Product details

Overview

B330-13-F from Diodes Incorporated is a 30 V, 3.0 A surface-mount Schottky barrier rectifier in SMC package, featuring 0.50 V max forward voltage at 3.0 A, 0.1 mA max reverse leakage at rated VR, and 100 A non-repetitive surge rating - used for polarity protection and freewheeling in DC/DC converters and power supply outputs.

For engineers reviewing the B330-13-F datasheet, B330-13-F pinout, B330-13-F application, or B330-13-F equivalent, key selection criteria include forward voltage drop at full load, thermal resistance (R_θJT = 20 °C/W), reverse voltage margin, surge capability (100 A @ 8.3 ms), and RoHS-compliant lead-free plating for automated assembly.

Technical Context

This Schottky rectifier employs guard ring die construction to suppress transient-induced junction breakdown and supports high-frequency switching due to low junction capacitance (200 pF @ 4 V). Its low VF enables reduced conduction loss in low-voltage power rails.

Rated for continuous operation from –55 °C to +150 °C, it delivers stable performance under thermal stress with R_θJA = 90 °C/W on standard FR-4 and R_θJT = 20 °C/W when mounted on copper pads - enabling compact layout in space-constrained power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	30 V - blocks up to 30 V reverse voltage without breakdown, suitable for 24 V system inputs with safety margin
I_O	3.0 A - average rectified current rating at T_A = 25 °C, derated above 75 °C per Fig. 6
V_F Max	0.50 V @ 3.0 A - limits conduction loss to ≤1.5 W at full load, critical for efficiency in 3.3–5 V output stages
I_R Max	0.1 mA @ 30 V, 25 °C - ensures minimal standby leakage in battery-backed or always-on circuits
I_FSM	100 A @ 8.3 ms - withstands inrush and short-circuit transients in SMPS and motor drive flyback paths
C_T	200 pF @ 4 V, 1 MHz - low capacitance preserves high-frequency switching integrity in >100 kHz converters
R_θJT	20 °C/W - enables direct thermal coupling to PCB copper, simplifying thermal design without heatsinks

Pinout & Package

Package: SMC (DO-214AB), molded plastic with matte tin-plated terminals, cathode band marking, moisture sensitivity level 1, weight ≈ 0.21 g.

IC Role / Device Role: Freewheeling diode providing unidirectional current path during dead time.

Use Value: 0.50 V V_F minimizes conduction loss and improves efficiency over silicon diodes; 200 pF C_T avoids switching node ringing.

Use Scenario: Installed in series with VBUS line to prevent reverse connection damage during plug insertion.

IC Role / Device Role: Unidirectional blocking element ensuring only forward current flows into device.

Use Value: 30 V V_RRM accommodates 20 V PD 3.1 extended power range; 0.1 mA I_R prevents battery drain in standby.

24 V Industrial Control Input Protection

LED Driver Flyback Clamp

Use Scenario: Mounted at PLC digital input stage to block reverse polarity from field wiring errors.

IC Role / Device Role: Polarity protection diode shunting reverse voltage before it reaches downstream logic.

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 (Vishay)	Same 30 V V_RRM, 3.0 A I_O, but VF = 0.52 V @ 3 A; R_θJA = 95 °C/W vs. 90 °C/W	Slightly higher thermal resistance requires larger pad area for same power dissipation	Preferred where Vishay qualification or alternate sourcing is required; identical footprint
SB330-E3/57T (Vishay)	30 V V_RRM, 3.0 A I_O, VF = 0.55 V @ 3 A; no guard ring; IR = 0.2 mA @ 25 °C	Higher leakage and missing guard ring reduce robustness in noisy industrial environments	Lower-cost option for non-critical consumer applications; not recommended for automotive or high-reliability use

Compared with SS33HE3/57T and SB330-E3/57T, B330-13-F offers lower forward voltage, tighter leakage control, and integrated guard ring protection - delivering superior efficiency and transient resilience in demanding power conversion and protection roles.

FAQ

What is the maximum junction temperature for continuous operation?

The B330-13-F is rated for continuous operation from –55 °C to +150 °C junction temperature. This allows reliable use in high-ambient environments such as enclosed industrial enclosures or near heat-generating components, provided thermal design meets R_θJT = 20 °C/W and board copper area supports heat dissipation.

Is B330-13-F suitable for automotive applications?

The standard B330-13-F is not automotive-qualified; however, Diodes offers the pin-compatible B330Q-13-F variant, which is AEC-Q101 qualified and specified for automotive-grade temperature cycling, humidity, and mechanical shock testing - required for under-hood or infotainment power rail use.

How does the guard ring construction improve reliability?

The guard ring die structure surrounds the active junction to distribute electric field gradients during reverse bias, preventing premature edge breakdown under fast transient conditions like inductive kickback or ESD events - extending operational life in switching power supplies and motor control circuits.

Can B330-13-F be used in parallel for higher current handling?

Parallel operation is not recommended without individual current-sharing resistors, as Schottky diodes exhibit negative temperature coefficient behavior - causing thermal runaway if mismatched. For >3.0 A requirements, select a higher-rated part (e.g., B530-13-F) or verify matched V_F binning and thermal coupling in prototype testing.
