Product details

Overview

B330Q-13-F from Diodes Incorporated is a 30 V, 3.0 A surface-mount Schottky barrier rectifier in SMC package, featuring 0.5 V max forward voltage at 3.0 A, 0.5 mA max reverse leakage at rated VR, and AEC-Q101 qualification for automotive use in polarity protection and freewheeling circuits.

For engineers reviewing the B330Q-13-F datasheet, B330Q-13-F pinout, B330Q-13-F application, or B330Q-13-F equivalent, key selection criteria include peak repetitive reverse voltage (30 V), average rectified output current (3.0 A), thermal resistance junction-to-terminal (20 °C/W), and RoHS-compliant lead-free plating with cathode band polarity marking.

Technical Context

This Schottky rectifier uses guard ring die construction to enhance transient immunity and supports automated SMT assembly. Its low VF (0.5 V max) and low IR (0.5 mA max at 25°C) enable high-efficiency operation in low-voltage DC/DC stages and reverse-polarity protection paths.

Rated for -55°C to +150°C operating temperature and qualified per AEC-Q101, it delivers stable performance under automotive thermal cycling and vibration stress. The SMC package provides 20 °C/W typical R_θJT, enabling reliable power dissipation up to 3.0 A continuous forward current with proper PCB copper pad design.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	30 V - maximum repetitive reverse blocking voltage; defines safe operating limit in polarity protection and flyback clamp applications
I_O	3.0 A - average rectified forward current; supports continuous conduction mode in 12 V automotive power rails
V_F max	0.5 V @ 3.0 A - low forward drop reduces conduction loss by >40% vs. standard PN rectifiers, improving system efficiency
I_R max	0.5 mA @ 30 V, 25°C - minimal leakage preserves battery standby life in always-on vehicle modules
R_θJT	20 °C/W - enables direct thermal path to PCB copper; allows 3.0 A operation with ≤60°C junction rise on 2 mm × 3 mm pad
Qualification	AEC-Q101 - certified for automotive underhood and cabin applications requiring PPAP documentation and IATF 16949 manufacturing control

Pinout & Package

Package: SMC (DO-214AB), molded plastic, UL 94V-0, 0.21 g weight, cathode band polarity marking, matte tin lead-free plating.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry terminal	Connected to input/power source side in polarity protection; must route with low-inductance trace for high-frequency switching
Cathode	Forward current exit terminal	Marked with band; connects to load ground or return path; serves as clamping node in freewheeling diode configuration

Key Features

Feature	Design Value
Guard ring die construction	Improves ESD and surge robustness without external TVS, meeting ISO 7637-2 pulse 1/2a/3a immunity requirements
Low 0.5 V forward voltage	Reduces power loss to ≤1.5 W at 3.0 A, minimizing heatsink need in space-constrained ECUs
AEC-Q101 qualification	Validates reliability for 15-year automotive service life under thermal cycling, humidity, and mechanical shock

Applications

Body Control Module (BCM) Polarity Protection

Engine Control Unit (ECU) Freewheeling Diode

Use Scenario: Reverse-battery connection protection on 12 V supply input of BCM microcontroller power rail.

IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage during jump-start or battery replacement errors.

Use Value: 30 V V_RRM exceeds automotive load-dump transients; 0.5 V V_F limits voltage drop to <2% at full load, preserving brown-out margin.

Use Scenario: Flyback energy recirculation across solenoid driver MOSFET in fuel injector circuit.

IC Role / Device Role / Timing Role: Fast-recovery path for inductive kickback, reducing MOSFET voltage overshoot and EMI.

Use Value: Schottky architecture enables <10 ns reverse recovery, suppressing ringing and enabling higher PWM frequencies.

ADAS Camera Power Supply

Electric Power Steering (EPS) Motor Driver

Use Scenario: Input rectification and reverse protection in 5 V/3.3 V dual-rail camera module PMIC.

IC Role / Device Role / Timing Role: Primary DC input conditioning stage before LDO or buck converter.

Use Value: 0.5 mA max I_R prevents standby current drain, extending sleep-mode battery life in always-on vision systems.

Use Scenario: Clamping diode across H-bridge half-bridge switches in EPS motor phase legs.

IC Role / Device Role / Timing Role: Bidirectional energy sink during regenerative braking and direction reversal.

Use Value: 100 A I_FSM rating withstands motor stall surges; SMC package supports high-current PCB routing with 2 mm × 3 mm thermal pad.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SB330-E3/52 (Vishay)	Same 30 V V_RRM, 3.0 A I_O, but 0.55 V V_F max @ 3.0 A and no AEC-Q101 qualification	Not approved for automotive production; limited to industrial or consumer-grade designs	Select when AEC-Q101 is not required and 50 mV higher VF is acceptable for cost-sensitive builds
SS33-A (ON Semiconductor)	30 V V_RRM, 3.0 A I_O, 0.52 V V_F max, AEC-Q101 qualified, but SMC package has different thermal pad layout	Requires PCB footprint revision due to alternate SMC variant (DO-214AB variant with modified land pattern)	Select only if redesigning PCB layout; verify R_θJA (90 °C/W) matches thermal budget with new pad geometry

Compared with SB330-E3/52 and SS33-A, B330Q-13-F offers the lowest forward voltage (0.50 V) among AEC-Q101-qualified 3 A Schottkys and maintains strict IATF 16949 traceability-critical for Tier 1 automotive procurement and PPAP submission.

FAQ

What is the maximum junction temperature and how does it affect continuous current rating?

The B330Q-13-F has a maximum junction temperature of +150°C and an operating range from -55°C to +150°C. At 25°C ambient, its 3.0 A rating assumes adequate PCB copper area (2 mm × 3 mm pad) to maintain R_θJT = 20 °C/W. Derating begins above 25°C ambient per Fig. 6, reaching ~1.8 A at 100°C ambient.

Is the cathode band the only polarity indicator, or are there secondary markings?

The primary polarity indicator is the cathode band on the device body. Per datasheet Note 5, a cathode notch may also be present. Marking includes "B330" product code and a YWW date code (e.g., "623" = 2026, week 23); no anode-specific marking is used.

Does this part support reflow soldering, and what profile is recommended?

Yes, B330Q-13-F is qualified for lead-free reflow per J-STD-020. It has Moisture Sensitivity Level 1, requiring no dry-pack or baking. Recommended peak temperature is 260°C max for ≤10 seconds; ramp rates and soak profiles must follow IPC-J-STD-020 Class 1 guidelines for SMC packages.

How does the 100 A I_FSM rating translate to real-world surge handling capability?

The 100 A non-repetitive peak forward surge current (8.3 ms half-sine) corresponds to automotive load dump and motor stall events. It enables survival of ISO 7637-2 Pulse 5a (12 V systems) without degradation, provided PCB traces and thermal mass limit junction temperature rise below 150°C during the event.
