Product details
Overview
B230Q-13-F from Diodes Incorporated is a 30 V, 2.0 A surface-mount Schottky barrier rectifier in SMB package, with 0.5 V max forward voltage at 2.0 A and 0.5 mA max reverse leakage at 25°C, designed for polarity protection and freewheeling in low-voltage DC/DC converters.
For engineers reviewing the B230Q-13-F datasheet, B230Q-13-F pinout, B230Q-13-F application, or B230Q-13-F equivalent, key selection criteria include its 30 V peak repetitive reverse voltage, 50 A non-repetitive surge rating, AEC-Q101 qualification, RoHS-compliant matte tin plating, and SMB thermal resistance of 20 °C/W junction-to-lead.
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 @ 2.0 A) minimizes conduction loss in high-frequency switching paths, while its 200 pF capacitance at 40 V enables stable operation in <1 MHz power stage snubbing and flyback clamp circuits.
Rated for -65°C to +150°C operation, it delivers full 2.0 A average current up to +125°C ambient when mounted on FR-4 with recommended pad layout. The SMB package provides 80 °C/W junction-to-ambient thermal resistance under standard test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - blocks up to 30 V reverse voltage without breakdown in polarity protection or blocking applications |
| IO | 2.0 A - continuous DC output current capability at TA = +25°C, derated per Fig. 4 |
| VF Max | 0.5 V @ 2.0 A - ensures ≤1.0 W conduction loss in 2.0 A load paths, critical for thermal management |
| IR Max | 0.5 mA @ 25°C - limits standby power loss in always-on systems such as automotive body controllers |
| IFSM | 50 A @ 8.3 ms - withstands inrush surges in DC input stages without failure |
| RθJL | 20 °C/W - enables efficient heat transfer to PCB copper in SMB footprint, supporting higher power density |
| CT | 200 pF @ 40 V, 1 MHz - defines high-frequency impedance for EMI filtering and snubber design |
Pinout & Package
SMB (Surface Mount Small Outline) package: molded plastic case, UL 94V-0 rated, cathode marked by band or notch, lead-free matte tin plating, weight ≈0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or return path) in reverse polarity protection |
| Cathode | Forward current exit point / reverse voltage blocking terminal | Connected to input supply rail; blocks reverse current flow during fault or battery reversal |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves ESD and surge immunity beyond standard Schottky diodes, enabling use in unfiltered automotive power inputs |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB230-E3/52 | Same 30 V VRRM and 2.0 A IO, but TO-277 package (higher RθJA = 100 °C/W) | Less suitable for dense SMT layouts; requires larger keep-out area | Select if legacy TO-277 footprint compatibility is required over thermal performance |
| SS23HE3_A/H | 30 V VRRM, 2.0 A IO, VF = 0.52 V, but not AEC-Q101 qualified | Not approved for automotive production; limited to commercial-grade consumer devices | Select for cost-sensitive non-automotive applications where qualification is not mandated |
Compared with SB230-E3/52 and SS23HE3_A/H, B230Q-13-F uniquely combines AEC-Q101 qualification, SMB thermal performance (20 °C/W RθJL), and RoHS/halogen-free compliance-making it the only option qualified for automotive BCM and industrial converter designs requiring both reliability and high power density.

FAQ
What is the maximum operating temperature for B230Q-13-F?
The B230Q-13-F has an operating junction temperature range of -65°C to +150°C. At ambient temperatures above +125°C, the average forward current must be derated per Figure 4 in DS38433 Rev. 3–2, with full 2.0 A rating maintained only up to +25°C ambient under specified thermal conditions.
Is B230Q-13-F suitable for use in synchronous rectification circuits?
No-B230Q-13-F is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. It functions as a freewheeling or blocking diode only. For synchronous rectification, a dedicated gate driver IC paired with a low-RDS(on) MOSFET is required.
Does B230Q-13-F require a heatsink in typical applications?
Not typically-the SMB package's 20 °C/W junction-to-lead thermal resistance allows sufficient heat dissipation into PCB copper when using the recommended pad layout (C = 4.30 mm, X = 2.50 mm, Y = 2.30 mm). Heatsinking is unnecessary unless ambient exceeds +100°C or continuous current exceeds 1.5 A with minimal copper area.
How does the guard ring construction improve reliability?
The guard ring die structure suppresses edge breakdown under high dv/dt or reverse-biased transients, increasing surge immunity and extending lifetime in automotive environments with load dump or jump-start events. This is validated through AEC-Q101 transient overload testing per stress test condition TLP-1.
