Product details
Overview
B360AX-13 from Diodes Incorporated is a 3A, 60V Trench Schottky barrier rectifier in SMA package, featuring 0.58 V max forward voltage at 3 A and 0.5 mA max reverse leakage at 60 V and +25°C, optimized for high-frequency DC-DC converters and freewheeling applications in industrial power supplies.
For engineers reviewing the B360AX-13 datasheet, B360AX-13 pinout, B360AX-13 application, or B360AX-13 equivalent, key selection criteria include low VF for efficiency, soft switching for EMI control, 150°C junction rating for thermal robustness, and RoHS/Green compliance for modern production.
Technical Context
This Schottky rectifier uses trench-based silicon structure to achieve lower forward voltage and reduced reverse recovery charge versus planar Schottkys, enabling operation up to 1 MHz in switch-mode topologies. Its unidirectional conduction and cathode-band polarity marking define its role as a low-loss output rectifier or freewheeling diode.
Thermal design relies on RθJA = 65°C/W (FR-4 board) and RθJC = 25°C/W, with derating required above +25°C ambient - DC forward current drops to ~1.8 A at +100°C case temperature per Figure 4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse voltage before breakdown; sets safe blocking margin in 48 V DC-DC outputs. |
| IO(AV) | 3 A - Average forward current rating at +25°C ambient; usable up to 1.8 A at +100°C case temp. |
| VF(MAX) | 0.58 V @ 3 A, +25°C - Low conduction loss enables >95% efficiency in 5–12 V output stages. |
| IR(MAX) | 0.5 mA @ 60 V, +25°C - Minimal leakage preserves standby power in always-on systems. |
| TJ(max) | +150°C - Enables operation in sealed enclosures or high-ambient industrial environments. |
| IFSM | 70 A @ 1 ms half-sine - Withstands inrush and transient surges without failure. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic body with matte tin-plated leads, cathode band polarity indicator, moisture sensitivity level 1 (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to lower-potential node (e.g., switch node in buck converter); requires thermal pad layout per Diodes' SMA outline. |
| Cathode | Forward current exit / reverse-blocking terminal | Marked with band; ties to output rail or ground return; carries full load current and must minimize trace inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~0.05–0.1 V vs. planar Schottky, directly improving light-load efficiency in 5–24 V DC-DC stages. |
| Soft, fast switching | Negligible reverse recovery charge (QRR ≈ 0), eliminating switching spikes and reducing snubber losses in high-frequency SMPS. |
| +150°C operating junction | Supports sustained operation in thermally constrained spaces (e.g., enclosed LED drivers or PoE PDs) without derating to <1 A. |
| Halogen- and antimony-free "Green" construction | Meets IEC 61249-2-21 and JEDEC J-STD-70B; eliminates Br/Cl/antimony compounds (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb). |
Applications
| AC-DC Adapter Output Rectification | DC-DC Buck Converter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in 5–24 V, 2–3 A wall adapters using quasi-resonant flyback topology. IC Role / Device Role / Timing Role: Unidirectional output rectifier replacing slower PN diodes to reduce conduction loss and improve efficiency. Use Value: 0.58 V VF cuts rectifier loss by ~40% vs. 1N5822, raising adapter efficiency from 82% to 85.5% at full load. | Use Scenario: Freewheeling path in 12 V input → 3.3 V/3 A synchronous buck regulator running at 500 kHz. IC Role / Device Role / Timing Role: Anti-parallel path for inductor current during high-side FET off-time; critical for continuous conduction mode stability. Use Value: Near-zero QRR prevents voltage overshoot and reduces EMI filtering burden compared to standard Schottkys. |
| Reverse Polarity Protection | Blocking Diode in Solar Charge Controller |
Use Scenario: Series-connected protection in 12 V automotive accessory circuits where battery reversal risk exists. IC Role / Device Role / Timing Role: Forward-conducting series diode blocking reverse current during incorrect battery connection. Use Value: 0.5 mA IR at +85°C ensures <6 µW standby dissipation, preserving battery life over months of idle storage. | Use Scenario: Blocking diode between 18–22 V PV panel and 12 V LiFePO₄ battery bank in off-grid solar charge controller. IC Role / Device Role / Timing Role: Prevents nighttime battery discharge through panel; operates continuously under partial shading and elevated ambient. Use Value: +150°C TJ rating allows reliable operation at +85°C ambient with 25°C rise, avoiding thermal shutdown in rooftop enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS36-E3/57T (Vishay) | Same SMA package, 3 A/60 V, but VF = 0.7 V max @ 3 A - 0.12 V higher than B360AX-13. | Higher conduction loss reduces efficiency in high-duty-cycle DC-DC; acceptable in low-duty freewheeling. | Select when cost priority outweighs 0.3–0.5% system efficiency loss at full load. |
| MBR360FCT (ON Semiconductor) | TO-277A (SMA-equivalent footprint), 3 A/60 V, VF = 0.55 V max @ 3 A, IR = 0.3 mA max - slightly tighter leakage spec. | Same thermal performance; lead-free plating differs (NiPdAu vs. matte tin), affecting solder joint reliability in high-reliability reflow. | Prefer for aerospace or medical designs requiring NiPdAu termination and tighter IR control. |
Compared with SS36-E3/57T and MBR360FCT, the B360AX-13 delivers the lowest VF among SMA-packaged 3A/60V Schottkys, making it optimal for efficiency-critical, thermally constrained DC-DC and adapter designs where 0.03–0.12 V VF reduction directly improves thermal margin and light-load behavior.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The B360AX-13 has a rated maximum junction temperature of +150°C. Continuous operation at this limit requires strict thermal management - including adequate copper area, minimal trace length, and ambient temperature control - as specified in the thermal derating curve (Figure 4). Exceeding +150°C risks permanent parametric shift or catastrophic failure.
Is the B360AX-13 suitable for automotive applications?
The B360AX-13 is not AEC-Q101 qualified and is not recommended for safety-critical automotive functions. However, it may be used in non-safety automotive accessories (e.g., infotainment USB chargers) if customer-validated for the specific environment. For qualified parts, Diodes offers AEC-Q101 versions like B360AHE3/5BT.
How does the SMA package affect PCB layout and thermal performance?
The SMA (DO-214AC) package requires a minimum 0.2" × 0.25" copper pad per Diodes' recommended layout to achieve RθJA = 65°C/W. Smaller pads increase thermal resistance significantly - e.g., halving pad area raises RθJA to ~90°C/W - risking premature thermal shutdown at full load.
Does the B360AX-13 have a specified junction capacitance?
Yes - typical junction capacitance is 120 pF at VR = 4 V (per Figure 3), decreasing to ~40 pF at VR = 40 V. This low CJ supports high-frequency operation up to 1 MHz with minimal capacitive loading on switching nodes, unlike higher-capacitance PN rectifiers.
