Product details
Overview
B330AE-13 from Diodes Incorporated is a 30 V, 3 A surface-mount Schottky barrier rectifier in SMA 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 boost stages in power supplies.
For engineers reviewing the B330AE-13 datasheet, B330AE-13 pinout, B330AE-13 application, or B330AE-13 equivalent, key selection criteria include its low VF for reduced conduction loss, stable IR at elevated temperatures, SMA thermal performance (RθJA = 60°C/W), and RoHS-compliant matte tin terminations.
Technical Context
This Schottky rectifier uses a planar epitaxial construction to achieve low forward voltage and controlled junction capacitance (140 pF at 4 V). Its low reverse recovery charge enables high-frequency switching operation without significant switching loss penalties.
The device operates across –55°C to +150°C with derated current above +25°C (e.g., ~2.2 A at +100°C), and exhibits thermally stable leakage-0.15 mA at +25°C rising to ≤35 mA at +125°C under 45 V bias-supporting reliable operation in thermally constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage before breakdown |
| IO(AV) | 3 A - Continuous average forward current on FR-4 PCB with 0.56"×0.73" copper pad |
| VF(max) | 0.50 V @ 3 A, +25°C - Limits conduction loss to ≤1.5 W at full load |
| IR(max) | 0.15 mA @ 30 V, +25°C - Enables low standby power in blocking configurations |
| RθJA | 60 °C/W - Junction-to-ambient thermal resistance defines heatsinking requirement |
| CT | 140 pF @ 4 V, 1 MHz - Low junction capacitance minimizes switching node ringing |
Pinout & Package

|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in boost converter) |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to output rail; blocks reverse current during off-state |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.50 V max at 3 A ensures <1.5 W conduction loss at full rated current |
| High-temperature leakage stability | 0.15 mA @ +25°C, ≤35 mA @ +125°C supports thermal reliability in enclosed enclosures |
| Lead-free & green construction | Matte tin annealed over copper leadframe; halogen/antimony-free per Diodes Inc. definition |
| SMA package thermal performance | RθJC = 30°C/W enables efficient heat transfer to PCB copper when mounted per recommended pad layout |
Applications
| Boost Diode | Blocking Diode |
|---|---|
Use Scenario: Used in non-isolated DC/DC boost converters to transfer energy from input to output capacitor during switch-off phase. IC Role / Device Role / Timing Role: Unidirectional current path enabling inductor energy transfer; conducts only when switch is off and output voltage exceeds input. Use Value: 0.5 V VF reduces power loss by ~30% vs. standard PN rectifiers, improving efficiency and reducing thermal stress on adjacent ICs. | Use Scenario: Placed between battery and system rail to prevent backfeed during battery removal or fault conditions. IC Role / Device Role / Timing Role: Reverse polarity protection element; blocks current flow from system to battery when battery voltage drops below rail. Use Value: 0.15 mA IR at +25°C limits standby drain, extending shelf life of backup batteries in industrial controllers. |
| Recirculating Diode | OR-ing Diode |
Use Scenario: Provides freewheeling path for inductive loads (e.g., solenoids, relays) after driver turn-off. IC Role / Device Role / Timing Role: Clamp inductive kickback voltage to safe levels; conducts only during flyback transient. Use Value: Fast recovery (no stored charge) eliminates reverse recovery spikes, reducing EMI in motor control PCBs. | Use Scenario: Used in redundant power supply designs to isolate parallel inputs while allowing seamless switchover. IC Role / Device Role / Timing Role: Forward-biased path selector; conducts only when its anode voltage exceeds cathode by >VF. Use Value: Low VF minimizes voltage drop between sources, preserving regulation margin in 5 V or 3.3 V OR-ing applications. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB330-E3/57T (Vishay) | Same 30 V / 3 A rating; VF = 0.52 V max; RθJA = 65°C/W; SMA package | Higher VF increases conduction loss by ~40 mW at 3 A; slightly higher thermal resistance | Acceptable where margin exists in thermal design and efficiency targets allow 0.02 V VF penalty |
| SS33 (ON Semiconductor) | 30 V / 3 A; VF = 0.5 V max; RθJA = 55°C/W; SMA package; RoHS compliant | Lower RθJA improves thermal headroom; identical VF and leakage specs | Preferred for thermally dense layouts requiring better junction-to-ambient dissipation |
Compared with SB330-E3/57T, B330AE-13 offers tighter thermal resistance and lower leakage; versus SS33, it provides equivalent electrical performance but differs in leadframe metallurgy and moisture sensitivity level (B330AE-13: J-STD-020 Level 1).

FAQ
What is the maximum junction temperature for continuous operation of B330AE-13?
The B330AE-13 has a specified operating junction temperature range of –55°C to +150°C. Continuous operation at +150°C requires strict adherence to derated current limits-approximately 1.5 A at +125°C and ~1.0 A at +150°C per Figure 4 in DS39236 Rev. 3–2.
Is B330AE-13 suitable for use in automotive under-hood applications?
Yes-B330AE-13 meets AEC-Q101 stress test requirements for discrete semiconductors and operates up to +150°C. Its low IR drift with temperature and robust SMA package make it appropriate for engine control modules and body electronics where ambient temperatures exceed +105°C.
Does B330AE-13 require a heatsink for 3 A DC operation?
No external heatsink is required for 3 A DC operation at +25°C ambient when mounted on a standard FR-4 PCB with the recommended 0.56"×0.73" copper pad. At +70°C ambient, junction temperature reaches ~120°C-within rating-but thermal derating to ~2.2 A is advised for long-term reliability.
How does the cathode band orientation correspond to the SMA package outline?
The cathode band is located on the top surface of the SMA package, aligned with the flat edge of the molded case. When viewed from above with the band at the left, the anode is the left lead and the cathode is the right lead-matching the standard DO-214AC pinout convention used across Diodes Incorporated's SMA rectifiers.
