Product details
Overview
B130L-13-F from Diodes Incorporated is a 1.0A surface-mount Schottky barrier rectifier in SMA package, featuring 30V peak repetitive reverse voltage, 0.43V typical forward voltage at 1.0A/100°C, and 25A non-repetitive surge current capability - deployed in DC-DC converter output stages and low-voltage power supplies for portable electronics.
For engineers reviewing the B130L-13-F datasheet, B130L-13-F pinout, B130L-13-F application, or B130L-13-F equivalent, key selection criteria include forward voltage drop at elevated temperature, thermal resistance (27°C/W), leakage current behavior up to 100°C, and compatibility with automated SMT assembly on space-constrained PCBs.
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced avalanche breakdown and improve reliability under voltage spikes. Its low VF minimizes conduction loss in high-frequency switching topologies where duty cycle and thermal management are critical.
The device operates across –55°C to +125°C junction temperature range and exhibits 110pF total capacitance at 4V reverse bias and 1MHz - enabling stable performance in buck converter freewheeling paths and reverse-polarity protection circuits without excessive ringing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum blocking voltage before breakdown; sets upper limit for input/output rail separation in 24V systems |
| IO | 1.0 A - Continuous average rectified current at 105°C case temperature; defines steady-state power delivery capacity |
| VF @ 1.0A/100°C | 0.43 V - Confirmed forward drop under thermal stress; directly determines conduction loss (0.43W) and heatsink requirements |
| RθJT | 27 °C/W - Junction-to-terminal thermal resistance; enables direct PCB copper area estimation for thermal relief |
| IFSM | 25 A - Peak non-repetitive surge rating for 8.3ms half-sine; supports inrush current handling during hot-plug events |
| CT @ 4V/1MHz | 110 pF - Junction capacitance affecting high-frequency switching noise and EMI filter design in SMPS outputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB130-E3/52T | Same SMA package, 30V VRRM, but VF = 0.52V @ 1.0A/25°C; higher thermal resistance (30°C/W) | Higher conduction loss limits use in thermally constrained designs above 60°C ambient | Select when cost sensitivity outweighs thermal performance; verify derating at 105°C case |
| SS13HE3_A/H | 1.0A/30V Schottky in SMA, VF = 0.45V @ 1.0A/125°C; tighter IR spec (≤0.5mA @ 30V/25°C) | Lower leakage supports battery-backed circuits requiring <1µA standby drain | Prefer for always-on subsystems; confirm layout compatibility with slightly different die pad geometry |
Compared with SB130-E3/52T and SS13HE3_A/H, B130L-13-F delivers the lowest VF at elevated temperature and best thermal resistance - making it optimal for high-efficiency, high-temperature DC-DC outputs where conduction loss dominates thermal budget.

FAQ
Is B130L-13-F qualified for automotive applications?
No - B130L-13-F is not AEC-Q101 qualified. While it operates from –55°C to +125°C and meets RoHS/Green requirements, Diodes explicitly states that automotive-grade versions require separate PPAP-capable part numbers and IATF 16949 manufacturing. This part is intended for industrial and commercial use only.
What is the maximum recommended PCB copper area for thermal relief at 1.0A continuous?
Based on RθJT = 27°C/W and 105°C max case temperature, a minimum 40 mm² of 2-oz copper connected to both terminals reduces thermal resistance to ~15°C/W. The datasheet's Fig. 4 shows 1.0A derates to zero at 125°C case, confirming need for adequate copper pour or thermal vias beneath the SMA pad.
Does B130L-13-F have a specified reverse recovery time (trr)?
No - Schottky rectifiers like B130L-13-F are majority-carrier devices with no minority-carrier storage delay; trr is not defined or tested. Instead, its 110pF junction capacitance and low leakage govern high-frequency switching behavior - making it suitable for >100kHz SMPS without reverse recovery losses.
Can B130L-13-F replace a 1N5819 in existing designs?
Yes - B130L-13-F matches 1N5819's 30V/1A rating and SMA footprint, but offers lower VF (0.43V vs. 0.45–0.6V), better thermal resistance (27 vs. ~35°C/W), and tighter leakage specs. Layout is identical; no redesign needed unless legacy 1N5819 was used in >125°C environments where B130L's 125°C TJ limit applies.
