Product details
Overview
B330B-13-F from Diodes Incorporated is a 3.0A surface-mount Schottky barrier rectifier in SMB package, rated for 30V peak repetitive reverse voltage and 0.50V typical forward voltage at 3.0A, with 100A non-repetitive surge capability and AEC-Q101 qualification for automotive reliability. It serves as a low-loss freewheeling diode in DC-DC converters and polarity protection switch in 12V/24V automotive power rails.
For engineers reviewing the B330B-13-F datasheet, B330B-13-F pinout, B330B-13-F application, or B330B-13-F equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (RθJT = 25°C/W), surge rating (IFSM = 100A), and RoHS/Green compliance status - all confirmed per DS30924 Rev. 10-2.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced junction breakdown and supports automated SMT assembly due to its SMB package and matte tin lead finish. Its low forward voltage (≤0.50V @ 3.0A) minimizes conduction loss in high-frequency switching topologies.
Thermal performance is defined by RθJT = 25°C/W (junction-to-terminal) and RθJA = 95°C/W (junction-to-ambient) on standard glass-epoxy PCB with 2×3mm copper pad. Operating temperature range spans –55°C to +150°C, validated under AEC-Q101 stress testing for automotive under-hood use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum reverse blocking voltage before avalanche; sets safe operating limit in 24V system clamping and reverse polarity protection. |
| IO @ TT=100°C | 3.0 A - Continuous average forward current derated to terminal temperature; enables stable operation in compact heatsinkless designs. |
| VF @ IF=3.0A | 0.50 V typ - Low conduction loss reduces power dissipation to ≤1.5W at full load, critical for thermally constrained PCB layouts. |
| IFSM (8.3ms) | 100 A - Single half-sine surge rating; withstands inrush currents in motor drive flyback and capacitor charging circuits. |
| RθJT | 25 °C/W - Junction-to-terminal thermal resistance; allows direct thermal coupling to copper pour or metal-core PCB for passive cooling. |
| IR @ VR=30V | 0.5 mA max @ 25°C - Low leakage preserves battery standby life in always-on automotive modules. |
| CT @ VR=4V | 200 pF max - Junction capacitance limits high-frequency switching noise and EMI in SMPS snubber networks. |
Pinout & Package
Package: SMB (Surface Mount Body), molded plastic case with UL 94V-0 flammability rating, cathode band marking, and matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or return path) in freewheeling configuration; must route with low-inductance trace. |
| Cathode | Forward current exit / reverse voltage blocking node | Marked with band; ties to positive rail in polarity protection; determines voltage drop direction and reverse isolation capability. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge breakdown during voltage transients, enabling reliable operation in noisy automotive environments without external TVS. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD - required for engine control, body electronics, and ADAS power stages. |
| Lead-free & Halogen-free | Meets RoHS 2 (2011/65/EU) and "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb); compliant with global environmental manufacturing mandates. |
| SMB package footprint | Standardized 4.3×2.5mm outline with 5.3mm length; compatible with industry-standard pick-and-place nozzles and reflow profiles (J-STD-020 Level 1). |
Applications
| Automotive Power Rail Protection | DC-DC Converter Freewheeling |
|---|---|
Use Scenario: Reverse polarity connection protection in 12V/24V vehicle infotainment head units and telematics gateways. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed in series with input power line to prevent damage from accidental battery reversal. Use Value: 30V VRRM safely blocks reverse battery voltage; 0.50V VF ensures minimal insertion loss (<1.5W at 3A), preserving system efficiency. |
Use Scenario: Freewheeling path in synchronous buck converter output stage for industrial PLC power supplies. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during high-side MOSFET off-time to maintain continuous inductor current. Use Value: Low VF and fast recovery eliminate reverse recovery charge, reducing switching losses and EMI compared to PN rectifiers. |
| Low-Voltage Polarity Guard | High-Frequency Inverter Output |
Use Scenario: Input polarity safeguard in portable medical battery chargers operating from 5–12V DC sources. IC Role / Device Role / Timing Role: Series-connected Schottky diode ensuring only correct-polarity input reaches downstream LDOs and microcontrollers. Use Value: 3.0A IO rating supports peak charging currents; AEC-Q101 qualification adds robustness for field-deployed equipment. |
Use Scenario: Output rectification in 100kHz+ resonant LLC inverters for LED street lighting drivers. IC Role / Device Role / Timing Role: Converts high-frequency AC output to DC while minimizing conduction loss and thermal rise. Use Value: 200pF CT limits displacement current at 1MHz; 100A IFSM handles startup surges without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS33 (Vishay) | Same SMB package, 30V VRRM, but VF = 0.52V typ @ 3A; RθJA = 100°C/W vs. 95°C/W. | Marginally higher thermal resistance limits power density in dense layouts; identical AEC-Q101 status. | Prefer B330B-13-F where board space or thermal margin is constrained. |
| SB330 (ON Semiconductor) | 30V VRRM, VF = 0.55V typ @ 3A; IFSM = 80A (vs. 100A); not AEC-Q101 qualified. | Lacks automotive qualification; lower surge rating reduces robustness in motor-driven loads. | Acceptable for commercial-grade 12V adapters but not for automotive or industrial safety-critical systems. |
Compared with SS33 and SB330, B330B-13-F delivers superior surge immunity (100A), tighter thermal resistance (RθJA = 95°C/W), and verified AEC-Q101 compliance - making it the preferred choice for automotive and high-reliability industrial rectification where transient resilience and long-term stability are mandatory.

FAQ
Is B330B-13-F suitable for automotive applications?
Yes. B330B-13-F is AEC-Q101 qualified and PPAP capable, with tested performance across –55°C to +150°C operating range, guard ring die for transient suppression, and full RoHS/Green compliance - meeting requirements for engine control units, body electronics, and ADAS power stages.
What is the maximum continuous forward current at 100°C terminal temperature?
The maximum average rectified output current IO is 3.0A when terminal temperature (TT) is maintained at +100°C, as specified in DS30924 Rev. 10-2. Derating begins above this temperature per Figure 6, reaching ~1.8A at +125°C TT.
Does B330B-13-F have a cathode band marking?
Yes. The device features a visible cathode band on the package body, consistent with SMB mechanical drawings in DS30924. This band identifies the cathode terminal and must be aligned with the PCB silkscreen polarity indicator during placement.
Can B330B-13-F replace B340B-13-F in a 40V design?
No. B330B-13-F has VRRM = 30V and is not rated for 40V blocking. Substituting it in a 40V circuit risks reverse breakdown and catastrophic failure. Use B340B-13-F (40V) or B350B-13-F (50V) for higher reverse voltage requirements.
