Diodes Incorporated B230AE-13

Overview

B230AE-13 from Diodes Incorporated is a 30 V, 2 A surface-mount Schottky barrier rectifier in SMA package, featuring maximum forward voltage of 0.50 V at 2 A and reverse leakage current of 0.1 mA at 30 V and +25°C. It delivers low conduction loss and stable high-temperature reverse blocking for DC/DC converter output rectification, boost diode applications, and recirculating paths in automotive body control modules.

For engineers reviewing the B230AE-13 datasheet, B230AE-13 pinout, B230AE-13 application, or B230AE-13 equivalent, key selection criteria include its 30 V VRRM rating, 2 A IO capability, thermal resistance (RθJA = 95 °C/W), junction-to-case thermal path, and RoHS-compliant matte tin finish on copper leadframe.

Technical Context

This Schottky rectifier uses a planar metal–semiconductor junction optimized for low VF and minimal IR drift up to +150°C. Its design targets high-efficiency, medium-current power conversion where fast switching and reduced forward conduction loss are critical-especially in space-constrained 12 V and 24 V automotive and industrial DC/DC stages.

The device operates with no minority-carrier storage delay, enabling zero-recovery behavior under commutation. Its 93 pF typical junction capacitance at 4 V reverse bias supports moderate-frequency (<1 MHz) switching while maintaining low EMI generation in buck-boost and flyback secondary-side rectification.

FAQ

What is the maximum junction temperature for continuous operation of B230AE-13?

The B230AE-13 has an operating junction temperature range of –55°C to +150°C. For reliable continuous operation at 2 A, ambient temperature must be limited to ≤+100°C when mounted on a standard FR-4 PCB (per Figure 4 derating curve), given its 95 °C/W RθJA and 0.50 V VF-induced self-heating.

Is B230AE-13 suitable for use in synchronous rectification topologies?

No - B230AE-13 is a passive Schottky rectifier, not a controlled switch. It lacks gate drive capability and cannot replace MOSFETs in synchronous rectification. Its zero reverse recovery makes it ideal for asynchronous rectification where simplicity and cost outweigh efficiency gains from active switching.

Does B230AE-13 require a heatsink in typical 2 A applications?

Not under standard conditions: with 2 A DC current and 0.50 V VF, power dissipation is ~1.0 W. On a 0.4" × 0.5" 2 oz FR-4 pad (RθJA = 95 °C/W), junction rise is ~95°C above ambient - acceptable up to +55°C ambient. Heatsinking is unnecessary unless ambient exceeds +60°C or layout restricts copper area.

How does the SMA package of B230AE-13 compare electrically to the SMB variant B230BE-13?

Electrically identical: same VRRM (30 V), IO (2 A), VF (≤0.50 V), IR (≤0.1 mA), and CT (93 pF). The only differences are mechanical - SMB offers 5 °C/W lower RθJA (90 vs. 95 °C/W) and larger footprint; SMA enables denser layouts with slightly higher thermal resistance.
