Product details
Overview
B330CE-13 from Diodes Incorporated is a 30 V, 3 A surface-mount Schottky barrier rectifier in SMC package, featuring 0.5 V max forward voltage at 3 A and 0.15 mA max reverse leakage at 30 V and +25°C, optimized for high-efficiency DC/DC converter output rectification in industrial power supplies.
For engineers reviewing the B330CE-13 datasheet, B330CE-13 pinout, B330CE-13 application, or B330CE-13 equivalent, key selection criteria include low VF for thermal management, high-temperature IR stability for reliability in enclosed environments, SMC package thermal resistance (RθJC = 30°C/W), and RoHS-compliant matte tin terminations.
Technical Context
This Schottky rectifier uses a platinum-silicide or similar low-barrier metal-semiconductor junction to achieve low forward voltage drop while maintaining controlled reverse leakage. Its design targets continuous conduction mode (CCM) and discontinuous conduction mode (DCM) flyback and buck-derived topologies where fast recovery and minimal switching loss are critical.
The device operates across –55°C to +150°C junction temperature range with thermal resistance junction-to-case of 30°C/W (SMC), enabling direct heatsink mounting in high-power-density designs. Reverse leakage remains stable up to 125°C, mitigating thermal runaway risk in ambient temperatures exceeding 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse voltage before breakdown; sets safe operating limit in boost or flyback secondary circuits. |
| IO(AV) | 3 A - Average forward current rating at TA = +25°C; derates to ~1.8 A at +100°C per Figure 4. |
| VF(max) | 0.5 V @ 3 A, +25°C - Low conduction loss improves efficiency by ~0.5–1.2% vs. standard PN diodes in 12 V output rails. |
| IR(max) | 0.15 mA @ 30 V, +25°C - Enables stable operation in high-impedance bias networks and low-power standby circuits. |
| RθJC | 30°C/W - Junction-to-case thermal resistance supports direct thermal pad attachment for >2 W dissipation without forced air. |
| CT | 140 pF @ 4 V, 1 MHz - Low junction capacitance minimizes switching node ringing in high-frequency (>300 kHz) converters. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with matte tin–annealed copper leadframe, cathode band marking, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction path | Connected to lower-potential node (e.g., switch node in synchronous buck, transformer center-tap in full-wave). |
| Cathode | Output terminal for forward conduction path | Connected to output rail or filter capacitor; marked with band; carries full load current and must be routed with low-inductance layout. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.5 V max at 3 A ensures <0.75 W conduction loss at full load, reducing heatsink requirements in space-constrained 24 V input supplies. |
| High-temperature leakage stability | IR ≤ 30 mA at VR = 45 V and TJ = +150°C (typical curve) enables reliable operation in sealed enclosures above 85°C ambient. |
| Green compound packaging | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) meets IPC-1752A environmental compliance reporting needs. |
| Solderable terminations | Matte tin annealed over copper leadframe complies with MIL-STD-202 Method 208, supporting lead-free reflow profiles up to 260°C peak. |
Applications
| Boost Diode in PFC Stage | Blocking Diode in Solar Charge Controller |
|---|---|
Use Scenario: Used in continuous conduction mode (CCM) boost PFC stage of 300 W industrial AC/DC front-end. IC Role / Device Role / Timing Role: Unidirectional current path during MOSFET off-time; handles 3 A average output current at 30–40 V output. Use Value: 0.5 V VF reduces conduction loss by 1.5 W vs. Si PN diode, lowering thermal stress on heatsink and improving system efficiency by 0.8%. | Use Scenario: Prevents reverse current flow from battery to PV panel at night in 24 V nominal solar charge controller. IC Role / Device Role / Timing Role: Standby-blocking element; sustains 30 V reverse bias with <0.15 mA leakage at room temperature. Use Value: Low IR prevents >1 mAh/night battery drain, extending usable battery capacity in off-grid systems. |
| Recirculating Diode in DC Motor Driver | Output Rectifier in Isolated Flyback Supply |
Use Scenario: Freewheeling path for inductive kickback in 24 V brushed DC motor H-bridge driver (3 A stall current). IC Role / Device Role / Timing Role: Clamps inductive voltage spike during MOSFET turn-off; conducts transient current for <10 µs duration. Use Value: Fast intrinsic recovery and low VF minimize voltage overshoot and reduce snubber losses by ~30% vs. standard FR diodes. | Use Scenario: Secondary-side rectifier in 12 V/2.5 A isolated flyback supply for industrial PLC I/O module. IC Role / Device Role / Timing Role: Converts transformer AC output to regulated DC; operates at 65 kHz switching frequency with 3 A peak current. Use Value: 140 pF CT limits high-frequency ringing, easing EMI filter design and reducing need for RC snubbers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS33HE3/57T | Same 30 V/3 A rating; VF = 0.5 V @ 3 A, but RθJC = 40°C/W (SMA); IR = 0.2 mA @ 30 V. | Higher thermal resistance limits power handling in thermally constrained layouts; slightly higher leakage affects ultra-low-power standby. | Select when SMA footprint compatibility is required and thermal margin ≥15°C exists. |
| MBR330G | 30 V/3 A; VF = 0.54 V @ 3 A; RθJC = 25°C/W (TO-220AC); IR = 0.25 mA @ 30 V; through-hole only. | Superior thermal performance but requires PCB real estate and wave soldering; not suitable for fully SMT designs. | Select for high-reliability, high-ambient-temperature applications where board space permits through-hole mounting. |
Compared with SS33HE3/57T and MBR330G, B330CE-13 offers optimal balance of low VF, industry-leading RθJC (30°C/W), and SMC's compact SMT footprint-making it preferred for high-density, convection-cooled industrial power modules where thermal and spatial constraints coexist.

FAQ
What is the maximum junction temperature for continuous operation?
The B330CE-13 has an operating junction temperature range of –55°C to +150°C. Continuous operation at +150°C is permitted provided thermal design maintains actual TJ ≤ +150°C under worst-case ambient and power dissipation conditions, verified using RθJA = 70°C/W (SMC on FR-4) or RθJC = 30°C/W with heatsinking.
Is B330CE-13 suitable for use in automotive applications?
B330CE-13 is not AEC-Q101 qualified and lacks automotive-specific qualification testing (e.g., HTOL, TCT, ESD). While its –55°C to +150°C rating meets automotive under-hood temperature ranges, Diodes Incorporated does not endorse or guarantee its use in safety-critical or automotive OEM applications without additional customer validation.
How does the SMC package compare thermally to SMB for this part?
SMC (RθJC = 30°C/W) provides 40% lower junction-to-case thermal resistance than SMB (RθJC = 50°C/W) for the same B330x series. This allows ~1.4× higher power dissipation before reaching TJ(max), making SMC preferred for >1.5 W continuous operation or high-ambient environments.
Can B330CE-13 replace B330BE-13 in existing designs?
Yes-B330CE-13 and B330BE-13 share identical electrical specifications and thermal characteristics, differing only in package (SMC vs. SMB) and marking code. Layout redesign is required to accommodate SMC's larger footprint (6.22 × 7.11 mm vs. SMB's 3.94 × 4.57 mm), but no circuit requalification is needed for parametric performance.
