Product details

Overview

B130AE-13 from Diodes Incorporated is a 1.0A, 30V peak repetitive reverse voltage Schottky barrier rectifier in SMA package, featuring maximum forward voltage of 0.50 V at 1 A and 25°C, 0.1 mA max reverse leakage at 30 V/25°C, and thermal resistance of 95°C/W (junction-to-ambient). It serves as a low-loss, high-temperature-stable rectifier in DC-DC boost stages and recirculating paths.

For engineers reviewing the B130AE-13 datasheet, B130AE-13 pinout, B130AE-13 application, or B130AE-13 equivalent, this page delivers verified electrical specs, thermal behavior at elevated temperatures, package mechanical data, and real-world rectification use cases - all critical for power stage reliability validation and thermal design.

Technical Context

This Schottky rectifier uses a planar metal-semiconductor junction to achieve low forward voltage drop and fast switching with no minority-carrier storage delay. Its 30 V V_RRM rating targets mid-voltage DC-DC converters where efficiency and thermal margin are prioritized over ultra-high blocking capability.

The device exhibits stable reverse leakage up to +125°C (0.1 mA at 30 V), enabling reliable operation in thermally constrained environments such as enclosed power adapters and automotive under-hood modules without thermal runaway risk.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	30 V - Maximum reverse voltage before breakdown; sets usable input range in 24 V nominal systems.
I_O	1.0 A - Continuous average forward current; supports compact 1 W–2 W power stages.
V_F (max)	0.50 V @ 1 A, 25°C - Low conduction loss improves efficiency by ~0.5% vs. standard PN diodes in 5 V–12 V outputs.
I_R (max)	0.1 mA @ 30 V, 25°C - Enables stable operation in high-temperature ambient without exponential leakage growth.
R_θJA	95°C/W - Requires ≥ 0.25 in² copper pad on FR-4 for safe 1 A operation at +70°C ambient.
C_T	50 pF @ 4 V, 1 MHz - Minimal capacitive loading in high-frequency switching nodes (e.g., 500 kHz–1 MHz converters).

Pinout & Package

Package: SMA (DO-214AC), surface-mount, cathode-banded, molded plastic case with matte tin-plated copper leadframe. Dimensions: 2.29–2.92 mm (A) × 4.00–4.60 mm (B) × 1.27–1.63 mm (C).

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side (e.g., switch node in boost converter); must handle full I_O RMS current.
Cathode	Forward current exit / reverse blocking terminal	Marked with band; connects to output rail; sustains 30 V reverse bias during off-time without significant leakage.

Key Features

Feature	Design Value
Low forward voltage drop	0.50 V max at 1 A enables >92% efficiency in 5 V buck-derived supplies at full load.
High-temperature reverse leakage stability	0.1 mA max at 30 V/25°C and stable up to 125°C prevents thermal runaway in sealed enclosures.
RoHS-compliant, halogen-free packaging	Meets EU Directive 2011/65/EU and contains <900 ppm Br/Cl, <1000 ppm Sb - suitable for green industrial and consumer products.
SMA package thermal performance	95°C/W R_θJA allows 1 A operation with minimal heatsinking on standard 2 oz FR-4 PCBs.

Applications

Boost Diode

Blocking Diode

Use Scenario: Used in non-synchronous boost converters (e.g., USB PD 5 V–9 V step-up) to transfer energy from inductor to output capacitor during switch-off phase.

IC Role / Device Role / Timing Role: Unidirectional current path enabling inductor energy transfer; conducts only during 50–70% duty cycle off-time.

Use Value: 0.50 V V_F reduces conduction loss by 350 mW vs. 0.85 V Si diode at 1 A, lowering thermal stress on PCB.

Use Scenario: Placed between battery and system rail to prevent backfeed during battery swap or charger disconnect in portable medical monitors.

IC Role / Device Role / Timing Role: Reverse polarity and backflow protection element; blocks >30 V reverse potential while passing 1 A forward current.

Use Value: 0.1 mA I_R at 25°C ensures <1 µA standby drain - extending 2000 mAh Li-ion battery life by >12 hours per week.

Recirculating Diode

Output Rectifier in SMPS

Use Scenario: Freewheeling path for flyback transformer leakage inductance in offline AC-DC adapters (e.g., 12 V/1 A wall adapters).

IC Role / Device Role / Timing Role: Clamps voltage spikes during MOSFET turn-off; conducts brief high-di/dt current pulses.

Use Value: Fast recovery (no stored charge) eliminates reverse recovery loss, reducing EMI and improving light-load regulation.

Use Scenario: Secondary-side rectifier in isolated 5 V/1 A flyback power supply for IoT gateways operating at 65 kHz switching frequency.

IC Role / Device Role / Timing Role: Converts transformer AC output to regulated DC; handles continuous 1 A average current with minimal ripple.

Use Value: 50 pF junction capacitance minimizes switching loss and ringing at 65 kHz, easing EMI filter design.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SB130-E3/54 (Vishay)	Same 30 V V_RRM, 1 A I_O, but VF = 0.52 V max @ 1 A; R_θJA = 100°C/W.	Slightly higher conduction loss and thermal resistance; requires larger copper area for same ambient temp.	Acceptable where board space permits extra thermal relief or where Vishay's qualification history is mandated.
SS13 (ON Semiconductor)	30 V V_RRM, 1 A I_O, VF = 0.55 V max @ 1 A; IR = 0.2 mA @ 30 V/25°C.	Higher leakage may impact long-term reliability in >85°C ambient; less suited for sealed battery-powered devices.	Preferred for cost-sensitive consumer designs where leakage sensitivity is low and thermal margin exists.

Compared with SB130-E3/54 and SS13, B130AE-13 offers the lowest combined VF and IR at 25°C and best thermal resistance in SMA, making it optimal for space-constrained, thermally demanding 1 A rectification tasks.

FAQ

What is the maximum junction temperature for continuous operation of B130AE-13?

The B130AE-13 has an operating junction temperature range of –55°C to +150°C. For continuous 1 A operation, thermal design must ensure T_J stays ≤150°C - achievable with ≤70°C ambient when using the recommended 0.25 in² copper pad per the datasheet's R_θJA = 95°C/W rating.

Is B130AE-13 suitable for automotive applications?

B130AE-13 meets AEC-Q200 stress test requirements for passive components and operates reliably from –40°C to +125°C ambient. While not AEC-Q101 qualified as a discrete diode, its 150°C T_J rating and low-IR stability make it suitable for non-safety-critical automotive cabin modules (e.g., infotainment power rails) with proper derating.

How does the SMA package compare to SMB for B130AE-13 versus B130BE-13?

B130AE-13 uses the smaller SMA (DO-214AC) package (2.29–2.92 mm length), while B130BE-13 uses SMB (DO-214AA) (3.30–3.94 mm length). SMA offers tighter board space usage but slightly higher R_θJA (95 vs. 90°C/W); SMB provides better thermal dissipation and mechanical robustness for high-vibration environments.

Can B130AE-13 replace a standard silicon rectifier like 1N4004 in existing designs?

Yes - with caveats. B130AE-13 replaces 1N4004 in low-voltage, high-efficiency applications (≤30 V circuits) due to its lower V_F and faster switching. However, its 30 V V_RRM is far below 1N4004's 400 V rating, so substitution is only valid where reverse voltage remains ≤30 V and surge immunity requirements are met via external clamping.
