 48 V battery to 3.3 V/5 V rails in ADAS ECUs and infotainment modules. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous or asynchronous buck converters operating at 200–500 kHz. Use Value: Low VF (0.77 V max @ 25°C) and low CJ (94 pF) reduce power loss and EMI, enabling higher efficiency and smaller filter components. | Use Scenario: Protection circuit placed between battery input and main power distribution in vehicle body control modules. IC Role / Device Role / Timing Role: Unidirectional blocking element that conducts only during correct battery polarity connection. Use Value: 100 V VRRM provides margin against 12 V system load dump spikes (up to ~87 V), while 120 A IFSM handles jump-start surges. |
| Car Lighting Systems | Low-Voltage Inverters |
Use Scenario: LED driver power stage in headlamp and tail lamp assemblies with PWM dimming and thermal foldback. IC Role / Device Role / Timing Role: Output rectifier in boost or buck-boost LED drivers operating up to 150°C ambient. Use Value: TJ max = 150°C and stable VF across temperature ensure consistent light output and lifetime under hood heat exposure. | Use Scenario: High-frequency AC generation for cold-cathode fluorescent lamp (CCFL) backlighting or small motor drives. IC Role / Device Role / Timing Role: Output rectifier in half-bridge or full-bridge inverter output stage. Use Value: Fast recovery (inherent to Schottky) and low stored charge prevent shoot-through and improve waveform fidelity at >20 kHz switching. |
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-50WQ10FN-M3/45 | Same 5 A / 100 V rating; VF = 0.72 V max @ 5 A, 25°C; RθJA = 15 °C/W; TO-220AC package | Through-hole mounting; higher thermal resistance requires heatsink for 5 A continuous use | Preferred where through-hole assembly or legacy footprint compatibility is required |
| ON Semiconductor SB5100-E3/54 | Same 5 A / 100 V rating; VF = 0.82 V max @ 5 A, 25°C; RθJA = 20 °C/W; DO-201AD package | Radial leaded package; lower surge rating (100 A vs. 120 A); no AEC-Q101 qualification | Acceptable for non-automotive industrial DC/DC where cost is prioritized over qualification and surge margin |
Compared with VS-50WQ10FN-M3/45 and SB5100-E3/54, the MBRAD5100H delivers superior thermal performance in surface-mount form (RθJL = 2.3 °C/W), AEC-Q101 qualification for automotive use, and higher surge robustness-making it optimal for space-constrained, high-reliability automotive power stages.

FAQ
What is the marking code for MBRAD5100H?
The MBRAD5100H is marked "5100" on the device body per its ordering information. This two-digit code identifies the voltage rating (100 V) and current rating (5 A) in Taiwan Semiconductor's standard Schottky rectifier marking convention. The full MBRAD5100H part number is not laser-marked; only the "5100" code appears on the ThinDPAK package surface.
Is MBRAD5100H suitable for reverse battery protection in 48 V automotive systems?
Yes, the MBRAD5100H is suitable for reverse battery protection in 48 V systems. Its 100 V VRRM provides adequate margin against typical 48 V load dump transients (≤87 V), and its 120 A IFSM (8.3 ms) handles jump-start surges. AEC-Q101 qualification and TJ max = 150°C further confirm its suitability for under-hood deployment in 48 V architectures.
What is the recommended PCB pad layout for MBRAD5100H?
The MBRAD5100H ThinDPAK package requires an exposed thermal pad (Pin 3) soldered to a minimum 100 mm² copper area on the PCB for optimal thermal performance. Taiwan Semiconductor's suggested pad layout specifies 4.57 mm × 5.92 mm pad dimensions with thermal vias to inner ground planes. Deviation reduces RθJL below the rated 2.3 °C/W and risks thermal derating of IF.
Does MBRAD5100H have a specified reverse recovery time (trr)?
No, the MBRAD5100H does not specify reverse recovery time (trr) because it is a Schottky barrier diode, which operates via majority-carrier conduction and has no minority-carrier storage delay. Instead, its switching behavior is characterized by junction capacitance (CJ = 94 pF @ 4 V) and low forward voltage-key parameters for high-frequency rectification in DC/DC converters.
What is the moisture sensitivity level (MSL) for MBRAD5100H?
The MBRAD5100H has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no baking prior to reflow soldering. This simplifies SMT line integration and eliminates moisture-related popcorning risk during standard lead-free reflow profiles.
